I noticed that very often there are questions that arise during setup DLNA servers on a computer to watch movies on a TV that supports DLNA.

Namely, questions about the problem when the TV does not see the DLNA server created on the computer. And accordingly, he does not see the files (films, photos, music) that are on the computer.

Reasons why it may appear similar problem, there can be a lot. But, most likely, this is due to the fact that the antivirus or firewall installed on your computer (possibly standard Windows firewall) , blocks the connection. They prevent your TV from seeing movies that are on your computer.

Here are the actual instructions for setting up DLNA:

If you did everything according to the instructions, but your computer still doesn’t see the TV, then first:

• Make sure that the server is running on your computer (laptop). The program you use should write about this.
• Check if your TV supports DLNA technology. This can be found in the specifications of your TV model. (just look at the manufacturer's website). If your TV has a Smart TV function, then it supports DLNA.
• Make sure that your TV and computer are connected to the same router. And that the Internet works on both (internet access is not required, but this indicates that the devices are indeed connected to the network).
• If, for example, it didn’t work out with the “Smart Share” program, then try “ Home media server(UPnP, DLNA, HTTP).”

If everything is fine with the above points, then you need to try disabling the antivirus. I know for sure that Avast likes to block such connections. But other antiviruses are no exception. You should also try disabling the firewall if it is installed on your computer. AND .

There is no need to completely remove your antivirus. Almost every antivirus has the ability to completely disable protection for a while.

As a rule, this can be done by right-clicking on the antivirus icon in the notification panel and selecting something like Pause protection.

This is how it's done in Kaspersky Internet Security:

Perhaps the antivirus will also ask you for how long to disable the protection, or ask you to confirm the disabling. Let me remind you what I showed using Kaspersky as an example. Internet Security. If you have a different antivirus, then things may be a little different.

After disabling the protection, go to the required menu on the TV (on LG, this is for example Smart Share) and see if your TV has seen the contents of your computer. You can also turn off and turn on the TV.

I'm sure everything will work out. If everything works and the TV displays folders or files that are on the laptop, then the problem really is with the antivirus.

Turning off the antivirus every time is also not an option. Therefore, you need to try adding your connection to the antivirus exceptions. Or, it may block the program itself, for example “Home Media Server (UPnP, DLNA, HTTP)”. In this case, the program must be added to the exceptions. Each antivirus does this differently. Look for something like: application control, application activity management, network activity, firewall.

As for the problems in themselves Wi-Fi routers, through which the devices are connected, then they have their own chips. In theory, there is no need to make any settings in the routers themselves. But, I saw advice in the comments that you can try unchecking the “Prohibit multicast” option on the tab where Wi-Fi settings are set.

Such a point, for example in Tp-Link routers, I haven't met. If your router settings have such an item, you can try it. Best wishes!

Today, any user can connect a laptop using an HDMI cable, as well as desktop computer to your LCD flat screen TV and then enjoy the enhanced picture. This connection is not always successful: for example, there may be no sound. But there are times when the computer does not see a TV connected via HDMI at all, although the cable was just purchased at the store. Reasons incorrect operation there is a lot of cable, and the search for the true problem must be done consistently.

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.

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

, it is recommended to even disconnect the antenna cable during this time.

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

Image output settings in Windows If the connection cord and interfaces work, but the system unit still does not display a picture on the TV screen, then the problem lies in the operating system settings. How to properly configure the system for different versions

OS, described below.

1. Windows 7.
2. On the desktop, you need to open the task menu and find the “screen resolution” item.

Select “connect to a projector” and click duplicate so that the image remains on each monitor. If you need to completely transfer the picture to TV, then click on “projector only”.

1. Windows 8.
2. After logging into the control panel, select the “Design and Personalization” submenu.

In the “display” section we find “multiple displays” and select “duplicate” or “extend the table to only the second display”.

1. In the screen options, select “display” and scroll down to “multiple displays”.
2. If all connections are made correctly, the second screen will be immediately displayed, all that remains is to indicate exactly how to use it - duplicating it or as the main one.

Setting resolution and frequency

Sometimes, after following the recommendations listed above, the picture still does not appear. In this case, the reason may be that the TV and the system unit are not compatible in their parameters. For example, for an old SD or HD TV, the FHD resolution set on the PC video card is too high. In this case, you should go into the screen settings using the above algorithms and, selecting the second display (TV), lower the resolution for it.

