How to display a laptop screen on LG TV

We connect the laptop to the TV via HDMI and Wi-Fi

Probably, many owners of portable computers had a desire to display an image from their laptop to a display with a large size and resolution. Such a screen is better for watching high.Quality photos and videos, and the graphics of modern games on it will look more beautiful and realistic. The most obvious and simple option for solving the issue is to connect a monitor from a stationary computer to a laptop. However, the possibility of conjugation with PC also provide for all the latest models of televisions operating under the control of their own operating systems. In this article, we will just tell you how to connect a laptop to the TV with a wired method and without the use of wires (via Wi-Fi). We draw attention to the fact that we are not talking about a simple broadcast on the TV video and photo from a laptop, but about the full duplication of the desktop and all the functionality of Windows, T.E. Using the TV as another monitor.

The HDMI intenses today is one of the most common means of communication of digital devices. With it, sound and video in high quality and with minimal losses can be transmitted with it. Almost all modern models of laptops and TVs are equipped with HDMI connectors. Other integers. VGA, DVI, Scart. Are also used quite widely, but the inputs/outputs of such formats are far from all devices. For example, you will almost guaranteedly find the same DVI on any video card or monitor, but on laptops and TVs it is most often absent. Also, some TV may not have a VGA connector, although on laptops it is without fail.

We’ll say right away that there is no much difference with which wire to connect the laptop to the TV. Whether it is HDMI, VGA or DVI, the sequence of actions and the final result do not differ much. The only thing must be taken into account that the DVI and VGA intenses are able to transmit only the video signal, so the sound will have to be brought up using a separate audio cable.

Wiring and setting up wires

So, let’s begin. We will connect the HP laptop with a pre.Installed Windows 10 system to the LG TV, which operates webos. This is what HDMI connectors look like:

For connection, use the HDMI cable 5 meters long. His photo is given below.

The connection is carried out with the equipment turned off. We stick one end of the cable into the laptop connector, the other into the HDMI 2 TV connector.

Turn on both devices and wait for Windows loading on a laptop. As for the TV, while he broadcasts a television program (the antenna cable has not disconnected). We take the television remote control and find the control button of the signal sources. It is usually called Source or Input.

Click it and in the menu TV screen, select HDMI-2.

After some thought, the TV should display the laptop desktop.

In our case, he slightly went beyond the boundaries of the screen. To eliminate the problem, it was necessary on the TV to go to the settings (Settings button), then select the “screen” item and set the “screen format” as “source”.

Now the image fit perfectly into the boundaries of the TV screen.

Display setting in Windows 10

We click on the desktop with the right mouse button and in the context menu, select the “screen parameters” item. The settings of the displays can be done directly on the page that opened or by moving to the extended parameters at the link “Additional screen parameters”.

In the drop.Down menu there are several options for the work of the displays: “Duplicate these screens”, “Expand these screens”, “Show only 1”, “Show only 2”.

The default duplication mode is active. This means that the same on the screens of the laptop and TV are displayed the same. The second option provides for the ability to transfer the working windows of programs between displays and broadcast its own information on each of them. The purpose of the last two modes is understandable. The picture will be displayed only to one of two screens, the second will turn off.

Here, in the parameters, there is an opportunity to set the resolution of the screens and make some other settings.

We will not focus on them, everyone will be able to experiment himself and adjust everything for himself. We completed the main task. We connected the laptop to the TV through the HDMI cable.

Display setting in Windows 7

The above information on the configuration of displays is relevant for the Windows 10 system, in which the screen settings are made through the utility parameters. In Windows 7, all actions are performed in the control panel, although the essence of this does not change. Let’s switch to the desired configuration page by clicking on the desktop with the right mouse button and selecting the “screen resolution” item.

Methods for displaying the image from the laptop

Connection is divided into wireless and wired. The cable should not always be identical to both of its sides: there are a large number of adapters for different connectors.

Deficiency of wireless connection, which immediately catches the eye. The possibility of an unstable signal. And in the wired. The presence of a wire. It can be short or interrupted somewhere inside, from which there will be no connection, and outwardly the cable may be whole. But the disadvantages can be found in absolutely everything, so do not focus on this, we better move specifically to methods.

Wi-Fi connection

Tvs made according to modern standards have DLNA technology. Its essence lies in the possibility of data transmission inside the home network. This is carried out not only in cable, but also Wi-Fi. In the second case, both devices must be connected to the network.

