Long computer monitor cable: long monitor cable products for sale


Computer Cable types and descriptions – NO LONGER IN USE

With so many types of cables, it’s hard to find a singular source of information that highlights the important differences between them all. Here’s an overview of the most common computer cable types you’ll encounter when dealing with computers.

1. VGA Cable

Also known as D-sub cable, analog video cable

Connect one end to: computer monitor, television (PC input port)

Connect other end to: VGA port on computer (see image below)

2. DVI Cable

Connect one end to: computer monitor

Connect other end to: DVI port on computer (see image below)

However there are 2 types of DVI, DVI-I and DVI-D.
DVI-D does not have the extra pins around the long pin, this is also a pure digital signal over DVI-I.

3. HDMI Cable

Connect one end to: computer monitor, television

Connect other end to: HDMI port on computer (see image below)

Note: If you’re hooking up a television to your computer, then we would recommend that you use a HDMI cable as your PC cable connection since it is able to transmit both display and sound – So you can not only use your TV screen as a monitor, but also make use of your TV speakers to play PC audio.

4. PS/2 Cable

Connect one end to: PS/2 keyboard, PS/2 mouse

Connect other end to: PS/2 ports on computer (see image below)

  • Purple PS/2 port: keyboard
  • Green PS/2 port: mouse

5. Ethernet Cable

Also known as RJ-45 cable

Connect one end to: router, network switch

Connect other end to: Ethernet port on computer (see image below)

6. 3.5mm Audio Cable

Also known as phone connector (since 3.5mm jacks are often found on mobile phones too)

Connect one end to: computer speakers, 3.5mm headphones, 3.5mm microphone

Connect other end to: audio ports on computer (see image below use Green socket)

  • Green audio port: computer speakers or headphones
  • Pink audio port: microphone
  • Blue audio port: MP3 player, CD player, DVD player, turntable, electric guitar etc (line-in port to play and record sounds from the above devices)


USB Cable

For USB computer cable connections, there are two popular formats: USB 2.0 and the newer USB 3.0

How to tell USB 2.0 and 3.0 cables apart: USB 3.0 cables have a blue tip, and sometimes you can find a SS “Super Speed” label on it. 

Since USB was intended to be the one computer cable connection to replace them all, it’s no surprise that the possible uses for a USB port are quite mind-blowing. For this computer cable guide, we have listed its more common uses below:

Connect one end to: USB device

  • Storage devices: USB flash drive, external hard drive, external optical drive
  • Input devices: USB keyboard (wired and wireless), USB mouse (wired and wireless), webcam, scanner, gamepad
  • Output devices: printer, all-in-one office machine, USB speaker
  • Wireless adapters: network (Wi-Fi) adapter, bluetooth adapter, 3G adapter
  • Data (and charging) cable for mobile devices such as mobile phone, tablet, MP3 player

Connect other end to: USB ports on computer (see image below)

How to tell USB 2. 0 and 3.0 ports apart: USB 2.0 ports have black tips while USB 3.0 ports come with blue tips. See image below:

USB 3.0 is backwards-compatible… meaning that you can connect a USB 2.0 device to a USB 3.0 port and vice versa (but the USB 3.0 devices hooked up to a USB 2.0 port will perform at lowered rates)

There are also USB cables which connect new external backup drives (see below), these are described as USB-A to Micro-B

8. Computer Power Cord (Kettle Plug)

Connect one end to: AC power socket

Connect other end to: power supply unit (see image below), computer monitor

Note: Always turn off your power supply unit (with the 1-0 switch at the back) before connecting a power cord to it.

9. ThunderBolt/USB-C

Mostly seen on laptops and Apple Macs these cables are high speed and are capable of carrying Data, video and other information.

There are 2 current types of Thunderbolt, the older version Thunderbolt 2 is seen below but this can also be confused with Mini Display ports as they look identical and only visual difference is the picture beside the port. Thunderbolt 2 (left) has a lightning symbol and carries Data and video.

The Mini Display Port (right) will only carry Video.

And Thunderbolt 3 also known as USB-C on Apple Macs.

10. Display Port

Display Port is the best to use if you require a fast, high-resolution image.
The cable has better quality over HDMI and is the best option if you have this interface.

Best VGA Cable Reviews

1. Rankie VGA to VGA Cable

Linking your computer to your monitors from a 6-foot distance is easy with this Rankie cable. With a 15-pin VGA port, full HD resolutions on your movies are possible. Not only is this cord long enough to connect your media devices, but it also works for either LED or LCD monitors.

Rankie comes with a strain relief technology that prevents permanent bending of the entire cord. That way, the cables get relieved from stress. I like this feature because the conductors become less susceptible to breakage and possible malfunction.

Connection feels more secure because of its grip treads, which allow the users to plug and unplug without slipping their hands off. It also comes with a pair of finger-tightened screws to hold both ends firmly. So, there’s no way your VGA cables would slide off your media ports.

The connectors come gold-plated to reduce tarnishing. Plus, the conductors are of 100% bare copper. Copper is a universal atom vehicle, which allows free movements of electrons within the conductor. Therefore, signal transmission is efficient, and interruptions remain at the minimum level.

On the downside, some customers have experienced delayed shipping. This issue is not present in most reviews, though, so it’s not a huge problem.


  • 6-foot cable with full HD LED/LCD capacity
  • Comes with strain relief feature that fights permanent bending
  • Secured connection with grip handles and tightening screws
  • Has gold-plated connectors
  • Optimum conductivity with a full copper composition


  • Some customers experienced delayed shipping

I believe this cable meets the minimum requirements of a VGA cable for computer. It’s easy to manage and doesn’t mess up with the rest of my wires. Plus, I can say this is an affordable choice to make.

2. AmazonBasics VGA to VGA Cable

The AmazonBasics VGA to VGA PC Computer Monitor Cable offers a high-quality and reliable connection, whether at work or home. With a set of 15 VGA pins on both ends, video signals come out clear. So, even if you’re playing games or binge-watching, you can always be sure about optimum displays.

This product comes with a foil shield and dual ferrite cores to minimize radio and electromagnetic interference. That way, electron leakage is limited, and performance remains at a superior level, thanks to standard engineering that lowers the noise and disturbance of magnetic fields between conductors.

No matter the resolution you want, this cable will still show off. Supporting SVGA, XGA, UXGA, WUXGA, and Full HD resolutions, this AmazonBasics product will accommodate different output levels. I love this flexibility because my movies never have to go through rough moments before I could enjoy them.

One thing that makes me feel more comfortable about buying this product is its customer support after the receipt date. With its 3-meter VGA to VGA cord comes a 1-year warranty that assures its buyers of consistent performance and durability.

However, I found the tightening screws slightly difficult to use. They have no place to accommodate a screwdriver, only nubs, which are really hard to turn. Everything else works fine, though.


  • Optimum visual display, whether you’re playing games or binge-watching
  • Minimal radio and electromagnetic interference
  • Supports a wide array of resolutions
  • Comes with a 1-year warranty


  • Tightening screws are slightly difficult to use

This product works well with my office set-up. I get to conduct meetings and presentations without inconvenience. Its flexibility is also a definite plus for me.

3. Cable Matters VGA Cable

If you are into bare copper conductors with individual wire insulations, you can never go wrong with the Cable Matters VGA Cable with Ferrites. These insulators are vital in keeping single wires from making contact with each other. That way, my screens exhibit no mixed signals, and the frequency happens to be just at the right amount.

This cable comes wrapped in polyvinyl chloride for improved durability and protection. And because PVC has good resistance against abrasion, users prefer cables jacketed with this material. It also contains good tensile strength to fight against extreme bending.

Users might have to identify the output or input end with other products, but not with this one, as this VGA cord is bi-directional. That means I get to use either port as the receiving end or otherwise.

Routing your media through the sides of your room isn’t a problem at all. With a 25-foot length, you won’t have to worry about laptops messing up your views of the widescreen. All you need to do is to place your PCs on the side or anywhere that doesn’t cause viewing interruption, mount your cable, and you’re good to go.

What I feel needs improvement is the delivery package. My cables came in a padded envelope, which is flimsy, in my opinion. It would be better if the brand used something more sturdy.


  • Bare copper conductors
  • Comes with separate wire insulators to reduce noise
  • Wrapped in PVC for better durability and protection
  • Bi-directional cable that allows either port to be used as the input or output end
  • Lengthy enough to run along walls or corners


  • Delivery package should be more sturdy

This Cable Matters model is an ideal pick for users who make long-term entertainment room set-ups. I like it because it’s easy to use and maintain. Also, it saved me from moving my gadgets every time.

4. UGREEN HD15 Male to Male Cable

Quality is what the UGREEN HD15 Male to Male Video Coaxial Monitor Cable gives its customers. Through its 15-pin ports, you can experience a smooth movement of images and characters, whether in a video game or a movie. Avoid pixelated motion pictures with the help of this cord.

Signal transmission is secure because of its triple-layered shields that do not only guard its components but prevent leakage as well. These protections include PVC, foil, and braid shielding over the copper conductors. So, I feel confident every time I use my visual media devices since I know how reliable my cables are.

This cable also comes with ferrite cores to safeguard against EMI and RFI. These cores are resistant to high current, which allows low current losses on many frequencies. Thus, my devices are free from unwanted intrusion and possible malfunction.

No matter what your device is, know that this cable is compatible in almost all instances. So, even with TVs, monitors, computers, and projectors, you get the best of this PC VGA cable. This feature alone makes it worth my money.

On the downside, it takes a little effort to secure the screws. I don’t consider this to be a major drawback, though, because it still takes me little time to have the cable set up for use.


  • 15-pin ports on both ends for top-notch display
  • Triple-layered protection for a more reliable connection
  • Comes with ferrite cores to guard against interferences
  • Compatible with a wide array of devices


  • Screws are not easy to secure

All in all, UGREEN VGA cable is a good pick for many consumers. With it, I no longer have to worry about connection issues, plus I appreciate my investments in upgrading my entertainment gadgets.

5. Benfei Gold-Plated HDMI to VGA Cable

Coming with an anti-wear feature, the Benfei Gold-Plated HDMI to VGA Cable will keep your display on peak quality over a long time. This characteristic is essential for fighting deterioration caused by usage. Also, it helps your cable stabilize under operating conditions.

Benfei provides additional protection against oxidation. That way, your VGA cord doesn’t run out of electrons, and you get metal degradation resistance in all your conductors. What’s more, the brand provides an 18-month warranty, so you can reach out to customer service when there’s a problem.

Gold-plated connectors improve the stability of signal movements in my cable. This aspect helped me get out the best of my old VGA projector. I have never seen shaky and interrupted displays while using this cord. Also, it has a good grip on both ends, which is another plus.

Unlike other cables that leave you with no options when heating occurs, this product comes with a fast-heat dissipation solution to solve the problem. Thus, I don’t have to worry about overheating and the damages it can cause my devices.

However, I wish the product could also transmit audio since it comes with an HDMI input slot. In my case, I had to install a mini sound system to make my movie marathon a good one. Plus, I can’t interchange either end since the cable isn’t bi-directional.


