How to display your computer screen on TV

How to connect your TV to your computer as a second monitor?

If you want to use your TV as a main display you can use this connector. To connect you will need a standard VGA cable. Connect one end of the cable to the VGA OUTPUT connector on the graphics card of the computer, and the other end to the VGA INPUT connector on the TV.

If the TV does not see the laptop, but the connection is made, then the reasons may be the following: Incorrectly connected cable or it is faulty. Monitor settings error. Laptop or PC video card does not work properly.

How to connect the laptop to the TV via Wi-Fi

Synchronization of laptop and TV with the wireless network only seems to be a complicated process at first sight. If the user gets into the details, he will quickly understand how to connect the laptop to the TV via Wi-Fi.

Why should you waste your time with wireless sync if you can connect your laptop to TV using DVI and HDMI interfaces?? Firstly, it is not always possible to have the necessary cable at hand. Secondly, not all laptops have these interfaces. Third, a TV connection over a wireless internet channel looks like a more practical solution.

This type of synchronization is especially useful if you want to watch a movie or a new episode of a TV show online. Still, watching video content on a screen with a small diagonal is not very enjoyable. Therefore, you can connect your laptop to the TV wirelessly to enjoy a high-quality and voluminous image.

If the laptop has a Windows operating system, then you can use one of the following ways to connect:

How to transmit a movie, TV series or any other content from your laptop computer to the big screen TV? Let’s consider each of the above options, as well as highlight the most optimal way.

DLNA connection

To connect a laptop to TV via Wi-Fi, you must first connect both devices to the same network. Modern models of TV-equipment support Wi-Fi Direct technology. in this case it is not necessary to connect to the same router, the TV automatically creates its own network. The user only needs to connect to it from the laptop.

How to output an image from your laptop to your TV? First set up the DLNA server. The essence is that the user opens the network access to the folders, within which the content is located. Connect to your home network. The music, video, pictures directories will immediately become available for viewing on TV.

To access other folders, switch to the “Access” tab found in the properties of each directory. Select the “Advanced Setup” item. Check the box next to “Open sharing”. Press “OK” for the changes to take effect.

It’s much quicker to sync your PC and TV using File Explorer. Select “Network”. An alert with the following text “Network Discovery” opens, click on it. Follow the on-screen instructions to set up a wireless connection between your computer and TV.

After setting up DLNA, take your TV remote control to check the available external connections. You will see a list of connected sources.

If you are using LG products, then go to “Smart Share” section, where you need to select “Connect to PC” command. On other modern TVs the synchronization algorithm is also as simple as possible. The main difference is the names of sections.

Once DLNA is activated, select the content you would like to play. Press PKM on the file. From the context menu, select “Play on” and click on the TV name.

Now every user knows how to connect a laptop to the TV via Wi-Fi by setting up a DLNA connection. Remember that even modern TVs rarely support MKV format. So you can not play files with this extension. The problem is solved by converting the file to another format.

“Sharing” folders and setting up sharing are key elements of laptop-TV synchronization via DLNA. WiDi is significantly different. It allows you to duplicate the picture from the laptop display to the TV screen. It is realized by using a wireless channel. Users often refer to this option as Miracast.

Setting up a synchronization with this technology has some specific features. You will need a laptop with a CPU from Intel, a discrete graphics card and a Wi-Fi adapter. For example, almost all modern models of Samsung laptops are connected to TV exactly through WiDi.

Preload the drivers for the wireless display. You may have to download them from the official Intel portal. It is important for your TV to work with WiDi. Older models do not support this technology. That is why users buy additional equipment. adapters. You need to clarify this point beforehand.

  • Go to the main menu of your TV.
  • Go to the “Network” section.
  • Tap on “Miracast/Intel`s WiDi”.
  • Move the slider to activate the option.
  • On your laptop, go to the program for wireless synchronization with the TV equipment. Intel Wireless Display.
  • A list of available devices will appear on the screen.
  • Click on the “Connect” button, which is next to the name of the TV.

Sometimes you have to enter an extra PIN. These are mostly simple combinations of numbers. 1111 or 0000.

To finish the WiDi setup, go to “Charms” section. Select “Devices” and then “Projector”. Here you need to add the TV screen. If the name of your TV is not here, then update the drivers of the Wi-Fi module.

Wireless monitor

This method allows you to turn your TV into a PC monitor. The technology has certain similarities to WiDi. So there should be no problems with the synchronization of the laptop and the TV. The main condition is that the TV and Wi-Fi module of the laptop support Miracast.

