How To Stream Video From Computer To TV

Output and broadcast of images from a computer to a TV via Wi-Fi

Sometimes it is convenient to view both on the computer and on the TV. Modern wireless technologies provide this opportunity. To do everything right, you need to figure out how to transfer an image from a computer to a TV via Wi-Fi. This article will detail how to do it.

How to Cast from Computer to TV with Google Chromecast

This device is a minicomputer running on the Android operating system. It is connected to the HDMI input of the TV. It can receive from a laptop and duplicate one of the tabs of the Chrome browser on the screen. In addition, it can work directly with the service. In this case, the laptop can be turned off, and the device will broadcast directly from this site or broadcast TV programs.

Miracast technology

Previously, there was a need to separately purchase a Miracast wireless adapter. Now, most TVs are equipped with this communication protocol out of the box or receive it with a firmware update. This solves the problem of how to output the image from the computer to the TV via Wi-Fi.

The computer must be equipped with a wireless adapter that supports Miracast.

The connection procedure is as follows:

  • Miracast support is required in the TV settings. Samsung TVs call this feature Screen Mirroring. If it is not possible to set the desired settings, then in this case you need to make sure that Wi-Fi is turned on.
  • On a laptop, open the Charms bar. In Windows 8.1, it is located on the right side of the screen. Then go to “Devices”, then. to “Projector (Transfer to Screen)”. After that, you need to click the mouse on the item “Transfer to wireless display”.

Note! If it is not possible to find the last item, it means that the computer does not support this method of communication. In some cases, it will be able to, if you transfer the wireless adapter driver to a new version.

Miracast support in Windows 7 and above is built-in. For example, in this operating room, in order to use the TV as a monitor via Wi-Fi, you need to do the following:

  • Press the WinP key combination. It is not necessary to press it for too long, as in this case the screen may go out.
  • Then the screen will show the menu related to the design. In it you need to click on the line “Connection”.
  • The operating system will provide a list of devices connected to the wireless network.

After that, the broadcasting process will begin.

Transfer media from laptop to TV via Wi-Fi (DLNA)

In this case, the movie, which is being watched on a laptop, will SIMultaneously be shown on TV. A wireless network is required to display images. To display, you need a wireless adapter. In this case, the laptop must be connected to Wi-Fi. When these two devices are connected at the same time, the image will be transmitted.

Some devices use Wi-Fi Direct technology. In such a situation, it will be possible to do without a router. The wireless network will be provided by the TV.

Connection to Wi-Fi is made from the corresponding menu during setup.

The first step is to set the desired parameters on the TV.

If you have a router to which the devices are connected, then you need to do the following:

  • On the remote control, select the entrance to the settings.
  • In the menu you need to go to the item related to network connections.
  • Next, you need to select the section on wireless connection.
  • Select the required network from the list of available networks and enter the security key.

If you have the Wi-Fi Direct function, you need to do the following:

  • Enter settings.
  • Go to the Wi-Fi Direct section in the menu.
  • Enable this mode. The screen will display the name of the wireless network and the security key.

Having received the necessary data, you can connect to this network.

The next step is to configure the DLNA server.

As an example, we will consider how this can be done on Windows 7:

  • If using Wi-Fi Direct, then you need to connect to a wireless network. In this case, you must select a home network.
  • If you have a home router, there should already be a connection to it.
  • Further, the procedure boils down to organizing shared folders on the computer, where it will be located for viewing.

This is done like this:

  • Right-click on the folder name and go to its properties.
  • Go to the “Access” tab and select advanced settings.
  • Check the corresponding box to enable sharing of the folder.

To configure, it is enough to indicate that the wireless network is private. In this case, the “Documents”, “”, “Music” and “Pictures” folders are shared by default. You can add arbitrary folders to them, go to their properties, go to the “Access” tab and set general access in it to be able to send files.

Now in the control panel you need to go to the network section and go to the home network settings. You need to create a home group and open access to the necessary folders.

After DLNA has been turned on, you need to go to the Home button on the TV and go to the section for viewing available files on the screen.

File c must be in the shared folder. They go into it on a PC, right-click and select the “Play on TV” item. Here, instead of the last layer, the name of the TV is indicated. After starting, the stream will be transferred to the screen.

