To do this, inspect the connectors available on the device. If you cannot determine the types of ports by eye, find their description in the documentation for your computer. Depending on the device model, you can see the connectors of the following varieties:
- HDMI is a digital interface found on most modern computers. It transmits both audio and video, and therefore is optimally suited for outputting a multimedia signal to a TV.
- DVI is another digital port widely used in the market. Transmits only video, no sound.
- VGA is a popular analog connector. Like the previous port type, it only outputs video signal.
- Mini DisplayPort , Thunderbolt 2 , USB‑C and Thunderbolt 3 (USB-C) are digital interfaces found on Apple computers. All of them transmit video and sound. In addition, the Mac can be equipped with an ordinary HDMI connector.
There are other types of connectors. But we have listed the most popular ones. Your device is probably equipped with one or more of them.
2. Determine which connectors for signal reception are on the TV
Look at the TV ports. Most modern models have HDMI and VGA connectors. Older ones are equipped with RCA format ports, the plugs for which are called tulips:
3. Select a cable according to the available connectors
If you have an HDMI TV
If both the TV and the computer have an HDMI connector, then everything is elementary: you can connect devices using an HDMI cable. This option will be optimal.
To connect a computer that does not have an HDMI port to an HDMI TV, you will also need a special signal converter along with an HDMI cable. Which one depends on the connector available on the computer. These can be DVI → HDMI, VGA → HDMI or other adapters to HDMI.
In addition to the HDMI cable, you can often connect an additional audio cable to such converters, the other end of which is inserted into the computer. This allows you to transmit audio bypassing the limitations of DVI and VGA. An audio cable is often sold with a converter.
www.amazon.com To connect to a Mac HDMI TV with a Thunderbolt 2 or Mini DisplayPort connector, you will need a Mini DisplayPort to HDMI adapter along with an HDMI cable. For it to transmit sound, ask the store for such an adapter with audio support.
If you have a VGA TV
For a VGA TV, the procedure will be similar. Only you will need an HDMI → VGA, DVI → VGA or other converter, depending on the computer port. The main thing is that it converts the signal to VGA.
If you have an RCA TV
If you have a very old TV model with tulips at your disposal, then converters like HDMI → RCA, VGA → RCA and others that output an RCA signal are suitable.
In order not to make a mistake when buying a cable or converter, you can tell the seller the types of connectors on your TV and computer: he will select the appropriate option for you or check your choice for compatibility.
4. Connect devices via cable
Turn off your computer and TV beforehand for safety reasons. Next, connect the devices using a cable (and, if necessary, a converter). Only then turn on the devices. If the TV does not automatically detect the computer as the signal source, then do it yourself in the TV settings.
5. Adjust the picture on the TV using a computer
If the image is blurry, open the system settings on your computer and find the section responsible for the monitor. Here you can set the resolution that matches your TV and, if necessary, change the video display mode.
How to connect a computer to a TV via Wi-Fi
Modern smart TVs can be connected to computers wirelessly via a local Wi-Fi network. Technologies like DLNA and Wi-Fi Direct allow you to broadcast video, music and other content to a TV screen or completely duplicate the image from a computer on a TV, turning the latter into a wireless monitor. And in the case of Wi-Fi Direct, you don’t even need a router for this.
For example, on LG devices for such functions there is a service. And Samsung TVs offer similar features as part of the AllShare service.
Wireless connection settings may vary depending on the manufacturer and model of the TV. Some devices establish a connection in a semi-automatic mode. Others require additional software to be installed on the connected computer.
Therefore, it is difficult to formulate a universal instruction that will suit all users. If you want to connect your TV to a computer via Wi-Fi, you will find the necessary information in the paper manual or on the official website of the manufacturer along with the software needed for this.
Those who work behind the keyboard, over time, begin to lack workspace. No matter how big the screen is, all the windows do not want to fit on it at all, and even relatives strive to tear the PC owner away from their favorite technology - to play alone, others do not mind watching a movie. Of course, such problems can be solved by purchasing computers for each family member, but there are other ways out.