Connect via Wi-Fi to wireless monitor. To activate Miracast function you need to open TV main menu beforehand. If this option is not available, then simply enable Wi-Fi on both devices.

On your laptop, press the WinP key combination, then select the wireless monitor connection. Wait a few seconds. When the connection is established, the image from the laptop screen will be projected onto the TV display. This is how to create a full-fledged external monitor.

How to Output an Image from Your PC to Your TV Via Wi-Fi?

Select “Playback Devices”. To open these settings in Windows 10, you must first go to the sound settings and there go to “Sound Control Panel”. From here on the parameters will not be different. In the new window, in the list of available devices, you will see your TV, or a device “Digital Audio (HDMI)”.

How streaming video works

Streaming. a way to stream video and audio files over a local network. Remote playback has become common for most modern users. On a particular port the server waits for connection, after pairing the devices through it transmits video.

It is possible to broadcast several videos, even entire playlists, from the host computer. All actions performed on the main PC are reflected on other devices.

Broadcasts are supported by most personal computers or laptops. If you want to play a movie or a video from your PC on a Samsung, LG or any other model of LED-TV set, you must find out the IP-address of your computer. In Linux you can get it from the terminal with the command “sudo ifconfig”. In Windows operating systems from Microsoft in the command line must be written “ipconfig”. Then you can move on to the VLC media player settings.

Playing movies from your computer on your TV via Wi-Fi (DLNA)

For this, the most common way to connect your TV wirelessly, in addition to having a Wi-Fi module, it also requires the TV itself to be connected to the same router (t.е. to the same network) as the computer or laptop with the video and other content (for TVs with Wi-Fi Direct support you can do without a router, just connect to the network created by the TV). Hopefully this is already the case, and no separate instructions are needed. the connection is made from the corresponding menu of your TV in the same way as the connection to the Wi-Fi of any other device. See. a separate manual: How to configure DLNA in Windows 10.

The next step is to set up a DLNA server on your computer, or, more accurately, to share folders on your computer. It’s usually enough to have “Home” (Private) set in the settings of the current network. By default, the public are folders “Video”, “Music”, “Pictures” and “Documents” (you can share a folder by right-clicking on it, selecting “Properties” and the tab “Access”).

One of the fastest ways to enable sharing is to open Windows Explorer, select “Network” and if you see the message “Network discovery and file sharing disabled”, click on it and follow the instructions.

If that message doesn’t follow, but instead displays computers on the network and media servers, you probably already have everything set up (it’s quite likely). If that doesn’t work, here are detailed instructions on how to set up a DLNA server in Windows 7 and 8.

Once DLNA is enabled, open your TV’s menu to view the contents of connected devices. On the Sony Bravia, you can go to the Home button and then select the section. Movies, Music or Pictures and watch the relevant content from your computer (Sony also has a program called Homestream, which simplifies everything I wrote). On LG televisions. SmartShare item, there you should also see the contents of shared folders, even if you don’t have SmartShare installed on your computer. For other brands of TV about the same actions are required (and there are also their own programs).

Additionally, when DLNA connection is active, by right-clicking on the video file in Explorer (we do it on the computer) you can select “Play to TV_name” in the menu. Selecting this item will start wireless video streaming from the computer to the TV.

Note: even if your TV supports MKV movies, these files do not work “Play to” in Windows 7 and 8, and they are not displayed in the TV menu. The solution, which works in most cases, is simply to rename these files to AVI on your computer.

How to connect laptop and computer to TV via WI-FI, transfer image, video to TV screen

The computer can be connected to the TV not only with HDMI. You can use your router and its “Wi-Fi” or Miracast technology, built-in TV and PC. How to set up the connection and transfer the picture from your PC to your TV using each method?

Why connect your computer to your TV?

TVs have a wider screen than computers (even stationary), plus the colors are richer and the picture quality is better. The pleasure of watching content is greater.

What features do users get if they connect their PC to their TV using Wi-Fi?

  • Play video games on the big screen;
  • Watch movies, shows, and videos that are saved on the PC;
  • Chat with friends and acquaintances over Skype from the big screen;
  • Do presentations.

Connecting your TV to your computer to play movies using DLNA technology

Before setting up, make sure your TV and PC are connected to the same Wi-Fi (the same router). This will mean that the devices are on the same local network.

Setting up your computer

The first thing you need to do is to configure the DLNA server itself on your PC. to share files and folders, which are on your PC, with everyone in your home group (the TV in our case). Let’s look at how to do this on Windows 7 and 8.1 without any third-party programs:

    Open the Control Panel. You can do this through “Start” (the item on the right). Click on “Homegroup”.

