Connecting LCD TV to PC. Connecting the TV to computer equipment

When the computer screen is not enough to meet all the needs, then the good old friend - the TV comes to the rescue. Well, not very old, "Dawn" is not suitable for these functions, but modern plasma panels are quite friendly with a computer. And then it will be possible to launch a game, favorite movie or music (although why would a big screen be needed for music?) on a wide plasma.

It seems that it is very simple, but in the process, many encounter difficulties, and on the Internet they ask Google how to connect a TV to a computer. Fortunately, the search engine knows the answers to all questions. And this problem also has several solutions.

• 1 HDMI
• 2 DVI cables
• 3 VGA cable
• 4 RJ45 - network connector

HDMI

HDMI allows you to better connect your PC to your TV. Through this cord, you can transfer a high-quality picture, and even sound. The TV and the panel of the system unit must have a special connector with a height of 4.5 mm and a width of 14 mm. To make the connection, you need a cable with an HDMI plug on each end.

Some models of video cards are equipped with a mini-HDMI input, so you will also need a special adapter from the standard version to the mini. This adapter should come with the video card, so you should look for it in old boxes. If it is not there, then the purchase will not be a problem, any computer store or point on the market sells such a product at a low price.

By the way, about the price. The materials, color and other features of the cord and adapter do not affect the quality of the image transmission, but only the cost of the product. Consultants can convince you otherwise, but this is not so. Therefore, it is not worth buying a piece of cord for several hundred "evergreens", cheap options for 5-15 dollars will also perform their function perfectly. Digital data will go through the cable, which is not affected by various interferences.

How to connect a TV:

DVI cables

First, you need to remember that DVI connectors, and accordingly cables, are different.

Therefore, you should find out which specific type is needed, and only then buy it. Each option has its own features and characteristics:

• DVI-D. This type transmits digital signals from the unit's video card to the TV. Data is transferred quickly and with high quality;
• DVI-I. Such a cable is truly universal, because it provides both analog and digital transmission of image and sound. Choosing this option will be the best solution, although it costs a little more;
• DVI-A. Most experts do not advise buying this type of cable. Its peculiarity is that the data is processed from digital to analog, and only then go to the screen and to the TV speakers. These processes greatly affect the image quality.

VGA cable

The problem of connecting a TV to a computer can be solved using a VGA cable. The connector for this cable is standard and is present in all video cards for transmitting an analog signal. If there is a connector for it on the TV, then the connection will not be any problem. To do this, you need the actual VGA cable and audio cable.

But before you start using this method, you need to check if the TV supports high resolution. The fact is that many TV models via a VGA cable can only receive low-quality signals. If everything is in order and high resolution is supported, then you can start connecting:

• Disconnect the equipment from the mains;
• Connect the VGA cable to the corresponding inputs on the TV and computer;
• The audio output of the PC must be connected to the audio-in socket on the TV. This requires a special audio cable;
• Turn on TV and PC;
• Make settings for the computer and TV (similar to the settings from the HDMI connection);

RJ45 - network connector

To make such a connection, you need to match the TV to two parameters:

• He must have a media player (to put it simply, he must be able to play music, videos and images from a flash drive);
• It must support DLNA technology and its unit must contain an RJ45 network connector;

DLNA is such a special technology that provides for the exchange of information between the TV and other devices in real time. Thanks to this system, it is possible to play files directly from the hard drive without transferring them to other media. You can find out if there is such a function in a particular TV model from the instructions for it or on the manufacturer's website.

To connect a TV to a computer, you need:

• Make a physical connection;
• Download and install a special program (it is free);

The first stage involves connecting directly, or through a router. It is not advised to use a router, because then it has a large load, which will lead to loss of performance. In order to connect without a router, you need a "Crossover" twisted pair cable. Crimping at the cord must be crossed. You will also need to make changes to the settings for the IP protocol.

The following configuration will do:

If the computer contains two network cards, then only the one that connects to the TV needs to be configured. You also need to download and install the Home Media Server application. After that, you need to change certain settings (when the cable is already connected and the equipment is turned on):

To view files, you need to turn on the equipment, the Home Media Service program is running, and select Ethernet (Lan) as the source of media files. This will open the explorer, which will allow you to view the required files using the remote.

