The HDMI input on the computer does not work. There is no picture on TV when connected via HDMI

The HDMI standard makes it easy to display image and sound from a laptop or computer to an external monitor or TV. To transmit picture and sound, just connect the computer to the device via a cable. But, as with any other data transfer standard, problems can arise with HDMI, including due to incorrect Windows settings. One of the common errors that users have to face is the lack of sound on the TV when connecting a computer to it via HDMI. There are several ways to fix this problem, which will be discussed below.

Please note: Before proceeding with the tips below, make sure that the lack of sound on the TV when connecting a computer to it via HDMI is not due to the settings of the TV itself. Often the reason is quite banal - the TV sound is reduced to zero or the “Silence Mode” (Mute) is turned on.

Selecting the correct playback device

When connecting an external information output device - a TV or monitor - to a computer via HDMI, operating system Windows should automatically determine that audio will be streamed through the connected source by default. If this does not happen for one reason or another, the user needs to independently assign the TV as the audio playback device. For this:

Important: If on the list available devices playback, you do not see the connected monitor or TV, right-click in any empty space and check the “Show disconnected devices” and “Show disconnected devices” checkboxes. Try to find a connected monitor/TV among them.

In a situation where even among hidden devices it was not possible to detect a TV/monitor connected via HDMI, you can try the steps described below.

No sound via HDMI on TV due to hardware problems

The second most common reason for no sound when connecting a computer to an external monitor/TV via HDMI is a hardware problem. It can manifest itself in two cases:

Installing drivers for audio output via HDMI

Another reason why there is no sound via HDMI on the TV may be the lack of drivers. Most often, this problem occurs if, when installing video card drivers, the user manual mode I selected the components to be installed and disabled the installation of drivers for HDMI.

You can find out whether drivers are installed to output audio via HDMI to your computer in Device Manager. To do this you need:

If the list of available sound devices only includes a sound card, you need to download the drivers for the video card to your computer and install those components that are responsible for transmitting sound via HDMI. To do this, go to the Intel, NVIDIA or AMD website and download the latest video card drivers, then run their installation. At the installation stage, select manual mode and be sure to check “HD Audio Driver” among the available drivers.

Please note: The driver responsible for audio output via HDMI is called “HD Audio Driver” on the NVIDIA video card. On other maps it may be called differently.

After installation necessary drivers Restart your computer and try connecting it via HDMI to your TV again.

In the era of high development digital technologies we can get the best from TV and computer through their connected connection. Creating such a special connection between technical devices is possible with the assistance of DVI, HDMI or VGA connectors. But, often various reasons, these devices do not want to make contact with each other. You can always eliminate existing problems if you know what lies at the root of their occurrence. An approximate description of common problems will help you navigate difficult situation and will open up new ways to eliminate them.

What is HDMI?

HDMI is a multimedia interface that transmits video data high resolution and digital audio signals. This type of cable is widely used for connecting TVs, game consoles, stand-alone video players, as well as audio receivers to mobile devices And computer technology. If you want to play a video or show photos on a big screen, then you can’t do without such a device.

Manufacturers of modern multimedia equipment now add HDMI connectors to the standard equipment of devices by default. There are five main types of such ports, which are marked with Latin letters from A to D and differ in size. In addition, each type of HDMI cable differs from the other in functionality and scope of application.

It is also worth noting that in Lately The possibilities and advantages of a wireless connection when connected via HDMI adapters are widely discussed. Outwardly, they resemble USB-Bluetooth and differ only in the connectors.

Connecting the TV

Watching movies, amateur videos and photos is much more convenient on a big screen, especially since almost all modern video cards allow you to connect to a TV. The picture quality and sound playback on a computer is significantly different from what you will see and hear if you connect a blue screen to it.

There are the following basic ways to connect a TV to a monitor:

connection via the VGA interface, which is equipped with almost all modern video cards;
connection via HDMI cable (this method is widely used for transmitting high definition signals);
connection via the DVI interface, which is universal for digital and analog monitors (originally designed for digital monitors that did not require conversion of incoming signals).

The connection can be realized without using various types of wires. A connection via WIFI allows you to quickly establish contact between the monitor and the screen, and in addition, frees your home from a web of cables.