  • Anti-wear feature that fights against deterioration
  • Resistance to oxidation
  • Comes with an 18-month warranty
  • Gold-plated connectors for optimum signal passage
  • Has good grip on both ends
  • Overrides heating through heat dissipation


  • Unable to transmit audio signals
  • Works on a single-direction operation only

Even though this product is imperfect in some aspects, the operation is still seamless. It’s not hard to use and maintain, and it doesn’t create any visual mess.

6. SHD VGA to VGA Monitor Cable

If your goal is to set up an entertainment system with convenience, let me recommend the SHD VGA to VGA HD15 Monitor Cable. This 3-foot VGA to VGA cable comes with what you need from installation to usage. What you have to do is to plug the male adapters into their respective ports and play.

This VGA cable for monitor ensures a high-quality run of images and motion because of its copper conductors. These pieces of metal come with an anti-oxidation feature. Therefore, the chances of disturbances during display are relatively low and are controllable.

Having a conventional gadget doesn’t have to be a problem for you. Knowing that some old computers cannot accommodate HDMI cables, this cord can be the best option for you. It works with devices like TVs, PSPs, PCs, and other LED and LCD monitors. So, having a laptop with only a VGA port is not an issue at all.

For a cable that’s currently being taken over by the rise of HDMIs, I am glad to know about the guarantee it has. It comes with a 1-year warranty to serve its customers even after the date of purchase. I felt some assurance buying this product since I don’t do well with troubleshooting electrical connections.

On the other hand, the cost to return this product is a little high, almost the same as the cost of the cable itself. It is something to keep in mind before purchasing.


  • Convenient installation and usage
  • Anti-oxidation copper conductors
  • Works with a wide array of devices, even with the old ones
  • Comes with a warranty of 1 year


  • The cost to return the product is a little high

With this cable, I can flash my games to big screens in an instant. It compliments my devices, and the quality is good enough for its price. I believe this will fit the needs of most gamers.

7. DTECH Monitor VGA Cable

The first thing that got me into the DTECH Ultra Thin Flat Type Computer Monitor VGA Cable is its thin wires. I find this 0.08-inch cable unique in terms of design. It fits almost everywhere, whether behind a cabinet or under a carpet. I also get to save space in my cable storage, and it’s easy to hide, unlike other rounded VGA cords.

Placing your devices at a distance is not a problem at all. With the cable’s operating distance of 8 meters, you will be able to connect your laptop to your projector, even if the latter is far away.

Made with gold-plated connectors and 100% bare copper conductors, this DTECH model possesses quality engineering. It comes with an RGB coax and 6-sync lines to ensure a complete layout of signals from the source to the monitor. Also, foil and copper shields help reduce interference.

This cable is also an affordable one on top of its commendable design, length, and internal build. Not only do I get to buy an extra long VGA cable, but I can see the value of my money as well. This aspect is one huge advantage for me as a college instructor.

I think it would have been better if the manufacturer had put these flat VGA cables through some quality inspections. The first pack I bought had some uneven spaces among the pins. I couldn’t plug one end in the port, so I returned it. The other packs I got were fine, though.


  • Thin cable that fits in all locations and helps to save space
  • Easy to hide
  • Lengthy VGA monitor cord at 25 feet
  • Quality engineering to ensure adequate signal transmission
  • Foil and copper shields to reduce interference
  • Affordable product fit for a classroom set-up


  • Some adapters contain awkward spacing among pins

DTECH gives me the convenience I need. This high quality VGA cable allows me to control my presentations from a distance. And it’s been working for more than a semester now.


C&E Standard Male to Male Cable

Designed to provide quality safety assurance, the C&E Standard 15-Pin VGA Male to VGA Male Cable will erase your worries about starting a fire at home or your office. This RoHS-compliant product comes with strain-relief connectors for enhanced durability. That way, the chances of tearing and open circuits are reduced.

Other than its reasonable price, I like this product because it responds quickly. I don’t have to wait for some idle time when I plug both ends into their ports. Efficiency wise, I believe this is a good pick for anyone.

This product comes with grip treads for easy plug-ins and out. Also, it comes with finger-tightened screws for a secure connection, no matter the set-up. These factors are beneficial to me, especially when I binge-watch with friends and my cables become susceptible to pulling and other motions.

Even with the conventional style of connecting computers to monitors, this cable doesn’t go behind high-end video amplifying cords. C&E supports many resolution levels for both LCD and LED devices. Say it’s old, but it works just fine.

I am worried about my videos dropping from full HD to a lower resolution. At first, I thought it was because of my internet connection, but I don’t think so since I have tried to play offline videos, but the same thing happened.


  • RoHS-certified with strain-relief connectors
  • Has a reasonable price
  • Short response time
  • Comes with grip treads and screws for a secure connection
  • Works with a wide array of video resolutions for LED and LCD devices


  • Some videos drop to a lower resolution

I believe this VGA video cable satisfies the need of most people who want to watch movies on big screens. The installation and usage are consistently efficient, and it comes at a reasonable price as well.

9. Benfei VGA to VGA Cable

Whether editing a video or doing a slide presentation, the Benfei VGA Cable with Ferrites assures you of quality performance. Getting into the smallest details in your motion pictures is possible because this cord supports top-tier LED and LCD resolutions. Be sure to get the best of your clips using this product.

Compatibility is a factor in a piece of equipment like this VGA to VGA connector. With this, Benfei ensures that no matter your device, as long as it has a VGA port, everything will work out fine. I like this feature, especially since I have different gadgets at home. I can make use of them freely and without worry about damaging them.

This cable is durable as well. It comes with tinned copper wires for protection against corrosion. And to guard against bending and potential cuts, this product has a flexible PVC jacket on the outside and layers of aluminum foil and braids inside. That way, I feel confident that my cord can endure rough handling.

One more benefit I have experienced with this cable is its guarantee. Unlike others that extend service support for around 1-3 years only, Benfei makes sure that their products stay longer and consistent by offering a lifetime warranty.

However, some of the screws are hard to mount. They can be annoying to use if you move the cable often. Nevertheless, the whole thing works well.


  • Detail-centered VGA display cable that supports top-tier resolutions
  • Compatible with all VGA devices
  • Durable cord made with quality materials
  • Manufacturer provides a lifetime warranty


  • Some screws are hard to mount

Thanks to this cable, I am happy about how my videos come out on the bigger screen. It fits all of my projects, and I feel like I’ve hit a reliable piece of equipment. I won’t hesitate to share this with my friends.

10. Cable Matters VGA Cable

Ideal for double-screen outputs, the Cable Matters 12 Inch VGA Splitter Cable will let you enjoy movies on one monitor with your family watching using another screen. This feature is possible through connecting one end to the source and the split VGA adapters to two viewing devices. These connectors are compatible with all VGA-port devices, making two more duplicates of your motion pictures.

One of my concerns before buying this product is the kind of display. Since I was using two monitors off the source, I thought I needed to compromise the quality. I plugged the adapters in, tried maximizing to full HD, and things worked out great. Plus, there were no downtimes during the show.

Reliability is a significant factor here because I get to involve several devices at once. This VGA cord comes with a heavy-duty splitter adapter to support the load of two output VGAs. Also, this cable is up for frequent usage, and it comes with a lifetime warranty. I am confident this product can withstand heavy use over a long time.

And while some users consider this pack of adapters costly, I believe this is just right for its grade. I get to maximize my display on both monitors, and I can play videos without hassle. I think the price is reasonable, and it gives me the value of my investment.

I was hoping to see an ‘extend’ feature in this HD VGA cable. All this time, I was dealing with duplicate screens with no chances of making a monitor extension.


  • Perfect for duplicate screen viewing
  • Supports full HD on both monitors
  • Reliable cable with a heavy-duty splitter adapter
  • Comes with a lifetime warranty
  • Reasonable price worthy of an investment


  • Does not come with a screen extension feature

This product made me skeptical at some point, but overall, this is a good one. I feel like this is a tailored fit for my needs. Apart from that, I can see it lasting longer than other cables.

11. DTECH 5 Feet Cable

The first thing I noticed with the DTECH 5 Feet Cable is its design. I love its all-black scheme because it looks clean and sleek. On top of that, I can see it is a durable cable with nickel-plated connectors, which are corrosion-resistant. And its outer covering looks sturdy and built for heavy usage.

This DTECH product comes with bare copper conductors for sufficient signal transmission. This kind of material fosters an ample number of free electrons necessary for data transfer. That means cables with copper conductors can maximize information from the source.

In addition, the manufacturer made this model with foil and braid shielding, which helps reduce noise and cross-talk. The result is a reliable connection that’s suitable for gaming, editing, and watching videos. Its support for Full HD resolution doesn’t hurt, either.

This cable comes with appropriate shielding to suppress electromagnetic and radio frequency interferences. That way, there’ll be no interruptions whenever you’re playing your favorite games or watching a series.

On the downside, I think this cable is a bit thick. Sometimes, it was hard for me to bend it to where I wanted it to go. It would be better if the cord were more flexible.


  • Clean black design with corrosion-resistant nickel connectors
  • Sturdy outer cover
  • Comes with copper conductors for sufficient signal transfer
  • Suppresses electromagnetic and radio frequency interferences
  • Foil-and-braid shielding to reduce noise and cross-talk
  • Supports full HD resolution, good for gaming, editing, and watching videos


  • Cord could be more flexible

Despite that, I believe this VGA cable fits just right for a video-amplifying setting. It looks sleek, easy to use, and I get the best visuals with this cable.

12. Benfei DisplayPort to VGA Cable

If you are having a hard time searching for the cable that would fit your gaming PC, the Benfei DisplayPort to VGA Cable is the best one for you. With a high FPS gameplay, you will experience quality graphics within your reach.

Working on different tasks became easy for me because this comes with an Extended Mode of display that helps me do multi-tasking, especially at work. That way, I don’t have to transfer tabs every time, and I can work on one monitor and open news on the other one.

Installation doesn’t require any software, but you need to secure your connections on both ends. This aspect is possible through the latches in the DisplayPort and the screws on the male VGA adapter. All you have to do is press the button on one end and rotate the screws on the VGA end when plugging the adapters in and out.

This cable also possesses top-grade durability. It has oxidation-resistant properties, heat dissipation, and wear protection. These factors prevent the deterioration of the cable’s components and promote the preservation of the entire cord. That way, I don’t only get to maintain my pieces of equipment, but I also add extra safety to my electronics.

However, I have experienced issues with the display port, as many customers did. After months of not removing the adapter, it failed to detach easily. I had to get some pliers and pressed the pins to get it out.


  • Perfect cable for gaming purposes
  • Features Extended Mode for a wider screen workstation
  • Installation requires no software
  • Latching tabs and screws for a secure connection
  • High durability for safety and preservation


  • Display port tends to get stuck when plugged in for a long time

Benfei DisplayPort is a reliable VGA monitor cable for me. I get the best comprehensive solutions to work and gaming. Plus, it’s durable and safe to use.

What to Look for When Buying VGA Cables

While it’s easy to decide whether or not you need a VGA cable, you should consider the following factors before buying one to give your video streaming an ideal upgrade.

There are two types of VGA cords, and they differ in terms of video resolutions. If you’re good with 640 x 480, pick the VGA. But if you want a higher resolution like 800 x 600, I would suggest choosing the SVGA.