I think many have appreciated the benefits of a high-quality picture transmitted to a TV by a computer, successfully use this technique together - for video games on a large screen, or watching feature films, and also found out for themselves the dubious convenience of using a TV in everyday work on a PC. Some even decided to use the LCD panel as an additional monitor. Well, let's get busy.
For us to be successful, the graphics card must be able to handle multiple devices. Read the instructions, or inspect its panel - this possibility is indicated by the presence of several connectors:
- VGA. The oldest analog interface standard, subject to video signal degradation due to interference, should be abandoned in favor of digital interfaces if possible.
- HDMI. New generation digital interface. Both video signal and multi-channel audio are transmitted.
- DP (Display port). The most modern port. It has the ability to transmit both high-resolution video (up to 3840 x 2400) and audio signals.
- DVI. The digital interface that replaced VGA. The signal quality is much higher, but there is the same drawback as its predecessor - there is no sound transmission channel.
We chose the desired interface - connect the cable, select the input to which you connected in the TV menu and take care of the settings on the computer.
Right-click on an empty spot on the desktop, in the menu that opens, we need the “Screen Resolution” item. (Try to guess that this is where the work with multiple monitors is configured ...)
As you can see, the system has not yet identified our TV.
We press the “find” button and we immediately see that the computer now has two monitors:
Now we select our TV and set its resolution to 1920 × 1080 and higher, if your equipment supports such resolutions:
In the window that opens, on the “Monitor” tab, select the maximum supported frequency, this will speed up the update and reduce screen flicker:
The monitor connection setup is now complete. Now we need to decide how the image will be displayed. There are four different options available on the menu:
- the first will allow you to display a copy of the image on the TV
- the second extends the desktop to both devices, the mouse moves over them as if the desktop is solid
- the third and fourth options display the image on one of the devices
It is worth recommending to stop at option number two - “expand these screens”. In this case, you can easily transfer the video player window to the TV screen. Although the desktop is shared, in full-screen mode, the video will only be displayed on the screen where the player window is located.
This inclusion option will allow you to simultaneously watch movies and work on a computer behind a monitor. Do not forget to only select the main device, on the desktop of which the system bar with the “start” button will be displayed:
However, I do not think that this device will be a TV.
By the way, you can quickly switch from one image output mode to another using the Win / P key combination - after pressing them, the quick switching menu will be displayed on the main screen:
Here you will see exactly the same four options, but with slightly different names. You can even select one of them blindly (suddenly your TV is selected as the main one, and you turned it off) - using the left / right arrows and the “Enter” key.
Modern plasma TVs have little in common with the rectangular units with domed screens that used to be in every home. They boast outstanding technical performance, high image clarity and a range of additional features. Now connecting a TV to a computer is no longer something surprising or fantastic.
Many owners of PCs and laptops 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?" We'll 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 pushing 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, consider the main advantages of such a "tandem":
- Computer games on the big screen.
- Watching movies and videos.
- Skype communication.
- 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, photos, etc. And sometimes you really want to try it all in a "new format" - display it on the big screen . And for this you need to understand how to connect a computer to a TV.
Features of connecting different equipment
In general, the possibility of "combining" different techniques appeared a long time ago. Even old TVs and not very modern PCs can be connected to each other. True, this requires 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 used to try to connect a TV to a computer via VGA.
Modern audio and video equipment is much more technological and advanced, and therefore 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.
With the VGA port, in some cases there are difficulties, because it is often absent altogether on modern video cards. Many laptop models, like 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 positions, many users continue to use them for work. Most still have old equipment in good condition. And a lot of people are now digitizing video cassettes, watching records from old hard drives, etc.
The VGA interface is considered obsolete. It provides image transmission with 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 a computer and perform further configuration.