The second reason that may affect the image is frequency. By default, the PC video card is set to 60 Hz. For TV it is worth trying to gradually reduce the value.

Important to remember! Some TV manufacturers provide connection to a PC, and there is a special mode for this. It can be combined with the image adjustment or separated. Through it you can select the appropriate resolution for your PC.

Some Samsung TVs I encountered a problem where a window with the text “HDMI mode is not supported” appeared. There were many recommendations on the forums to combat this, but it turned out that this is a problem with the factory firmware, and to eliminate the defect, you need to contact service center manufacturer where new software is installed. Modern Samsung TVs do not have such nuances.

How to update software on a video card

If connection difficulties continue after the recommendations above, updating the PC software associated with image output may help. The driver may be out of date, damaged, or simply missing. In such a situation, you should open the device manager and look at the “video adapters” tab. To do this, you need to select “manage” from the “my computer” icon in the menu, which opens by right-clicking on the mouse.

If near the adapter red or yellow icon is on, that is, there is a problem in the operation of this node. To update, you can immediately open its properties and select automatic update driver, but it is more efficient to download it from the manufacturer’s website.

Advice! The update can be found using the utility DriverPack Solution. Its convenience is that it scans the system itself and looks for all the necessary drivers.

How to adjust the sound

When connecting a TV to a PC, it may happen that there is an image but no sound. This means that the wrong adapters/cables were used, or the computer is not configured correctly.

1. In the tray, you need to click on the sound settings icon and select “playback devices” for Windows 7 and 8 or open “sound settings” for version 10 of the OS.
2. We see a list of available speakers, among them there should be a TV - switch to it and, if necessary, click “use as default”.

If the sound still does not appear, then you should check the volume on both devices and also update software sound card.

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. Update the Smart TV firmware and the problem may go away. If the technique never started working together

, the reason lies in an internal breakdown, which only a specialist can diagnose and fix. Of course, if you have knowledge of the electronic components of devices, you can try to repair the TV yourself. A pressing problem for many users today is image expansion with personal computer

to the home plasma display. “We connect the TV to the computer via HDMI, but there is no image,” - this is exactly how negative sounds come from the mouths of computer equipment owners. In this article, the reader will become acquainted not only with the method of connecting an additional display to a PC or laptop, but will also learn about correct settings

equipment. He will also be interested in recommendations from experts in the field of IT technologies.

About the goals pursued The larger the diagonal of the LCD screen, the more comfortable it is to view multimedia and the better the image detail in games and software. A film on a TV from a computer will allow you to see the smallest details, and a fan of a dynamic toy will feel the reality of the events taking place on the plasma screen. In fact, there are many advantages of using such a symbiosis, and they all relate to comfortable work

In recent years, many users have become interested in Internet television. Why pay money to the provider if you can watch your favorite channels for free from the official website of the television company? Therefore, the question is: “How to connect a computer to a TV?” sounds more and more often in the media. But so far things are going badly with ready-made solutions.

Computer hardware capabilities

It’s better to start with the technical capabilities of a personal computer or laptop. The fact is that it is not enough to buy an HDMI cable for your computer. It will be possible to connect to the TV only if there is an appropriate digital video output on the PC. Therefore, the user must become familiar with all outputs system unit and find the required port. It can be located on the video card or on motherboard at the computer and at one of the ends of the mobile laptop.

There are devices that do not have an HDMI connector. It is quite possible to find a VGA (D-Sub) or video output on old digital ports DVI with DisplayPort. Here everything depends to a large extent on the TV, which should have similar inputs. Having selected the right cable for your TV, you will always find the opportunity to output an image from your computer.

TV availability

But modern liquid crystal devices with HDMI ports have no problems - all manufacturers provide their equipment with a popular interface. Often they are not limited to one port at the factory and provide the user with the opportunity to connect several sources to output images via HDMI.

Larger LCD displays have a slightly different problem. We are talking about the resolution of the reproduced image and the frame rate. Before connecting a computer and TV via HDMI, the user needs to familiarize himself with technical characteristics both devices, compare their video signal transmission capabilities and find a parameter that will be supported by both plasma and PC. Often, all equipment manufacturers strive to ensure that equipment supports FullHD resolution (1920x1080) at a frequency of 60 Hz. True, there are exceptions that create problems for users.