With this connection method, you can use the Media Player software to dub view files. To configure it, you need to do the following:

  • After starting the program on a laptop, click the “Stream” line in the upper horizontal menu.
  • In the menu that appears, click the line “Allow access via the Internet”.
  • While the broadcast is in progress, the program should work. It is possible to turn it off after the end of the stream.

During the entire time of connection, the player will broadcast the file being played to the TV screen of Sony, LG or Samsung.

Important! For such broadcasting, programs that have a DLNA server function can be used. The most popular ones are: Kodi, TVersity, Plex, HMS (Home Media Center), Samsung Allshare, Mezzmo, Serviio.

In the VLC player, you can broadcast by selecting the “Broadcast” item in the “Media” menu. Then you need to go to the “File” tab and specify the file you want to broadcast. However, to view it on TV, you need to launch a browser on it and specify the IP address of the computer on the home network. It is possible to do this using Chrome cast.

How to connect a regular TV to a laptop via Wi-Fi

To do this, the TV must have a built-in wireless adapter. To watch TV this way, you first need to set it up correctly. In this case, proceed as follows:

  • Open settings.
  • Go to the section related to network connections.
  • Select a wireless network connection.
  • Open settings options. A list of available connections will be shown. You need to choose the one you want and connect.

To configure, you can use the free program “Home Media Server” (you can download it from the link. When you start, you will be prompted to add it.

How to transfer the image to the TV via Wi-Fi depends on the brand. Usually you need to go to the settings and select the DLNA server among the available connections.

After that, you can play the files on the screen on the laptop.

Displaying images using Wi-Fi (mirroring the laptop screen on a TV)

To use the TV screen to mirror the image on the display, you need to use Miralinks technology or Intel WD.

TV requirements

In order for the laptop to be able to transmit images wirelessly, the TV must have a wireless adapter. In the process of work, it will be connected to the home router and will receive from it.

Modern models of Sony Bravia, Samsung and others may adopt Wi-Fi Direct technology. In this case, the TV itself creates a wireless network. In this case, a router is not required to organize communication between devices.

Important! You can even stream to a TV that doesn’t have a wireless adapter or Wi-Fi Direct. An HDMI input is sufficient for this. In this case, a mini PC the size of a USB flash drive can be connected to it.

WiDi technology

To transfer this way, you need a computer that uses an Intel processor. It must be 3rd generation or older. A built-in wireless adapter from this company is required. You will need to install the Intel Wireless Display program from the Intel official website.

How To Stream From Computer To TV

To connect, you need to do the following:

  • Enable WiDi support.
  • The laptop requires Intel Wireless Display to be running. All devices that were online will be displayed. We need to find a wireless monitor. Security key may be required during connection.

After completing these steps, the image from the computer display can be duplicated on the screen.

Transferring images from laptop to TV via Wi-Fi

In this case, the live broadcast of the image from the laptop screen to the TV is considered. In practice, in this case, the computer receives another display.

Important! In this case, you do not need to use a router for wireless connection. In this case, you can send data between devices using Wi-Fi Direct.

Intel WiDi and Miracast on TVs

We figured out the devices that will transmit the image over the air, now with regard to the TVs that will display this very image. On a TV set, either integrated support for Intel WiDi / Miracast is suitable, or you will need to take a special receiver that connects to the HDMI connector of your TV set.

As I figured out, all TV sets from the favorite manufacturers: LG, Samsung, Toshiba. since the development of the 2013 line, and which have support for Smart TV, have integrated receivers and can work with the Intel WiDi / Miracast standard.

If the TV does not have integrated support, then, as I already wrote, an external HDMI adapter will help. When, through it, the image goes even better than through the integrated.

For example, the LG 32LN575U TV is a cheap model with Smart TV function, there is support for Intel WiDi / Miracast. It looks like this:

Maybe I will somehow demonstrate the work of this technology, but this will already be in another article.

How to watch through a cable?

To watch movies from a computer via a cable, first of all do the following:

  • Disconnect laptop / computer and smart TV.
  • Disconnect antenna and other equipment from the TV.
  • Connect cables and switches.
  • Turn on your PC / laptop and TV.

With the correct connection, select the appropriate channel in the TV, which can be tuned through the laptop. It remains to configure the transmission.