Connecting the TV to computer equipment

When connecting a TV to a computer, you must first implement a hardware connection using the appropriate cables and connectors, and then configure the necessary settings. The settings themselves may differ from the operating system used and the video card model on the computer.

It must be said that such a connection of a TV to a computer or laptop is necessary to use the screen of a television receiver with a large diagonal as a monitor. It is much more pleasant to watch movies, photos or play games. But all this is true for modern models of HD Ready TV receivers with a screen resolution of 1920x1080 or 1366x768. When using screens with a lower resolution, which is found on older TVs, you may not get a benefit in video quality. Or there may be a situation where the necessary connectors are not available to transfer high-definition video from a computer to a TV. But all modern models and TVs and video cards can be interconnected to view Full HD video on the TV screen.

TV connectors

The transmission of a high-resolution image is associated with the use of a video signal in digital form and its subsequent processing. HDMI and DVI interfaces are used for digital video transmission. It is with the connectors and cables of these two interfaces that the connection of the TV to the computer is connected today. It must be said that there are three types of DVI digital, analog and combined. That is, in order to transmit a Full HD digital signal through it, you need to select a video card with a digital output (indicated by the additional letter D) or a combined one and use the appropriate cable.

HDMI is considered the preferred connection option, as it also transmits sound along with video. When connecting via DVI, you may need to additionally connect the audio signal via a separate cable. In order for the video card to output sound in some models, you will need to connect the S / PDIF connectors inside the computer system unit, the connection cable is included in the video card kit. Then it is even possible that the sound will be on the DVI output, and using the DVI-HDMI adapter and further on the HDMI-HDMI cable to the TV, you can get video and sound from one DVI connector. An HDMI cable is even better in that it can be very long (more than 10 meters). And when using a DVI-DVI cable, it may be necessary to install intermediate amplifiers (which no one does) if the length exceeds 5 meters, otherwise interference will occur.

To connect a computer, the TV may have a separate HDMI input, despite the fact that usually there are several such connectors on the TV set. You need to read the instructions to determine the correct input.

If you are using a home theater to play sound or another audio system, you can send a signal from the computer via HDMI to the receiver, and from the receiver to the TV also via HDMI.

All other methods of transmitting video from a computer use an analog signal form and are not capable of transmitting HD video. They are used when it is not possible to connect via HDMI or DVI.

1. 1) VGA (D-sub). One of the main connectors in modern LCD TVs. Used to connect a computer. Has 15 contacts. Capable of transmitting a signal with a resolution of 1280x1024 pixels.
2. 2) Component. Represents three "tulips" of different colors: green, blue, red. The color component is transmitted through two of them, and the luminance signal passes through the third. On devices, it is designated as Y Pb Pr. The performance of this connection is better than A/V and S-video.
3. 3) Scart. This is a large connector with 21 pins. It has different specifications, so it can transmit different signals, depending on what manufacturers have connected inside the connector. Can transmit good quality video (standard definition) and audio.
4. 4) S-video. It has also been used in video technology for a long time. It may no longer be on modern TVs. The transmission of color and brightness goes through different wires, so this connector is better than ordinary tulips. Transmission of video signal only, sound is connected by a separate cable. There may be 4 or 7 pins in the connector.
5. 5) Composite (A/V). These are ordinary "tulips" (RCA). Have been in use for a long time. It is worse than component in that both brightness and color signals are transmitted over one cable, so interference occurs. They can stand on DVD, game consoles, etc. Both video and sound are transmitted.

Usually, after a correct connection, the picture from the computer immediately appears on the TV screen. Sometimes you need to adjust the resolution or, if there is no image at all, adjust the outputs and inputs correctly. Before setting up, it is recommended to download and install the latest drivers for your video card and computer sound card.

