Connecting a TV to a computer in different ways. How to connect a computer to a TV: the best ways and methods

Modern plasma TVs have little in common with the rectangular units with convex screens that used to be in every home. They boast outstanding technical characteristics, high image clarity and a number of additional functions. Nowadays, connecting a TV to a computer no longer seems surprising or fantastic.

Many PC and laptop owners are trying to expand the scope of their devices. And so they have a completely logical question: “How to connect a TV to a computer?” Let's talk about this.

Why is this needed?

Each user determines for himself whether he needs equipment connected to the TV or not. In fact, there are many reasons that push us to take such a step, and in each individual case the question arises of how to connect a TV to a computer and how difficult it is.

Before answering it, let’s consider the main advantages of such a “tandem”:

Computer games on the big screen.
Watching movies and videos.
Communication via Skype.
Launch various slide shows, etc.

On the hard drive of a modern computer, thanks to unlimited Internet tariffs, a huge amount of various content accumulates - games, films, music videos, videos, photographs, etc. And sometimes you really want to try it all in a “new format” - display it on the big screen . And to do this, you need to understand how to connect a computer to a TV.

Features of connecting various equipment

In general, the possibility of “combining” different technologies has appeared a long time ago. Even old TV models and not very modern PCs can be connected to each other. However, this will require a special video card and cables. It should be noted that the quality of the resulting picture will not be very high, so not many people previously tried to connect a TV to a computer via VGA.

Modern audio and video equipment is much more technologically advanced and sophisticated, which is why the need to set up a connection arises much more often.

At the moment, three main ports are used to carry out this procedure:

HDMI.

In some cases, difficulties arise with the VGA port, because it is often completely absent on modern video cards. Many laptop models, as well as plasma TVs, are produced without it. Therefore, it is better to use the other two options or purchase the appropriate VGA-DVI adapter.

Connection via VGA interface

Despite the fact that these types of connectors are losing their position, many users continue to use them for work. Most still have old equipment in good condition. And quite a few people are now digitizing videotapes, viewing recordings from old hard drives, etc.

The VGA interface is considered obsolete. It provides image transmission using analog signals at low speed (by today's standards).

If you have the appropriate equipment that supports these ports and special cables, you can both connect the TV to your computer and perform further setup.

The procedure is carried out in several stages:

The power to both devices (TV and computer) is turned off.
The cable is connected to the appropriate connectors.
Devices turn on.
Settings are being made in Windows.

It’s easy to guess that connecting a TV to a computer itself does not cause any particular difficulties. Much more questions arise when it comes to setting up Windows directly. Without this, it is impossible to achieve a high-quality connection.

If the image is not transmitted to the TV or any problems or interference are observed, then, most likely, errors were made in the settings. Particular attention should be paid to the display modes - “only on TV” or “display and TV at the same time”.

If you need to connect the TV to a VGA computer, you should make the following settings in the operating system:

On the desktop, in the context menu (right mouse button), select "Screen resolution".
Open the Screen panel.
Select the required display mode.
Apply and save.

In some cases, you will additionally need to do a little adjustment of the TV - select the VGA signal source in the appropriate menu.

Advantage of DVI and HDMI ports

Nowadays, when the question arises of how to connect a computer to a TV, many experts advise using HDMI and DVI ports. They look different, so it is almost impossible to confuse them. Also, if necessary, you should use various adapters. You can find the necessary interfaces on the back panel of the system unit, as well as on the back and sides of the TV and laptop.

Why is it better to connect your TV to your computer via HDMI?

The advanced technology has gained enormous popularity among both specialists and ordinary users. Currently, modern LED TV models have up to 2-3 HDMI connectors, so there are no connection problems. You just need to purchase the appropriate cable.

The DVI port is in many ways similar to HDMI - it also allows you to transmit signals in digital quality. Corresponding adapters are commercially available, so these ports are almost identical in their ability to perform the task.

What should you pay attention to when connecting your computer to an HDMI TV?

Display and TV resolution.
Correct connection.
Settings in the operating system.

Usually, no special problems arise during the connection process, but you still need to pay attention to every detail. This is especially true for matching screen resolutions.

If you use HDMI from a computer to a TV, the latter will take over the functions of the primary display. If at this moment both the main monitor and the LCD TV are connected, then it is necessary to configure the display modes.