Turn on devices

A TV can always be transformed into a powerful multimedia platform if correct sequence turn on all devices.

The connection algorithm is as follows:

The sequence of operations must not be changed under any circumstances. After connecting the devices, they need to be configured.

How to set up your display

Operating windows systems 8 and 7 themselves detect the device and configure the connection if an HDMI cable is used. When using other connection methods, you need to know how to configure the image output to the display yourself.

The algorithm for displaying images on the display in windows 7 and 8 systems is as follows:

Setting up the display in the WindowsXP operating system is always done manually. You will have to press the buttons a little and switch the TV to AV mode.

Setting up the video card

After the connection is made correctly, a picture from the computer should appear on the TV screen. If the image does not appear, you need to adjust the inputs and outputs and adjust the resolution.

The video card is responsible for all visual effects and display of multimedia files on the computer. Each model has its own characteristics that should be taken into account when setting up.

But the general algorithm of actions will always remain unchanged:

Successful completion of the connection of two devices will be indicated by a system message about the use of an additional screen.

Outputting sound to TV

Playback of multimedia files will be complete only after setting up the sound card. If you don't do this, then you'll just end up in the silent film era.

Sound output to the TV is carried out via next plan:

If after making all the settings nothing plays, you need to pay attention to whether the video card even supports your sound output method.

What to do if the computer does not see the TV via HDMI?

Almost every modern TV model is equipped with an HDMI connector. Most video cards support multimedia output in this way. But if the computer does not see the HDMI TV, you need to find out what is preventing the two devices from connecting.

Diagnosing problems includes the following steps:

step one: check the HDMI cable for serviceability and correct connection;
step two: check the system settings and working with a computer via an HDMI cable in the TV menu;
step three: reinstall the video card drivers.

Some types of TVs simply do not support an HDMI connection and you should not forget about this. It's about(mostly) about outdated models that are not equipped with a special connector. In such cases, you can try other connection methods. For example, via DVI or VGA.

Video: computer does not see TV

Possible reasons

The disease can be cured if you know the causes of its occurrence. Problems connecting your TV to your computer can be resolved if you know what caused them.

The main reasons why the computer does not see the TV:

the connection cable is damaged, incorrectly connected or defective;
the computer does not detect the TV;
the TV does not support the selected connection method;
video card drivers or lack thereof;
damage to interface ports;
the computer has a removable video card installed;
burning of internal parts of a TV or computer.

There can be many reasons for problems in the coordinated operation of two devices. If you are not a specialist, then you can confidently diagnose only external problems associated with the cable.

Solving the problem

Knowing the causes of the main violations in the symbiosis of a computer and TV, any problem can be eliminated.

Troubleshooting algorithm:

You shouldn’t try to fix problems on your own that only a professional can handle. But basic mechanical restorations are within the competence of any PC user. Do you really need to contact a technician to correct the position of the cable?

No signal from computer to TV

The absence of a signal most often indicates that this model There is no way to connect a TV via HDMI. It is possible that the connection type is incorrectly marked in the options. In this case, you should try other connection methods.

Photo: connecting a TV to a video card

The reason for the lack of signal on the TV may be viruses, outdated drivers for the video card, or cable failure. Be sure to check the video card settings and select the correct type of information display. Finally, look into the BIOS and check the activity of the connection elements.

Checking the signal through different connections

Through trial and error you can achieve the truth. If after all your efforts you cannot resolve the connection problems, you can check the signal different ways connections.

The due diligence process is as follows:

If the work done does not make any changes to the existing state of affairs, then, most likely, the reason for the lack of signal is some kind of internal breakdown or flaw in the cables and I/O ports.

The development of digital and multimedia technologies has given us the opportunity to enjoy viewing photographs, amateur and professional videos on a large screen TV. It is for this purpose that televisions are connected to phones and computers. The connection between two pieces of equipment, if done correctly, is established in as soon as possible.

But it happens that the image or sound is not reproduced on the TV screen. There can be many reasons for this. It is important to install them so that the problem can be eradicated in the future. Only a specialist can conduct a detailed diagnosis of problems and fix them. You shouldn’t undertake serious restoration work yourself. But this rule does not apply to the elimination of minor and primitive defects.

