Cable for connecting a laptop to an HDMI TV. Why there may be no picture on TV


To connect your portable laptop to your TV via an HDMI interface you do not need professional knowledge or the help of a specialist. All you have to do is carefully follow our simple recommendations, and high quality video With multi-channel sound you are guaranteed. So, what will be required of you?

1. Connect the TV to the laptop with an HDMI cable

To do this, you will need a cable of the required length, type “HDMI-HDMI”, that is, with the same connectors at both ends, which does not require the use of any adapters. If you want to enjoy 3D content on your TV or watch videos in 4K format, then purchase a cable version no lower than HDMI 1.4.

Before connecting the cable to the sockets on the TV and laptop, do not forget to disconnect both devices from the power supply. But don’t just press the Off button, but rather remove the plug from the socket to reduce the likelihood of ports burning out. There can be several HDMI connectors, and they can be located in different places of the device (back, side), but they are always labeled and look special, so you can’t go wrong.

After connecting devices to the power supply (first turn on the TV and then the laptop), an image does not always automatically appear on the TV screen. It is possible that you will see a message like this: “ Weak signal or no signal”, “Cable not connected”, “Check the cable connection and signal source parameters”. IN in this case should be done additional settings.

2. Set up your TV and laptop

TV settings. On the TV remote control, find and press the Source, Input or HDMI button (depending on the brand). In the drop-down on-screen menu, find the number of the HDMI port to which we connected and select it Enter button(OK). After this, it should appear on the TV screen mirror reflection laptop desktop.


Laptop settings. You can configure your laptop for optimal multimedia transfer using hardware and programmatically. In any case, before setting up, you should make sure that the most appropriate settings are installed on the laptop’s sound and video cards. fresh drivers, which it is advisable to download from the manufacturer’s official website. Besides, graphics adapter must support transmission digital audio High Quality HD Audio.

Hardware method. Simultaneously pressing the required number of times on the Fn button and one of function buttons with the image of the monitor (usually F3 or F8) on the laptop keyboard, select the option of using the TV screen: duplicate screen, extended screen, external monitor. It is preferable to select the screen duplication mode, since this makes it more convenient to make all the necessary settings.

Software method. It is more flexible and effective method settings. By right-clicking on a free field of the desktop, we cause the appearance context menu, in which we select the “Screen resolution” item (for Win7) and go to the screen settings menu. Here we can choose the appropriate option for using the TV screen, and also set the required resolution.

For WinXP, select “Properties: Screen” - “Options”. If you choose the option of duplicating (cloning) the screen, then the resolution on the laptop’s video card should be set to no higher than the resolution supported by the TV screen.

If, after trying to connect a laptop to a TV via an HDMI interface, certain problems arise with video display, then you will have to go to the settings menu for the laptop’s video card, right-clicking on an empty space on the laptop’s desktop and selecting the item we need. You can also fine-tune the resolution settings, frame rate, screen aspect ratio and color scheme that suits you.

Computer technology is constantly developing, new devices are being developed that improve the quality of information processing. No wonder that modern laptops equipped a huge amount various connectors. Let's look at all the ways to connect a laptop to a TV.

  • output image to big screen;
  • organization of presentations;
  • communication via Skype and other similar services.

Let us dwell in detail on the first point. By connecting the laptop to the TV, the user will be able to watch videos online and run files stored on the laptop’s hard drive. By and large, this is an imitation Smart functionality TV. At the same time, the cable costs much less than a “smart” TV.

There are several ways to connect a laptop to a TV. This is very easy to do, but first you need to familiarize yourself with the available interfaces. After connecting the connectors, additional configuration is carried out.

Connection via HDMI cable

This is the easiest way to connect a laptop to TV. The only catch is availability HDMI cable But, it doesn’t come in the basic package, so you’ll have to buy an additional cable. However, it is inexpensive (from 150 rubles or more), and it is also universal, that is, it is suitable for both Samsung and Sony devices.

Mostly users prefer this type of connection not only because of its simplicity. The fact is that this method allows you to use the maximum resolution.

Advantages:

  • All TVs and laptops are equipped with a connector;
  • easy connection;
  • low cable cost;
  • one cord is responsible for transmitting sound and image;
  • Full HD resolution.

There are no disadvantages.

HDMI connectors are found on absolutely all laptops that have been released over the past few years. The exception is the cheapest models.

Now you should find a similar interface on the back of the TV. If there is no output for this cable, then you will have to additionally purchase adapters or use alternative method connections.