The procedure is carried out in several stages:
- The power of both devices (TV and computer) turns off.
- The cable is connected to the appropriate connectors.
- Devices turn on.
- Settings are being made in Windows.
It is easy to guess that in itself, connecting a TV to a computer does not cause any particular difficulties. Much more questions arise when it comes directly to setting up Windows. Without this, it is impossible to achieve a quality connection.
If the image is not transmitted to the TV or there are any problems and interference, then, most likely, errors were made in the settings. Particular attention should be paid to the display modes - "only to the TV" or "display and TV at the same time."
If you need to connect a TV to a VGA computer, you must make the following settings in the operating system:
- On the desktop, in the context menu (right mouse button), select "Screen resolution".
- Open the Display panel.
- Select the required display mode.
- Apply and save.
In some cases, you will additionally need to make a small 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, it is worth using various adapters. You can find the necessary interfaces on the back of the system unit, as well as on the back and sides of the TV and laptop.
Why is it better to connect a TV to a computer via HDMI?
Advanced technology has gained immense popularity both among specialists and ordinary users. Currently, modern models of LED TVs 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 transfer signals in digital quality. Corresponding adapters are available on the market, so these ports are almost identical in their ability to perform the task.
What should I pay attention to when connecting a computer to an HDMI TV?
- Display and TV resolution.
- Correct connection.
- settings in the operating system.
Usually, there are no special problems 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, then the latter will take over the functions of the primary display. If both the main monitor and the LCD TV are connected at this moment, then you need to adjust the display modes.
Some modern televisions have an actual resolution of 1400 x 1900 pixels, while the video cards of personal computers and laptops are set to "standard" 1280 x 720 or 1920 x 1080 pixels. With such a mismatch, often the TV gives out just a black screen. To correct the situation, it is necessary to set the exact parameters in accordance with the characteristics of the equipment.
In the event that this is the first time you are trying to figure out how to connect a TV to a computer, experts recommend that you also connect the main monitor (for example, via DVI or VGA) or use a laptop. Then it becomes possible to change the settings of the operating system or video card drivers.
HDMI connection process
To perform 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 stages of connection:
- Direct connection of devices (in the off state).
- Turning on the computer and TV (waiting for full download).
- Switching on the TV to the appropriate HDMI port (source - port).
- Setting up a connection in Windows OS.
As a rule, the default is set to display only on the second display, i.e. the TV becomes the main one. Due to the resolution mismatch, the image may not be transmitted. To understand how to connect a computer to a TV, you need to "dig" in the settings.
It is best to select "Multiple monitors" in the "Screen" menu, and also set the "Duplicate screens" option. After that, everything should work, and the Windows desktop will be displayed on the TV.
To get the best image quality, you need to accurately determine its resolution. Usually, in this matter, the focus is on him (otherwise, why did TV need to be connected at all?). By correctly connecting the TV to the computer via HDMI, you can freely work with the new screen.
Audio problems
Displaying a picture on a TV screen is only half the battle. There are a lot of questions about sound settings. As a rule, with such an approach, you want to use all the available features, 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 regular 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, it can be quite difficult to achieve the correct sound through the TV speakers. Common problems when connecting the mentioned device are:
- Complete lack of sound.
- Various disturbances.
- 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 customization features
When the TV is connected to a computer, sound is also transmitted through the used HDMI cable. As in the case of image settings, 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-fledged connection. And for this, you do not need to purchase additional cords, etc. Since HDMI, along with USB, is considered a widespread world standard, this leads to the fact that many types of equipment support it.
Thus, when making a connection, an HDMI cable performs two main tasks:
- High definition image transmission.
- Surround stereo sound transmission.
Versatility is also evident in the settings. With some models of computers and TVs, there is no such need at all. In other situations, you will need to change something in the settings of the operating system. It is almost never necessary to install additional software, except perhaps to simplify management.