Be sure to know the available ports you have on both your computers and monitors. You don’t want to buy a pair of male adaptors for a male-ported device.

Most cables come with VGA ports on both sides, but they might not be what you need. Some have VGA adapters on one side and an HDMI on the other end. Plus, other VGA cables can be mistakenly perceived as a DVI cable. Nevertheless, they are all available in the market.

Some devices prefer a specific brand in terms of accessories. So, always check for their compatibility with computers and projectors to pick the correct items.

Choose the one that can withstand bending and even stretching in some cases. Also, look for the ones made with quality materials, as specified on their boxes.

This aspect lies in the shielding of your conductors. The better the shielding, the less interruption to your motion display.

Always check for the warranty of the items you buy. You might exit the store happy about your cable working well but then it fails to perform the moment you reach home.

Is There a Difference in VGA Cables

VGA cords were present in almost all establishments before modern connectors came in. Today, these cables are still in use and are relevant enough to co-exist with other devices in the market. These accessories only differ in supported resolutions, gender, adapter combination, kinds of connectors and conductors, shielding, and materials used.

Is a VGA Cable Better than HDMI

The most salient distinguishing factor between a VGA and an HDMI cable is that the former can transmit video signals only while the latter can handle both video and audio. VGA cables were known universally in earlier years. HDMIs, later on, took over their share in the multimedia industry.

With VGA cords being less costly, people these days would still prefer HDMIs because they are light and can produce high definition digital audio-visual data. Also, note that VGA to HDMI and HDMI to VGA signal transmissions are possible, but the former will not improve output quality, and the latter can lower it.

Does It Matter What VGA Cable I Use

You have to remember that the cable you are using might not be what you need. The kind of VGA cable you should use is dependent on the following considerations.

The VGA you use should work in your setting. Whether at your home, office, entertainment room, or in other applications, the cord you pick must be compatible in all instances.

Some devices might be preferential in terms of cables they would accommodate. So, choose only the ones allowed by your device.

Some VGA cables can meet the bare minimum, but not all can go beyond it.


Giving your entertainment system a boost should not be a brainer at all. All you need to consider is your necessity, the VGA cable’s compatibility, and the quality of display you want to achieve.

Always check the figures and the range of usage before investing in this accessory. You might have seen the best VGA cable before you knew about the tips I have shared with you.

Top 5 Reasons To Get HDMI Cables For Your PC Monitor

Without a doubt, things were much simpler several years ago when the only thing you needed to connect the LCD monitor to the PC was the DVI system. Even though most computers available today support the VGA input – with a few exceptions such as the newest Apple TVs – in most cases, the modern PC monitors offered a better performance with DVI, the interface that was practically designed for all HDTV systems.

Nowadays, it appears that you can’t set foot into an electronic store without bumping into a salesman trying to convince you to buy the newest and naturally most expensive HDMI cable. While the shop assistants could get on your nerves, there are plenty of reasons why investing in a HDMI cable makes sense, especially if you want to use the computer in conjunction with the home theater system.

1. Video and audio in the same wire

The biggest advantage of HDMI over DVI consists in it being able to carry digital audio capabilities. Considering that the laptop includes at least three mini-jack ports to run the audio to the speakers, it’s clear that by using HDMI you are reducing the number of cables required to carry the audio signal to the monitor. The same is applicable for desktop computers since with a single cable you can ensure to run the audio signal from the sound card to the graphic card and turn it into a single digital stream.


The high definition copy protection signal

Because DVI doesn’t require HDCP, monitors and computers integrating this connection are practically locked from high definition content. Even though over the years some manufacturers designed video cards with HDCP signal, there wasn’t any guarantee that the rest of the hardware is compliant. The HDMI had the HDCP signal built into it from the start and therefore, you can be sure not to experience issues with non-functional or restricted digital content in the future.

3. Compatibility

In the event that you are trying to connect a HDMI cable to a DVI monitor, your job is pretty much straightforward, providing you have an adapter cable. Therefore, if you’re considering upgrading your home computer gradually and purchasing HDMI compatible hardware, you will get to enjoy the full array of benefits proprietary to the technology.

4. Amazing color depth

The old computers were limited by the 24-bit color system and back then, it was believed that over 16 million colors are more than enough since the human eye is incapable of distinguishing between very similar shades. While the early HDMI adhered to this principle, the newer versions can support up to 48-bit color depths and double the shades, an element that is most visible on high resolution screens. The only catch is that the monitor and the graphic adapter must both support HDMI 1.3 or newer.

5. Smaller connectors

The DVI connectors are similar in size to the old VGA one, namely a rough 1.5 inches width. On the other hand, the HDMI features connectors three times smaller than that. Furthermore, the newest HDMI versions come with mini-connectors that are even smaller and consequentially, perfect for camcorders and notebooks.

What & How They Work?

If you are a computer geek or a lover of the computer world then it is essential to know of the thing that connects some significant components of the computer, i.e., different computer monitor cable types and their connectors.

Whether you desire to set up a new PC or intend to upgrade to a second monitor, the essential things to have the best experience are the computer components.

Having a good knowledge of the computer cables will help you avoid the confusion in choosing the best one.

You now need not be in a foreign jargon while looking at the computer equipment.

Here you will find an exciting overview of the computer monitor cable types that you will have to encounter when using the computers.

In this technological era, it is quite essential for you to have a good knowledge of computers.

While using desktop computers, you will have to work with the cables too to attach different devices.

Following are some essential cable types that you will have to use while working with computers:

  1. VGA
  2. USB Cable
  3. HDMI Connector
  4. HD 15 Monitor Cable
  5. DVI cable
  6. IDE

What is the Definition of Cable?

These are the insulated wire that transmits the electricity.

There is a plastic covering around the cables.

Types of Computer Cable

Two main types are:

1) Data Cables

It provides a mean of communication between various computer components.

Some popular ones include

2)  Computer Power Cable

It provides power to the device

Computer Monitor Cable Types

The most common ones are:

1) VGA Cable

VGA stands for video graphics array.

  • They were introduced in 1987 by IBM.
  • It transfers the video signals.
  • It carries the electronic signals from one hardware device to another.
  • Its function is to connect an analog PC monitor to a laptop or a PC. It uses an HD15 connector to connect the monitor to the PC
  • Pins are present on the inside of the plug. These pins fit into the hole pattern that is present on the backside of the computer.

To identify them you can look at the pins inside the plug. VGA cables have mostly 14 pins on the inside.

  • All PCs have VGA installed in them.
  • Thet gave the capability of displaying the video even without installing the drivers,
VGA vs.

SVGA Cable

VGA is the Video Graphic array while SVG stands for Super Video Graphics Array

Video Resolution

VGA supports video resolution up to 640 x 480 while SVGA can have a resolution of 800 x 600

Thickness and Shielding

SVGA has more shielding than the VGA cables. This shielding is the reason that they are a bit thicker than the VGA.


SVGA cables perform well for long distances.

For devices that are much closer to each other, you will most probably need the VGA cable. In such cases, buying an SVGA cable will be a wastage of money.

2) USB Cables

USB stands for the universal serial bus. It is now widely used in the computer peripherals.

USB is primarily an industry that came up with a goal to standardize the computer peripheral for the computer connection.

Many computer components in modern times have some form of USB cables and connections.

  • Their primary use is to connect the computer to the camera, mobile phones and other device of this sort.
  • You can also use it to connect the computer to any secondary display device.
  • Well, it is better not to use it to connect to the monitor. The reason is that the USB cables have a limited resolution, i.e., 1024 x 768.
  • These cables work for replacement screens for laptops.
Types of USB Cable Connector


You might be thinking that by name its universal then how its three types came?

Well, there are different types because each of these types offers different functionality. They all perform various functions.

Some of these types are:

  • USB 2.0 Type-A
  • USB 2.0 Type B
  • Mini USB 2.0 type B
  • Micro USB  2.0 Type A
  • USB 3.0 Type A
  • USB3.0 Type B
  • Micro USB 3.0
a) USB 2.0 Type-A
  • It is also known as the USB standard connector.
  • It was introduced in the 90s.
  • It works on the computer’s host controller.
  • Its function is to provide a downstream connection.
  • It also protects the incorrect connection, i.e., you cant plug it upside down.

Its size is a bit greater, and that’s why it is not much suitable for portable devices.

b) USB 2.0 Type B
  • They are not much popular.
  • The modifications are either square-shaped or trapezoidal shaped.
  • They have a bit larger size that why they are mostly used in many peripherals and stationary devices like printers and scanners.
c) Mini USB 2.0 type B
  • It is used widely in portable devices like card readers and iPod
  • It is a bit less prevalent at present because of the micro USB.
d) Micro USB  2.0 Type A
  • This one is the modified version of the one described above. i.e., the mini USB type A.
  • In 2011, this connector was approved as the single standard for charging the portable devices.
  • Modern smartphones have this connector.
What is USB 3.0?
  • It is much faster than the older versions
  • It provides higher data transfer rate.
  • It can receive and transmit much higher power than the earlier versions.
e) USB 3.0 Type A
  • This one has the capability of providing a much higher data transfer rate as compared to the earlier versions.
  • You can still use USB3.0 Type A with the USB 2.0 plugs without experiencing any speed loss or any other thing of this sort.
  • Thus they are compatible with the earlier version too.
  • Modern laptops have this connector.
f) USB 3.0 Type B
  • Modern laptops have this connector.
  • This one is a bit different from the type B of the earlier version, and that’s why it cant be used in USB2.0 type B plugs.
  • It works well with higher performance devices.
g) Micro USB 3.0
  • It provides much higher data rate as compared to the earlier version micro USB, i.e., micro USB 2.0.
  • You can use old concestor of this type in the new plugs but not the new ones in the old plugs.
Micro VS Mini USB

Many people have confusion between these two connectors.

The first one is larger in dimension than another one.

3) HD 15 Monitor Cable

HD 15 is the most commonly used one.

  • This cable is referred to as the standard VGA cable.
  • It is mostly blue.
  • Its responsibility is to communicate the image data.
  • It is a universal connector that you can use as the video interface for PCs.
  • HD displays, satellite receivers, and cable boxes also use it.
  • The HD15 connector has 15 pins in a row.
  • Each row consists of 5 pins.
  • It is also called HD DB15. This is because it is a high-density D style connector.

It’s one drawback is the limitation of resolution features. It supports the resolution of 640×480. This resolution value is the reason it can’t be used in the new devices and gadgets that need high resolution.

4) DVI Cable

Full form of DVI is Digital Video Interface. It is one of the most common technologies for the video display across LCD monitors.

  • This one provides a complete solution as it can communicate digital and analog data.
  • Modern devices use this type of cable to connect to the digital monitor.
  • It also can reduce the digital noise in LCD.
DVI Resolution

It can support the following resolutions:

  • 2560 x 1600 video resolution
  • 1920 x 1200 image resolution

You might think that it resembles the VGA cables.

Well at first glance it might look similar to the VGA cable, but in reality, it isn’t.

The difference is that it has longer flat pins as compared to VGA.