The computer does not see the TV via HDMI: reasons and solutions

Today, almost any television panel can be connected to a personal computer or laptop. The equipment is connected via an HDMI connector. But often users encounter the problem that the computer does not see the TV through the HDMI input or there is no sound. There are several reasons why such problems occur, so it is necessary to identify the problem sequentially. Read also, which cable to choose to connect your TV.

Device connection methods

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

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

The HDMI connector on your TV is usually located on the back or side. The computer almost immediately after connecting begins to see the other device, but problems may arise that there is no image or other errors. Moreover, this is the most proven and common way to connect a laptop to a TV. Read also, ways to connect Xbox to TV.

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:

The cable is not connected correctly or is defective.
Monitor settings error.
Incorrect operation of the laptop or PC video card.
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

First of all, you need to check the quality of the wire connections and the condition of the connectors.
Next, you need to check that the computer settings are correct.
Then it checks for driver updates and video card settings.
Run an antivirus program to scan for malware.
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.

In any case, if there is no picture, first check whether the connectors are fully inserted into both devices. And are there any foreign objects on the adapter itself? You can also try installing a different cable to make sure this error does not occur. Read also why the TV does not connect to Wi-Fi.

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 the signal from the TV is going along the right path, 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:

Hover your mouse over any free space on the screen and click on the right button.
In the list that appears, select “Screen resolution” or “Graphics characteristics” depending on the type of OS.
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 the new drivers that are included in global network for each device model. Sometimes a complete reinstallation or replacement of an element may be necessary.

Read also how to adjust the sound on your TV via your computer.

The last thing that could be the reason that the TV does not receive an image via HDMI is a broken port. For diagnostics, check the functionality using other adapters. If the devices become visible, this is where the error lies.

Signal check

If all manipulations do not bring the desired result, it is recommended to check the signal using other connection options.

Check in progress in the following way:

Disconnect equipment from the network.
Connect the HDMI cable to the computer and screen.
Turn on the TV and press the “Source” button.
In the column that appears, select the HDMI operating mode and click “OK”.
Turn on the computer: when the OS boots, if everything is done, the TV screen and monitor will broadcast identical information.
If the signal does not appear, then you need to go to the “Device Manager” to see if there are still available connectors for connection.

7. For example, if VGA is available, then you need to perform the same algorithm of actions, only set the appropriate mode in the settings.

If even after these steps the equipment does not start working, then most likely the problem is an internal failure.

Thus, the computer may not see the TV via an HDMI cable for various reasons, which can be diagnosed and fixed at home without special knowledge in the field of modern technology. Read also how to make a TV from a computer monitor.

Why doesn't the computer see the TV when connected via hdmi?

Today, any user can connect a laptop or desktop computer to a flat-screen LCD TV using an HDMI cable, and then enjoy an enhanced image. 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 you just purchased the cable from a store where it was extensively tested. There are many reasons for cable malfunction, and searching the real problem must be done sequentially.

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 image quality and sound are checked, but the specific connectors and connection sockets on the TV are never checked - in best case scenario make sure of their availability, and even then not all buyers. It often happens that the cable itself does not 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

Press the button on the remote control to select the external input option. It depends on the specific model of the product 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 a detailed list of active inputs. Select and confirm by pressing OK or Enter exactly the desired input into which you previously connected the cable coming from the laptop.

Working with the monitor

If the laptop does not see the TV when several monitors are connected simultaneously, then additional settings need to be made. These simple manipulations can be performed by every user without special education:

move the cursor to any free space on the desktop;
To display the menu, click on the right mouse button;
we find the “screen resolution” section - windows 7, and if it’s windowsXP, then “graphics 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 desired option for the 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 of the installed video card. Obsolete 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 lies in the fact that the 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.

Connection port problem

Any connector may suffer mechanical damage or burn out during a power surge, which is not uncommon in our electrical networks. Experienced technicians advise connecting the HDMI cable when the devices are disconnected from the network; it is recommended to even disconnect the antenna cable at 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.