Primary connection of two devices
When we work with a particular technique, we try to take advantage of all the possibilities. When connecting a TV to a computer with HDMI, we encounter 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 speakers of a laptop or PC speakers. What to do in such situations?
You need to set up the audio signal transmission. Let's start with the Taskbar:
- The Hardware and Sound menu in the Control Panel.
- The "Manage Sound Resources" tab that opens.
- Item AMD HDMI Output.
Finding all this will not be difficult, because all the settings are literally on the surface, so the whole procedure will take a couple of minutes at most.
There are several aspects to which particular attention should be paid. If the video card of a computer or laptop supports sound 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 must be understood 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 observed. What should be done if there are still connection problems?
- Check the health of the equipment.
- Update drivers (primarily sound).
- Try other settings options.
Not all users know about all the main 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 are the most common problems?
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 for the presence of this driver, you should 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 game controllers" tab. Next, you should carefully study the proposed list and find there "High Definition Audio capable device", which has already been mentioned above. If this item is present, then the computer is capable of transmitting audio through the HDMI cable.
What should be done if the corresponding driver is not available?
In this case, you will need to download and install it. The website of the manufacturer of a laptop or a specific sound card should have distribution kits for installation. In addition, in some cases, the OS itself is able to determine the missing drivers for correct operation.
Another option for configuring the system is to check the available playback devices. Finding them is easy - 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 of which is labeled "Playback devices".
This is where the connected TV should appear, along with other options (speakers and headphones). It remains only to 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 features, including connecting a TV to a computer via wireless networks.
What is required 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 TV adapter connected via a USB port.
The advantages of such a connection are obvious:
- Easy connection without 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, additional software is required - a special utility that comes with the TV. It would be useful 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 straightforward. Most often, a special folder is created on the hard disk of the PC, 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, it becomes possible to freely view various files.
General conclusion
If there is a need to combine two devices, you need to choose 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.
Synchronization with a PC will significantly expand the functionality of the TV. Therefore, it is not surprising that all users want to know how to connect a computer to a TV? Note that there are a huge number of different methods, each of which we will carefully analyze. A lot will depend on the TV model. Old appliances are equipped with connectors that are not on computers. Because of this, certain difficulties may arise.
A PC is connected to an LG TV or equipment from any other manufacturer using special cables. There are also ways to wirelessly sync. However, not all TVs are equipped with a built-in Wi-Fi module, which is necessary for a wireless Internet connection.
Why is it needed
Each user must independently determine whether it makes sense to connect a TV to a computer? For example, if you only watch pre-tuned channels, then connecting a PC to a TV is unlikely to be useful to you. To a greater extent, such synchronization will be of interest to users who want to watch the latest cinema, TV shows and other content.
Outputting an image from a computer to a TV will definitely expand the functionality of the equipment. After setting up such a connection, you will be able to:
- play video games on the big screen TV;
- watch movies, series, videos;
- communicate with friends and acquaintances via Skype;
- make presentations.
The resolution and saturation of the color palette of modern Samsung, Sony, LG TVs is much higher than that of an inexpensive computer monitor. Therefore, the synchronization of technology will allow you to watch new movies in excellent quality. This is especially true if you purchased a device without a built-in Wi-Fi module and Smart TV support.
Setting up a TV as a monitor is much easier than it might seem at first glance. Each user will cope with this task. It is enough to decide on the method of synchronization, as well as to acquire the necessary cord. It is possible that you already have the necessary cables at home.
Connection options
How to connect a computer to a TV? Conventionally, all existing methods can be divided into two large groups - wireless and using a cable. Choosing one or another method, start from the technique used. See which computer and TV inputs can be used for synchronization.
First, let's briefly list the methods that ensure the broadcast of images on a large TV screen without loss of quality. If none of these options work for you, then less popular connectors can be used.