Some modern TVs have an actual resolution of 1400 x 1900 pixels, while the video cards of personal computers and laptops are set to the “standard” 1280 x 720 or 1920 x 1080 pixels. With such a discrepancy, the TV often produces just a black screen. To correct the situation, it is necessary to set the exact parameters in accordance with the characteristics of the equipment.

If you are trying to figure out how to connect a TV to a computer for the first time, experts recommend also connecting the main monitor (for example, via DVI or VGA) or using a laptop. Then it becomes possible to change the settings of the operating system or video card drivers.

HDMI connection process

To complete this task, you must purchase an HDMI cable. In specialized stores you can find products of any length (from 1 to 20 meters). Next, you should find the corresponding ports on the TV and PC.

Thus, the main connection steps are:

Direct connection of devices (when switched off).
Turning on the computer and TV (waiting for full loading).
Switch on the TV to the corresponding HDMI port (source - port).
Setting up a connection in Windows OS.

As a rule, the default is to display only on the second display, i.e. the TV becomes the main one. Due to a resolution mismatch, the image may not be transmitted. To understand how to connect a computer to a TV, you need to dig into the settings.

It is best to select “Multiple monitors” in the “Screen” menu, and also select the “Duplicate screens” option. After this, everything should work, and the Windows desktop will be displayed on the TV.

To obtain the highest quality image, it is necessary to accurately determine its resolution. Usually in this question the main attention is paid to it (otherwise why did the TV need to be connected at all?). By properly connecting your TV to your computer via HDMI, you can freely work with your new screen.

Problems with sound transmission

Displaying a picture on the TV screen is only half the battle. Sound settings raise a lot of questions. As a rule, with such an approach, you want to use all the available capabilities, including the correct output of an audio signal. Modern plasma TVs are often equipped with good, powerful speakers, and third-party audio systems are also connected to them, so using them is much more reasonable than standard laptop speakers. In the case of a desktop computer, difficulties often arise due to the lack of any systems for sound output.

In some cases, getting the right sound through your TV speakers can be quite difficult. Common problems when connecting the mentioned device are:

Complete absence of sound.
Various interferences.
Sound delay.
Low volume.

As you can see, there are several options, so first of all you need to deal with the root cause of the problem.

Sound settings features

When the TV is connected to a computer, sound is also transmitted through the HDMI cable used. As with image adjustments, in some cases you will have to try different options.

The HDMI interface is a universal high-definition multimedia cable, and this is its main advantage. That is, having only a standard adapter for this connector, you can solve the problem of making a full connection. And for this you will not need to purchase additional cords, etc. Since HDMI, along with USB, is considered a widespread global standard, this leads to the fact that many types of equipment support it.

Thus, when making a connection, the HDMI cable performs two main tasks:

High definition image transmission.
Transmission of surround stereo sound.

Versatility is also evident in the settings. With some models of computers and televisions there is no such need at all. In other situations, you will need to change something in the operating system settings. There is almost never any need to install additional software, except perhaps to simplify management.

Primary connection of two devices

When we work with this or that technology, we try to take advantage of all the inherent possibilities. When connecting a TV to a computer with HDMI, we face various difficulties. First we set up the image, and then everything else. But sometimes we find that with a full connection, the sound is still transmitted through the small laptop speakers or PC speakers. What to do in such situations?

It is necessary to configure the sound signal transmission. Let's start with the "Taskbar":

The "Hardware and Sound" menu in the "Control Panel".
Opening tab "Manage audio resources".
AMD HDMI Output item.

Finding all this will not be difficult, because all the settings are literally on the surface, so the whole procedure will only take a couple of minutes.

There are several aspects that you should pay special attention to. If the video card of your computer or laptop supports audio transmission, then you can set the “Digital Audio S/PDIF” item in the AMD HDMI Output parameters. Otherwise, the audio signal will be transmitted through the motherboard, which must also be connected to the video card with an S/PDIF cable.

Additional Settings Options

It is necessary to understand that specific equipment, despite uniform standards, still has its own characteristics. That is why sometimes difficulties arise even if all the rules and recommendations are followed. What should you do if you still experience connection problems?

Check the serviceability of the equipment.
Update drivers (primarily sound drivers).
Try other settings options.

Not all users know about all the basic parameters of a PC or laptop and the TV itself. And in order, for example, to connect an LG TV to a computer, you have to study the technical specifications.

What problems are most common?

To transmit audio via HDMI, you must have the appropriate driver. We are talking about support for High Definition Audio - a high-definition audio signal.