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:

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

Signal check

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 define available connections and the connectors that our chosen one uses Appliances;
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;
no signal - go to the “Device Manager” section, find out what active connection types are available;

if it is possible to establish a 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 make a connection 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 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.

The TV does not see the computer via HDMI

HDMI is a popular connection connector various equipment between themselves (for example, a computer and a TV). But when connecting, various kinds of difficulties may arise - technical and/or software. Some of them can be solved on your own; to eliminate others, you may need to send the equipment in for repair or replace a faulty cable.

If you have a cable with any intermediate adapters, for example, you can use it to connect to a DVI connector. Instead, it is better to try using a regular HDMI cable operating in HDMI-HDMI mode, since the TV/monitor may not accept a cable that implies the ability to connect to several ports simultaneously. If the replacement does not help, then you will have to look for and eliminate another cause.

Check the HDMI ports on your computer/laptop and TV. Pay attention to these defects:

Broken and/or rusted, oxidized contacts. If any are found, the port will have to be replaced completely, because contacts are its most important component;
Presence of dust or other debris inside. Dust and debris can distort the signal, which will cause inconvenience when playing video and audio content (low or no sound, distorted or slow images);
Review how well the port is installed. If it begins to loosen at the slightest physical impact, then it will have to be fixed either independently or with the help of specialized service workers.

Perform a similar check on the HDMI cable, paying attention to the following points:

You need to understand that not all cables fit all HDMI connectors. The latter are divided into several main types, each of which has its own wire.

Method 1: Correct TV settings

Some TV models are unable to independently determine the signal source, especially if some other device was previously connected to the TV via HDMI. In this case, you will have to enter all the settings again. The instructions for this case may vary slightly depending on the TV model, but its standard version looks something like this:

For some TVs, the instructions may look slightly different. In the 2nd point, instead of the suggested options, enter the TV menu (the button with the corresponding inscription or logo) and select the HDMI connection option. If the TV has several connectors of this type, then do the rest in accordance with points 3 and 4.

If this method does not help, use the instructions for the TV (it should tell you how to connect via an HDMI cable to this particular device) or pay attention to other ways to solve the problem.

Method 2: Setting up your computer

Incorrect configuration of a computer/laptop with multiple screens is also the reason why an HDMI connection is ineffective. If you do not have any external displays connected to your computer other than your TV, then this method can be ignored, since problems arise if another monitor or other device is connected to the PC or laptop using HDMI (sometimes other connectors, for example, VGA or DVI).

Step-by-step instruction According to the settings for working with multiple screens for devices on Windows 7/8/8.1/10 it looks like this:

It is worth remembering that HDMI is capable of providing a single-stream connection, that is, correct operation with only one screen, so it is recommended to disconnect the unnecessary device (in in this example monitor) or select the display mode “Display desktop 1:2”. To begin with, you can see how the image will be broadcast to 2 devices simultaneously. If you are satisfied with the quality of the broadcast, then there is no need to change anything.

Method 3: update the drivers for the video card

Initially, it is recommended to find out the characteristics of your video card, since some graphics adapters are not capable of supporting image output on two displays at once. You can find out this aspect by looking at the documentation for your video card/computer/laptop or by using third-party software.

First, update the drivers for your adapter. You can do it like this:

You can also download and install drivers from the Internet, always from the manufacturer’s official website. It is enough to indicate the adapter model there in the appropriate section, download the necessary software file and install it following the instructions.

Method 4: clean your computer from viruses

Most often, problems with signal output from a computer to a TV via HDMI arise due to viruses, but if none of the above helped you and all cables and ports are working properly, then the possibility of a virus penetration cannot be ruled out.

To protect yourself, it is recommended to download and install any free or paid antivirus package and regularly use it to check your PC for dangerous programs. Let's look at how to run a PC scan for viruses using Kaspersky antivirus (it's paid, but there is a demo period for 30 days):

Problems with connecting a computer via HDMI to a TV rarely arise, and if they do occur, they can always be solved. Provided that your ports and/or cables are broken, you will have to replace them, otherwise you won’t be able to output anything.

We are glad that we were able to help you solve the problem.

Why doesn't my TV see HDMI?