As mentioned earlier, it is likely that you will have to additionally purchase a specific cable. The cost of such wires is minimal. If you plan to use adapters, then you should go to an electronics store. This scenario is relevant in cases where an old PC or TV is used.
All kinds of additional coverings of cords are advertising tinsel. This aspect does not affect the quality of the transmitted image in any way. Think carefully about how long the cable should be for your convenience. It is important not only to set up the connection, but also to maintain the aesthetic appearance of the room.
The easiest way to connect an LCD TV to a computer is with an HDMI cable. Firstly, absolutely all modern technology is equipped with this interface. Secondly, it carries out simultaneous transmission of audio signal and video signal. Alternatively, you can use one of the following options:
- S-video;
All of these connectors are obsolete. Therefore, they should only be used if you are using old technology. HDMI remains the priority.
Let's say a few words about wireless synchronization. This option assumes that your TV will have a built-in Wi-Fi module. Mostly they are equipped with models with support for Smart TV. Today you can buy an adapter for wireless Internet connection and insert it into a regular TV.
HDMI
An HDMI cable is not included in the basic package of a computer or TV. Therefore, this cable will have to be purchased separately. In electronics supermarkets, they are presented in a wide range. Wire length from 1 to 20 meters. With the choice of problems will not arise. When the cord is purchased, find the appropriate ports on the TV and PC.
How to connect a TV through a computer via HDMI? Follow the step by step instructions:
Older computers do not have an HDMI connector. The problem is solved by buying an adapter. For example, a USB to HDMI adapter will work for you.
Mostly, the default settings are set to display the picture only on the second display, which is the TV screen. Due to the difference in resolution between TV and PC, the picture may not be displayed correctly. Therefore, you need to open the settings of the Windows operating system and make changes to some parameters.
Open the menu "Screen", and select the item "Multiple Monitors". Be sure to activate the display duplication function. After that, the problem should disappear. The computer desktop appears on the TV screen.
How to improve picture quality? Go to personalization and then change the resolution. However, it is possible that the selection of resolution will be performed automatically. If not, then set your TV's resolution. The image quality will improve noticeably.
WiFi
Wireless networks can also be thought of as a way to connect a TV to a computer. What is needed for such synchronization? First, you need to study the specifications of the LCD or plasma TV. Unfortunately, only modern models support data transfer by setting up a Wi-Fi connection. If your model does not support wireless Internet connection, then buy a special adapter. It connects via USB.
Connecting a PC to a TV wirelessly has obvious advantages:
- Internet access;
- viewing content stored on the hard drive of the PC;
- simple connection process;
- free arrangement of devices;
- no wires.
To set up such synchronization, you need to use a special utility. The software comes with the TV. If the disk with the software was not included in the basic package, then download the program from the official website of the manufacturer of the equipment.
The main function of the software is to quickly connect a PC to a TV via a home Wi-Fi network. The interface of the utility is extremely simple and clear. On the computer's hard drive, you will need to create a special directory through which content for TV will be sent.
Many users solve similar problems through another router. A single wireless network will cover absolutely all devices, including the TV. Therefore, all kinds of files can be played on the big screen.
S-video
Another way to sync TV and PC is to use the S-Video interface. This option is good because absolutely all equipment is equipped with such a connector. An exception may be computers with extremely old GPU modules. Another strength of this synchronization is simplicity. The user just needs to connect the S-Video connectors on the PC and TV with a cable
Before connecting the TV to the computer via the S-Video interface, you need to turn off the equipment. One end of the cable plugs into the connector on the PC video card - a round black socket. The other plug is connected to the corresponding TV input, it is located mainly on the rear panel of the device.
Turn on the TV first, and then the PC. During the loading of the operating system, the TV screen will flash - this is a sign that a new signal source has been identified. Now the user's task is to configure the GPU module. Right-click on the desktop, select from the context menu "Properties", go to section "Options".