The most common are the following models of video cards:

• Based on the NVIDIA platform. Drivers are available at NVidia.ru
• Based on the ATI platform. Drivers are available at ATI.ru
• Based on the Intel Extreme Graphics platform. Drivers are available on Intel.com

After connecting and turning on the network on both devices, Windows should display a connection message and ask how you are going to use the secondary screen. There are three options:

1. 1 Use an external display as the main display.
2. 2 Extend the workspace to another screen, both displays being used.
3. 3 Use screen connections as a clone, i.e. the image on the two displays is the same.

It is preferable to use the connected TV in clone mode, so it is easier to set up and control it.

If the operating system itself has not defined a new connection, then you can go to the display settings menu yourself. Through Start-Control Panel-Screen you will be taken to the screen settings menu.

In this menu, you need to configure the parameters of the connected display as you need.

For more complete image settings (resolution, frame rate, aspect ratio, color gamut), you may need to go to the video card settings.

For ATI video cards, this is “ATI Catalyst Control Center”:

For NVidia graphics cards, this is the “NVIDIA Control Panel”:

To enter the video card settings, you need to right-click on an empty spot on the desktop and select the desired item corresponding to your video card in the menu that appears.

How to connect a computer to a TV via HDMI?

Most modern LCD TVs are equipped with various interfaces for connecting other devices. HDMI interface is available on almost every LCD panel. Thanks to the HDMI connector, you can connect a DVD player, satellite receiver, computer and various mobile devices, such as a tablet, smartphone or mini-computer, to the TV. But most users do not know how to connect a computer to a TV via HDMI. If you are faced with the problem of “correctly” connecting a computer to a TV, then this article will help you solve it.

The first step is to find out if there is an HDMI connector in the system unit of your computer. For connecting two devices via HDMI, in our case a computer and a TV, requires an HDMI interface in each device. This connector is located in the video card of the computer and allows you to transmit video and sound over a single cable. Thus, unlike VGA, HDMI does not have problems with sound transmission. The HDMI connector on the video card looks like this:

The interface is always located on the back of the system unit. As for the HDMI connector on the TV, it can be located both on the back of the case and on the side. Moreover, the TV may have several connectors that are designed to connect various devices.

The scheme for connecting a computer to a TV is as follows: turn off both devices, insert one end of the cable into the TV, and the other into the HDMI connector on the computer.

Please note that you will need to purchase an HDMI cable from the store, since such a cable is not supplied with the TV. The HDMI connector looks like this:

After connecting the TV to the computer, turn on the LCD panel, open the settings and set the HDMI input as a signal source.

Then we turn on the computer and wait for the system to boot. As a rule, the image on the TV should appear at this very moment. If there is no image, then right-click on the desktop after loading the system and select the “Screen Resolution” tab. In the "Screen" line, select the LCD panel, click "Apply" and "OK".

In this way, you can connect a computer to a TV via HDMI on Windows 7/8/10. But what if your video card does not have an HDMI interface? As a rule, every video card has a DVI connector. On sale there are special cables and adapters of the DVI-HDMI type, with which you can connect the LCD TV to the computer system unit.

If the image on the TV is of poor quality or cropped, then in the video card settings you can always set the necessary resolution and image quality values. When buying a cable, you should not save money, because often there are problems with cheap HDMI cables: sound is not transmitted, the picture quality deteriorates, data transfer stops.

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.

www.amazon.com

• 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.

- local area network (LAN, local area network; English Local Area Network, LAN) - a computer network that usually covers a relatively small area or a small group of buildings (home, office, company, institute).

VGA

-(English Video Graphics Array) - monitor standard and video adapters. Released by IBM in 1987. Designed for video transmission only. It is impossible to broadcast an audio signal according to the Video Graphics Array standard. An additional audio cable is required to play audio when connecting a computer to a TV via VGA connectors.

HDMI

-High-Definition Multimedia Interface (HDMI) is a high-definition multimedia interface that allows high-definition digital video and copy-protected multi-channel digital audio to be transmitted. The HDMI connector provides a digital DVI connection for multiple devices using the appropriate cables. The main difference between HDMI and DVI is that the HDMI connector is smaller and also supports the transmission of multi-channel digital audio signals. It is a replacement for analog connection standards such as SCART or RCA.