Image on a TV set from a laptop or phone via Wi-Fi

I saw that some people want, for example, to launch an online movie on a tablet, in a browser and display it on a TV set. Let’s not forget, if you want to be, in order to transfer a movie via DLNA, you must first download it. Not everyone likes this, in addition, not everyone knows how to download films on a tablet or phone. If you have Smart TV, then you can easily watch online movies directly from the TV, and you don’t need any additional devices for this purpose. How to make this common rumor, read here.

There are two main technologies that allow one hundred percent duplication on a TV set over a wireless network, what remains to be done for our client, what you see in the cinema of your own laptop or mobile device. These are Intel Wireless Display Technology (Intel WiDi). and Miracast. Most likely, you have already heard about these developments, or have seen them in the settings of your own devices.

Configuring Network Access to Computer Files in Windows Media Player

The way to configure access to computer files in Windows without the need to install third-party software is to use the standard Windows Media Player.

On the Windows Media Player toolbar, click the Stream option and check the box next to:

  • Enable streaming media.

After enabling this parameter, a system window with streaming parameters will open, where you can specify the name of the media library and flexibly configure the availability of media content for specific network devices: for some, leave the preset resolution, and for others, remove.

Configured permissions will allow other devices to access files only in the user profile folders over the network. These are folders “”, “Music”, “Pictures” that are displayed in Windows Explorer along with the disk partitions, drives and removable devices of the computer. If this is more than enough, you can already start testing the playback of files on the TV using local applications that work with DLNA technology.

But storing files in user profile folders on the system drive is not a good idea both from the point of view of the availability of free space on the C drive, and from the point of view of the safety of these files in case of a critical failure of Windows. As a rule, large media libraries are stored on non-system partitions of the computer disk. The folders of such libraries must be added to the Windows Media Player library in a separate step.,

To make the contents of other computer folders available for streaming to the TV, in the Windows Media Player window, click the “Organize” option, select the “Manage Libraries” item, and in it. one of the content types: “Music Library” for audio files, “” for files, “Gallery” for photos and pictures.

A window will open with a list of existing libraries, and to add the desired folder to this list, press the “Add” button on the side. Add this folder in the window of the explorer that opens, then click “OK” in the window with the list.

An alternative way to add folders with media content to the system list of folders with open access for home network devices is to add them to the library using the context menu command in Windows Explorer. At any time to any folder on your computer where it is stored. music or photos, you can open access for playback from network devices. To do this, open this folder in Explorer, call the context menu and select the “Add to Library” command. The folder will be added to the corresponding library and its contents will be available for streaming.

The list of folders with open for streaming. and audio files will also change when you make changes to it using the standard Windows 10 applications “Movies and TV” and “Groove Music”. In the settings section of both applications, you can add and remove folders to local collections. and audio files. Local application collections work in conjunction with system libraries.

How to use DLNA Server on Windows? Stream media from PC to TV

One of the characteristics that distinguishes some modern TVs from others is the degree of their intelligence. In a figurative sense, of course. We are talking about the technological advantages of the so-called Smart TV. Conventional digital TVs, as a rule, can play the role of the TV itself, working in tandem with the receiver, play media content using the built-in player (alas, often with a limited list of readable formats), and also serve as a monitor for a computer, game or TV set-top box. Whereas Smart TV, they are also smart TVs, are able to participate more in the content playback chain as independent participants.

Which devices support Intel WiDi and Miracast?

As for computers (laptops). then Intel WiDi technology requires a 4th generation Intel microprocessor, Intel graphics, and Intel wireless Wi-Fi adapter. Now you understand, a rare laptop can boast of such a configuration. Or, a special prefix will come in handy.

If we talk about mobile devices, then there is also desirable support for Intel WiDi, or Miracast. If you intend to use these technologies, then look at the properties of the devices and check the availability of these technologies before making a purchase.

Detailed information on devices that support this technology can be viewed on your own website

Cable connection

How to quickly play a movie? Connecting via cable is considered the easiest and takes less time.

Before buying, see what ports are present in PC and Smart TV. Also measure the distance from the system unit to the second monitor so as not to change the cable several times.