In the panel open the “Homegroup” section

Go to creation of a new homegroup

Share folders and files of different kinds

Allow all devices to play the shared files in the group

If necessary, change the name of the library with the files

Another way to share PC files is to enter the “Network” directory in Explorer on the left side. If the message “Network discovery and sharing are disabled” appears, click on it and activate the functions. Open the file on your TV or PC.

Click on the yellow notification and enable sharing

Do I need to configure DLNA on Windows 10

If you have a 10, this is easiest for you. You can use the DLNA feature (send videos from your PC to your TV display) without setting up the server. The only condition, we’ve mentioned above, is that TV and PC must be in the same local network of the router.

The picture will still be transmitted even if you use the public network (network discovery is turned off), and you have disabled File Access on your PC.

What you have to do? Just right click the video you want to play on TV, point the arrow to “Send to device” and select your TV-device (it has to be turned on and connected to “Wi-Fi” network).

After a while the file will run on the TV, and in “Windows” you will see the “Bring to device model name TV” window.

The TV will launch the video from your computer

Setup the TV

When DLNA is set up on your PC, you can access files on your TV from your PC. To see their list on a Sony Bravia TV, for example, click on Home on the remote control and select one of the sections with movies, music, or pictures. Select the desired file and open it. There’s also a Homestream app available for your Sony TV. just open it and go to your computer’s directory to see what’s on it.

Use a program to access files on your TV, such as Homestream

If you have LG, you need to find SmartShare section. TV will show folders from PC even if the latter doesn’t have SmartShare utility installed.

Open SmartShare and go to the section for your PC (computer)

Setting up DLNA on your router

If you have a router with a USB port, you can connect a USB flash drive with movies, videos, images and other files. And watch these files on your TV (it must be connected to this router via “Wi-Fi”). Before viewing on your router you will need to set up the same DLNA server after connecting a flash drive or removable drive.

The configuration will take place in the router’s web interface with the settings. The debugging process will depend on the router manufacturer. For example, the server configuration on Zyxel Keenetic is as follows:

  • Go to the router settings at in any PC browser.
  • Go to the “Applications” menu and open the DLNA tab. Check the “Enable” checkbox, and then click on the folder selection button.
display, your, computer, screen

Select the files and folders you need from the flash drive

In the shared folder appears the previously selected directories and files

Using your TV as a wireless monitor

Contrary to the previous method, here we will transfer not only separate files to the TV screen, but basically everything that happens on the computer display. So the TV becomes a second monitor for the PC.

The advantage of this method is that you do not need a mediator in the form of a router. The connection will be direct from the TV to the computer via Wi-Fi Direct technologies. Intel WiDi and Miracast. But there is also a disadvantage. both the computer and the TV must support the technology.

What devices support Intel WiDi and Miracast

As for laptops and desktop PCs. Miracast is a newer technology, so it is suitable for Windows systems from version 8 to 10. Previous versions do not support this standard. Minus to the technology.

Intel WiDi is no longer supported by systems. the developers (Intel) discontinued support for Intel Wireless Display back in 2016. In this regard, this method is considered irrelevant. we will consider only Miracast. To make this technology work, you used to need Windows 7 and a 3rd generation Intel processor or higher. Those users, who are currently running Windows 7, need to upgrade their OS to at least version 8.1 to upgrade to Miracast.

To set up Intel WiDi on your computer, you had to download the Intel Wireless Display software from the developer’s site

How to show the computer image to the TV set. the best ways

Experienced owners of equipment often use a TV as an external display on a laptop. This is convenient, because it is much more pleasant to watch your favorite movie on a big screen. You can also broadcast games and working presentations. To transfer an image from a laptop computer to a TV set is not as difficult as it seems. There are a few connection options. “by air”, using wireless technology or by cable.

What do you need to connect your laptop to the TV

You can transfer a picture from your laptop to your TV with a cable or via Wi-Fi. In the first case, look at the ports available on the equipment. Then they are connected by a cord and the picture is adjusted. The method is also relevant for transmitting images from a desktop PC. The main thing is that the equipment must be located close to each other, as cables are usually not long enough.

Another way is wireless transmission, which is very useful for the pairing of modern devices. This immediately eliminates the inconvenience of laying cables. Even if your TV is without a Smart TV, there is a way out. use an additional external device.

The image can be displayed using a wired or wireless connection.