DVI Length
  • The maximum length is not an exact value. The reason is that the manufacturers are trying their best to provide the best quality output and for this, they go for stronger cables.
  • The minimum length that they should maintain is 5 meter approx.
  • One more thing that you should note is that if you use DVI-I cables of extended length, then you will not be able to see an excellent quality display.
Types of DVI Monitor Cable Connectors

It has the following categories:

  • DVI-D-True Digital Video
  • DVI-A- High Res. Analog
  • DVI-I – Integrated
a) DVI-D-True Digital Video
  • It has three rows. Each row with eight pins.
  • To connect a DVI computer to another DVI monitor, you will need a DVI-D cable.
  • Their primary task is to provide a faster and higher quality digital connection between the video source and the monitor.
How DVI-D Works?
  1. First, a digital video signal is reduced by the video card.
  2. Then this digital video signal is converted into the analog at the VGA output.
  3. Then this signal (that is now the analog signal) is converted again into the digital signal when it goes to the monitor.

Thus DVI-D works in eliminating this analog conversion process and provides a higher quality connection in between the two devices (the source and the display).

b) DVI-A- High Res.


  • It consists of 17 pins and carries the analog signals.
  • If you intend to connect a DVI monitor to a VGA monitor, then you will need this type of cable.
  • They carry the DVI signal to the analog display.
  • They are mostly used in connecting to the device with the VGA connector.
c) DVI-I – Integrated

They are the integrated cables that can transfer the following:

  1. A digital to a digital signal
  2. An analog to an analog signal

5) HDMI Cable

  • HDMI stands for High Definition Multimedia Interface. Modern computers now have the HDMI port.
  • It consists of 4 shielded twisted pairs
  • You will find this cable in many home theatre and LCD televisions.
  • It is an interface that transmits uncompressed and decompressed audio and video data to a monitor or any projector.
  • It has many versions.
HDMI Cables Feature Explained

It has replaced the analog solutions that required separate cables for radio and video.

Some feature that its newer version include are:

  • 3D
  • CEC Extensions
  • Ethernet Data Connection
How to Increase the Distance Between HDMI Signals?

Following are some of the ways in which you can do so:

  1. Use HDMI operators
  2. DMI switches
  3. HDBaseT Technology

  3. From the multiple display settings option, you can control how you want the display to be.
  4. You can also change the resolution.

If you are unable to see the second monitor in the options, then you need to do troubleshooting.

You might be thinking if your computer monitor screen has scratches then will you be able to see a brighter display on the second monitor?


Well, the answer is yes, you can surely enjoy a brighter display on the second monitor in this regard, but if there is an issue with any video hardware, then the display might not be as per your desire.

Which Cable to Use Among Different Monitor Cable Types? – A Tough Decision


After reading about all the types of DVI cables, you must be thinking about which one to use?

Am I right?

Well, it is a bit critical situation too, but you don’t need to be confused in this regard.

The first thing you need to do is to check the female DVI plugs and see their compatibility signals.

  • You will need a DVI-D cable if you see both the connector or any one of them as a DVI-D cable.
  • If both or any of them are DVI-A, then you will need a DVI-A cable.
  • You will need a DVI to VGA cable if one connector is DVI and the other one is the VGA.
  • And last but the most important one. If one is analog and the other one is digital, then you can’t connect the two with anyone cable.
  • For this connection, you will need a converter box.

Final Words

Thus different computer monitor cables help you enjoy the best display on your screens.

Monitor cable connector types are also explained above in this article so that you can have full knowledge in this regard.

Types of Monitor Ports – HDMI, VGA, DVI, USB Type-C, AV, NDI, SDI

Xenarc Technologies offers the best in industry truly rugged LCD Monitor and Touch Screen Display solutions that are designed and built to last.  We have solutions meeting mission critical requirements such as water and dust environmental protection, water resistant for disinfection, high brightness sunlight readability, shock / vibration / impact resistant, and extreme cold and hot operating temperatures.  Before picking the right ruggedized Industrial Monitor or Industrial Touchscreen for your application, let’s understand the different types of Display Interfaces.

Here’s a quick summary of the Video Input Connector Types:

  • HDMI: Audio and video signal, best for TV to PC connections.  
  • DVI: Video only, perfect for older systems or for 144Hz at 1080p.
  • DisplayPort (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K.
  • VGA: Old, legacy video connector. Only to be used when nothing else available.
  • USB-C: Formally known as USB Type-C.  Connects to both hosts and devices, replacing various electrical connectors including USB-B and USB-A, HDMI, DisplayPort and 3.5mm audio cables and connectors.
  • Thunderbolt: A hardware interface developed by Intel (in collaboration with Apple) that allows the connection of external peripherals and monitors to a computer.  Thunderbolt 1 and 2 use the same connector as Mini DisplayPort, and Thunderbolt 3 uses the USB-C connector from USB.
  • AV (RCA)AV input is a common label on a  RCA type connector to receive analog (AV) Audio / Visual (CVBS composite video) signals from electronic equipment that generates AV signals (AV output).
  • NDINetwork Device Interface – Format that allows you to send audio and video via ethernet network
  • SDI:  SDI Serial Digital Interface is a professional video signal that is preferred in production environments because of its longer range (up to 300 feet) and reliability, since it’s typically sent along BNC Cabling that has specialized connectors on each end to lock into the devices they connect to.

Previously, only an analog VGA interface was utilized to connect a rugged LCD monitor to the computer. With the development of new technologies for flat-panel monitors, the capabilities of the VGA connector have become insufficient. To attain the highest image quality, you need to use a digital standard, such as DVI. Manufacturers of devices for home entertainment have created the HDMI standard, which became the digital successor of the analog scan connector. Somewhat later, VESA (Video Electronics Standards Association) designed DisplayPort. As mentioned earlier, modern devices are equipped with various monitor ports: HDMI, DVI, VGA, DisplayPort (DP), USB-C, Thunderbolt, SDI. Let’s consider each of the interfaces.

Common, but old.

Monitor with VGA port.

The then-leading IBM computer manufacturer developed the first connection standard, used today too, in 1987 for its PS / 2 series PCs. The blue trapezoidal interface worked perfectly with old CRT displays, thanks to its analog nature. But then flat LCD digital screens appeared, resolutions began to grow, and the time-honored VGA port started to give up ground. Today, it is more rarely integrated, but until now, an array of devices such as home players, projectors, TVs, etc. are still equipped with VGA ports. Probably, for several more years more, it will remain not as desirable, but still the ubiquitous standard.

Monitor with DVI port.

This abbreviation stands for Digital Visual Interface. It transmits a video signal in digital format while maintaining high image quality. In the mid-2000’s, DVI replaced the rapidly outdated VGA. The ability to transmit both analog and digital signals, support for large (in that era) resolutions and high frequencies, and the lack of inexpensive competitors led to DVI becoming a standard port for today. Low-cost video cards are equipped with the Single Link DVI. The maximum resolution, in this case, is 1920×1080 pixels – Full HD. More expensive video card models have a Dual Link DVI interface. They can be connected to monitors with a resolution of up to 2560×1600 pixels.



Modern types.

Monitor with HDMI port – the king of multimedia. 

HDMI stands for High Definition Multimedia Interface. In modern home entertainment devices, such as flat-panel TVs and Blu-ray players, HDMI is the standard connection interface. As in the case of DVI, the signal is transmitted in digital format, which means maintaining the original quality. Together with HDMI, HDCP (High Bandwidth Digital Content Protection) technology was developed to prevent the piracy and illegal copying of video materials. The first devices with HDMI support appeared in late 2003. Since then, the standard has been changed several times; in particular, support of new audio and video formats has been added. Precisely why did HDMI become so popular?

• Length of cabling up to 25-30 meters;

• Sound transmission (even multi-channel) together with video – no need for separate speakers;

• Convenient small connectors;

• Support for many different devices: players, TVs, projectors, DVRs, game consoles, etc.;

• Ultrahigh resolutions;

• 3D-picture; possible together with ultra-high resolutions (versions of HDMI 4b and 2.0).

The prospects for HDMI are the most promising – development keeps moving. In 2013, the specifications of version 2.0 were adopted; this standard is compatible with old wire connectors, but it supports resolutions that are more impressive and other excellent features.

Monitor with Display Port – only becomes ubiquitous. 

For many years, computers were rarely equipped with this competitor of HDMI this in spite of the fact that DisplayPort has many strengths:

• Support for very high resolutions along with stereo signal;

• Audio transmission;

• Impressive length of cabling

This interface technology is even more profitable for manufacturers than the licensed HDMI: they do not need to pay the developers the 15-25 cents that would be necessary for users of HDMI. Although in its first years of existence this type of connector was not particularly popular, now computers are more often equipped with a pair of Display Ports.

Monitor with USB port.

The connection with the help of USB connector became possible when version 3. 0 appeared. Using the DisplayLink adapter, you can connect a monitor with a DVI / HDMI connector to the USB port of your laptop or computer. Such ports are the standard for connecting external devices, which all manufacturers of these devices are eager for. USB ports connect mice, keyboards, printers, scanners, modems, card readers, flash drives, cameras, cell phones, players, hard drives, optical drives, etc. This connector is needed for those who plan to work simultaneously with multiple monitors.

In conclusion.

Having become acquainted with all types of ports, now you understand what exactly you need. Regardless of what suits your requirements best, you can find 7″, 8″, 9″, 10″, 12″, 15″, 18″, 24″ rugged LCD touchscreen monitors with any ports you need among the range of products at Xenarc Technologies.  Xenarc Technologies also manufactures IP67 Waterproof Video Connector Cables that works with our IP67 montiors, providing waterproof protection.  We can also custom design and manufacture a monitor with and without touchscreen, customized the cabling, and custom add or remove technology to fit your industry requirements.







Which Monitor Cable Do You Need?

With all the cables standards available, choosing which cable to use can seem a daunting task, especially if you aren’t much familiar with the various types and their features. But don’t worry! Our in-depth review will definitely help and make the choice for you!

  5. FAQ


VGA (Video
Graphics Connector) is a three-row 15 pin connector. Often accompanied by a
pair of thumbscrews, the VGA cable was introduced in the 1980s and soon became
the preferred standard – Whether it be bulky computers, laptops, projectors, or
video cards, you would always find a VGA port.

What Resolution Does
VGA Cable Support?

 While the VGA connector is capable of
supporting a resolution of 2048x1536p at 85Hz, the signal quality decreases
over 1920x1080p owing to the signal’s analog nature, resulting in a drop in
image quality. As newer and more efficient cable standards were introduced, the
use of VGA cable decreased, and nowadays, you may not find a VGA port on every
modern-day display.

What is The Recommended
Cable Length For VGA?

Cable length
does matter when buying an HDMI cable because longer cable lengths can result
in a decrease in signal quality.

VGA cables
can work well up to 50 feet (15 meters).


in the 1990s, the DVI (Digital Visual Interface) is a cable standard consisting
of three types:

  • DVI-A
    (Analog Only)
  • DVI-D
    (Digital Only)
  • DVI-I  (Digital and Analog)

Despite the shift to better cable standards, DVI-I and DVI-D are still commonly used and supported by graphic cards and displays, especially the budget-friendly monitors. The DVI-A cable, however, is hardly used nowadays.

What Resolution Do DVI
Cables Support?