  • USB connectors are built into every laptop or computer, they are also used to create a connection with a TV. This can be done with a USB to HDMI or VGA converter. One of these ports must be present to connect a TV.
  • S-present in all new computers, Smart TV. It is used only for transferring tracks with a quality not exceeding HD. The audio track is not transmitted by such a cable.
  • SCART is a popular port in televisions for transmitting and audio signals. In a laptop and a computer, this port is absent, therefore they use the S-Video-SCART, VGA-SCART connection.
  • RCA is an interface with three connectors, equipped in all modern TVs and cards. Signal transmission quality is worse than in previous versions, especially with regard to color rendition.

How to Stream Media from Computer to TV over Wi-Fii

Let’s say you have a good collection of media on your PC in one room, but you want to be able to watch it on a nice big TV in another room. Windows offers an easy way to do this over Wi-Fi.

There is an open standard for sharing media files over a home network. It’s called the Digital Living Network Alliance, and you probably already have what it takes to use it. There is a second and newer miracast standard and will have a special note for Windows 10 users. First, some definitions for the tag: the device that sends the stream — for example, the computer is a DLNA server. A device that accepts a stream. such as an HDTV or anything related to television. is a DLNA renderer (I hate that term; a player or receiver would be much nicer). Both devices must be on the same network.

Configuring network access to computer files using the Home Media Server program

Another way to provide access to TVs, set-top boxes, mobile and other devices that support network and DLNA technology to the media content of a computer is the Windows program “Home Media Server (UPnP, DLNA, HTTP)”. The program works with many popular TVs: LG, Samsung, Toshiba, Sony, Philips. With this program, a DLNA server is launched on the computer, to which all devices on the network can connect. By default, the program allows you to control server files from the TV. in fact, computer files.

The advantage of using Home Media Server over all of the above methods of providing access for streaming is more features and more customization. The program provides for the presence of various transcoders. and audio files, which allows you to convert media content, if it originally exists on the computer in a format unsupported by the TV, into the format that it supports. You can additionally set up the broadcast on the TV of individual Internet channels (radio and digital television).

“Home Media Server” can be downloaded absolutely free on the website of the creators.

Download the program, install it and run it. At startup, the initial settings window will appear immediately. In it, you can leave everything by default and refuse to scan media files. Let’s go to the program settings in a separate order.

In the program window, click the “Settings” button on the toolbar at the top of the window.

In the settings window that opens, we will see tab categories on the right. In the first tab “Media resources”, we can use the “Add” button, respectively, to add any folders with media content to the program list in order to open them access for streaming. Sharing can be opened at once to all partitions of a computer disk (C, D, E, etc.), to all network drives, to all connected removable media. To do this, check the boxes at the bottom of the window next to the necessary options. respectively, “Local drives”, “Network drives” and “Removable devices”.

The Media Resources settings tab provides many options for the added folders. For example, by clicking the “Change” button, we will be able to exclude hiding files and directories, remove certain file types, set a different folder name. and all this is within the DLNA server, without changes on the computer.

At the bottom of the “Media Resources” tab, there are separate sections with an abundance of different settings. In the “Scanning” section, you can pay attention to the option “Always use the file name as the name of the media resource”. Without checking this option, the names of media files in Russian will be converted to transliteration in Latin or into unreadable crocozyabra.

In the “Devices” settings tab, we will see a list of all detected network devices that will have access to the DLNA server files. Any of the devices on the list can be disabled by removing the green activity button.

In the “Server” settings tab, instead of the default DLNA server name, we can set our own name, for example, more user-friendly. Next to the server name field we will see its port. 45397. It may happen that the antivirus or firewall running on the computer will block the DLNA server. In case of such blocking for the DLNA server port, you must provide permission to work in the antivirus or firewall settings.

Also, in the “Server” tab, you should pay attention to the default option that prevents the computer from going into sleep mode while the DLNA server is running. If it becomes necessary to put a PC or laptop into sleep mode, the DLNA server will need to be stopped in the future. If, on the contrary, the checkbox on the option “Prevent the computer from entering sleep mode while the server is running” is not checked for some reason, it is better to set it. Otherwise, watching a movie on TV will be unceremoniously interrupted as soon as the laptop falls asleep to conserve battery power.

The Home Media Server program has a very rich choice of settings, and its potential can be unlocked gradually, testing certain features as you become familiar with them. In the meantime, we will restrict ourselves to the already done settings and save them. Click “Ok” below and agree to scan media files in the configured folders.