To check the presence of this driver, go to the "Device Manager" menu, which is located in the taskbar of the operating system. And already there you need to select the “Sound, video and gaming devices” tab. Next, you should carefully study the proposed list and find there “Device supporting High Definition Audio,” which was already mentioned above. If such an item is present, then the computer is capable of transmitting an audio signal via an HDMI cable.

What should you do if you don't have the appropriate driver?

In this case, you will need to download and install it. There should be distribution kits for installation on the laptop or specific sound card manufacturer's website. In addition, in some cases, the OS is independently capable of identifying the missing drivers for correct operation.

Another option for configuring the system is to check the available playback devices. Finding them is not difficult - in the system tray (lower right corner of the computer screen) you need to find the sound playback icon. If you right-click on it, a context menu will open, one of the items labeled “Playback devices”.

This is where the connected TV should appear, along with other options (speakers and headphones). All you have to do is select it and click “OK”.

Setting up a wireless connection via Wi-Fi

Today, modern models of laptops and TV devices allow you to use a variety of options, including connecting a TV to a computer via wireless networks.

What will it take to create such a connection? First of all, of course, you need to pay attention to the characteristics of the TV. Unfortunately, at the moment only advanced models support data transfer technology via Wi-Fi. In addition, if you wish, you can try a special adapter for TV, connected via a USB port.

The advantages of such a connection are obvious:

Simple connection without using wires.
Free arrangement of devices (no need to move the computer).
Ability to view files directly from your hard drive.
Internet access.

In this case, however, you will need additional software - a special utility that comes with the TV. It would be a good idea to look at the official website of the device manufacturer.

As a rule, the main task of the mentioned utility is to quickly connect a computer via WiFi to a TV, so the interface is quite simple and understandable. Most often, a special folder is created on the PC hard drive into which files for TV are sent.

Many users use a router (router) to solve such problems. A single Wi-Fi network covers various devices, including a plasma TV. As a result, you can freely view various files.

General conclusion

If there is a need to combine two devices, you need to select the appropriate solution to the problem. The most popular is to connect the TV to a computer via HDMI or via Wi-Fi wireless networks.

When connecting, first of all, you should set up the correct image transmission, and then check the quality of the supplied sound (in this case, you need to make sure that the drivers are available and select the items related to the signal source in the menu).

To set up a Wi-Fi connection, most often it is enough to use special software that will solve the problem on its own.

Today, modern LCD and LED TVs have almost completely replaced television receivers with a cathode ray tube, or simply a kinescope. Modern TVs are distinguished by high quality image and sound, but in addition, LCD and LED TVs are perfect for use as a monitor.

Advantages and disadvantages of connecting a TV to a PC

Their matrix allows you to work quite comfortably with any applications, watch movies from the Internet on a wide screen and play, view photos and social network content, as it does not create flicker and does not harm your eyesight.
In addition, purchasing an LCD TV as a computer monitor is quite beneficial from an economic point of view. You can watch TV channels and work on a PC without buying a separate monitor for it.
A television receiver connected to a PC can be used as a signal source for recording broadcasts to the computer’s hard drive.

But this is where the advantages of using a modern TV as a monitor end; let’s move on to the disadvantages, the main one of which is the different size of the pixels: in the TV they are larger, and in the monitor they are correspondingly smaller. This is why the image quality from the PC will not be as rich as it could be on the monitor. Besides:

If the TV resolution is less than 1920 x 1080, the clarity of the image deteriorates significantly and the angularity of the fonts can be seen.
Many budget LCD TVs have low matrix response. Any fairly dynamic content on such a device will not look very correct.
For surfing the web, a widescreen TV with a large diagonal will also not be a good choice. For a normal view, you will have to work with such a device from a great distance.

However, many people are interested in how to connect a computer to a TV and use it instead of a monitor for playing games and watching movies.

Video adapter requirements

The video card must be equipped with two connectors - this is the most important requirement for it. As a rule, most video adapters have 2 VGA connectors or a combination of VGA and DVI connectors, but more modern ones have a pair of high-speed HDMI digital interfaces. However, depending on the manufacturer and model of the video card, the combination of connectors may be different.

Let's take a closer look at connecting an external screen instead of a monitor using a VGA cable, since all video cards and more than 90% of television receivers are equipped with this interface.

Connection and configuration process via VGA interface

Connecting a computer to a TV begins with purchasing the necessary VGA-VGA cable at any computer hardware store. As for the cable length, it is better to take 1.5 distances from the required one. In case of furniture rearrangements, repairs, etc. you don't need to disconnect your PC from your TV or buy a new cable.