Operation of devices of different generations

In situations involving connecting two devices with different interfaces(HDMI, VGA), users are often surprised why the computer does not see the TV via HDMI. The explanation is simple - it is impossible to connect equipment of different generations by combining analog and digital signals with one cable. In such situations, no adapter will solve the problem - you need a converter that can decode the signal at the hardware level.

Fortunately, they are present at foreign auctions ready-made solutions, which are able to solve all the problems of users with video signal transmission between devices of different generations. The cost of one converter is in the range of 20-30 USD. That is, which attracts a potential buyer. All the necessary cables for video transmission are always included with the converter, so the algorithm for solving the problem is simple: buy a converter and connect the TV to the computer via HDMI.

When the required interface is not available

Not all computers and TVs have an HDMI port - that's a fact. But you shouldn’t get upset ahead of time, since with obsolete devices the problem can always be solved. The fact is that old equipment is focused on transmitting an analog signal. Let by image quality this technology and lags behind, however, it has an order of magnitude fewer problems with the compatibility of different standards. Combining S-Vidio, VGA or RCA interfaces is much easier than converting to digital.

The user just needs to buy a cable for the TV and connect both devices. There are also many inconveniences that users will have to face. Firstly, audio cannot be transmitted over an interface cable. Accordingly, you need to buy another cable. Secondly, during operation, the sound card of a computer or laptop will not be able to create an individual audio stream for the TV. Accordingly, you can forget about the convenience of sharing a computer and TV.

The right approach to buying a cable

Problems may also arise for the user when choosing the wrong HDMI cable. The fact is that a digital video signal is not capable of being transmitted over long distances via cable without loss of quality. Therefore, the future owner needs to decide on the length before buying an HDMI cable for a computer to a TV.

The main thing is to always remember that the longer the quality cable, the higher its cost. It is necessary to measure the distance between the PC and the liquid crystal display (of course, not in line of sight, but taking into account the installation) and find a cable of the appropriate length on the market. Yes, it is customary for buyers to purchase wires with a reserve, but it should be small, since often the excess is rarely in demand - more often they just collect dust behind the TV or behind the computer. The main thing here is to find a middle ground in terms of the “cost - cable length” ratio.

Real offers from manufacturers

It is not easy to choose a cable for a TV of the HDMI-HDMI form factor on the market. Any buyer can verify this for himself; just look at the prices and assortment. It is logical to assume that expensive accessories have a high price only because they are made by serious brands. There is truth in this, but as practice shows, the more expensive the HDMI cable, the less likely it is that long distance The video signal will deteriorate. In fact, you have to pay for quality. Chinese consumer goods have no place in the domestic market.

IT experts recommend paying attention to the brand name (for example, Prolink, Cablexpert, Viewcon, Belkin), as well as focusing on the quality of the winding and the presence of ferrite filters near the connectors (barrels near the contacts). If an HDMI cable is required, the length of which exceeds 30 meters, then the user cannot do without a signal amplifier. The device is expensive, but copes with the assigned tasks 100%.

Physical connection of two devices

This article is not about the potential difference from school course physics, but the user still needs to know that there is a small amount of light on the video ports when the equipment is plugged into the mains. electric charge. Naturally, when connecting two devices, equipment with a large charge will transfer energy through the cable to the port of the connected device. Often the TV turns out to be more powerful, which, when connected, burns the output on the computer’s video card. Therefore, before connecting your computer to the TV via HDMI, you need to turn off the power to one of the devices (unplug the plug from the socket). Naturally, this problem bypasses all users who have grounding in their house.

Another problem that the buyer may encounter is the lack of a video signal when connecting the cable or the image transmission with noise. There is no need to touch the settings of your TV or computer - 99% of the time the problem is a low-quality cable. It needs to be replaced. In general, experts recommend checking the HDMI cable directly in the store to avoid connection problems.