By default, TV will be able to use only folders with overall access. To fix this, go to the laptop settings and go to the “Network” item. There is a common access to the entire repository. However, in this case, you will lose the safety of your information.

So, anyone who gets access to your Wi-Fi network will be able to use your data. But you can make a “visible” one folder that is currently needed.

It is much better and more convenient if the TV is equipped with Miracast or Intel Widi technology. Turn them on on TV and you can connect with the laptop by wireless. This is done as follows:

  • On the laptop with the right mouse button, click on an empty place on the screen.
  • The menu will appear in front of you. At the bottom of the list there will be the “Screen Parameters” tab. Click on it.
  • In the window that appears, foxing the “displays” menu down, find “connect to a wireless display”. By turning on the mode, a new window will open, it will show all the screens to which you can connect to transmit an image. Select the right device.

Having done this, on the TV display there will be the entire laptop desktop, which will forget about the small laptop resolution.

Transfer the picture from the laptop to the TV, you can by means of HDMI cable. First, make sure the connector is on both devices so as not to make a mistake with the purchase.

After determining the ports, you can connect. This is done like this:

  • Insert one end of the wire into TV and the other into a laptop.
  • On the TV remote, open the menu through which the signal source will be determined.
  • Select “HDMI”.

Ready. Now you need to configure the resolution on the laptop. When the laptop finds a TV, two translting options will be offered. Duplicated, divided or using the second screen as the main.

Ready. Now you need to configure the resolution on the laptop. It happens that after the connection, the picture is displayed fuzzy. It means that the case is in the ratio of the parties. Go to the screen settings and select the optimal settings appropriate to the TV.

Pretty outdated image transmission. When developing this connector, DVI was designed to project a video file on digital devices. He is “Father” HDMI. Only though older, the sound cannot convey. From which he significantly loses its significance. You will need the Mini-Jack connector to broadcast audio.

For connecting, the instructions from HDMI, which were set out above, is suitable.


Not the most reasonable way of connecting, since the quality of the transmitted image leaves much to be desired. Broadcasts video files of clarity 576i and 480i, which of course is not enough, if we talk about modern formats. Over, it will take an adapter from S-Video to RCA. Sound is not supported, similarly with DVI. To appear, use the Mini-Jack connector.

USB cable

You can also move the images from the laptop to the TV through USB. But if we are talking about the video, then immediately discard this option, since it does not imply the transfer of video content. Images, various presentations, documents. Do not calculate more.

LAN-port used to transmit Internet connection. This option is suitable if the TV is not equipped with a Wi-Fi module. The whole thing is connected in this way:

  • Connect the TV to the router with the Internet using a network cable.
  • Also do with a laptop. Here you can connect by Wi-Fi-it does not matter, the main thing is that to one network with a TV.
  • The laptop will need to be installed appropriate software for translating. Suitable application “Home media server”. It has a fairly simple installation, understandable at an intuitive level.
  • Allow me to use the desired folders by opening access to them.

Ready. Enjoy the picture from the laptop to the TV.

The lack of this connection is the absence of sound, when it is mating. In order for the sound to appear, you can use the adapter with “tulips”, or all the same mini-jack. In order not to bother with audio, the sound is left on the laptop by connecting the columns to it. It is also possible through the built.In dynamics of the laptop.

Do not forget to choose the right resolution so that the viewing process gives maximum pleasure.

It is expanded and translated as “red green blue”. This connector is calculated as SCART replacement, since it is already very outdated and modern manufacturers have abandoned its use. But RGB also did not go far. More often it can be found on old.Generation TVs. Can be combined with all the same Scart or “tulips”.

Connection via Scart

European standard that can transmit both digital and analog signal. Audio, video. Everything can do.

In order to project images from a laptop to a TV, it is better to use an adapter from VGA to Scart. There is an explanation for this. It is SCART on TVs most often on TVs, and on VGA laptops.

How to connect the device with Smart TV depending on the OS?

A special function on the Windows Media Center laptop will need to activate. This process depends on the type of operating system installed on PC.

Windows 7

The connection algorithm to TV Smart is as follows:

  • First go to the Start menu, then find the search there.
  • Enter the Windows Media Center program.
  • A list will open in which you need to find a “media reception”, and then. “installation of media recovery”.

Then just carefully read the instructions that will explain in detail how to display and select files for viewing on the screen.