After the program completes the scanning process, we can start the DLNA server. To do this, press the “Run” button on the toolbar at the top of the main program window.

Home Media Server runs in the background and the program can be controlled from the system tray. By calling the context menu on the program button in the system tray, the DLNA server can be stopped, started, restarted.

You can automate this process so that the DLNA server starts automatically when Windows starts up in the program settings. The last tab of the “Advanced” settings provides in the “Startup” column the options for autoloading the program itself at Windows startup, autorun the DLNA server along with the launch of the program, as well as installing its background service in Windows.

Once the DLNA server is up and running, all of the available media content on the computer can be played on the TV through the local DLNA technology interface application. The DLNA server will appear as the connected playback device in the TV app. Inside it will be available folders with the media content of the computer, configured in the program “Home Media Server”.

You can launch available media content for playback not only in the TV application. You can also instruct the Home Media Server program to start playing media files on your TV. To do this, in the main window of the program, select the appropriate content. click on the toolbar at the top of the button “Movies”, “Music” or “Photos”. On the right side of the program window, the files of the folders will be displayed, which were previously opened for broadcasting to the TV. Select the desired., audio file or picture in the list, call the context menu on this file and select “Play to” among the commands. In the list of devices that appears, select the TV. The selected movie, track or photo will unfold on the TV screen.

Instructions for Windows 7

Right click on the file and select “Play To”. Click on the TV. After that, a player will appear, where you can manage the selected files, change the order of their display. To replenish the list, transfer files through the player. This way you can control the display remotely by adding new files to it. You can also combine photos, music and other films with each other.

It happens that before transferring the image, the Media Streaming Options window appears. Click “Enable Media Streaming”.

In the next window, check for a permitting checkmark next to your TV model.

Repeat the file transfer procedure.

When using Movies TV on Windows 10, the method is slightly different. Open the menu and click “Transfer to device”, click on your TV. All files will be broadcast on the second monitor. Optionally, you can set what will be played.

If the PC does not see the TV

Outputting to a TV is SIMple, but causes complications or problems. Everyone has different devices and techniques may differ. First, check if everything is connected correctly and which devices are participating in the broadcast.

What should I do if the TV does not appear in the list of new devices on my computer? It is enough to wait a little without closing the list, and the TV will appear. First of all, make sure that the output device has Smart TV function and is connected to the same router as your computer. Check the connection and functionality of the output device.

Other possible problems:

  • The file does not play, the message “Format not supported” appears on the screen. A common occurrence, the reason is the lack of file format support. Either the case is related to the computer: on the Windows 10 operating system, the file starts without problems, but with Windows 7, an error is issued.
  • Slows down music / movie playback. If the file is of high quality or weighs a lot, it slows down during playback. If the internet speed drops, the picture will start to slow down. For example, Full HD format is played without delays. If it’s 4K, then it’s better to get a router with a 5 GHz range.
  • There is no sound. Go to sound settings. It is located next to the clock, then in “Playback devices”, “Using the default speakers”.

Create a media server for better performance. Use one of the following applications:

  • Home Media Server. many features and customization of the program for yourself.

Instructions for Windows 10

Select the desired file, right-click. In the window that appears, select “Transfer to device”. Then select the name of the TV.

Wi-Fi connection

Broadcasting wirelessly is a complex technique that deserves special attention. But it remains the most popular because every home has a router. Before connecting, you need to prepare several devices, which you cannot do without:

  • A computer, laptop, or other device that plays. Through it you start the server.
  • DLNA TV. It will port everything contained on the PC. If there is a built-in Smart TV function, then the connection will be easier.
  • Internal network connecting laptop, TV. 2 gadgets need to connect to one router.

Developers release Smart TV and computers with DLNA technology support. If this function is built in, it will be enough for playing music. films. DLNA instructions will be below.

TV box

Such a set-top box almost completely copies the functionality of the new Smart TV, but the list of features is larger and easier to manage. For example, consider Apple TV:

  • Connect it to your TV.
  • Start browsing. audio, photos and other content.

Once connected, you will have access to movies and photos that are stored on your iCloud and iTunes account. You can also play small toys by connecting multiple gamepads to the console.