To output an image from a computer to a TV via VGA, DVI (only with an adapter), HDMI connectors - software installation is NOT REQUIRED! We recommend that you perform all manipulations with cables when connecting a computer to a TV with de-energized equipment!

DVI

-Digital Visual Interface, abbr. DVI (Digital Video Interface) is an interface standard and a corresponding connector designed to transmit video images to digital display devices such as LCD monitors and projectors. Developed by the Digital Display Working Group. Almost all TVs DO NOT HAVE a DVI interface.

We connect the TV to the computer via a LAN cable.

the connection is made between the TV and the computer directly or through a router (through a router is preferable and easier). After a physical connection with a cable, special software is installed on the computer to "share" content within your home network, the TV detects these files and you use the remote control to play movies, music or view photos from the computer on the TV screen. Each manufacturer recommends its own program for connecting a TV to a computer and "sharing" files, but there are also universal programs that are suitable for most TV models, for example, Home Media Server, which can be downloaded from here. To connect a computer to a TV via a LAN interface, network cables are used - patch cords. The length of pre-compressed and tested patch cords ranges from 0.5m to 100m. In our computer store, patch cords from 0.5m to 30m are available at a price of 20r to 320r. To connect a computer to a TV via a LAN interface, you must have certain skills in working with a PC, the other three methods are much simpler and do not require any special skills other than attentiveness and common sense.

We connect the TV to the computer via a VGA cable.

The connection is made via a VGA cable with 15-pin connectors on both ends of the cable. A variant of the VGA-DVI cable is possible, on one side of such a cable there will be a trapezoidal VGA connector, and on the other a rectangular DVI.

Cables VGA-HDMI, VGA-USB, VGA-MiniUSB - DO NOT EXIST!

Adapters VGA-HDMI, VGA-USB, VGA-MiniUSB - DO NOT EXIST!

When connecting a TV to a computer via a VGA cable, keep in mind that the VGA standard transmits only images without sound. To transmit an audio signal, in this case, you will have to use another

We connect the TV to the computer via a DVI cable.

The connection is made using a DVI cable. The DVI standard provides high quality digital signal transmission. The DVI interface transmits only the image without sound. To transmit an audio signal, in this case, you will have to use another cable audio jack 3.5mm - audio jack 3.5mm, 1.5m

Attention! TV sets of mass series are not equipped with DVI connectors!

If your video card does not have VGA or HDMI connectors and only DVI, use adapters: DVI-VGA, DVI-HDMI or special cables with DVI-VGA, DVI-HDMI connectors.

We connect the TV to the computer via an HDMI cable.

The connection is the most preferred among the rest. An HDMI cable with HDMI connectors at both ends will provide excellent picture and high-quality sound, the video signal is transmitted in Full HD quality and higher, simultaneously with a multi-channel audio stream! All modern TVs and video cards of computers and laptops are equipped with HDMI connectors. When buying a TV, computer or laptop, make sure you have an HDMI connector. Do not purchase obsolete or low-functional equipment! I answer all questions in detail.
Friends! Everything you do on your computer, watch movies, cartoons, chat on Skype, play games, view photos, slides or Internet pages in a browser, all this will be shown on your TV screen if the TV is connected to the computer via an HDMI cable. Now, almost every TV has an HDMI input, and most of the video cards produced have an HDMI output.
The HDMI interface was invented in order to connect two high-tech digital devices (they are undoubtedly your computer and TV) and transfer information from device to device without loss of quality. Such transmitted information can be an image and multi-channel high-quality sound. If you have a movie or cartoon on your computer, in any HD, Blu-ray or AVI, MOV, MPG, MP4 format, then you can watch all this on your TV. There are slides or pictures, please see. I'm not talking about games, because I'm not a supporter of them, they take a lot of time from young people, which can be spent on studying. We connect the TV to the computer via HDMI with a second monitor To connect the computer to the TV, we will use an HDMI cable, it looks like this and can be up to 20 meters long, choose the cable of the length you need.

For example, let's take a Samsung TV, not quite a new 4 series (LED type), bought a few years ago, but it already has two connectors for connecting HDMI devices.