There are no special instructions. Simply insert the cable into the connector of your laptop and TV. However, not every user knows how to properly configure the connection. We've sorted out the hardware aspects, so it's time to move on to the software component.

To go to the screen management section on the laptop, you need to right-click on the desktop, and then select “Screen resolution” from the context menu. As a result, a window will open in which you can select the method of use. additional monitor. The system offers the following options:

  • 2 screens as a single space, that is, the desktop will expand;
  • TV serves as a second monitor, you can work and watch a movie at the same time;
  • image cloning - the same image on the laptop and TV;
  • additional options - functionality directly depends on the power of the video card.

In the same section, you set the video resolution for display on a TV monitor. Maximum value for HDMI connections– 1920x1080 pixels. This means that you will be able to watch movies in Full HD.

As for setting up TV equipment itself, everything is much simpler here. To begin, open the software menu and select a signal source. We choose among the proposed HDMI options with the number to which the cable is connected. This completes the connection setup.

DVI cable

Not much different from HDMI. The DVI interface is modern. The problem is that this output is available on many computers, but is extremely rare on laptops. In such cases, you can connect the laptop to the TV using a DVI cable using an adapter.

Advantages:

  • easy connection;
  • Full HD resolution.

Flaws:

  • Rarely found on laptops.

When connecting a laptop to a TV via a DVI cable, the user will be able to watch video content with Full HD resolution - 1920x1080 pixels, in fact, as is the case with HDMI. Connection specifics do not change depending on the equipment manufacturer. That is, you can easily synchronize an Asus laptop and a Sony TV.

Some modern devices are equipped with an updated Dual Link DVI-I digital interface, which differs from the standard connector in increased screen resolution - 2560x1600 pixels.

Despite the fact that this digital signal, the sound will still have to be connected separately.

Scart

The main advantage of this digital interface is its versatility. The connector is found on both older models and new ones. The Scart output provides high-quality audio and video transmission, but to use this type of connection you need an adapter cable, because laptops are not equipped with such a connector.

Advantages:

  • versatility;
  • audio cord included in the basic package;

Flaws:

  • An adapter is required since laptops are not equipped with such a connector.

You can connect your laptop to your TV using VGA and Scart. It should be noted that the audio cord for transmitting sound to the TV is included in the basic package. Scart is mainly used to connect older TV models. Therefore, if you have new model, then it is more advisable to give preference to the HDMI connection.

VGA output

This interface is found on many laptops, but is much less common on TVs. If there is still a VGA input on the back panel of the TV, then you can use the most common cable to the screen from a PC to connect.

If there is no connector, then to connect the laptop to the TV you will have to use adapters: VGA-HDMI, VGA-Scart or any other of your choice.

Another feature of this connection is that the VGA connector transmits exclusively video signals. To transfer sound from a laptop to, you will have to get an additional cable.

Mostly VGA connection used to view photos on a large LCD screen. As for resolution, the maximum parameter is 1600x1200.

This type of screen switching is also suitable for video games. After all, you can play with headphones, so there is no need to use an additional cable.

Sometimes this interface is found on netbooks, for example, on Asus Eee PC, Acer and others. Therefore, in order not to watch movies on a tiny display, netbook owners connect the device to the TV using VGA. It is also advisable to transfer the sound to TV speakers, since they are more powerful.

Advantages:

  • a high resolution;
  • ease of connection;
  • The interface is available on many laptops.

Flaws:

  • a separate cord is required for sound transmission;
  • Not all TVs are equipped with a VGA interface.

Overall, HDMI is a more practical solution.

RCA and S-Video

As a rule, these connection types are equated to the same group due to the fact that they are used extremely rarely. RCA and S-Video interfaces are a relic of the past, so they are often found on older equipment.

Laptops with such outputs have been out of circulation for quite some time. Therefore, connecting a laptop via RCA or S-Video - last resort, in case there is simply no other option. To connect a TV to a laptop using these interfaces, special adapters and converters are used.

Advantages:

  • found on older models.

Flaws:

  • the technology is noticeably outdated;
  • image quality leaves much to be desired;
  • There are no laptops with such interfaces.

The RCA connector is the well-known tulips with which the first game consoles and the first video cassette players. If you don't know how to watch a movie from a laptop on a TV that's over 10 years old, then use an adapter. The tulips are inserted into the TV panel, and the converter into the laptop connector.