DVI cables
are either single-link or dual-link. The single-link DVI-I and DVI-D cables
support a resolution of 1920x1200p at 60Hz, whereas the dual-link versions of
DVI can run QHD (2560x1440p) resolution at 60Hz. Though, do remember that DVI
cables do not possess audio support.

What is The Recommended
Cable Length For DVI?

recommended length for DVI cables is 5 meters, 
especially if you want to run a 2560 x 1440p resolution.


HDMI is a
relatively newer technology and has become one of the de-facto cable standards,
with the majority of modern-day displays and GPU being equipped with an HDMI
port. HDMI consists of:

What Resolutions Do The
HDMI Types Support?

HDMI 1.4 supports: 1920 x 1080p (FHD) at
120Hz, 2560 x 1440p (QHD) at 60Hz and 3840 x 2160p (4K) at 30Hz

HDMI 2.0 supports: 1920 x 1080p (FHD) at
240Hz, 2560 x 1440p (QHD) at 144Hz and 3840 x 2160p (4K) at 60Hz

HDMI 2. 1 is the most recent and advanced
version of the HDMI standard and supports 3840 x 2160p (4K) at 60Hz and 7680 ×
4320 (8K) at 30Hz

Which Cable Do You Need
For Xbox?

Xbox One X: It requires an HDMI 2.0 to run 4K at

Xbox One S: You will need an HDMI 2.0 to run 4K
at 60Hz.

Which Cable Do You Need
For PlayStation?

PS4 Pro:  It requires HDMI 2.0 to run 4K at 60Hz.You can
also use an HDMI 1.4 cable, but it will be restricted to displaying 4K at 30Hz.

PS4 and PS4 Slim:  An HDMI 1.4 cable will work just fine.

What is The Recommended Cable Length

recommended cable length for an HDMI cable is about 25 feet (7.6 meters),
though there are also boosted HDMI cables, which can exceed 50 feet in length.

If you wish
to utilize HDMI cable for 4K, the recommended length is 10 feet (3 meters).


HDMI, DisplayPort is one of the leading cable standards. Over the years,
different versions of DisplayPort have been released:

  • DisplayPort
  • DisplayPort
  • Mini-DisplayPort

What Resolutions Do The
DisplayPort Versions Support?

DisplayPort 1.2 supports: 5K resolution at 30Hz, 4K resolution at
75Hz, and 1080p resolution at 240Hz

DisplayPort 1.4 supports: 5K resolution at 60Hz, 4K resolution
at 120Hz, and 8K resolution at 30Hz.

1.4 also supports DSC (Display Stream Compression), making it capable of
running 8K at 60Hz.

Mini-DisplayPort is capable of delivering equal
bandwidth as its DisplayPort version. This means that mDP 1.2 supports the same
resolution as supported by DP 1.2.

What is The Recommended
Cable Length For DisplayPort?

cable runs well with lengths under 50 feet (15 meters).


DVI vs VGA: Which One
Is Better?

DVI cable is
better as it is a newer technology than VGA and carries digital signals
compared to VGA’s analog, resulting in better overall image quality.


HDMI vs DisplayPort:
Which One Is Better?

As far as
Image Quality is concerned, there isn’t much to separate the two standards.
With the release of newer versions, both HDMI and DisplayPort have increased in
their bandwidth and the resolution they support. It is checking the version of
the cable, rather than the standard, which you want to use. For example, DisplayPort
1.4 is better than HDMI 2.0 for 4K as DP1.4 supports 4K resolution at 120Hz
whereas HDMI 2.0 supports it at 60Hz.

thing to consider is the VRR technologies supported. HDMI only supports AMD
FreeSync, whereas DisplayPort supports AMD FreeSync as well as NVIDIA G-Sync.
So if you have an NVIDIA GPU, DisplayPort will prove a better choice.

also comes with MST (Multi-Stream Transport), which enables you to connect multiple
displays using a single cable. HDMI does not have MST support, making
DisplayPort a better choice for professionals.

While both
HDMI and DisplayPort are widely-used standards, HDMI, unlike DisplayPort, is
also the preferred standard for televisions, projectors, and gaming consoles.

both DisplayPort and HDMI are almost equally good standards and you should
choose the standard which will enable you to utilize the features you want.

Why is there no image on the TV from the computer (laptop) through the HDMI cable

In some cases, after connecting the TV to a computer or laptop via an HDMI cable, the image simply does not appear on the TV. Rarely, but it also happens that there is sound via HDMI, but there is no picture on the TV. Although, it seems to me that most often they are faced with the opposite problem when there is an image, but there is no sound via HDMI.

In this article, we will try to deal exclusively with the problem of image output via HDMI cable.It seems that everything is simple there, we connected the TV to the computer, selected the required input on the TV, and if necessary, then on the computer we also select the required image output mode. And according to the idea, everything should already work. And instead we see the inscription “No signal” on the TV.

Before moving on to any tips, check out the instructions for connecting your TV to your computer via HDMI:

If you do everything according to the instructions, but there is no result, and the image on the TV has not appeared, then now we will figure it out.

There is no signal on the TV via HDMI and there is no picture

First of all, you need to check cable connection , and remember the HDMI input number on the TV to which the cable is connected. Check if the cable is well plugged into the outlet on a laptop or desktop computer. Then, check the cable connection on the TV, and be sure to check which HDMI input you connected the cable to. They are signed. It looks like this:

For example, I connected the cable to the HDMI input under number 3.The fact is that the TV most likely has several inputs. And in the settings we will need to select the one to which we connected the cable.

Checking the settings on the TV. We select the appropriate HDMI input in the settings. Not always, after connecting the cable, an image from the computer appears on the TV immediately. Most likely, you will see the inscription “No signal”, or “Cable not connected”. There should be a button on the remote control from your TV that opens a menu with a choice of signal sources.On Philips TVs, for example, this button is labeled SOURCES . Click on it, and select the HDMI input with the desired number from the list.

On LG TVs – INPUT button. Click on it and select the required source. On the new LG TVs on Web OS, it may have already done something differently. But the scheme is always the same on any TV (Samsung, SONY, LG): open the menu with the choice of the signal source and select the HDMI input with the desired number (to which the cable is connected).

We check the settings on the computer. The computer may have turned off the output of the image to the projector (TV, monitor), so the picture does not appear on the TV and there is no signal. It’s very easy to check. In Windows 10, Windows 8 and Windows 10, just press the key combination Win + P , and select one of the three options for displaying the image: Duplicate, Extend, Projector only.

If you have selected “Disconnect projector”, then HDMI image will not be output.In Windows 10, everything is about the same, only there a menu on the side of the screen appears.

If you still could not make friends with the computer with the TV, then it would be good to find out what the reason is: in the TV, in the computer, or in the cable. This is not difficult to do. Especially if you have another PC, TV, monitor with HDMI input, or another cable.

Try connecting your laptop to, for example, another TV or monitor. If everything works, then the problem is with your TV (which is unlikely).This will eliminate cable problems. Also, you can just take another laptop (even borrow from a neighbor) and connect it to a TV that does not display an image. If everything works, then the problem is in your laptop (computer). Which is most often the case.

One more tip. Try updating the video card driver with your HDMI-connected TV. Just download the driver from the laptop / graphics card manufacturer’s website and install it.

Update: Andrey shared one interesting solution in the comments.After connecting the TV to the laptop, the TV had a “No Signal” error. But the laptop saw two monitors (built-in and TV). Changing the frequency for the second screen (TV) helped. I decided to add this solution to the article, and show in more detail how to do it.

Windows 10

Open the screen parameters and see that there are two displays.

Scroll down the settings page and open “Additional display parameters”.

We look closely.There will be “Display 1” and “Display 2”. Near one of them may be the name of your TV. I now have one display inactive, since the image is displayed only on the second display. Click on “Display adapter properties …” . You need to open the properties of the TV.

In a new window, on the “Monitor” tab in the “Screen refresh rate” menu, set 60 Hz. Click “Apply”.

After that, the error “No signal” on the TV should disappear.An image from a computer connected via HDMI appears. For some reason, Andrey’s system set the TV frequency to 25 Hz.

Windows 7

Right-click on an empty area of ​​the desktop and open “Screen Resolution”. The TV must be selected in the “Screen” menu. Let me remind you that this method can be used only when Windows sees a TV connected via HDMI, but does not display an image.

Go to Advanced Options and on the Monitor tab select 60Hz.Apply the settings.

If this method worked, write about it in the comments.

Update: Disconnect all unnecessary items from the TV. For example, an AV cable (tulip). Another device that can also be connected via HDMI. There is information in the comments that unplugging the hard drive from the USB port helped!

Update: if you have an LG TV (this may apply to other TVs as well), then disable the “Quick Start” and “SIMPLINK” function in the settings.

There are reviews that this helped.

Update: in the comments Roman suggested that disabling the HDMI ULTRA HD Deep Color function in the LG TV settings helped him.

Later, Oleg confirmed that HDMI ULTRA HD Deep Color really solves the problem with the image output via HDMI to the LG TV, but it is not advisable to disable this function, as it spoils the image and distorts it. And I shared my solution. It is necessary to change some parameters for the second display (TV) in the settings of the “Nvidia Control Panel” application, the icon of which is usually displayed in the tray.

If you have AMD graphics, the application is called AMD Catalyst Control Center. There should also be similar settings.

Update: Unplug the TV for a few minutes. In the comments, they suggested that in this way they managed to solve the problem with the absence of an image via HDMI (there was just a blue screen on the TV).

What should I do if my computer does not output an image via HDMI to the TV?

When we determined that the problem is in the computer or laptop.

The video card displays the image, and we actually connect to it. This means that the problem may be in her. Yes, it is possible that something burned out there, etc. But as a rule, it is a software problem. Something with the video card driver, or with the settings, so the image via HDMI does not go.

Therefore, the first thing to is to update the driver for the video adapter. It is important! If you have a laptop, then go to the manufacturer’s official website, find your model through the search, select the operating system that you have installed, and download the VGA driver.Then, run the installation.

If your laptop has two video adapters, update the drivers for both. Maybe for example nVidia Graphics Driver and Intel Graphics Driver like on my ASUS laptop. You can install the Intel Driver & Support Assistant to update the Intel Graphics Driver.

And if you have a stationary computer, then download the driver from the video card manufacturer’s website. Which video card is installed, you can see in the device manager, or in the characteristics of the system unit.

If you somehow managed to solve the problem with the image output to the TV using an HDMI cable in a different way, then share your advice in the comments. I will be grateful.

How to choose an HDMI cable to connect a TV, laptop and other devices

Home → How to choose and connect HDMI cable

rapid development of IT technologies, a large number of people want to be
knowledgeable about the intricacies of choosing an HDMI cable.Among
such a variety of products on the market, inexperienced users
easily get confused. And so let’s look at the nuances of acquiring a cord with
the desired interface.

HDMI has long been present in everyday life, although this circumstance is still not
adds competence to some people. And in order to dispel the doubts of buyers,
Note that HDMI has a smaller footprint than DVI. Also in
unlike the once popular video interface, it is equipped with protection,
preventing data from being copied.

type is used in the communication of the following devices:

  • Connecting a PC, laptop, tablet to TV, computer
    monitor, projector.
  • Connecting DVD player to TV.
  • Post game consoles,
    Blu-ray and other components.