Open item "Additionally". In the dialog box that appears, next to the name of the GPU, check the box "Clone". When the setting is applied, click on the "Display" section. From the list that opens, you need to select the name of the TV. Take the TV remote control, and set the appropriate signal source. In our case, this is the S-Video connector. When the image appears on the big screen, you can proceed to its settings. Now you know how to connect a computer or laptop to an old TV.
Miracast
Many users confuse this technology with DLNA. In fact, it differs in that it greatly simplifies the playback of not only files that are stored on a PC hard drive, but also allows you to play content online. For example, you can turn on your favorite movie or a new episode of a popular show using a regular browser.
To use Miracast technology, you need a powerful computer. This is because it is a resource intensive application. Therefore, synchronization via Miracast is relevant among owners of PCs, laptops and tablets with powerful hardware stuffing.
How to set up a TV if it supports the technology in question optionally? You need to purchase a special adapter. It connects to the device via HDMI interface. Wireless monitor technology is characterized by maximum ease of use. The image displayed on the big screen will be broadcast according to a special algorithm. The image is mirrored via Wi-Fi to a large TV screen. 
The user does not need to connect the TV to one of the local networks using a router. With the help of routers, a mini-network is created, which greatly simplifies synchronization with a PC. You will need a program to connect a wireless monitor - the Wireless Display utility. When the add-on is installed, you can start broadcasting.
Make sure that the Miracast option is enabled in the TV menu. You can enable this feature in the settings. Open the "Networks" tab, and then go to the "Intel WiDi" subsection.
VGA and DVI
How to connect an old TV to a computer? DVI and VGA connectors are ideal for this task. Let's consider each of them to determine the features and rules of such synchronization. Let's start with VGA. Almost all equipment is equipped with this interface. An exception can be considered inexpensive laptops and netbooks. The VGA connector is the standard and also the oldest method of analog TV connection from system units.
Why is VGA considered obsolete, and what exactly does it lose to HDMI? First, image transmission is carried out through analog signals. Secondly, by today's standards, the speed of information transfer is extremely low.
If the equipment you use is equipped with this interface, and you also have a VGA cable, then there should be no problems with connection and subsequent configuration. Step-by-step instruction:
- Insert the wire plugs into the matching sockets.
- Turn on the tech.
- Select VGA interface as the main signal source.
- Make the appropriate settings in the Windows operating system.
The connection process itself should not cause any difficulties. Mostly, users have questions regarding the configuration. If you ignore this stage, then the user will absolutely not be able to achieve the broadcast of a high-quality image.
If the picture is not broadcast on the TV screen, and certain problems, interference, defects are also visible, then the user has set incorrect settings. Particular attention should be paid to the image transmission mode. There are two modes - "Only on TV", "Display and TV at the same time".
Before connecting the TV to a PC using the VGA interface, you need to set up the operating system accordingly:
- On the free space of the desktop, right-click.
- Select a section from the context menu "Screen resolution".
- Open the menu "Screen".
- Select one of the available image translation modes.
- Save your changes.
As you can see, connecting a PC and TV via VGA is as simple as possible. The main thing is to set the necessary parameters.
The DVI interface is considered more modern and advanced when compared to VGA. First, both analog and digital signals are transmitted. Secondly, there is a gradation of the interface into groups with a specific, narrow focus:
- DVI-D - designed for digital connection;
- DVI-A - suitable for analog type signals;
- DVI-I is a universal option.
As for the connection process itself, it is carried out in the same way as in the case of other interfaces. First, the user connects the cable plugs to the TV and computer connectors, and then selects the appropriate signal source.
Frequent problems
If you decide to connect a laptop or PC via HDMI, you first need to check for an audio driver. Without High Definition Audio support, there will be no sound signal. To check if this driver is installed, open "Device Manager". Select tab "Sound devices". In the list that appears, find a device that supports "High Definition Audio". If there is no such line, then it will absolutely not work to adjust the sound when connected via HDMI.