Windows 8

How to make TV second monitor PC with Windows 8 OS without wires via Wi-Fi:

  • Dill the mouse cursor to the upper right corner.
  • In the menu that opens, find the search.
  • Keep the name of the same Windows Media Center program.
  • Open and run.

Windows 10

This OSC has a function of transferring files to a large screen, and therefore it is more convenient to work. How to use TV as a second computer monitor via Wi-Fi:

You can choose a simplified option: click on the file with the right mouse button and find the “Put on the device” function. Knowing the details of your OS, there is no need to download a special paid software for synchronization of the laptop and TV.

Methods of connection

We will analyze by points to connect a laptop to a TV without a wire to choose the easiest way.

DLNA network

To use DLNA on the TV, you need:

  • Connect a TV, a smartphone, or a tablet to one network via Wi-Fi. You can do this on both devices by going into their settings and completing a wireless network search. Select your home wireless network from this list and enter your wireless network password. In the case of smart TVs, you can also use the local network cable to connect them to the router.
  • DLNA application download to your smartphone. For streaming the contents from the smartphone, the DLNA application should be installed on it. One of the most popular DLNA applications is Bubbleupnp, which can be downloaded from Google Play Store for free. Some smartphones are also supplied with pre.Loaded DLNA applications.
  • Choosing a device. As soon as you download the Bubbleupnp application to your smartphone, you will see a screen with four menu below. Now Playing, Playlist, Library and Devices. Before choosing a file, you need to choose a device that you want to transfer the stream to. You can access this list by clicking on the devices presented on the main screen screen. Select your TV from the list of renders. If you broadcast content from your portable device, then you can choose this. If you have a separate network drive, you can also choose a stream gear from it.
  • Streaming multimedia on TV. As soon as you select the device, you need to choose the content that you want to play on it. You can access all media files, first choosing source from which you want to play. Bubbleupnp shares all your songs, videos and images in folders. You can click on a file that you want in stream mode. As soon as you select the file, the application will begin its flow to the TV. You can choose one file or create a play list to your liking. You can also control the volume of the TV using the volume control keys available on your phone. In this way you can quickly and simply decide how to transmit the image.

You can also use DLNA to connect a laptop to a TV and streaming photos to TV. Some smart TVs do not even need a router as a means for streaming multimedia files from a smartphone. To do this, you will need a smart TV and a smartphone supporting Miracast. This technology uses Wi-Fi Direct for streaming content and is great for short distances, for example, in the living room. Miracast also allows you to duplicate your smartphone screen on your smart TV. This means that you can watch movies, music, as well as play games and use applications on the big screen. Samsung has implemented this method when creating Smart-TV technology.

Duplication of the screen using Widi Miracast

Windows 10 offered the possibility of duplicating the screen to any adapter or device (streaming device, TV), compatible with the popular Miracast standard, from the moment it is launched in 2015. Now the Microsoft OS allows your computer to become a wireless display, receiving Miracast signals from a phone, tablet or other Windows 10 laptop or a desktop computer.

If you have a Windows 10 computer connected to the TV, it can now be used as a wireless display for a phone or laptop. When you mirror with Windows 10, you can expand, not duplicate the screen so that you can, for example, play the film on the acceptance display while sending emails to the main. Just imagine that you take a tablet from Windows 10. Put it next to the laptop and use it as a second monitor on the road. The same can be done with the TV.

While most modern devices with Wi-Fi are able to send a miracast signal, the compatibility of old models at best is small. Sometimes you need to try to broadcast the screen three or four times before the process works. So gain patience. If you accidentally turned the screen. Trying to expand it, we have a quick solution for this.

  • Open the center of action. It is represented by the icon of “replicas” in the lower right corner of the screen.
  • Click connect.
  • Click “project on this computer”.
  • Select “Available everywhere” or “Available everywhere in protected networks” in the opening menu.
  • Select “only the first time” or “every time” in the section “Ask to project on this computer”. It is recommended to choose “only for the first time” if you are not worried that some fraudster is going to capture your phone and project on your computer without your permission.
  • Next, you need to synchronize the laptop. It is better to leave “Demand the PIN-code for the conjugation” disconnected, since you still have to give permission on the receiving computer. You can also decide whether you want your PC to receive a projection only when it is connected. So you can knit devices.
  • Click yes. When Windows 10 will warn you that another device wants to project on your computer.