HDMI cable length

the maximum length of the cord was limited to only 10 meters – when exceeding
of this distance, the appearance of artifacts or complete attenuation was possible
signal.The solution was to use extension cords and repeaters when
transferring content over tens of meters.

Even now
there is misinformation among consumers – some people believe that
10-meter wire supposedly represents the top of the possibilities for high-quality
transmission of information without amplifiers. Now you can stream video without
using any amplifiers up to 40 meters. Moreover, a cable up to 25 meters quietly transmits a signal without amplification.And on cables with a length of 30 and 40 meters is built-in
loss compensator.
Which not only amplifies the digital signal to such a large
distance, but also transmits it with a resolution of pictures up to 4096p (4Kx2K).

For devices working at a long distance

similar products are equipped with a distortion compensator. Therefore, technology
allowed to exchange films over such considerable distances without involving
devices that amplify the signal.

stores are ready to offer cords of greater length to the interested audience.
So, users’ desires can be satisfied with 60-meter HDMI
cords. Nevertheless, for a similar length, it is better to use extension cords along
twisted pair. Which will help you connect equipment
located at a distance from each other from 40 meters and up to 150 meters without
cascading. If you need a distance of more than 150 meters, then with
using the cascade system of some extension cords, you can run the signal up to
300 meters!

Versions of HDMI cables

in this article, the interface was the fruit of the work of several popular players
market, including Philips and Sony.The first version of the cable was
released in 2002 and until now the product does not give up its positions among
a great assortment of computer devices. Obviously what’s going on
Continuous improvement of the HDMI standard, confirmed with the release of a new

After undergoing
a series of updates, the interface in question was released in 2.0 format. This version
replaced 1.4, which will soon be 10 years old since its release, and
is designed to improve the quality of the transmitted video.Although HDMI
the previous version also works with 4K Ultra HD mode, it lacks the necessary
bandwidth. After all, a fourfold excess of the Full HD 1080p format is not
capable of functioning normally at 10.2 GB / s.

Advantage of Specification 2.0

HDMI 1.4 is rated for a maximum resolution of 3840×2160 (4K) with
using frequencies such as 24, 25 and 30 hertz. Also available
reproduction of content with picture sizes of 4096×2160 and frequency of 24
hertz, which corresponds to a full fourfold increase
of the aforementioned Full HD.

less, such characteristics cannot make the outdated version 1.4 good
choice for watching videos with frequently changing frames like dynamic
toys, action movies filled with special effects, or sports broadcasts
competitions. Today, using 2160p24 / 2160p30, you can only
while away the time on long-running television series, in particular

Increased throughput and beyond

new generation standard 2.0 supports Ultra HD 4K, but it has
the capacity has already grown to 18 Gb / s.

This technology contains the following
innovative solutions:

  • Increase in the number of
    audio channels up to 32 (4 times more than in version 1.4).
  • Maximum audible frequency
    tracks 1536 kHz.
  • Parallel transmission
    information to 2 devices using 1 display.
  • Audio can now be sent
    through 4 channels for different people.
  • Introduced compatibility with
    aspect ratio 21: 9.
  • Picture and Sound Now
    synchronized dynamically.
  • Supplement for communication with
    remote controllers (CEC).
  • The color depth is 10 –
    12 bit when watching movies in Ultra HD.

HDMI cable types

versions inherent in HDMI, can disorient the average user.Now
there are five types of specifications, the most recent of which is released on
the end of 2017. Additional confusion arises from the fact that although different
specifications are interchangeable, types of connectors are different. When 12 years ago the world
saw version 1.3, all the specifications of the discussed interface were divided into 2
categories – standard and high speed.

in addition to these two categories, all HDMI cable models are divided into four types, because
they all have a different purpose in operation.Incorrectly selected view
cable is capable of causing serious distortion to the resulting picture.
Lack of synchronization of video and audio streams is also one of the consequences
using the wrong wire.

Undemanding basic standard

the standard category of HDMI cables recognizes the picture in 720p quality or
1080i. The frequency at which such a cord operates is 75 MHz. Can
use the communication of devices that do not have special requirements
to content resolution; these are plasma, LCD panels, and DVD players.Quality
the final image, as well as the sound series, is devoid of priority here.
The bandwidth of the basic type of HDMI cable does not exceed 4.9 Gbps (and
often in the range of 2.25 Gbps), color characteristic (depth) – 24
bit, and streaming is a maximum of 165 megapixels. This is the only one of
of all manufactured types of cables, which lacks support for a reverse channel

ARC, 10.2 Gbps and other pluses of High Speed ​​

High Speed, it is compatible with popular types of video content encoding.Also, the manufacturer has implemented ARC support, allowing you not to connect another
wire for transmission of audio data.

It is necessary that
the equipment that is planned to be connected with each other knew how to work with such
reverse audio channel. In order to orientate users, manufacturers
the corresponding components indicate a combination of capital letters ARC.

High Speed
HDMI cable is suitable for communication of the following devices:

  • HDD type Blu-ray player.
  • Satellite receiver
  • LCD panel and plasma.

Cords of this
categories implement video transmission in 1080p up to 4K quality. Throughput
the capacity in this case is twice as high as that of its predecessor – 10.2 Gbps.
The color depth also doubled, and the frequency band increased to a mark of
1080 megapixels.

Two options with Ethernet link and car cable

Ethernet cable includes a set of parameters of the basic standard
cable, and also allows you to transfer content in both directions at a bitrate of 100
Mbps.But this speed can be ensured when implementing Ethernet HDMI in
connected equipment.

the ability to create high-speed communication with the Internet and
broadcasting data to other devices connected using an HDMI cable.
The developers have implemented the work of the considered category of cords with a reversible
sound transmission channel.

High Speed
type of cable with Ethernet support additionally allows transport
information at a maximum of 100 megabits per second.Finally, there is a wire
designed to connect HDMI devices to the on-board computer and other
devices installed in the car.

Connectors HDMI cable

Now worth
touch on the types of connectors installed on devices with the considered

  • Basic connector, labeled
    with the letter A, in demand for home use and is able to connect TV,
    projectors, DVD-players.
  • Micro HDMI (C) & Mini HDMI (D)
    designed for communication of portable equipment like smartphones,
    tablet computers or cameras.

HDMI connector 19 pin 13.9 mm by 4.45 mm ,.
The mini connector is used in cameras, cameras, mobile phones and has
technical parameters of a high-grade wire. Size 6.4 mm by 2.8 mm. Micro
is used in phones and tablets and is half the size of a mini.

Recommendations for choosing an HDMI cable

Looking through
various pages on the web, you can stumble upon a variety of guides,
concerning giving preference to one or another wire with the discussed interface.
Users are trying to highlight their own patterns of choosing a particular

Metal, from
of which the cable was made plays a role in shaping its operational
characteristics. But still, at the time of purchase, there is no way to fully test
cord work.Therefore, the consumer only has to trust the chosen one.
the developer and subsequently independently test the product. Actually,
this strategy can be called trial and error to some extent. TO
fortunately, in this difficult task there are certain observations that
it makes sense to take into account.

Is gold plating so reliable?

such a statement that the gold plating on the plugs improves the clarity of the transmitted
content.But gold is used to avoid the appearance of corrosion, which prevents
stable data transportation. However, such as nickel plating
provides less erasure of contacts. Another option is
purchase of wires with chrome plating. The applied gold is too soft, it is not
suitable for permanent cable extraction.

popularity of plating plugs with titanium nitride as opposed to gold, such
thus, the safety margin of the cable is increased.Therefore, titanium nitride will
better choice when operating the cord in high humidity. but
the catch is that these two defenses are not easy to visually distinguish. Nose
on the other hand, the quality of the data obtained will not differ dramatically.

Sources of signal distortion

As a rule,
digital transport does not impose special requirements on the used
wire. However, due to non-observance of all the subtleties during production
some distortion may appear.

the reason for the occurrence of artifacts is the broadcasting of content for tens of meters without
amplifiers. HDMI cables can vary in length, but due to the peculiarities
manufacture in the same way to transmit data. It is also worth not forgetting about the section –
thanks to its increase to 0.205 mm 2 it is possible to transfer data up to 25 meters without hindrance.

As a result
it turns out that the cross-sectional area of ​​the cable is directly proportional to the required length.The current article has already cited AWG units as an example, calibrations
conductors adopted in the United States. Larger AWG means
shorter HDMI cable length.

Length to cross-section ratio

At length
a cable of 5 meters is sufficient for a diameter of 7 mm, which corresponds to 28 AWG.
It is better to buy a 10-meter wire for a high-quality signal with a cross-sectional area,
equal to 8 mm (marked as 26 AWG). The cable should be another millimeter thicker
at a length of 15 meters or 24 AWG.When using a 20 meter cord
it would be more rational to give preference to the model with 22 AWG, i.e. from 10 mm to

One more
the nuance lies in the fact that with a large cross-section, good insulation is used
wires. The combination of these factors allows you to achieve high-quality
transportation of digital content. And the newer HDMI models are compatible with the versions
previously released. And although the digital format of broadcasting video is not too
picky about the cord of this interface, it is still better to focus on
the above cross-sections.

Supplementary interference warning

shielding allows you to protect the wire from pickup. Like twisted pair work,
“Plus” and “minus” of the signal pair along the entire length of the cable are intertwined with
“Minus”. This design reduces the interference caused by the signal
residential. In addition, the foil prevents the influence of interference from external

One more
a means of improving the stability of the transmission of content is to use
ferrite cylinders or rings.Filtration in this way allows
to prevent the influence of external interference with a high frequency. Total you can
claim that a satisfactory transverse area of ​​the cord in combination with
decent shielding makes it thick enough.

Essential Advantage of HDMI

There are people
who have not forgotten about the S-Video standard used with a composite conductor.
Although, of course, using the HDMI interface, it became possible to receive
quality to a new level.However, users are unlikely to appreciate it when
watching the final video. The obvious advantage appears when viewing
content of mediocre quality.

Sound row
so it is transmitted at a decent level. Implemented support for 8-channel
audio tracks with a bit width of 24 bits and a sampling rate of 192 kHz.
Lovers of technology such as Dolby TrueHD will appreciate the innovation
which are brought by HDMI.

One such
cable replaces 8 in case of traditional analog broadcasting.Naturally, most connoisseurs of high-quality sound are willing to
part with such a jumble of wires.

HDMI varieties

Question about
identification of a specific version of the released cord is interested in a considerable number
users. However, the first step is to delve into the characteristics in more detail.
currently manufactured models.

And all
began with the fact that HDMI Licensing LLC, which issued the standard, was
formed by the joint work of several popular organizations.Her brainchild was
designed to replace the outgoing SCART socket, which, in principle, was

physical layer, the discussed cable includes 19 conductors, which
connected by a single braid. The latter, in turn, contains the stipulated
layers of insulation. In the first version, 4.9 Gbps was the minimum
HDMI bandwidth. Good level of reproduction of the resulting picture
available due to the lack of a compression mechanism.

Change of product names

As already
reported above, version 1.0 was released back in 2002, taking a place on the market. But
soon the developers worked annually on the modernization of the cable family.
As a result of their efforts, 13 versions of cords have already been released. Latest version
2.1 presented in early 2017.

manufacturers have sought to improve the performance of HDMI cables, and
improve other operating parameters.Attention was paid
also to increase the functionality.