Ways to display the image

When using a wired connection method, the ports on the devices may differ. special adapters are used for such situations. But if your data is digital and your TV input is analog, you will need to buy a converter or a set-top box.

The variant “by air” wins in that it does not require laying wires. But it has a disadvantage. bandwidth limitations and the probability of signal interruption. The cable connection has one disadvantage. the limit of the length of the cord. However, if you connect a laptop, but not a desktop computer. things are much easier, because it is easy to move.

Both devices are connected to a common network in order to display images from the computer to the TV. The new Samsung TVs support Wi-Fi Direct. which eliminates the need to connect to a router (the receiver creates its own network). All that remains for the user is to join it from his laptop.

To broadcast video from your laptop to your TV, you must set up a DLNA server. How it works: a user opens a network access to the folders where the media content is stored. Connected to your home network, you can play any content on your big screen.

Use Explorer to synchronize your laptop with your TV.

Setting up network discovery in Explorer.

  • Go to “Control Panel”. “Network” and click on “Network Discovery.
  • Just follow the tooltips, which will pop up on your screen, to configure the settings.

Having set up the DLNA-server, all that remains is to take the remote control and check whether new signal sources appear in the list of available connections. After activating DLNA, select the content that will be sent to the big screen.

Playing files through a DLNA server.

There is another technology which allows you to duplicate the screen. WiDi Miracast. It works wirelessly. But here there are some requirements to the laptop. chipset from Intel, discrete graphics card and Wi-Fi adapter.

To implement a wireless display, you will need to download drivers for it (it is better to look for them on the official Intel website). And the TV itself must support WiDi. If not, you buy an adapter.

  • Press “Menu” on the remote control.
  • Select the “Network” section.
  • Activate “Miracast/Intel’s WiDi.
  • The laptop download the program “Intel Wireless Display“, open it.
  • The screen will display the available devices.
  • Next to the name of the TV, click “Connect”.

Sometimes a pin code is requested. Usually this is a combination of numbers “0000” or “1111. At the end of the WiDi technology configuration go to “Charms”. “Devices”. “Projector”, where you select the TV.

If you use a USB-USB connection, video viewing will not be available, because the standard does not provide video data transfer. At the same time you will have access to pictures, presentations and text documents. So the TV will see the laptop as a USB drive.

To transmit and video data you will need a USB cable and an adapter for it, which is an external video card. Buying it, look at the parameters of the audio signal and support for FullHD format. The adapter is connected to the TV, and the laptop gets the drivers. Then they change the TV signal source to “USB”.

Unlike Wi-Fi, LAN is a wired network connection (via an Ethernet port). This method is relevant if the TV has no Wi-Fi module.

To project the laptop screen on TV the actions are the same as for Wi-Fi connection:

display, your, computer, screen

Diagram of LAN-connection of a laptop computer to TV.

  • They connect the router and the receiver with a network cable. On the network equipment is configured Dynamic Configuration Protocol DCHP. If this is not done, the parameters are entered manually on the TV set.
  • A laptop is connected to the same network (using wire or wireless technology).
  • They install “Home Media Server” software on their notebooks, one of the functions of which is outputting content to TV.
  • Access to folders.

That’s it, the connection is there, you just need to select the content that will be broadcast on the big display.

Popular connector found on newer televisions, PCs, and DVD players. The signal transmission is analog, but without sound. The video quality is not bad at all. 1600 x 1200 pixels. Often this port is labeled as PC, which implies connection to a notebook screen or PC monitor.

To play and sound, buy the adapter for “tunes”. Another option is to make the sound output through the laptop speakers (speakers can be connected to it).

To form a color picture, the system reads 3 signals: R. red, G. green, B. blue. If this connector is used for image output, then it must also be on your TV.

RGB interfaces came along after SCART (the latter was replaced because it was not suitable for TV sets with slim bodies). It is usually found on older models of TV.


European standard for analog and digital signal transmission. It differs in specifications (for sound, video, and control elements). The advantage of SCART is the ability to connect a high-quality RGB video source to the TV (bypassing the intermediate encoding).

Connecting a Laptop to TV via HDMI Cable: tips and tricks of setting up

HDMI stands for High Definition Multimedia Interface. That is a high-definition multimedia interface. Physically, it represents two devices connected by a cable. In our case, it connects a notebook and a TV. Naturally, you need both of them to have HDMI ports. Before you put the laptop screen on the TV, you should know that there are a few versions of the interface, and the technology is constantly evolving. Depending on the version, this changes the capabilities of the interface in terms of resolutions supported, bandwidth, and other parameters. The latest current version, released in early 2017 2.1.