The Windows Connect application will start in its own window when the connection to Smart-TV begins. You can drag, change the size or expand the window. We found that the video is played smoothly in the connection between Surface Pro 4 and ThinkPad T440S. In addition, if the sending device is a PC with Windows 10 OS and this is allowed, you can use the keyboard and mouse on the acceptance computer for remote control of the sender.

How to reflect the Windows 10 screen on another device

Here’s how to broadcast your screen from a sending device if it is a computer with Windows 10. Android devices have various wireless display menu.

  • Open the center of action.
  • Click connect. A list of available reception devices will appear, and your second computer should be on it.
  • Select the receiving device. You may have to wait a minute or longer to connect the devices. It can also fail, and you will need to try again.
  • Set the “allow entry” checkbox. If you want the receiving device to control your PC using a keyboard and mouse.
  • Click “Change the Projection mode” and select “Expand” in the menu that appears if you want to use a wireless display as a second desktop, and not a mirror of the current desktop.
  • Click disconnect. When you want to break the connection.

Connection using Wi-Fi Adaptors

If you were not able to connect the Wi-Fi TV laptop, but this method for you remains more preferable, compared to connecting by HDMI, you can try connecting a laptop with a TV using an intermediary-TV prefix on Android or Wi-Fi Dong, For example, Google Chromecast. In this case, you simply need to connect in a Wi-Fi network organized by this adapter and broadcast the signal on it precisely.

However, such an extravagant solution will be justified if the connection of the cable is almost impossible, such as for for example, for a video project suspended to the ceiling. It is much cheaper and more reliable to use HDMI connection and connect the laptop on the TV through the corresponding cable.

Wi-Fi Direct TV connection

This function works well on modern TVs starting with the 5th generation, in which manufacturers have already introduced unified drivers of wireless direct connection. This.N. Connecting the second wireless monitor, where the TV acts as an external display device of everything that happens on the screen of your mobile device, such as a laptop or smartphone.

In the first case, it is necessary to have Windows 7, 8 or 10. The home network is not required with this connection, and authentication and connection is carried out through a request for connection on the screen of the TV itself.

This connection is convenient in that you can see on the big screen everything that is done on the screen of your PC or laptop, including work in a browser, watching photos or videos, as well as the game process. The only minus here is a small delay in displaying content on TV and a slightly smaller number of colors than on the PC display.

Performing wi-fi direct is quite simple. To do this, turn on the TV and laptop. On both devices, Wi-Fi adapters should be activated.

Now on a laptop with Windows 10 go to “Start. Parameters. System. Display” and on the right side in the “Several Display” section, click on “Connect to a wireless display”.

A vertical curtain with the “connect” menu and a list of detected devices will appear on the right side. In our case, this is Samsung 6 Series. Click on the selected model, after which on the TV itself, agree with the request for connection.

It should be noted that the connection may not occur with the first or even from the second attempt, t.To. The computer needs time to transmit TV encryption keys. But after the TV is connected to the laptop via Wi-Fi, you can broadcast the video at least from another room.

In order to turn off the transmission of a wireless video signal on TV, again click on “Connect to a wireless display” and in the right curtain menu click on the “Disable” button.

How to connect a laptop to a TV via cable?

The connection using the cable is more stable than the transmission of the signal by air, so choose it if it does not reduce the ease of use.

The connectors differ depending on the device, so determine your.

Through HDMI

HDMI ports have most modern laptops. New TVs work through this default standard.

display, laptop, screen

HDMI transfers both the picture and sound. It is able to broadcast the signal with quality up to 1920 × 1080 pixels, with 8-channel sound.

  • Connect the HDMI cable to the connectors of both devices. There may be several identical ports on the TV. Look for the one indicated by the word “in”.
  • Turn on both devices.
  • Find the button on the TV remote control, which is responsible for switching the signal source. It is usually indicated “source”.
  • Select “HDMI”.
  • The picture will automatically appear on the TV screen.

If this does not happen, determine the display through the settings of the operating system:

Through VGA

VGA is an analog standard that is rarely found in new laptops. He transfers a video sequence with quality up to 1600 × 1200 pixels.

VGA translates only video, without sound.

Usually the VGA nest is painted black or blue. It can also be signed “D-Sub”.

Connecting a laptop to a TV via VGA:

  • Connect both ends of the wire to the devices.
  • Press the Source button on TV TV. Choose a VGsource.
  • The picture will automatically display on the screen.