Naturally, an RCA cable is not capable of transmitting high high quality image. In this regard, this option is used exclusively in desperate situations.

Connection via Wi-Fi or Ethernet

How to connect a laptop to a TV without HDMI? Of course, the most convenient and practical option is a wired or wireless Internet connection. Firstly, with Wi-Fi there is no need to purchase additional cords. Secondly, you can work with media files stored on the laptop directly from the TV (DLNA technology).

Advantages:

  • in the case of Wi-Fi - no cords;
  • high image quality;
  • simultaneous broadcast of video and audio content;
  • practicality.

Flaws:

  • Not all TVs are equipped with a Wi-Fi adapter and an Ethernet input.

Even if the computer is located in another room, this will not be a problem. The main thing is that it is turned on. You must also first configure access to the folders that contain files to be viewed. As a result, you will be able to view photos, videos and even listen to audio tracks. This connection is especially important if you previously purchased a speaker system.

To transform a regular TV into a Smart TV, you need to use Wi-Fi router, who will actually act as an intermediary. Connect your TV and laptop to the router, after which you can control the device with a regular remote control. Moreover, the TV can be connected to the router via a network cable, and the laptop via Wi-Fi and vice versa.

Some manufacturers have developed special software for these purposes. For example, LG has pre-installed installed utility Smart Share. Connection to Samsung Smart TV is carried out via AllShare program. Sony devices also have proprietary software - VAIO Media Server.

Using this principle, you can connect a netbook to a TV and even a smartphone. The main thing is that the device has a built-in wireless network module.

Not all TV models are equipped with Wi-Fi. However, if it is not there, you can use network cable. If there is no Ethernet input, you can buy an external Wi-Fi adapter. When choosing a module, do not forget that the components are from different manufacturers not interchangeable. Accordingly, buy an adapter according to the brand of television equipment.

The TV is connected to the router according to the same principle as any other devices. Just find the “Network” or “Network Settings” section in the main menu. Select your network, enter your password and you're done.

Using a wireless monitor

By connecting the cables to the appropriate connectors, you can unnecessary problems use the TV for video games or online services.

WITH wireless technologies the situation is somewhat different. However, on most Smart models TV released later than 2013, there is support for the new Intel technologies WiDi or Miracast. It’s still too early to use them for games. The essence of the above technologies is that you can transfer images from the screen of a laptop, smartphone or using WiFi connection.

However, there are several significant shortcomings. The key disadvantage is that the device connects with a delay. According to technological fundamentals, the image is compressed and transmitted to the TV screen via a wireless connection.

The transfer of information is carried out quite quickly. For Internet surfing, viewing photos or videos, the speed is more than enough. However, if we talk specifically about active games, the delay is noticeable to the naked eye, as a result of which minor lags occur. Therefore, gamers should still refuse wireless monitor in favor of an HDMI connection.

To use Miracast WiDi, the built-in technology support is not enough. It is important that the laptop works Intel platform latest generation. There is no support for other platforms.

Setting up a TV and laptop

It is important not only to connect, but also to set the optimal parameters for the TV and laptop computer. The setup process may vary slightly depending on which model you are talking about.

TV software setup

When all devices are connected via cable, it is necessary to make the appropriate settings. To begin, open the main menu of the TV and select the input through which the laptop was connected.

For some models, immediately after connecting the cable, the name of the input to which the device was actually connected appears. Activate it, after which you will immediately see the laptop desktop on your TV screen.

Sometimes you have to adjust the connection manually, but there is nothing complicated about it. For example, to select VGA interface, go to the menu and check the box next to PC. For maximum convenience, some manufacturers mark absolutely all inputs with a special icon, by which you can identify the port without unnecessary difficulties.

Many models are equipped with illumination of active connectors, again, this greatly simplifies the search active method synchronization Naturally, there are differences in the settings, since each TV has a special menu.

Laptop setup

Immediately after connecting, configure the laptop in such a way as to display the highest quality image on the screen. This is incredibly easy to do. There are two ways.

Quick option

Press the Win + P combination on your keyboard. A menu with active connections will open. Select the required option, after which the changes will take effect. There are 4 modes software settings connected devices:

  1. Display 1 screen – TV or laptop.
  2. Screen duplication – identical information is displayed on both displays.
  3. Screen extension – both displays function as a single desktop.
  4. Show only the TV screen; on the laptop the display turns off.

The choice of method is carried out in accordance with the objectives. When connecting an additional monitor, the first option will be preferable for setup.