The topic of the conversation should rather have been called “How to connect a TV to a computer via HDMI.” Most of beginners do the procedure incorrectly, asking questions that are difficult for a professional to answer. Let us remind you: HDMI is a high-performance digital media content transmission interface. Images, music, other entertainment content. Will it be possible to listen to music on TV? It will be possible from a home theater, if you have one! The HDMI port was invented as a high-performance means of transmitting information. Let’s skip a few words, find out why the TV doesn’t see HDMI, and how to fix it.

Connecting a TV to a Computer HDMI

Correctly connecting the TV using HDMI

Home theater owners should know the truth - a digital media device has a playback source menu. The easiest way to illustrate the fact is with old music centers. Traditionally, devices had three blocks:

Cassette decks: recording, playback.
Radio broadcast reception.
Laser discs.

Moreover, the blocks refused to play melodies simultaneously. It was necessary to switch sections using a special lever. Even a modern telephone is often equipped with an FM button... Can you guess why the TV doesn’t see HDMI? Go ahead. The back of a TV typically contains half a dozen output jacks. Among the troops we will find a “tulip” formed by three petals, at times VGA puffs up, and certainly HDMI. Traditionally, the list is not limited to a meager list; see the instructions for more details. From the remote control, with the elusive press of a button (with only one HDMI port), you can select a source from the menu. The selection tool can be the Source key. You need to find a menu listing sources, select the cable connection port. There can be more than two HDMI connectors; it is important to track the correct number.

The computer usually avoids such tricks. There is no direct option to select the direction of signal transmission. However:

On laptops, the function keys Fn+F3 (F4) will open a pop-up system menu listing interesting options:

Computer only. The image will not be sent to the external monitor (TV). Most people choose the named option. Don't be surprised that the TV can't see the laptop.
Duplicate. The laptop screen will be duplicated by the TV. This is what most people need.
Expand. Some people like to drag player and browser windows onto the TV, making it more convenient to watch movies. Let's be afraid to judge (tastes are individual), select the Expand option, lengthening the desktop.
Projector only. The laptop screen turns off. The image will be displayed individually on the TV.

Desktop personal computers detect TV independently. Otherwise, take the trouble to visit the driver menu and select the required broadcast port.

It is easier to control a connected TV using the desktop context menu. First, right-click on the free space, select the Screen Resolution option. Successful TV detection makes the “Multiple Monitors” button available. You will see four options that are exactly the same as the laptop options. Read the values above. It happens that the computer does not see the TV via HDMI: it makes sense to look here and look at the context menu. The monitors will be numbered; you can swap ports by simply clicking and selecting the object for changing system parameters.

There is no “Multiple Monitors” button in case of inconsistency: the system does not see the TV. Both devices must be turned on (230 volt power supply).

We connect the TV and computer with a cable

Pros say: it is possible to hot-connect a TV and computer via HDMI. Avoid risking expensive equipment; perform procedures in the absence of power. The first thing you need to do is turn on the TV. In normal mode, devices see each other. Problems mean there is a breakdown. Is hot plugging possible or not?

Modern TVs can easily replace a computer display. But how does a computer connect to a TV?

We have collected various ways solutions to this common problem.

Connection selection

First, attention will be paid to the optimal options regarding image quality, with which you can easily make a connection. After this, several additional methods will be given.

There is a possibility that the user will need to buy a cable from the store. Usually it is not very expensive, and you can purchase various devices at a specialized radio store or a retail chain that sells consumer electronics.

Please note that the presence of gold plating on expensive cables does not in any way affect the quality of the displayed image.

So, here are a few options for how to connect your computer to your TV:

HDMI- an ideal option, because to work with it you just need to connect the connectors. As a result, not only sound, but also image will be transmitted well. Only possible the only problem– sound from a laptop may sometimes not work.
VGA- one of the easiest ways to connect television. To do this, you only need a cable, which is sold complete with monitors. There is a possibility that the user has an unused device at home. If necessary, you can buy it at a specialty store.
With cable from DVI the situation is the same - to work with it you only need to buy an adapter and cable.
Alternatively, you can use a composite cable S-Video. You can work with it either through a cable or through an adapter. It’s just that he’s not considered the best way connections because the image may not be very clear. So such a connection is not used if modern technology is available. The connection occurs in the same way as when working with household players.