TV settings

It will not be difficult for the owner of the liquid crystal display to press the “Source” button on the device’s remote control and select the desired signal source. All ports on the TV panel are registered and numbered, so all that remains is to combine the software part with the hardware part. Don't expect the PC image to appear on the screen right away. The main thing here is to get the display ready to receive a video signal. This will complete the setup of connecting the TV to the computer via HDMI. All that remains is to configure the video output of your PC or laptop.

Many users are owners of home theaters and other video and audio equipment that is connected to an LCD TV. Naturally, a situation may arise when all HDMI ports are busy. Many users are unlikely to want to physically rearrange the HDMI cable when working with a computer, so another solution is proposed. The video signal from the laptop can be transmitted to a tuner or receiver. In fact, there is no difference, since manufacturers use a single standard for transmitting images via HDMI.

Modern platforms

When it comes to the Windows 10 or MacOS operating systems, there are practically no configuration issues. The user only needs to restart the computer for the device to detect and connect the new display. The more modern the technology, the more efficient it is automatic setting- often via HDMI the signal is transmitted from the computer to the TV in FullHD format with a frequency of 60-65 Hz.

But there are exceptions, and they are primarily related to the video device driver. Therefore, there is no need to try to get the TV to work correctly from the remote control. remote control, only this will help fine tuning video cards. The main thing is to always remember that you need to change the parameters not global, but just one port, otherwise, through negligence, you can destroy the signal to the PC monitor, which will be very difficult to restore.

Working with drivers

Making a TV work like a computer monitor via HDMI, although difficult, is quite possible. There are many ways to do this, which the reader will get to know. Operating room owners Windows systems versions 7,8 and 10, you need to go to the control panel and select “Screen”.

By going to the “Setting Screen Settings” tab, the user will find that operating system I have already identified the connected TV, but the image is not being transmitted to it yet. The Multiple Displays option allows you to connect your TV as additional monitor to the computer. The list contains several options from which the user is asked to make a choice:

1. Duplicate these screens. The contents of the computer desktop will be displayed on the TV screen, and all actions performed by the user will be visible on both displays.
2. Expand these screens. The most interesting setting that allows you to virtually increase the desktop area (both vertically and horizontally).
3. Show on screen no. Manually assigning a port for video output is not popular among users.

Driver configuration features

It's easy to send a signal to a TV, but adjusting the picture quality and transferring sound from a computer to a TV is not so easy. First, you need to decide on the extension of the desktop - diagonally or vertically. Experts recommend focusing on the physical location of the TV in the room relative to the PC monitor. On the control panel, in the “Screen Resolution” menu, you need to use the mouse to place icon No. 2 relative to icon No. 1 so that it is convenient to move desktop objects between displays.

The second step is to adjust the TV screen resolution. The main thing here is to select a parameter that is supported by the connected display, otherwise a failure will occur and the video output port will be disabled. By clicking the "Advanced Settings" button, the user can select the display refresh rate, however, IT experts do not recommend changing the frequency unless the video card and TV support the 4K (144 Hz) standard. After making all the settings, you need to save the changes and exit the control panel.

Tricks with sound transmission

All users know that an HDMI cable transmits not only high-quality images, but also sound, but there is no corresponding setting in the display resolution settings. With audio transmission, everything is simple - at the hardware level, the sound is sent to additional screen along with the video. That is, the user just needs to move the video player window onto the TV display with the mouse. The sound will be muted in the computer speakers, but the sound will be activated in the TV speakers.

It is worth noting that mobile device or a computer is capable at the hardware level of supporting several video devices connected via HDMI, transmitting different images to them and providing them with sound. True, there are exceptions, and they depend on the video adapter and sound card. Low-performance devices sometimes malfunction; they simply do not have enough power to process digital video signals and high-quality audio.

Alternative driver setup

Not only using Windows You can configure the video to be transmitted to the TV screen. Owners are given the opportunity to ensure high-quality transmission using a video adapter driver (Nvidia or Radeon). The setup algorithm is still the same: we connect the TV to the computer via HDMI and set the HDMI signal source from the remote control.

But then the proprietary software of the video card manufacturer is used. By going to the application control panel Nvidia GeForce Experience or AMD Catalyst Control Center, you need to find the “Display” tab. One of the sub-items of this menu is responsible for setting up multiple displays.