Method No. 2

Click on a free area of ​​the desktop RMB, and then select the “Screen resolution” section from the context menu. If connected to a laptop additional screen, the “Multiple Screens” section will appear in the menu, as well as the “Connect to a Projector” command.

  • The “Multiple Screens” command will offer the user 4 modes for using connected devices.
  • The Connect to Projector command will open a new menu for additional settings.

These are the main ways to connect a laptop to TV. The options described above are ideal for owners regular TVs, without Smart functions. In principle, if you use HDMI or any other cable, the capabilities are automatically equal to Smart T. You will be able to watch videos online, terrestrial television and listen to music.

Software setting is not prerequisite, but still it is desirable.

So, the task before us is to connect our laptop to the TV via a cable with an HDMI connector. Let's look at a specific case. There is an Asus (practically a laptop, only it does not have a disk drive - but this is not important - as long as it has such a connector). He is shown in the picture on the left. There is an old one Samsung TV, but it also has such a connector. Let's get started. The operation scheme is simple: first we physically connect the laptop and the TV via a cable, and then on the TV we select the signal source from the hdmi cable.

My laptop has an HDMI connector. Here's what it looks like from the side.

There is also a cable with the same connectors.

Now we take the cable and plug it into the corresponding connector of the laptop, that is, we connect the cable and the laptop.

And not really new TV We unfold the Samsung and look at the connectors from the back.

And which hole should I put it in? We are looking for a section HDMI IN, i.e. entrance. (there are 2 such inputs in this section, but I already have one connected - I’m looking satellite TV channels...). And into the free connector we insert the second end of the cable that we connected to the laptop. All. Electrical diagram assembled, all that remains is to run the signal from the laptop via cable. To do this, we need to select the signal source in the TV settings (after all, it can come from both TV antenna, satellite receiver and other devices). You see how many different input connectors there are and you can connect something to each. So, turn on the TV and take the remote control. We point it at our TV.

And press the button SOURCE(which translated from bourgeois means “source”). Those. At this step we choose where the signal will come from. And we see this picture.

Computer technology is constantly evolving, developing new devices that provide high information processing capabilities. That's why modern computers equipped with many different connectors.

Many people are interested in connecting a laptop to a TV in order to use the large screen. Modern TVs endowed with many abilities, they read multimedia files from hard drive, provide Internet access, organize viewing streaming video. But despite these capabilities, they cannot fully perform all the tasks that a computer can perform.

A connected TV to a laptop has many possibilities:

  • display the image from the laptop to the TV, and therefore to a convenient large screen;
  • organize presentations;
  • When communicating via Skype, have a large screen in front of you.

There are several ways to connect a TV to a laptop. This is very easy to do. But first, you need to study available interfaces, determine how you can connect them. After connecting the connectors of these two devices, settings are made.

Modern laptops have HDGA and VGA outputs, as well as S-Video and DVI connectors. The same ports are found on TVs. If the devices have the same type of connectors, then we connect the TV to the laptop with a cable with the same pins. When they are different, you need to buy the appropriate adapter, for example, HDMI - DVI or HDMI - VGA.

Connecting a laptop to a TV via cable does not depend on its model. All TVs are suitable for this: Philips, LG, Lenovo, Samsung, and laptops: Lenovo, Asus or others.

To connect your laptop to your TV, you need to take just three steps:

  1. You need to inspect the entrances and exits. Determine the available connectors and decide which ones will be used.
  2. Select a cable for connection. Perhaps there are no ports of the same type on these devices, then you will have to connect with special adapters.
  3. Configure the operating mode of the graphics adapter.

We connect the cord starting from the laptop, the laptop has the required connector, to the old TV, where there is no such socket, then we select a suitable adapter for it.

How to connect a laptop to a TV using an HDMI cable? This can be done easily, having such a cord and the presence of the necessary ports on two devices. To do this, let's look at how a laptop is connected to a TV via an HDMI connector. This is one of the best ways, providing high-quality video transmission, 3D image format and good audio signals.

The compact HDMI cable is convenient, and its connector does not require additional fasteners. Bandwidth 3 times higher than DVI. A new version The 1.4 cable has ultra-high resolution, its standard length is up to 15 meters, this is very convenient if the screen is large.

Let's consider cable connection from laptop to LG TV. For this you will need:

  • TV with HDMI connector;
  • Availability of a laptop with HDMI output;
  • Availability of HDMI-HDMI cable.