Connecting using HDMI

Surely many users have heard about this connector. It is on all modern TVs.

The HDMI cable has the same connectors on both ends.

You can buy a cheap cable. But if the user plans to work in 3D mode, it is better to use the latest version of the HDMI cable.

A similar socket is located on the video card near the monitor connection.

If there is no discrete video card, the socket will be located on motherboard, that is, near the USB port. However, it will look similar.

With a laptop everything is much simpler - it has the same HDMI socket. But it’s located on different sides depending on the model the user is working with.

Sometimes the TV is hanging on the wall and it can be very difficult to insert the cables from the back. It is for this situation that a cable with plugs at right angles is sold.

Alternatively, buy a special HDMI corner.

Connecting a TV to a computer via a VGA connector

Video Graphics Array is an interface designed to receive and transmit analog video signals. There is no sound transmission in this option for connecting the TV to the computer.

Before connecting, make sure that both devices - the computer and the TV - are equipped with VGA connectors and have a special cable.

To make such a connection, your computer must be equipped with an operating system of at least Windows 7.

Connect the PC and TV with a VGA cable when turned off, then use the remote control remote control TV, press the SOURCE button (in some models this may be INPUT) and in the menu that appears on the screen, specify as an external signal VGA(in some models - PC or RGB).

After this, confirm the selected changes by clicking OK.

Right-click on an empty space on the desktop and in the drop-down list go to the screen resolution menu.

In this menu, you are given the choice of using both a TV and a computer monitor, as well as setting the required resolution.

Additionally, you can choose to use multiple screens, which gives you the following options:

Duplicate screens- a function that allows you to get the same image both on the monitor and on the TV screen;
Expand screens- will allow you to simultaneously watch a video on the TV screen and, for example, type text on a computer;
Show desktop 1 or 2- this function operates only one of the available screens - either a monitor or a TV.

In general, the process of such connection is not difficult, however, it creates some inconveniences associated with the transmission of sound in this embodiment.

It will have to be connected with a separate cable or use an external speaker system for these purposes.

S-Video

Another option for connecting a TV to a computer is to connect using S-Video connectors.

This option is convenient because all TVs and computer video cards (except very old ones) are equipped with an S-Video connector.

All you need to do is connect these devices with an “S-Video to S-Video” cable.

Before connecting, both the TV and the computer must be de-energized, after which you insert one end of the cable into the connector on the computer’s video card, which is a round black socket, and the other into the S-Video socket on the TV.

As the operating system loads on the computer, the TV screen will blink, indicating that an external signal source has been detected.

The next step is to configure the video card. To do this, click on an empty space on the desktop and in the menu “ Properties» go to the tab « Options» .

Then select the item « Additionally» and in the window that opens, opposite the name of the video card, activate the item « Clone» .

After applying this parameter, click on the item « Display" and select the name of the TV from the available list.

Then, on the TV, search for the signal source and adjust the image.

Miracast

Miracast technology differs from DLNA in that this option for outputting multimedia information from a TV to a PC simplifies the task of viewing not only recorded files stored on the gadget’s hard drive, but also played online on one of the built-in web browsers.

But Miracast technology has the only drawback - it is very demanding on computer resources.

So it is supported only by certain computers, as well as tablets and laptops that have powerful hardware.

It is important to implement such modern technologies on the TV itself.

If the TV only optionally supports Miracast, then you will have to spend extra money on an adapter that easily connects to the HDMI port.

The technology of a wireless monitor is very simple - the displayed image is compressed using a special algorithm.

After this, it is mirrored via Wi-Fi to a large TV display.

In this case, there is no need to connect the TV to one of the local networks using a router.

Thanks to the receivers, a separate mini-network is organized, simplifying communication with a PC.

To successfully transfer images, install the Wireless Display add-on on your computer and start broadcasting.

A PC and Smart TV can be connected without a special router.

As many probably know, home network can be created without using a router. IN in this case The laptop will serve as an access point.