Of course, Apple TV is tailored for users of Apple products only with licensed files. Therefore, many people choose consoles with the Android system, where there are more options and freedom of action. You can watch movies, others through the browser, download the application through the Play Market. In fact, these are the same smartphones on the Android platform. In addition, you can connect a keyboard, mouse for quick text input.

Cable connection

How to quickly play a movie? Connecting via cable is considered the easiest and takes less time.

  • DVI is a popular interface and has the same signal quality as HDMI. But before buying, keep in mind that the audio track does not go through the cable if the specified function is missing on the ATI card. Using this connection, connect additional cables with audio transmission function.
  • The VGA cable will be older than the previous one, but it remains relevant to this day. The connector is present on almost all modern devices, but some TV manufacturers are gradually getting rid of the VGA port.
  • USB connectors are built into every laptop or computer, they are also used to create a connection with a TV. This can be done with a USB to HDMI or VGA converter. One of these ports must be present to connect a TV.
  • S-present in all new computers, Smart TV. It is used only for transferring tracks with a quality not exceeding HD. The audio track is not transmitted by such a cable.
  • SCART is a popular port in televisions for transmitting and audio signals. In a laptop and a computer, this port is absent, therefore they use the S-Video-SCART, VGA-SCART connection.
  • RCA is an interface with three connectors, equipped in all modern TVs and cards. Signal transmission quality is worse than in previous versions, especially with regard to color rendition.

How to watch through a cable?

To watch movies from a computer via a cable, first of all do the following:

  • Disconnect laptop / computer and smart TV.
  • Disconnect antenna and other equipment from the TV.
  • Connect cables and switches.
  • Turn on your PC / laptop and TV.

With the correct connection, select the appropriate channel in the TV, which can be tuned through the laptop. It remains to configure the transmission.

How to stream from PC to TV

It would seem that such a SIMple procedure for modern computers and TVs as output to a TV should not cause any special problems when using an HDMI cable, network cable or Wi-Fi, but as always there are nuances. And the average man in the street, at times, has to spend a lot of time to figure it out and bring it to the TV the way he wants. In this article, we’ll take a look at how to set up software and TV output options.

If the monitor size and TV size are different in resolution, HDMI cable output

Recently, manufacturers of modern TVs have been releasing TVs exclusively with Full HD resolution (1920 × 1080 pixels). We will not consider 4K TVs due to their high cost, and at the time of this writing, they are clearly not affordable, both for me and for you. over, the purchase of this TV in the absence of it in 4K format makes the purchase of such a TV, at the moment, clearly redundant.

So, if the resolution of the computer and TV screens is different, then when outputting to a TV via an HDMI cable, when setting up the TV, show in the original resolution (the best choice, so that there is no distortion of the original vertically and horizontally), on the TV we will see black bars at the edges not occupied by the material. This is due to the fact that when you connect a TV to a PC via HDMI, you get an extension of the computer desktop to a second monitor. a TV. In this case, the extension of the desktop to the TV takes place with the dimensions in the horizontal and vertical points of the computer monitor. But since the resolution of the computer screen is different from the resolution of the TV, then we see black bars. For example, the resolution of the PC monitor is 1680×1050 pixels, and the resolution of the TV is 1920 × 1080. In this case, there will be black bars on the left and right of the TV that are not occupied by the image.

To solve this issue, let’s turn to the driver of the computer card (in the example, the driver of the card produced by AMD will be considered, for NVIDIA we do it in the same way). We go to the driver settings in the lower right corner of the PC monitor. At the same time, the TV must be turned on in any mode, at least for watching terrestrial TV broadcasts, so that the PC determines that there is another monitor connected via an HDMI cable.

Or via the path Start, All Programs, AMD Catalist Control Center

In the window that appears, select the second monitor. your TV

Now you need to select the required HDMI input on your TV to output images from your PC. In fact, this is the input where you connected the HDMI cable to the TV. When the picture of the PC desktop appears on the TV, we return to setting the card driver.

We start the movie, after checking in the file property that it is in Full HD format (1920 × 1080 pixels).

Note. I recommend viewing files exclusively in the Media Player Classic, which is included in the package of free K-Lite_Codec_Pack codecs, and it doesn’t matter if you have a full or mega pack codec installed. the player is always included in the package. This player is one of the few that plays all files with any extension. over, when viewing, you will have the opportunity to customize that sound, which is for your needs. this player allows you to change any settings when viewing on the go.