Feedback from users

Often, when connecting a TV to a computer or laptop, device owners encounter problems that they try to solve together in the media. Most of the negativity that is found in reviews is associated with low-quality HDMI cables that were purchased at foreign auctions or in stores at a low price. A greedy person pays twice - all users who decide to save on buying an HDMI cable need to know about this.

After adjusting display settings and saving, did the image on the main monitor disappear? This is the second problem that users often have to face. The reason is quite simple - the parameters of the main monitor have undergone changes. There is only one recommendation here - when connecting a TV to a computer, you need to control your actions. Number 1 in the system is always the main monitor - its settings cannot be changed. You can do whatever you want with the remaining numbers (2,3,4).

Finally

Yes, in order to create convenience for yourself, the user needs a little time and investment. You simply cannot do without this. There are instructions that spell out all the steps, they need to be followed clearly:

• buy an HDMI cable;
• configure the video adapter driver;
• enjoy watching.

The algorithm is simple, but there is a lot of work to be done. In fact, there is nothing complicated, the main thing is to follow the recommendations of experts and carry out strictly specified actions. Only after receiving an image from a computer or laptop on the TV screen and making sure that there is sound transmission, can you enter Extra options and make fine tuning.

Details Questions and answers

Many users are perplexed: why the TV does not see the HDMI connection if the cable is new, the signal source is working, and the devices were switched according to the instructions. There may be several reasons for this state of affairs, so the problem should be searched for sequentially. We assume in advance that you are using an HDMI-HDMI cable without any intermediate adapters.

1. Check that the HDMI cable is working properly. Even very expensive brands are not immune from such a thing as manufacturing defects. In addition, due to careless use, the cable may be damaged. You can check the HDMI cable by replacing it with a guaranteed working analogue or by connecting it to other devices.

2. Check if you have selected the correct input source in the TV menu. To do this, press the external input selection button on your TV's remote control. Depending on the TV model, this may be a Source button, Input button, or just HDMI. When you click on it, a menu with a list will appear. Select and confirm by pressing the Enter (OK) button the input into which you connected the HDMI cable.

3. Check whether the mode for working with an external monitor (in this case, a TV) is selected on your computer. If your TV is the only monitor connected to your computer, it should be detected automatically. In other cases, for example, a TV and a display are connected at the same time, additional settings must be made.

On the desktop, you will need to right-click on a free field of the desktop, then go to the “Screen Resolution” (for Win7) or “Graphics Characteristics” (WinXP) menu and select the screen duplication option. For laptops, there is a special function button at the top of the keyboard with an image of the monitor icon (usually F4). By pressing it several times simultaneously with the Fn button (for example, Fn + F4), we select the appropriate option for using the external TV screen.

4. Make sure that the latest versions of drivers for your video card are installed on your computer. In the computer's Device Manager, determine the version of the video card driver you are using. On the official website of the video card manufacturer, find the latest versions of drivers and, if necessary, download and install them on your computer. Sometimes problems with an HDMI connection occur due to using an outdated version of the Smart TV operating platform.

5. Check your computer's operating system to see if it is infected with viruses or malware. You should scan your computer with any effective antivirus program with the latest signatures.

6. Check the HDMI ports on your TV and external source signal. Connectors may burn out or become mechanically damaged due to repeated cable misuse.

Although the HDMI standard allows for “hot plugging” of the cable, experienced specialists recommend that at the time of switching not only turn off both devices from the sockets, but also disconnect the antenna cable from the TV socket.

Another rather exotic reason why the TV cannot see the computer via an HDMI connection is the lack of additional power on the discrete video card used in it, but working with an external device requires increased energy costs. In the modern world of high digital technologies, there is often a need to connect a TV to a computer using VGA or HDMI connectors, but often various reasons