The computer that we will use to connect to the TV was also purchased about three years ago, it has an Nvidia video card installed and also with an HDMI connector.

As I said, our TV has two HDMI connectors. On the TV turned off, connect the HDMI cable to the HDMI 2 connector,

We connect the reverse end of the cable to the HDMI connector of the video card of a desktop computer. The computer, in turn, is already connected to the monitor (also Samsung SyncMaster 971P) with a DVI cable.

We turn on the computer and TV. There may not be an image on the TV right away, instead we see such a message “Cable is not connected” “Check the cable connection and source parameter” or “Weak signal or no signal”

On Samsung TVs, to display a list of all available video sources, you need to press the Source button on the remote control (Source).

A menu appears on the TV, in this menu, using the remote control, select the HDMI 2 connector,

Now, on our TV, an exact copy of the desktop of our computer should appear. But again there is nothing, the same error appears on a black screen. So we go to the "Screen Resolution" settings. Right-click on the desktop and select Screen Resolution.

As you can see in the window that appears, we have the second (2) Samsung SyncMaster 971P monitor set as the main screen, and in the “Multiple screens” parameter we have set “Display the desktop only on 2 monitors”, which is why the image is present only on the screen of the computer monitor, but it's not on TV

We bring everything in this window to this state. Choose an option
Multiple screens: "Duplicate these screens"
In the "Screen" parameter, "Multiple monitors" is automatically set, click Apply and OK.

The desktop of our computer appears on the TV.

The resolution of our small Samsung TV is 1366 x 768. If your computer monitor supports this resolution, then it will be set to the same resolution of 1366 x 768 automatically. If not, then either the TV or the monitor will have the wrong resolution. For example, my Samsung SyncMaster 971P monitor has a maximum resolution of 1280x1024. When using a TV and a computer monitor at the same time, the main thing for me is to correctly set the resolution on the TV, otherwise why did I connect it then. I set the resolution to 1366 x 768 on the Samsung TV, the picture is perfect.

And on a computer monitor, this resolution of 1366 x 768 looks like this.

And nothing can be done here. If you want a perfect picture on a TV and a computer monitor, then they must support the same screen resolution, that is, they must have the same characteristics. No sound on TV after connecting TV to computer via HDMI Friends! Do not forget that the HDMI interface transmits video and sound over a single cable, and we can specify in the operating system settings to use the TV's built-in speakers for sound output.
Let's fix the problem by using a TV instead of a monitor. Go Start->Control Panel->

Hardware and Sound->Sound

If you don’t have anything in this field, right-click on an empty spot and in the menu that appears, check the items “Show disabled devices”. "Show connected devices"
Now we look at the name of our TV, in my case it is Samsung, you need to turn it on, and turn off the rest. Right click on Realtek and select Disable.

Turn off the speakers too.

Samsung - Enable, Apply and OK.

Each of us at least once thought about connecting a computer and a TV to each other, displaying an image from a monitor on a large screen using HDMI technology or a router. This is not so difficult to do, there are quite a few ways to connect: using cables of several formats - HDMI, DVI or VGA, via an Internet connection using a network connection.

Wired connection provides the best signal transfer between devices

We will focus on each of them and learn how to adjust the picture when displaying it on a TV.

There are several connectors through which the PC and TV are connected. DVI and HDMI cables provide a high quality signal, while using the VGA format will only allow you to get an analog image.

The subsequent choice of cable depends on what sockets are on the equipment - it is important that they match or that an adapter can be placed on one of its ends.

If your computer does not have a built-in HDMI card, or if you are going to connect it to a TV using a different cable format, you need to purchase an audio wire, otherwise you will only get an image. It connects through the audio jack - a round hole with a diameter of 3.5 mm and connects the input on the PC soundbar and the connector on the TV or external speakers.

Connecting via VGA

This connection format will allow you to see an analog image without sound, which will not be of too high resolution, respectively, of imperfect quality. However, if there are no other types of connectors, use this particular method to connect equipment.