No wonder
get confused with a similar range of products on the market. AND
the company has agreed to no longer use numbers in product grading. In 2009
year the world saw a version with integrated support for 4K × 2K and Fast technology
Ethernet connections (1.4). Since then, there have been five types of standards, among
which are two basic, two high-speed and one automobile.

HDMI Standard

of this type can be freely used in the absolute majority
devices present in our everyday life.

HDMI has the following characteristics:

  • Max Resolution
    transmitted content is usually 720p or 1080i, much
    less often 1080p.
  • Least Slow Performance
    – only 4.9 Gbps.
  • Sampling rate – 74.25
  • 24-bit color depth.

the variant cannot provide excellent clarity of display and sound, therefore
suitable for broadcasting basic signals with connected undemanding
devices. Artifacts will be present here, therefore, for example,
this type of cable is hardly suitable for true moviegoers.

HDMI standard with Ethernet

Data cords
contain all the characteristics of the previous standard (including the supported
720p / 1080i resolution), but there was also a way to send content up to 100
Mbps.This is an Ethernet communication channel suitable for most household needs.

operation of the presented type of cable are as follows:

  • Mandatory socket support
    Ethernet HDMI by all communicating devices (only under this condition there is
    meaning to count on the efficient operation of equipment).
  • Parallel with connection to the World
    network the ability to transfer information to other components connected
    as described above.
  • Audio return channel,
    absent in the basic standard version.

Automotive version HDMI

the category of models under consideration has found its application in
audio systems of mobile equipment. Mostly used by specialists
on the installation of car sound. Resistant to harsh environments
operation, for example, constant vibrations, fluctuations in air temperature
or high humidity.

the version is maximally adapted for use in portable and
transported devices, as evidenced by the following functional

  • Communication of media systems with
    a standard on-board computer, which is an integral part of the new cars
  • Stable signal transmission in
    operating time.
  • The presence of a lock preventing
    spontaneous interruption of contact between vehicle devices.

High Speed ​​HDMI

This type
conductors opens the way to enjoying the excellent quality obtained in
the result of the picture. The variety of connected devices here is impressive – this is also
plasma, and LCD TVs, and game consoles, and players, including
including working with technology of 3-dimensional transmission of images.

Due to
that the high-speed HDMI conductor is transmitted from 1080p, it can
equate to the progressive standard 2.0. In addition to 3D, cable support also pleases
such functionality:

  • Using a 4K extension with
    the size of the picture is 4096 × 2160.
  • Working with Deep Color technology.
  • Maximum performance here
    already reaches 10.2 Gbps.
  • Color characteristic also
    has grown exactly twice, to 48 bits.
  • Frequency response expanded
    up to 340 MHz.

Best for 3D films

the type of cord connects seamlessly to other HDMI models.However, for these
purpose, you must use a connector belonging to type A. Of course, High Speed
stands out among the base models and the metals used in production, and
diameter. In addition, the differences also concern the principle of shielding and the level
manufacture of dielectrics.

the remainder, it turns out that the issue price here is clearly higher than in the case with
standard HDMI. On the other hand, an alternative in the form of an analog display format
video content is no cheaper.Therefore, it makes sense several
fork out for a digital version of the data broadcast. Otherwise, you will have to
to revise films without a three-dimensional format.

High Speed ​​HDMI & Ethernet

This type
cable has all the advantages of its predecessor. but
the developers have also implemented support for Ethernet, which allows you to transfer up to 100
megabits per second. But it is obvious that the capabilities laid down by the manufacturer
fully disclosed only if all connected gadgets are compatible
with Ethernet HDMI technology.

this kind of connection between different devices can be called the best
solving the issue of high-quality content transmission. Inherent in such a standard
versatility guarantees its relevance in the long term.

Extensive functionality also contributes to the demand for
the designated cable with an additional channel.

Connecting to old TVs

consumers are still using old generation television technology.The operation of such devices is satisfactory, but sometimes
it is necessary to “make friends” them with other devices. The owners of the devices of the previous
years of release are already ready to go for the use of special adapters.

in this case it seems to people that the simplest solution would be to take and buy
fresher TV. But here a serious obstacle is the price of the issue – not
everyone is ready for such expenses. And hardly a gradual reduction in the cost of LCD panels
can make a difference.For this category of users, there is an economical
a solution that does not require global changes in the interior and, as a result, in personal

Signal to analog conversion

We are talking about
buying a converter capable of connecting an “antique” TV and
laptop, PC, set-top box and other devices. Its name is HDMI to RCA, but this
there should be exactly a converter, since you can often find adapters with
with the same name.

But only
converters are capable of actively transforming digital encoding of data into
analog format – this function is beyond the power of adapters. This technique is still
described as HDMI “tulip” and works with resolutions 480p – 1080i
inclusive. The output jack of the device accepts 480i (NTSC standard) and 756i
(PAL standard). The color system is selectable and the power supply is realized
via the USB cable supplied with the converter.

Telephone TV

connections between a mobile phone and a TV can also be realized if there is
such a need. Some people are confident that in order to successfully solve this
the question is, you need to get a micro-USB-HDMI cable. On the one hand he has
there is a micro-USB output, and the other end must be connected to the HDMI jack.

less, here everything is somewhat more complicated than it seems at first and for uninterrupted
work of the above tandem needs two-way compatibility with MHL.it
obliges television equipment to have an HDMI / MHL port in its arsenal. but
this functionality is not available everywhere. But if in this regard everything
well, then the matter is limited only to the purchase of the specified adapter.

Some differences in the sold cords

One more
point to pay attention to when choosing the appropriate wire.
Manufacturers produce models with a different number of contacts. Samsung
there are 11 contacts, but other manufacturers complete the adapter only
5 contacts.

If not
forget about this fact, then all cables have the same layout – two connectors
micro USB and HDMI at their ends. For the rest, no adjustments are needed in
operation of devices. Remains in the settings of the device, from where the signal is transmitted,
select a specific mode.

But if
if the TV does not “know” what MHL is, then a USB adapter will come to the rescue –
HDMI, although in fact this is the same adapter. His job is to transform
MHL into a format understandable to the TV.Charger from any kit
can act as a power source for such an adapter.

Conclusion and Other Functionality HDMI

of the above parameters, the popular interface has in its arsenal more
several advantages. So, there is backward compatibility with devices,
operating on outdated DVI technology.

In addition,
data transmission is organized at a distance of up to several hundred meters
by means of a fiber optic cord.But there is a chance of breakage.
cable because it is already considered an active device. In case of occurrence
such force majeure will require replacement of wires.

is 10K, and the refresh rate of the display reaches 120Hz. Perhaps
an increase in the covered features in future versions of the interface.

How to connect a computer to a TV via HDMI + video 💻

If you have a large LCD or plasma TV, sooner or later there is a desire to connect a laptop or computer to it to watch a movie, or maybe work or just feel how it is 🙂 The temptation is not small and your hands itch 🙂

In the first part of the article I will talk about possible ways to connect devices, in the second part we will talk about the video card settings in Windows 7/8/10, and in the third part I will tell you how to output sound via HDMI.At the end there is a visual video describing everything that happens.

Connecting a computer to a TV via HDMI

I tried to work on a 32 ”Toshiba TV with a resolution of 1366 × 768 and I didn’t really like working with text, although designers and gamers will probably appreciate this possibility of connecting technology. In the simplest case, you only need one HDMI cable to connect your computer and TV. The cable has the same connectors at both ends:

The cable can be purchased inexpensively, just note that if you plan to use 3D mode, the cable must be HDMI 1 version.4 or higher.

Now you only need to find the HDMI jack on the back of the TV and the same on the computer. This is how the slots on the back of a television set look like:


And about such a socket you need to look for on the back of the system unit:

It is located directly on the graphics card next to the VGA or DVI monitor connection. With one correction, if you do not have a discrete video card, then the socket will be located on the motherboard, quite simply somewhere near the USB ports, but it will look the same.

It’s easier with laptops, their HDMI jack looks the same, except that in different models it is located on different sides:

Mini-HDMI connectors are used in compact devices such as tablets, netbooks, cameras and cameras. They are 3 times smaller in size and, accordingly, they need a mini-HDMI cable.

Often the TV hangs on the wall and it is impossible to insert a massive cable from the back. Cables with a 90 degree plug are sold specifically for such cases.There is also an option to buy an HDMI corner:

With the help of such a corner, you can connect both from the back and from the side. You can find a very cheap Chinese adapter, you are looking for a search query like “hdmi corner 90”. There are even ones with an adjustable angle and with a bend not straight, but to the side. Just before buying, estimate in appearance in which direction the cable will come out after connecting through the corner (up-down-right-left). There are simply corner adapters oriented to different sides, please keep this in mind!

Without HDMI connectors, you will not be able to connect.Unless, if there is a free connector for a DVI monitor, then you can buy a DVI-HDMI adapter and use it.

So, to connect the computer to the TV via HDMI, insert the cable into both connectors until it stops. Be sure to disconnect both devices from the network before connecting! Be sure to read about this in more detail in the article How HDMI ports burn out!

If some negative factors coincide, the HDMI ports or even the entire TV, computer or laptop may burn out!

If your TV does not have enough ports, you can purchase a so-called HDMI switch or “switcher”.It connects to just one input on the TV, and multiple sources can be connected to the switch. Using a button or a separate remote control, you can switch between devices:

You can buy ordinary Chinese switches for $ 10, and not those that are sold in computer online stores for $ 50-100 and more! It has already been tested by many people and everything works great even without an external power supply. The only thing is that if you are going to watch heavy 1080p movies through it, then you should look at the more expensive models.

HDMI connection setup

So, everything is connected and now it remains to tweak this business a little. If only one TV is connected, then the picture should appear immediately. Note that in order for the computer to boot on the TV, the monitor must not only be turned off, but disconnected from the system unit!

After Windows boots up, all that remains is to select the appropriate screen resolution. This can be done by right-clicking on an empty space on the desktop and selecting “Screen Resolution”

Here you can select your preferred resolution.The higher – the clearer the picture, but the smaller everything on the screen. By default, the system selects the maximum resolution that the device supports. You can leave it that way, if everything suits you. But if it is uncomfortable to work, the font is too small and difficult to read, then you can reduce the resolution, but there are nuances.

LCD TVs and monitors are designed to show a certain number of dots (pixels) horizontally and vertically, for example 1920 × 1080 (this is the matrix resolution).And if you set a non-standard resolution, then in order to display it on its matrix, the TV will scale it, and this MAY lead to a deterioration in the quality and blurring of the picture, or maybe everything will be fine anyway.

If your TV supports a resolution of 1920 × 1080 (Full HD), then it will also show well 1280 × 720, with all the details and fonts being larger. For an HD Ready (not Full HD) TV, it makes no sense to set it to 1920 × 1080, because its real resolution is 1366 × 768 pixels.