• these devices do not want to see each other and, accordingly, do not work. Let's look at the most common causes of such problems:
• The cable is definitely working, but the TV does not work with the computer, and the computer does not detect the TV. It is possible that the option to work with a computer via VGA or is not configured in the TV menu. The computer may have problems with the video card drivers; when the drivers are missing or unstable, the operating system may not respond to external video devices. There may be viruses on your computer, some of which block various methods of connecting external devices.
• A TV connected to a computer gives some signs that it is connected to a device, the computer also reacts in a similar way, but the devices still do not work together. The reason may again be video card drivers or their absence. In this case, you should check for the latest drivers for your video card. Also, the computer may not be configured to work with an external monitor. This function can be enabled in the settings of your video card.
• The TV and computer worked fine for a long time, but at some point they stopped cooperating adequately. In this case, there may be different options for operation, for example, both the computer and the TV are detected, but do not work; only one of the devices detects the other; neither device detects the other. There are several reasons for this situation:
  • broken connecting cable;
  • damage to interface ports on a computer or TV;
  • burning of internal parts of a computer or TV (capacitors, diodes, bridges, etc.), with such a breakdown, the image transmission function may partially work, that is, the devices see each other, but do not work effectively. The real reason is a lack of power or loss of part of the engineering circuit.
• Everything is working: TV, computer and connecting cord, but there is still no picture. It is possible that the computer has a removable video card installed, which requires additional power, which for some reason was not connected when the computer was assembled. It becomes clear that working with external device requires additional power, and the video card is not able to function at full capacity.

An approximate description of common problems will allow you to navigate the current situation and try various options for eliminating it. However, if you are not a big expert in electronics, it is recommended to limit yourself to testing the HDMI or VGA connecting cable. If this operation does not help, it is best to call professional TV technicians from the TV Service Center company, who can quickly determine any cause of the malfunction (from viruses on the computer to thin soldering of microcircuits) and fix it right at your home.

Connecting a computer or laptop to TV can occur in different ways:

1. VGA or D-Sud cable. Almost all monitors, PCs and TVs have this connector. This is an analog connection, which does not best convey all the nuances of video files.
2. DVI. A more modern option. Can work with analog and digital devices. Has its own subclasses.
3. S-Video. In addition, you will have to purchase an adapter.
4. RCA or tulips. Connecting a laptop and TV using this method is rare.
5. Scart. A popular method, since such a connector is found in modern TV models.
6. HDMI cable. A good option for connecting a computer.

Common Causes of Connection Failure

If the TV does not see the laptop, but the connection is complete, then the reasons may be the following:

1. The cable is not connected correctly or is defective.
2. Monitor settings error.
3. Incorrect operation of the laptop or PC video card.
4. The settings on the TV itself or any other brand are not configured.

Let's look in more detail at why the TV does not see HDMI and the second device through it.

Equipment testing steps

1. First of all, you need to check the quality of the wire connections and the condition of the connectors.
2. Next, you need to check that the computer settings are correct.
3. Then it checks for driver updates and video card settings.
4. Run an antivirus program to scan for malware.
5. Checking the port. It is recommended to connect to another device.

Cable check

If the TV connected to the PC suddenly stops working, and until that moment everything was set up properly, it means that the cable has come loose or has been broken. The first option is more common, since you can hook the adapter simply by passing by. But the second one is less common, since the optimal length of the HDMI cable is not so long as to lie on the floor and get under someone’s heavy foot.

TV settings

When the TV does not see the laptop via HDMI immediately after connecting the equipment, most likely it is incorrect to select the signal source on the TV itself.

If there is no signal from the computer, then on the TV remote you should find the “input”, “source” or “Imput” button; it may be written “HDMI” right away on the LG TV. Go to the window that opens and there, in the list of active inputs, select the one you need. Confirm the action by clicking on “OK”.

If the equipment still does not connect after the operations performed, we carry out further diagnostics.

Monitor settings

Having made sure that we are on the right path from the TV, we move on to diagnosing the laptop or PC screen, or rather, to the settings. They can be carried out by any user with basic knowledge of their computer:

1. Hover your mouse over any free space on the screen and click on the right button.
2. In the list that appears, select “Screen resolution” or “Graphics characteristics” depending on the type of OS.
3. Select the appropriate option for displaying the picture on TV. The device passport specifies the acceptable resolution, stick to it.

It's easier to do everything on a laptop. Press and hold the “Fm” and F4 buttons simultaneously until the optimal option is selected. After this, the laptop will connect to the TV correctly and the error that there is no image will go away.

Video card error

Another reason why the connection of devices does not work is the incorrect functioning of the PC video card. In this case, the laptop does not see the other device or does not display an image on it.

To fix this, you need to try installing new drivers that are available on the global network for each device model. Sometimes it may be necessary