To do this, follow these steps:

• Turn off the computer, connect the equipment to each other using cables for audio and image;
• Turn on the TV and select the connection item in the settings (the section may be called Source or Input), stop at the VGA item;

Go to the audio menu and make sure the settings are set to output sound through the cable you connected, and not another interface (for example, HDMI).

• Turn on the computer - the desktop image should appear instead of the TV.

Video signal input via DVI cable

This connection method will allow you to enjoy a digital rather than analog picture, but still without sound.

Please note that there are various types of cables in this format, make no mistake when choosing and purchasing. In general, the connection between the PC and the TV is established in the same way as in the previous method, only select the DVI format in the video signal reception settings.

HDMI connection

This method of supplying video and audio signals to TV is the most relevant and profitable today, because you will receive a high-quality digital signal with sound - provided that the computer has a built-in HDMI card.

Using this connection, you can display a picture on a screen with a large diagonal without loss of quality, which will especially appeal to fans of movies and various games.

When buying an HDMI cable, consider the location of the equipment in the room - if the screen is located on the wall, it will not be possible to simply insert a straight plug. There are various types of cables where the plug is turned 90 degrees or made in the form of a corner - it fits well between the back of the TV and the wall.

The connection is done like this:

• Turn off the equipment from the network, connect it with a cable through the HDMI connectors;
• Turn on the TV, in the connection parameters (Source or Input), select the required type of connection.

It happens that one HDMI port on a TV is not enough, and to solve the problem, there are switches - “hubs” that allow you to connect several devices to it at the same time.

Image Adjustment

After connecting the equipment using one of the above methods, you need to adjust the image. Do the following:

• In the context menu of the desktop (it is turned on with the right mouse button), open the "Screen Resolution" item;
• In the Screen section, the line "Multiple monitors" is selected if you connected a TV and did not disconnect the computer screen.

When setting the resolution, stop at the highest setting for the sharpest picture, but keep in mind that the higher the value, the smaller the icons will be.

Working with multiple displays

You can use multiple monitors at the same time like this:

• The duplication mode is a complete match of the image on both the PC and the TV - your actions are visible on all monitors connected to the system unit;
• "Expansion" - a mode for combining two screens so that each of them is independent.

To change the resolution on a separate device, select it through the "Screen" item and make the necessary settings.

Using a network cable

In addition to the above methods, a computer and a TV can be connected to view videos or photos on a large screen using a Wi-Fi router. This requires a LAN port on the equipment and a network cable, after which a special media server is installed.

It all happens like this:

• Connect the TV to the router with a network cable to the LAN socket and install a media server on it using the following steps;
• Download a program to broadcast data from a computer - most users choose the Home Media Server utility;
• After installing the program, select your TV in its settings menu, then mark the sections on the PC that you would like to view on it;
• Run the program;
• Turn on the TV, select the Source section in the parameters, after which a program will appear in the list through which you can view files from your computer.

In a similar way, two devices are connected directly through the LAN ports - on the one hand, the cable is inserted into the TV socket, the other end is connected to the same port on the back of the system unit, creating a network connection.

Important! To combine technology using the above two methods, you need to set the DHCP network settings on the TV. If they are not enabled automatically, you must manually enter the following data:

• In the operating system: go to the Control Panel, open your network and view its properties - select Internet Protocol 4 and enter the IP address 192.168.0.1, the subnet mask - 255.255.255.0. The DNS server combination is the same as the IP value;
• We enter this data in the network settings of the TV.

Connection via Wi-Fi

Modern TV models have a built-in Wi-Fi module, which is useful to you in order to connect the device to your PC and display the image on the screen.

To do this, connect to a wireless network through the hardware settings, connect to this network on a personal computer. Now, through the Control Panel, go to the screen menu, turn on the search for monitors in the resolution settings window. When the computer detects all monitors, you can cast your desktop to the big screen.

All the described connection methods will allow you to transfer the image from the computer screen to the TV. In principle, combining equipment with an HDMI cable is one of the most attractive and logical options, since this signal transmission format will allow you to get a high quality picture with clear sound. But the choice of the optimal method depends on the parameters of the technique and which of the listed options will be most convenient for you.