Types of HDMI cables

There are three basic form factors, which can perform HDMI cable. The first is the simple Type A, which has 19 pins and is used in full-sized devices. computers, TVs and set-top boxes. This is the most common type. Mini-HDMI Type C. a more compact connector, which is used in no less compact devices. smartphones, tablets, netbooks and sometimes graphics cards. It also has 19 pins and its characteristics are in no way inferior to its “big” brother.

A variety of connectors. Micro-HDMI Type D. the smallest connector in the whole family. Despite its size, it also contains 19 contacts and is fully compliant with the specifications. Along with the mini-version, it is used in smartphones, tablets, camcorders and other portable devices. Actually, there are two more types. B and E.

The first one is only in the official specification, and it has never been used in real devices, since it has 26 pins and is quite large. The second is quite rare. it is used in car multimedia systems. Equipped with 19 pins and has additional shielding to protect against interference from other devices in the car.

There are a huge number of adapters and adapters for other types of connectors that allow you to display images from a laptop via HDMI, for devices such as old TV or PC.

Connecting Your Laptop to a TV with HDMI

There is nothing unusual or complicated about the connection itself. The only thing before you connect your laptop to the TV through HDMI, it is advisable to make sure that both interface versions meet the parameters of the data being transferred.

Where is the HDMI Input on your laptop computer and TV?

On televisions, the connector can be either on the back or on the side. It is not difficult to detect it, because it is unique and you cannot connect another cable to it.

The connector is usually labeled, so it’s easy to find. The HDMI input on a laptop is also not particularly standardized, so it could be anywhere. But most often it is found on the back of the device.

Setting up your TV to connect with HDMI

To switch the TV set in the HDMI Receive mode, you have to explicitly specify this in the menu. Usually there are buttons like Source or Input on the remote. In the TV menu, look for “Source” or “Datsource” items. Naturally, you must adjust the settings after the HDMI cable is connected to the TV and laptop.

How to Set Up and Turn On HDMI on Your Laptop

If on TV it is enough to simply specify the signal source, then on PC sometimes you will have to reconfigure the connection a little bit. Before you connect your laptop to the TV, you can select the type of display. Usually by default it will just duplicate the source screen. But you can also specify other types. In versions of Windows 7 and higher, this can be done by pressing the Win P key. This will immediately open a window where you can choose your connection options.

Calling the projector connection menu. There are only four of them:

  • only computer. The signal will not go to the TV, but only to the laptop screen;
  • duplicate. The TV screen will look exactly like the PC screen;
  • expand. This type adds another screen on which it will be possible to run e.g. a video or open a website separately, while another application will be used on the laptop;
  • Projector only. The signal will not be repeated on the PC, but will only go to the TV.

TV resolution is usually adjusted automatically. But you can also change it manually in the screen settings of your operating system.

Setting up the sound transmission from the laptop to the TV

As we know, HDMI is also capable of transmitting sound. But this does not always happen in practice. In order to switch the sound, you need to refer to the sound settings in your operating system. To do this, simply right-click on the speaker icon in your system tray and select “Playback Devices.

Sound menu in the system tray. A window will open that will display all possible devices capable of outputting sound. The connected TV set should be among them. Right-clicking on it and choosing “Use as default” will switch the sound to TV.

What should you do if your notebook does not connect to the TV through HDMI?

Yes, connection problems can occur, but they can and should be dealt with. Let’s look at the two most common cases.

Laptop does not see the HDMI cable from the TV set

This situation can arise in only two cases: physical malfunction of the cable or connector, and a problem with the video card drivers.

The cable also has its own strength limit, so it can get damaged. Determine if the wire from the laptop to the TV is really damaged, you can try to connect another. Also you need to check the correspondence of the versions and pick up the cable of the corresponding version. It is more complicated with the connector, it is quite difficult to establish whether it is really the case at home. The only way is to try to switch the cable to a different connector. It is easier with video card: you need to update drivers or on the contrary roll them back to the older version.

The TV does not see the laptop through HDMI

There may be a few reasons why the TV does not see the laptop through HDMI, too. The first thing that comes to mind is the wrong signal source. On some models, with 2 or more connectors you can get confused and choose the wrong one. It is worth checking the correct choice. It is also possible that HDMI can not work properly due to the Smart TV. The situation is rare, but it still happens. It is worth trying to update the software. In all other cases, the suspicion can only fall on a faulty cable or the connector itself.