By clicking the “Additional parameters” button on the “Monitor” tab, you can set the refresh rate of the screen. I recommend setting 60Hz or more if your TV supports it:

The TV on this tab may be called not by its own name, but by something like “Universal PnP Monitor”. If, when watching a video, it twitches a little or does not go somehow smoothly, then you can experiment with this parameter. Color quality on this tab, select “True Color (32 bit)”.

For any change in resolution, frequency or color depth, the system will show a window to confirm the change. If the device does not work with the new parameters, then you will not be able to see this window and do not confirm your actions. No need to panic, just wait 15 seconds and the system, realizing that you do not see anything, will return the previous settings.

How to set up multiple displays

If a monitor is connected with the TV at the same time, then Windows 7/8/10 will consider that multiple displays are connected.In general, it doesn’t matter what it is, a TV set or a monik, for the system it’s all – displays.

There are two modes of operation for multiple displays: duplication (cloning) and desktop extension. This is selected in the same place where you set the resolution.

Screen mirroring

In the case of cloning, your desktop will be displayed the same on both devices. At the same time, the screen resolution is common for both devices, and it is impossible to set it differently, at least for now. If you know how this can be done, then please write to me in the comments 😉

It turns out that to use this mode, it is better to have both a TV and a monitor with the same resolutions, otherwise someone will have to work not on their own wave 🙂 Or the devices must be at least of the same format, for example, both widescreens.If the monitor is square (with an aspect ratio of 4: 3 or 5: 4), and the TV is widescreen (16: 9 and others), then the picture on it will be with black stripes on the left and right, like this.

Desktop Extension

Here everything is more interesting 🙂 This mode allows you to have two or more desktops. That is, if you put two displays side by side, then when moving, the mouse cursor will move from the monitor to the TV and vice versa.

The system assigns a number to each device, which is visible in front of the display name.If it is not clear who is under what number, then press the “Define” button and on all displays a large digit will be displayed on the whole screen with its number:

Above you can see pictures of devices with signed numbers, they mean the arrangement of displays in space. By dragging them with the mouse, you yourself set who is on the left, right or above, below. Click “Apply” and voila! The desktop expands to two displays. Using the corresponding checkbox, you can make one of the devices the main monitor, i.e.That is, where is the “Start” button, roughly speaking.

For a computer and a TV connected via HDMI, you can separately adjust the screen resolution and frequency, just as you did before for one device.

The settings for video cards NVidia, AMD (ATI) and others have their own options for installing multiple displays. For example, for NVidia GeForce series video cards, you need to right-click on an empty space on the desktop and select “NVidia Control Panel”. In the “Display” section you can customize your monitors:

How to output sound to TV via HDMI

First, you must have all the drivers installed on the video card.You can see if the HDMI audio output driver is installed in the “Device Manager”. To open it, press the “Win + Pause” buttons and select “Device Manager” on the left. In Windows 10, you need to right-click on the “Start” menu and select the item of the same name.

In the section “Sound, game and video devices” there should be something like “Device with support for High Definition Audio”, i.e. high definition audio support:

Secondly, in the playback devices (right-click on the speaker near the clock or “Control Panel -> Sound”) there must be a digital audio device (HDMI) or something similar in name.

Third, when the TV is connected to the computer, the device will change its status to “Ready”. Now you need to right-click on it and select “Use as default”.

Fourth, not all HDMI inputs can receive sound on different TVs! The port called “HDMI 1” should definitely be able to do this. If it does not work by itself, then you need to dig into the settings of the TV set for the use of digital audio stream for HDMI input No. X, and not analog (used when additional tulips are connected).

Setting up the sound on the TV, which is connected as a monitor, can be considered complete. Restart your programs or all Windows at once. If you have no sound at all on your computer or laptop, then read my article on how to solve this problem.

Results + video

That’s all, now you know how to connect a computer and a TV via HDMI to output video and sound. In the simplest case, you just need to take a cable and connect the two devices. Don’t forget the precautions I mentioned earlier!

90,000 Ethernet, Fiber, HDMI, DVI, etc.

We deal with cables every day, but do you know the maximum transmission distances of different cables? In this review, we will look at cable types and commonly used cable transmission distances.

1. Ethernet cable

An Ethernet cable is a twisted pair cable that has different transmission distances according to different characteristics of the network cable. They can connect routers, switches, firewalls and other network devices.The network cable carries network signals. If they exceed the distance that the network cable itself can withstand, the signal will be weakened. In severe cases, the network signal will be interrupted.

Categories 5 and 6 are 100 meters long, while conventional Category 6 oxygen-free copper wire can be up to about 120 meters. If you want to increase the transmission distance, you can install a repeater between two twisted pairs, and you can install a maximum of 4 cables. If 4 repeaters are installed to connect 5 network segments, the maximum transmission distance can be up to 500m.

2. Fiber Optic

The transmission distance of the Ethernet cable is limited and cannot solve the long distance transmission problem, then the optical fiber can be used for long distance transmission.

Optical fiber is always used with optical modules such as Cisco Optics modules.

Fiber optic is divided into multimode and singlemode. The transmission range of a multimode signal is longer than that of a network cable, but shorter than that of a singlemode cable.

V Ethernet 10 and 100Mbps multimode fiber can support transmission distance up to 2000 meters.

In 1Gbps gigabit network, multimode fiber can support transmission distance up to 550 meters. So multi-mode is less used now.

Compared with multimode fiber, singlemode fiber can support longer transmission distances. In 100 Mbps Ethernet and 1 Gbps networks, single-mode fiber can support transmission distances of more than 5000 m.

The components used in single-mode optical modules are twice the cost of multi-mode optical modules, so the total cost of single-mode optical modules is higher than the cost of multi-mode optical modules. The transmission range of single-mode optical modules can reach from 150 to 200 km.

Therefore, optical fiber can be used for long distance transmission, for example in remote monitoring projects.

3. HDMI cable

HDMI is a proprietary audio / video interface for transferring uncompressed video data and compressed or uncompressed digital audio data from an HDMI compatible source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device.


HDMI, commonly used in high definition displays, can be connected to HDMI display and regular display, and now many network devices can also be connected to a TV via cable for audio and video signals.

Normal HDMI signal transmission is less than 30 meters, then the maximum transmission distance is about 15 meters for a medium quality cable.

So how does HDMI transmit over long distances?

1) A conversion expander can be used.

HDMI signal does not pass through other equipment (120 meters transmission).

Generally, HDMI signals cannot be directly transmitted over 30 meters with HDMI cables, and there are almost no off-the-shelf HDMI cables longer than 30 meters on the market.

In this case, if the HDMI signal is simply passed to the display device and the HDMI signal does not pass through other devices, we can use a network cable to extend the signal. Use an HDMI network cable extension to extend the signal, and the HDMI network cable extension is divided into the sending terminal (HDMI in, network cable out) and the receiving terminal (network cable in, HDMI out) can be extended by 100 meters (Category 5) and 120 meters ( Category 6 network cable).

2) Of course, if you need to transmit further, you can also use an HDMI Fiber Optic Extender.

There are many ways to extend HDMI, you can also use HDMI fiber optic cable depending on the actual situation.

4. DVI cable

DVI is a digital video interface. The digital interface is used to connect a video source such as a video display controller to a display device such as a computer monitor.A regular DVI cable can only effectively transmit the signal over a distance of about 5 meters, and signal attenuation will occur if it is more than 5 meters. This drawback severely limits the popularization and use of DVI equipment.

DVI-D can only accept digital signals; DVI-I can receive both digital and analog signals simultaneously with a short transmission distance of 7-15 m.

5.VGA cable

The VGA cable carries analog signals.This is a data cable that connects a computer’s graphics card to a monitor or TV to transfer information. It is responsible for outputting the corresponding image signal to the display and is the bridge between the computer and the display.


VGA cable is widely used in the field of color display, but it is easy to loosen, has a short transmission distance and is easy to interfere with. But its transmission range is higher than that of HDMI and DVI, and the 3 + 4 / 6VGA transmission range is 20-40m.

6.RS232 and RS485

1) RS232

RS232 transmission distance is limited, the maximum standard transmission distance is 15 meters, and it can only be point-to-point communication, the maximum transmission rate is 20KB / s.

2) RS485

The maximum RS485 wireless transmission distance is 1219 meters.The maximum transmission rate is 10 Mbps, and the maximum communication distance can be reached at a transmission rate of 100 Kbps.

Using impedance matching, special low attenuation cables can be up to 1800 meters! More than 1200 meters, repeaters can be added (up to 8), so the transmission distance is close to 10 km.

7.USB cable

The abbreviation USB (Universal Serial Bus) is an external bus standard used to regulate the connection and exchange of data between computers (such as laptops, workstations, etc.).) and external devices. It is an interface technology applied in the PC field. The USB interface supports plug-and-play and hot-plug functions.

The effective distance of the USB protocol is 5 meters, a longer USB extension cable can be used. The quality of the cable is better. Poor quality USB extension cables cannot reach 5 meters.

Cable connecting the main computer to the monitor – Knowledge

Cable connecting the main computer to the monitor

When gamers discuss the configuration of the computer, the most talked about the performance of the video card. The graphics card is not only the basic configuration of a computer, but also one of the important accessories. Is it always said that the higher the performance of a video card, the higher the configuration of the computer?

So what is the graphics card that has been transferred so much? The graphics card is called the display interface card.The terminal knows that its most important core is the interface.

Because people focus too much on graphics card performance, they will always ignore the interface. As long as the performance of the graphics card is high, all aspects are considered to be perfect and there is no need to worry! If you think so, then your overall so-called high configuration will be defeated on this small interface. The interface on the computer is constantly improving as the version of the computer is updated. The types and versions are different.The three most common interfaces are DVI, VGA, HDMI.

VGA interface:

First of all, VGA interface is the longest interface that accompanies computer game players so far, VGA interface transmits signals in the form of analog signals, like the interface interface that was once used when VGA was just came out because of its high resolution. High speed and richness. Color is widely used in the display field.

Although VGA has phased out from high-end computers and display interfaces with the introduction of HDMI and DVI, it has persisted in some LCD TVs and budget computers.On the one hand, due to the low cost of the VGA interface, on the other hand, due to digital display devices such as LCD and DLP, VGA interface is still required for analog / digital signal conversion.

DVI interface:

The DVI interface is divided into the DVI-I and DVI-D specifications, and the DVI-D interface is compatible with the DVI-I interface.

DVI is a digital video signal interface. One of the great advantages of digital signal transmission is the high speed.The VGA interface needs to do analog / digital conversion at the time of transmission, and the transmission speed is a bit slow, while the DVI interface does not require a complex conversion process and is transmitted directly. Transfer speed has been significantly improved, while smear and dunk phenomena have been eliminated.

When the VGA interface completes the A / D conversion, it will inevitably cause some signal loss, and this will affect the picture quality. The DVI interface is completely skipped at this stage, the transmission is not consumed, the image quality becomes clearer, and the color is more vivid.Much progress has been made in image detail.

HDMI interface:

Due to the knowledge of some people on the Internet, many people think that the difference between DVI interface and HDMI interface is very different. In fact, when using the same hardware and resolution, the image quality of the two devices connected to the device is almost invisible to the naked eye. The main reason is that both interfaces are digital interfaces. Although the image quality may vary slightly due to performance differences, it is almost the same in practical applications, but HDMI is indeed more functional than DVI.