As a rule, connecting a TV to a computer via a VGA interface is not difficult even for an inexperienced user. If everything is in order with the equipment and cable, the TV as a monitor should work immediately.

Only the image is transmitted via the VGA cable. To connect sound, you should use an audio cable, connecting it to the output of the sound card and the television receiver.

Connection and setup process via HDMI interface

This is the most suitable option, since the HDMI digital interface transmits not only video, but also sound, and therefore no additional audio cable is needed.

Sound problems

Despite the fact that not only video, but also sound is transmitted via the HDMI interface, it often happens that the sound comes from the PC speakers, but is not transmitted to the TV. The most common reason is settings.

After this procedure, the sound will come from the television receiver and not from the PC speakers. In this simple way, you can always connect your PC to your TV. Good luck with your purchases and enjoy your viewing.

The idea of connecting a computer or laptop to a TV may be quite reasonable if, for example, you often watch movies stored on your hard drive, play games, want to use the TV as a second monitor, and in many other cases. By and large, connecting a TV as a second computer or laptop monitor (or as the main one) is not a problem for most modern TV models.

Step-by-step instructions for connecting a TV to a PC or laptop

Let's start directly with connecting the TV and computer. To begin with, it is advisable to find out which connection method will be optimal, least expensive and provide the best image quality.

Connectors such as Display Port or USB-C/Thunderbolt are not listed below because such inputs are not currently available on most TVs (but I do not rule out that they will appear in the future).

Step 1. Determine which video and audio output ports are available on your computer or laptop

These are all the main types of connectors used to connect a TV to a laptop or PC. Most likely, you will have to deal with one of the above, since they are usually present on TV.

Step 2: Determine the types of video inputs present on the TV

Look at what inputs your TV supports - on most modern ones you can find HDMI and VGA inputs, on older ones - S-video or composite input (tulips).

Step 3: Choose which connection you will use

Now I will list in order the possible types of connecting a TV to a computer, first - the optimal ones in terms of image quality (besides, using these options, it is easiest to connect), and then - a couple of options as a last resort.

You may need to purchase the appropriate cable from a store. As a rule, their price is not too high, and you can find various cables in specialized radio stores or in various retail chains that sell consumer electronics. I note that various “gold-plated” HDMI cables for wild sums will not affect the image quality at all.

HDMI-HDMI. The best option is to simply purchase an HDMI cable and connect the appropriate connectors; not only image but also sound will be transmitted. Possible problem: .
VGA- VGA. This is also an easy-to-implement way to connect a TV; you will need an appropriate cable. These cables are included with many monitors and you may find one you don't use. You can also buy it in the store.
DVI-VGA. The same as in the previous case. You may need either a DVI-VGA adapter and a VGA cable, or just a DVI-VGA cable.
S-Video-S-Video,S-Video - composite (via an adapter or appropriate cable) or composite - composite. Not the best connection method due to the fact that the image on the TV screen will not be clear. As a rule, it is not used in the presence of modern technology. The connection is carried out similarly to the connection of household DVD, VHS and other players.

Step 4: Connect your computer to your TV

I would like to warn you that it is better to perform this action by completely turning off the TV and computer (including unplugging it from the outlet), otherwise, although not very likely, damage to the equipment due to electrical discharges is possible. Connect the necessary connectors on the computer and TV, and then turn on both. On your TV, select the appropriate video input signal - HDMI, VGA, PC, AV. If necessary, read the instructions for the TV.

Note: If you connect your TV to a PC with a discrete graphics card, then you may notice that on the back of the computer there are two locations of video output connectors - on the video card and on the motherboard. I recommend connecting the TV in the same location where the monitor is connected.

If everything was done correctly, then, most likely, the TV screen will begin to show the same thing as the computer monitor (it may not start, but this can be solved, read on). If the monitor is not connected, it will only show TV.

Even though the TV is already connected, you will most likely experience that the image on one of the screens (if there are two of them - a monitor and a TV) will be distorted. You may also want your TV and monitor to display different images (the default is mirror image, which is the same on both screens). Let's move on to setting up the TV-PC connection, first on Windows 10, and then on Windows 7 and 8.1.