Advantage of HDMI HDMI cable lies in its ability to transmit video and audio signals over a single cord, it has no disadvantages in transmission analog signal like others.

The HDMI connector has a trapezoidal shape. Its input port consists of 19 contact holes. If the TV is new and the laptop is old, it means it does not have the same connector. Then you need to buy a VGA to HDMI convector.

The laptop is connected to the TV via an HDMI cable, all that remains is to configure it by switching the TV channel to the input being used, the laptop display will begin to transmit the picture to the screen. In some models, this happens automatically, or you will have to configure them additionally. And on the remote control of some TVs, for example, LG, there is special button"INPUT". It allows you to switch between video inputs.

After connection, the transmitting signal and sound from the laptop will begin to be displayed on the TV screen. Contact is established with the TV, there is a picture on the TV, the sound is good, without interference, which means everything was done correctly, if not, you will have to press “find”.

The new Samsung TVs have several HDMI connectors, so in the menu you need to set the selected signal source and port number.

How to set up a laptop? To do this, click on the desktop and go to “Screen Resolution”. In the window that appears, select “Display” and indicate the TV you are using.

Set up a Lenovo (or other) laptop in Windows 8 like this: press win+C and select “Device”, and then what you need, namely:

  • "Duplicate";
  • "Expand";
  • "Only the second screen."

VGA cable

Well-known modern manufacturers are increasingly introducing digital interfaces: HDMI, DVI and DisplayPort. That's why all old or budget TVs have a VGA connector.

Connect your laptop to your TV via VGA cable simple, but to transmit sound you will need another additional cord.

How to connect a laptop to a TV with a VGA cable, turn it on in viewing mode and get sound? To do this, press and hold the Fn key, then press F7 (there is a picture with two screens on it), the sound will start playing, but only on the laptop or speakers, if they are connected to it.

Connecting a TV using adapters and convectors is more difficult, but sometimes it is necessary due to the lack of necessary connectors. The problem is solved using VGA-HDMI cable or another, you can always pick it up, and it’s called a “tulip”. Instead of a cord, it is better to purchase a converter, which gives better results.

DVI cable

Digital cable technology makes it possible to transmit images with higher quality. If there DVI connector on the TV, and on the laptop HDMI, then feel free to use an adapter or a combination cable. This interface has three options. The first one is DVI-D, this digital transmission video signal, and the other two in 3D format.

Wireless connection

Wireless Wi-Fi connection is more preferable, it does not require a long cable, which creates inconvenience in the room.

It is possible to connect a laptop to a TV via WIFI, but only the TV must have a modern, built-in adapter (or connected), which has audio and video playback functions, and can communicate with the Internet via WIFI technology.

Is it possible to connect to the TV via USB port, if there is no such built-in Wi-Fi adapter? To do this, install special software, that is, connect the adapter via a USB port, install the receiver on HDMI or VGA TV, and the transmitter is connected to the USB port of the laptop.

Such technologies allow you to connect to your TV wirelessly, and also have fast access to the file library. Display information from others mobile applications, this is a tablet or smartphone.

There are two connection options:

  1. Direct is TV and computer.
  2. At WIFI assistance router.

A direct connection makes it possible to watch movies that are located on the laptop. It is created on it special folder, in which you can place everything that you plan to reproduce.

Router. All settings go through it. But you need to install it on your laptop special program media server, then the TV will recognize all programs and files.

Connect Smart TV to laptop

For such a connection, both devices are connected to the same network; routers are designed for this; when there is none, they use a laptop. By the way, it is advisable to read the instructions that came with the TV, it describes in detail how to connect to Wi-Fi, the steps will be as follows:

  • looking for the settings menu;
  • go to the “network” section;
  • select “Network settings”;
  • indicate the connection type “Wi-Fi”.

Scanning available connections. A list of suggested networks will be displayed on the screen. Select the name of the network. By default, it is called the router.

Now everyone can evaluate all the connectors of their devices. Based on the possibility, choose a way to connect the laptop to the TV, expanding its functionality.

Today, any user using an HDMI cable can also desktop computer to your LCD flat screen TV and then enjoy the enhanced picture. Such a connection is not always successful: for example, it may . But there are times when the computer does not see a TV connected via HDMI at all, although you just purchased the cable from a store where it was extensively tested. Reasons incorrect operation there is a lot of cable, and the search for the true problem must be done consistently.