If there is no signal, find the display in the laptop operating system. Instructions. Here.


Some laptops, in principle, do not have a video output. This applies to compact models and netbooks. However, you can connect a laptop to a TV through a USB port.

In this case, two methods of connection are used: using an adapter or through a converter.

  • With an adapter. Buy a special adapter that converts a signal for VGA or HDMI port (push off from the TV connector). Connect the adapter to USB. On the other side of the adapter, attach one of the tails of VGA or HDMI wires. The second end of the cable. To the TV. Signal setting is automatically.
  • Through the converter. This method can be considered simultaneously wired and wireless. Buy a special converter that consists of two components: Wi-Fi transmitter (to the USB port) and converter (to the port of the TV). The laptop will automatically define the transmitter as an external video card. Audio and video signal to the converter will come from it, and he will transmit the picture and sound to the TV on the wire. Typically, three ports are mounted in the converter at once: VGA or HDMI (to choose from) and jack for connecting sound.

The signal on the TV is also connected. Through the Source button on the remote control.

The quality of the signal is not lost if the adapter is used.

In the case of the converter, the maximum distance from the laptop to the TV is up to 10 meters without barriers.

Through tulips

One of the oldest ways to connect a laptop to a TV is an analog gear through a RCA cable. These ports can be found on very old models and on new thin displays.

Typically, the wires of “tulips” are equipped with three outputs:

But there is one problem: RCA is not put on laptops. In this case, you can use two methods:

Through the adapter HDMI. RCA

  • Connect the laptop and adapter using HDMI cable.
  • Through the triple RCA, connect the adapter to the TV.
  • On the remote control, press the Source or Input button to configure the image source.

Via vga adapter. RCA

The adapter for VGA will be a little cheaper than HDMI, but the quality of the picture will suffer from this.

  • Connect the laptop to the adapter via VGA wire.
  • Connect the adapter to the TV using standard RCA cables.
  • You can find a signal using the Source button on the PDU.

You can assemble a design of two adapters. First connect the adapter from the USB to VGA, then stick the adapter from VGA on RCA into the circuit.

A similar method is suitable if there is only RCA inputs on the TV, and only a USB port in the laptop.

How to transmit an image and video from a computer to a TV on Wi-Fi (DLNA)

This method of wireless television connection is considered the most common. This and all subsequent instructions are written for Windows 7, 8 operating systems.1 and Windows 10

How to share your PC or laptop screen wirelessly on LG TV?

If the TV supports Wi-Fi Direct, the router is not required-you can connect directly to the television network. To connect, you must go to the corresponding TV menu.

DLNA function can be used to play content without setting up the DLNA server. Condition-computer and TV should be on one local network-connected to one router or via Wi-Fi Direct.

  • Set the dlna server on a computer. You need to open access to the right files. To do this, in the parameters of the network, select the type “Home”. All other folders. With documents, images, music and video become available by default. To open access to a specific folder, just click on it with the right mouse button. Select the “Properties” and “Access” tab in the context menu.
  • Turn on the overall access. The fastest option is to open a conductor and select “Network”. If after that information appears that the detection of the network and access are disconnected, click on the message and follow the instructions that will appear.

If this message did not appear, and computers and multimedia servers are displayed instead, most likely DLNA is already configured. Otherwise, you have to configure the DLNA server.

When the DLNA is configured and connected, open the TV menu and see which devices are connected. The algorithm of actions depends on the brand of the TV, for example:

  • In Sony Bravia, click the Home button, and then, choosing the desired section. Music, films, images, see the contents of the computer;
  • In LG, select SmartShare, there you will see what is in the folders, even if you do not have this program on your computer.

In TVs of other brands, you have to perform approximately the same manipulations using the relevant programs.

When the DLNA is connected, then go on the computer to the desired folder and, clicking on the video file in the conductor, select the item “play for””. Instead of points, the name of your TV will be indicated. Next, the program is launched by Wi-Fi Video signal-from a computer/laptop on TV.

Even if the TV has support for films in MKV format, they will not function for them in Windows 7 and 8, so they will not be visible on the TV menu, the easiest way to eliminate the problem is to rename these files in AVI on a computer.

Possible difficulties in transmission

Modern technologies amaze with the simplicity of their actions. Attentive familiarization with the instructions will help you choose the correct connection method and ensure a productive pastime