Adjusting the image on TV from a PC in Windows 10

For your computer, the connected TV is simply a second monitor, and accordingly, all settings are made in the monitor settings. In Windows 10, you can make the necessary settings as follows:

In general, the setup can be considered complete at this point, except that you should make sure that the correct resolution is set for the TV (i.e. the physical resolution of the TV screen), the resolution is adjusted after selecting a specific screen in the Windows 10 display options. two displays, instructions may help: .

How to adjust the image on a TV from a computer and laptop in Windows 7 and Windows 8 (8.1)

In order to configure the display mode on two screens (or on one if you are going to use only the TV as a monitor), right-click on an empty space on the desktop and select “Screen Resolution”. The following window will open.

If you have both a computer monitor and a connected TV working at the same time, but you don’t know which one corresponds to which number (1 or 2), you can click the “Detect” button to find out. You will also need to clarify the physical resolution of your TV, as a rule, on modern models it is Full HD - 1920 by 1080 pixels. The information should be in the operating instructions.

Settings

Select the thumbnail corresponding to the TV with a mouse click and set the “Resolution” field to the one that corresponds to its real resolution. Otherwise, the picture may not be clear.
If you use multiple screens (monitor and TV), in the “Multiple displays” field, select the operating mode (more details below).

You can select the following operating modes, some of which may require additional configuration:

Apply the settings and enjoy. The best option, in my opinion, is to expand the screens. At first, if you have never worked with multiple monitors, this may not seem entirely familiar, but then you will most likely see the benefits of this use case.

I hope everything worked out and is working properly. If not and there are any problems with connecting to the TV, ask questions in the comments, I will try to help. Also, if the task is not to transfer an image to a TV, but to simply play a video stored on a computer on your Smart TV, then perhaps a more optimal method would be.

Modern monitors are increasingly starting to catch up with TVs. Just 10 years ago, monitors with a screen diagonal of 24 inches would have been the dream of any user, but today they are an inexpensive and quite accessible reality.
And still, this is not enough for users and they want to connect a large LCD TV to their computer to watch movies and play games comfortably. Moreover, modern TVs allow you to do this without problems. But if the task itself is quite clear and understandable, then there may be a hitch with the implementation.
Then I suggest you take a closer look - what cable is needed to connect the TV to the computer?!

At the time of writing (and this is the end of 2016), there are several main connection types:

DisplayPort (DP)
LAN (Ethernet)

The most interesting thing is that modern TVs are so versatile that they have at least two of them at once, or even all of them at once. Here's a clear example:

This budget Samsung has 3 ports at once, using which you can connect a laptop or PC to it.

At the same time, a modern computer video card has two or three different connectors:

Laptops, netbooks and ultrabooks are also not far behind:

Let's look at each connection option in more detail.

Analog VGA

Video Graphics Array— VGA is practically the oldest standard, developed by IBM and used to connect monitors 30 years ago, back in 1987. It can still be found on cheap video cards and inexpensive laptops. It only transmits video. The audio signal is not transmitted through the VGA.

Digital DVI

Digital Visual Interface - DVI - a more recent video transmission standard. It appeared as soon as LCD monitors with a diagonal of more than 19 inches began to appear due to the fact that the old analog VGA could not provide high definition at high resolutions.
Unfortunately, the DVI port on LCD and plasma TVs is not common, and therefore this cable is used least often to connect a TV to a computer.

Common HDMI

High-Definition Multimedia Interface— HDMI is the most common port on modern equipment. Initially developed for connecting video equipment working with HD video. It is available on video cards, media players, TVs and laptops. The best part is that it can transmit not only video, but also audio. In addition, as a rule, in order to connect a TV through a computer, you do not need to install additional software on the latter except the video adapter driver.
It should also be noted that now there are several types of HDMI connector - in addition to the usual Type A, there are also Mini (Type C) and Micro (Type B).

Smaller connectors have appeared for connecting various portable equipment to TV - tablets, camcorders and cameras. Such connectors are usually not found on PCs.

Modern DisplayPort

Today, DP or DisplayPort is the most modern solution for connecting video equipment. This cable has the highest bandwidth - up to 10.8 GB/s). You can find a DP connector on many modern video adapters and, in principle, this is the most successful option for connecting a TV to a computer or laptop.

Connect the TV to the computer via a LAN (Ethernet) port

The presence of a LAN connector on the TV allows you to connect it to your home local network (LAN). To do this, you will need this cat 5e Ethernet cable.

Moreover, you can connect the TV and computer either directly or through a router. This is perhaps the best option for SMART TV, because it allows you to give it access to both a PC and the Internet. And if you have a NAS-type network storage device, then you will also have access to your movies, photos and music on your TV.