We carry out diagnostics

What should you do if the TV does not see the laptop via HDMI? Video cards of all modern products support this connection: HDMI on the TV is installed on almost every model. If the connection of the laptop was carried out according to all the rules, but there is still no image, then we connect the laptop to the TV, while sequentially checking all possible problems.

Cable check

Not a single product, even the most reliable brand, is immune from manufacturing defects, especially when assembled by hand. When purchasing, the quality of the image and sound are checked, but they never check the specific connectors and connection sockets on the TV - at best, they make sure that they are present, and even then not all buyers. It often happens that The cable itself doesn't work, although it has not been used for such a long time. You need to connect the same cable, but to another device, if it functions normally, then the reason that the computer does not see the TV lies in the latter. It is necessary to diagnose the TV to recognize similar signals.

Checking the signal source

On remote control control (remote control) press the button to select the external input option. From specific model The product depends on which button on the TV remote control you need to press: “source”, “input” or “HDMI” (LG, Sony or Samsung). After pressing, a menu appears on the screen with detailed list of active inputs. Select and confirm by pressing OK or Enter, namely required input, into which the cable coming from the laptop was previously connected.



Working with the monitor

If the laptop does not see the TV when simultaneous connection several monitors, then it is necessary to carry out additional settings. These simple manipulations Any user without special education can perform:

  • hover over any free place desktop;
  • To display the menu, click on right button mice;
  • We find the “screen resolution” section - Windows 7, and if WindowsXP is installed, then “graphic characteristics”;
  • then you need to select an acceptable option to duplicate the screen.

Any laptop has a specific F4 key, if you press it together with the Fm button (located to the right of Crtl) repeatedly, you can select the right option For external screen- this is how the computer begins to see TV.

Video card and drivers

Open the “Device Manager” of your laptop to check the driver versions installed video card. Outdated software is the main reason why the TV does not see the laptop. In this case, you need to go to the manufacturer’s website, where you can download new “firewood” - the video card will be updated, you will be able to establish the required connection.

Perhaps the fault is that operating system was infected with viruses or unauthorized penetration of malware occurred. Using a powerful antivirus program (computer protection program) capable of finding all spies of any level, carefully scan your computer and reconnect.

Some experts strongly advise checking the version for your Smart TV platform: sometimes a laptop does not connect using HDMI for this very reason. and perhaps the problem will go away.

Connection port problem

Any connector can have mechanical damage or get burned during a power surge, which in our electrical networks Not unusual. Experienced technicians advise connecting the HDMI cable when devices disconnected from the network, even antenna cable It is recommended to turn it off during this time.

There is also a very rare reason why the TV does not see HDMI: it simply does not have additional food on the video card, and without this the connection will not work.

All details and connection options can be viewed using this video:

Troubleshooting algorithm

If you know the reason why there is no image on the TV screen, then eliminating various violations is already a solvable task. This is what the approximate procedure for eliminating detected faults looks like:

  1. Check the quality of the connection, visually check the external condition of each connector or connecting cables if the laptop no longer sees the TV.
  2. Then the setup of the computer systems is checked: check what choices were made in the menu items responsible for connecting devices.
  3. Check for updated video card drivers.
  4. In some cases, it won’t hurt to check the settings of the video card itself once again.
  5. Retry smart scan entire computer to make sure no malware.
  6. Visually check the condition of the multimedia ports and their proper operation - positive result will be immediately visible when connected to another device, for example.

If you have done everything possible, but there is still no signal from the laptop to the TV, try other types of connection. Use a rule of thumb where all existing methods connections. The due diligence process will look like this:

  • first we determine the available connections and connectors that the household appliances we have chosen use;
  • disconnect the TV and laptop from the network;
  • connect the laptop to the TV using a proven HDMI cable;
  • turn on the TV, setting up its connection to the computer using the remote control;
  • we activate the laptop, if the signal passes, then a picture similar to loading the operating system should be displayed on the TV screen;
  • there is no signal - go to the “Device Manager” section, find out which ones are available active species connections;

  • if possible to install connection via VGA, then you need to connect a similar cable to the products;
  • then we carry out the same actions as with HDMI, only press the “VGA” button on the remote control;
  • if you decide to connect via DVI, then connect the cable to the appropriate connectors, and select a similar option in the TV settings.

If the technique never started working together, the reason lies in internal breakdown, which can only be diagnosed and fixed by a specialist. Of course, if you have knowledge in the field of electronic devices, you can try.