What to do if the required driver is not available? The answer is very simple - you need to download it to your computer or laptop, and then install it. Downloading is carried out from the official website of the manufacturer. Enter the name of your sound card in the search field, after which you will be offered a distribution kit for installation. In some situations, the operating system is able to independently detect the missing drivers, and then download and install them.
Some users set up the operating system in a different way. To find available playback devices, open the system tray - the lower right corner. Right click on the sound playback icon. In the context menu that opens, select the item "Playback Devices". Here the connected TV should be displayed along with other devices: speakers, headset, headphones. The user needs to select the source of sound playback, and then click on the button "OK".
Bringing the image to the big screen is half the battle. Mostly users face problems related to sound. It is clear that no one wants to watch a new movie with sound playback through the speakers of a PC or laptop. Modern TV models are equipped with powerful speakers with the clearest and most natural sound. Some even buy additional audio systems to increase the level of immersion in viewing.
In many situations, to achieve high-quality sound, i.e. playing sound through the TV speakers can be extremely difficult. Common problems that almost all users face after synchronizing the TV and computer:
- there is no sound at all;
- excessive noise or other interference is heard;
- audio signal delay;
- volume problems.
Please note that there are several problems. Therefore, the initial task of the user is to determine what exactly the problem is.
In the process of using a certain technique, you are trying to use all its additional features. It is reasonable. For example, when connecting a computer to a TV via an HDMI cable, we expect a comfortable viewing experience, but it is not always possible to avoid problems. With image settings, difficulties arise quite rarely. Since on modern devices automatic selection of resolution and other parameters is carried out.
Sound is the most common problem. What should the user do to make the TV start playing sound correctly? You need to start by setting up audio signal transmission in the "Taskbar":
- open "Control Panel".
- Go to menu "Hardware and Sound".
- Go to the tab "Sound Resource Management".
- Select an item AMD HDMI Output.
The last point may be called a little differently. It all depends on which company produced the iron. Finding the necessary parameters to fine-tune is not difficult. The whole process takes only 2-3 minutes. Just follow the instructions.
Please note that if the video card of the PC supports audio transmission, the user can select the item in the settings "Digital Audio S/PDIF". If this is not done, the audio signal will be transmitted through the motherboard, which is connected to the GPU module.
Note.
Watching movies or videos, playing games, working with documents on a large screen is much easier, especially considering the fact that lately LCD TVs have become increasingly popular. Connection does not require special knowledge or skills, all you need is to check the availability of outputs that your computer and TV have and choose the most suitable option.
Preparing to connect
The first and most important tool that is required for connection is a cable. There are several of the most popular connectors that are used to transmit image and sound. The most common of them are:
Connection actions
All connection operations consist in choosing a cable, connecting the cable to the connectors and setting up devices. The most important point is setting up a PC or laptop.
Computer settings
When connecting the cord to the TV and computer, you must:
- right-click on the desktop;
- in the menu that appears, select "Screen resolution" ("Properties" - "Settings" for Windows XP);
- to display the image on two screens, in the “Multiple screens” option, select the “Duplicate these screens” item.
Since the image is displayed with the same resolution, the same monitor and TV formats are important in order to get the “correct” picture.

Connecting via DVI
To connect via DVI, you can also use a VGA-DVI adapter if any device does not have a DVI connector. It should be noted that DVI does not transmit audio; other connectors must be used to transmit audio. In other parameters, the connection setting is identical to the HDMI connection setting.
Connecting via S-Video
If the TV does not have DVI, HDMI or VGA outputs, then the S-Video option remains, an output that is present on many personal computers.

There are various adapters (converters) that allow you to transfer an image using various outputs, for example, VGA-HDMI. Unfortunately, the price of such devices will not suit many users.
Is the input analog or digital?
These connectors assume that the signal is not encoded into analog. As a rule, they connect via a digital connector if there are digital connectors and cables, and via an analog one if there is no hdmi or dvi.