With the movie running, drag the player window to the second monitor. the TV, and expand the view to full screen. Now, using the “Scaling Setting” slider in the map driver, you need to adjust the size horizontally to fit the entire screen. over, if you do not adjust horizontally, then when viewing 3D you will definitely have a double image, for obvious reasons, even if you are wearing the appropriate glasses. Usually you need to move the slider slightly to the right, and sometimes even to the very end.

So, we have established a connection via HDMI cable with different resolutions of the monitor and TV. It’s time to consider connecting via an Ethernet network cable or Wi-Fi network.

If. e.g. 3D, not pinched correctly, or resized to save space

Sometimes when watching 3D. output through a PC, you can observe the following picture. the image on the TV is flattened on the sides. As a result of this distortion, there can be no question of any 3D image on the TV. For clarity, I will give an example of how it looks on a computer and, for obvious reasons, something SIMilar can be seen on a TV without turning it into 3D.

There are black bars on either side of the image. We will try to get rid of them.
And this is solved quite SIMply. Let’s use the same Media Player Classic.

Let’s start a SIMilar movie in the player and on the image by pressing the right mouse button, we will call the menu.

Select the frame, Stretch to fit the screen.

As you can see, the image is stretched, and this is what we wanted.

Now all that remains is to drag the Media Player Classic window to the second screen. to the TV and switch the latter to 3D mode.

After these player settings, you can view both 3D and normal material with incorrect compression on the entire TV screen without additional manipulation of the TV settings.

Connecting a TV via an Ethernet or Wi-Fi network cable

This method of connecting a TV to a PC has a number of additional possibilities compared to dragging the window with the player to the second window. to the TV.

You can control the viewing from the TV remote control. Switch files for viewing, rewind content, control sound volume. And to implement all this, you need to install on your computer just the free Home Media Server (UPnP, DLNA, HTTP).

I will not talk in detail about setting up this home server, so that there is plenty of information on the global Internet. And I’ll tell you in more detail about how to set up your TV and router.

Let’s start with the installation of the Home Media Server itself (UPnP, DLNA, HTTP). Download the installation package of the program from the link and install the media server on your PC.

After installing and launching the program, go to the settings and specify the folders with the material that we want to view. Press the “Settings” button.

In the window that appears, click the add button

The program will offer to scan the added folder. we agree

After scanning, start the server and minimize the program window

Let’s move on to setting up the TV, in an example we will consider connecting to an LG TV. And in order not to pull the wires, we organize the connection using a wireless Wi-Fi network.

We go to the TV settings. Choose Network, Connect to Wi-Fi

From the drop-down list, look for our router and click on it

A field for entering the wireless password appears.

Enter the required password using the keyboard on the TV screen and press Enter

If you did everything correctly, then in the line next to your router there will be a checkmark indicating that the connection is established

We exit the TV settings and go to the connection manager

In the connection manager, select Personal computer (PC)

Next, we choose to share the TV screen

Select our media server and click on it

After connecting to our server, select Films

Next, media resource directories

And finally, our added folder

In the opened folder, we are looking for the necessary material and click on it to view

That, perhaps, is all with the settings for output to the TV using a wireless Wi-Fi network. As you can see for yourself, there are options for rewinding, selecting the desired movie, adjusting the volume from the TV remote, etc.

In conclusion, we can add that after connecting the TV via Wi-Fi, it is not at all necessary to go to the TV connection manager. It is enough to select the desired movie in the media server, right-click on it and select Play on TV in the drop-down menu. After that, the TV will automatically switch to the media server itself and start showing.

The function allows you to pair devices on a Wi-Fi (home network) network and view files in a slideshow. It is advisable to use this type of communication if your TV does not have the SmartTV function, but is connected to the AppleTV, DuneHD, etc.

We draw your attention to the fact that in the method of communication between a smartphone and a TV via DLNA, it is impossible to broadcast an image online to TVs that do not have the SmartTV function. For everyone else, real-time image transmission is feasible.


One of the easiest ways to connect your smartphone to your TV is a USB to HDMI cable. In this case, the smartphone must have a micro-HDMI connector, and a free HDMI input on the TV. If, according to the technical characteristics, your smartphone does not have a micro-HDMI port, then we recommend that you use a micro-USB-HDMI adapter (converter).