So, you are the happy owner of an LED, LCD or plasma TV. And of course, you probably already read in the instruction manual that any personal computer can easily be connected to it, thereby turning it into a large monitor. After this, you can not only enjoy your favorite games on a huge screen, but also, for example, watch videos in 3D format if your television receiver supports this function. That is, in this case, you can safely do without a Blu-Ray player. It does not matter what kind of PC you have - “standard”, i.e. in the form of a system unit, laptop or netbook. The standardization of connection interfaces allows you to easily perform this operation without any tricks or “dancing with tambourines.”

We carry out a technical “audit”

Before you move directly to connecting your PC, you need to find out what set of interface connectors your television receiver has. Today, manufacturers can install the following connectors for connecting external video devices:

Carefully inspect all the connectors that your television receiver and personal computer have. Determine what types of interfaces are present on them.

What is required to connect?

In order to connect a PC to a television receiver, you will need a special interface cord and, possibly, a driver for the computer to work correctly with your TV. After you decide on the interfaces available to your equipment, you will need a cable that has the appropriate interface connectors.

Cords, cables and adapters for connection

An interface cord may be included with your TV or personal computer.

In addition, such a cord can be used from a connected DVD or Blu-Ray player by borrowing it for a while.

VGA cable:

DVI cable:

HDMI cable:

Adapters

In addition to the so-called standard cables, which have connectors at both ends for connecting to the same type of interface, there are cords designed to connect devices with different interfaces.

For example, a PC with a VGA video output can be very easily connected to a TV that has a DVI input using a DVI-VGA adapter cord. This is due to the fact that the technical parameters of some of the main signals in these interfaces are the same. Special adapters for these connectors are also produced.

You can purchase these cable products and adapters in a showroom that sells radio equipment or in a specialized radio store.

If your television receiver does not have HDMI connectors, but only has a VGA or DVI input, then you will need another additional cable to output audio to the TV. As a rule, this is an audio cord that has a standard 3.5’’ mini-jack connector on both sides. Take care of it in advance before connecting.

To connect, you need to connect your PC and TV to each other using an HDMI cable. In this case, on both devices the cable must be connected to the connector labeled HDMI.

Turn off the power on your PC and TV.
Connect the TV and your personal computer using a cable.
Turn on the TV and give it a few seconds to enter operating mode.
Turn on your personal computer.
On your TV, select the appropriate connection type – HDMI input. If you have several of them, then select the one to which you connected the PC accordingly.
If everything is done correctly, the operating system will load on the screen.
After the OS is loaded, it is possible that the operating system will ask you to install a driver for an external video device - that is, your TV, because for a PC, a TV is a “new monitor”, i.e. other equipment. If there is no driver on the disk that came with your television receiver, try searching for it on the Internet on the website of the manufacturer of your TV. If you cannot find it, do not install it and work with the standard operating system developer driver.

If you have any problems with audio output to TV via HDMI interface, check the properties of the audio system - lower right corner, "speaker" icon in the system tray. Right-click on it (!) and select “Playback Devices”. Then in the “Sound” window that opens, select your television receiver and click the “Default” button. This will switch the sound output not through the audio output of your PC, but through the HDMI input of the TV. If for some reason your television receiver is not in the list, turn it off from the network and turn it on again without leaving this menu. If these steps do not help, try restarting your PC.

For connection, use a DVI or VGA cable, respectively, and for different interfaces on the PC and television receiver, use an adapter or a corresponding “adapter” cable.

Turn off power to all devices.
Connect your TV and your personal computer using a DVI or VGA cable. If necessary, use an adapter or “transition” cable.
Using an audio cable, connect the output of your PC's sound card and the audio input of your TV to output sound to the TV receiver. If you do not want to listen to sound on your TV, you do not need to connect this cable. In this case, you can listen to the sound on the PC speaker system, if you have one, or using headphones connected to the output of the sound card.
Turn on your TV and wait a few seconds until your TV is ready to use.
Turn on your PC.
Select the appropriate connection type on your TV – VGA or DVI input.
If you did everything correctly, you will see the operating system loading on the screen.
If after loading the operating system asks you to install additional drivers for the new device, follow the same recommendations as for an HDMI connection.

Try never to disconnect or connect interface cables while the power is on on devices. Otherwise, this may lead to damage to the interface input, or even failure of one of the devices!