This is done in several ways:

You can create a connection in one of the special management consoles;
Alternatively, use ;
Use third-party programs, for example, Virtual Router Plus.

Please note that distinguishing feature Most built-in Windows tools – greater reliability and stability.

In addition, users will no longer have to waste time searching for programs and installing them on their personal computer. So the registry won't be too clogged.

This method is considered one of the simplest.

Once logged in as an administrator, proceed to launch the command line. To cope with this Windows 8 task, use the key combination Win+X.

When the menu appears, you must select " Command line" In the seventh version of the operating system, you need to press the Windows + R key combination in the window that opens, and also write CMD and press Enter.

Be sure to write the following command netsh wlan set

and after that press Enter.

The creation of a new network will then be completed and you can begin to launch it. For this purpose, write on the command line

Hostednetwork

It is important to say what to create virtual network you can only do it once.

However, after the module is rebooted, the user must enter a command to successfully launch the Internet.

As a result, the user will only have to connect the TV to the computer by doing necessary actions, which have already been done when working with the router.

You can control TV from a PC via a wireless Wi-Fi network using the same programs.

There are various add-ons that make it much easier to control your TV using a smartphone.

In this case, the phone is used as a control panel.

So, this article provides the basic ways to connect a computer to a TV.

It is very easy to cope with this task if you choose the appropriate option and follow the instructions given. Then the user will not have any difficulties connecting.

In this article I would like to consider a common problem when There is no signal on the TV connected via HDMI cable.

No signal via HDMI

HDMI says no signal

If this is your first time connecting your TV to your computer and you see a floating message on the screen hdmi no signal, you need to make some settings both on the computer and on the TV itself.

No signal via HDMI to TV

In order for it to appear HDMI signal on TV, take the remote control and press the button with the image or name SOURCE.

After the connection options appear on the screen, select the appropriate HDMI port. If there is more than one such port, you will be offered multiple ports. Select the one you need and wait for the picture to appear.

Why is there no HDMI signal?

If after this the signal still does not appear on the TV, as indicated by the floating message, open the screen settings on the computer. To do this, click on Desktop right click and select Screen resolution .

In the window that opens, in the line Screen select your device e.g. Digital TV.

Computer news, reviews, computer problem solving, computer games, drivers and devices and other computer programs." title="programs, drivers, problems with the computer, games" target="_blank">Компьютерная помощь, драйверы, программы, игры!}

→ Duplicate these screens . In this case, the image from the computer monitor screen will be duplicated on the TV, that is, both the TV and the computer will show the picture.

→ Expand these screens . Don't choose.

→ . The image will be displayed on the device that is first in the list of screens.

→ . Accordingly, the image will be displayed on the device that is second in the list of screens.

HDMI signal lost

Why did the hdmi signal disappear on the TV?

One of the common problems is when the image was shown on the TV via hdmi and disappeared for no reason. What to do if on TV hdmi signal lost and why did this happen?

The solution to the problem is very simple. In most cases, for one reason or another, the screen display setting, which is still there in Screen Resolutions in the Multiple Screens line, is to blame.

Possibly selected Display desktop on only 1 or Display desktop only on 2. That's why The image is shown only on one of the devices. If you want to show on both devices, select Duplicate these screens.

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 will appear with a list of available inputs. 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, and 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, for 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 used to connect the TV is broken or damaged. This can happen both with a previously used cable and with a new one; do not forget about the likelihood of a manufacturing defect. The most simple solution will replace the connecting cable.
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 HDMI connection 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.
TV and computer long time worked fine, 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 an external device requires additional power, and the video card is not capable of operating 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 an 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:

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.
DVI. A more modern option. Can work with analog and digital devices. Has its own subclasses.
S-Video. In addition, you will have to purchase an adapter.
RCA or tulips. Connecting a laptop and TV using this method is rare.
Scart. A popular method, since such a connector is found in modern TV models.
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:

The cable is not connected correctly or is defective.
Monitor settings error.
Incorrect operation of the laptop or PC video card.
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

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

Cable check

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

Monitor settings

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

Video card error

To fix this, you need to try installing new drivers that are available on the global network for each device model. Sometimes a complete reinstallation or replacement of an element may be necessary.
