When the computer is connected to the TV, the image is disappeared. Conjugation problems: why the TV does not see the HDMI connection. Types of connectors that can have a video card

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

  1. VGA or D-SUD cable. There are almost all monitors, PCs and TV. This is an analog connection that will not give all the nuances of video files.
  2. DVI. More modern option. Can work with analog and digital devices. Has its own subclasses.
  3. S-Video. In addition to him, you will have to purchase an adapter.
  4. RCA or tulips. The connection of the laptop and the TV with this method is rarely found.
  5. SCART. A popular way, since such a connector is in modern TV models.
  6. HDMI cable. A good option for connecting a computer.

Common Causes Connection Fault

If the TV does not see the laptop, and the connection is made, the reasons may be the following:

  1. The cable is incorrectly connected or it is faulty.
  2. Monitor settings error.
  3. Incorrect work of a laptop video card or PC.
  4. No parameters are configured on the TV itself or any other brand.

We will analyze in more detail why the TV does not see HDMI and the second device through it.

Stages of equipment checking

  1. First you need to check the quality of the wire connection and the status of the connectors.
  2. Next you need to check the correctness of computer settings.
  3. Then the driver update and the video card settings is checked.
  4. Running antivirus program For scanning malware.
  5. Port check. It is recommended to connect to another device.

Checking the cable

If a TV connected to a PC stopped working, and before that moment everything was configured correctly, it means that the cable was departed or confused. The first option is more common, as you can hook an adapter, just passing by. But the second less often, since the optimal length of the HDMI cable is not so big to lie on the floor and get under someone's heavy leg.

TV settings

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

If there is no signal from the computer, then on the TV panel, you should find the "Login" button, "Source" or "Imput", may be immediately on TV from LG written "HDMI". Come in the open window and there, in the list of active inputs, choose the desired one. Confirm the action by clicking on "OK".

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

Monitor settings

Making sure that the signal comes from the TV along the right path, go to the diagnostics of the laptop screen or PC, or rather, to the settings. You can spend any user with the basic knowledge of your computer:

  1. Harvest on any free screen space and click on the right button.
  2. In the list that appears, select "Screen Resolution" or "Graphic Specifications" depending on the type of OS.
  3. Select the appropriate option to display a picture on TV. In the passport of devices, a permissible permission is written, stick to it.

On the laptop to do everything easier. Clamping the "FM" and F4 button at the same time, keep until you select optimal option. After that, the laptop to the TV will be connected correctly and the error that no image will go away.

Video card error

Another reason why the device connection does not work - the incorrect functioning of the PC video card. In this case, the laptop does not see another device or displays the image.

To eliminate you need to try to put new drivers that are in global Network For each device model. Sometimes it may be necessary full reinstall or replacement element.

The reasons why, when connecting a computer via the HDMI interface, there is no image on the TV, there may be a set. We will try to consider the most common of them.

Setting the entrance of the TV

First of all, go to the TV menu and check whether the HDMI port is selected as a source of the input signal to which the cable was connected. On the back or side panel of the TV there may be several ports, and each of them has its own index (HDMI 1, HDMI 2, HDMI 3 and so on). Therefore, you follow the television remote control to find and click the selection button. external source Signal. This may be the Source button (Source), Input (Login) or HDMI (each manufacturer has its own designation).

In the input list that opens, select the one to which you connected the HDMI cable connecting the TV with a computer. After selection the desired entrance Confirm the action by pressing the OK button. Now it should appear on the TV screen mirror reflection Computer desktop. If the screen continues to remain black, then the problem should be sought in the computer video card settings.

Configuring computer video card

It is possible that in the video card settings it is not indicated that the TV will be used as an additional monitor, so the image is fed to the computer monitor.

To troubleshoot the problem, right-click on the free field of the computer desktop. In the drop-down list, find the "Screen Resolution" (for Win7) or "Graphic Specifications" (for WinXP). A special menu will open in which you can choose the options for using the main and additional monitors. It is convenient to choose the cloning option (duplication) of the TV screens and computer Monitor. After pressing the confirmation button ok, an image should appear on the TV screen.

When the laptop is connected to the TV, the screen selection procedure looks much simpler: it is necessary to press the two FN + F4 function buttons several times on the keyboard until the option will appear. Instead of F4, another button can be used on which a pictogram with one or two monitors should be applied.

Mechanical breakdown

Well, the last reason explaining why when connected via the HDMI interface, there is no image on the TV, is a malfunction of the cable itself or the same communication ports on one or both devices.

No one is insured against the factory marriage, so in the event of a connection problem, it is necessary to check the health of the HDMI cable. The easiest way is to check the cable with its replacement to a guaranteed serviceable analogue or try to connect it to other devices.

Often, the reason for the failure of HDMI ports is incorrect connection of cable connectors. In addition to mechanical damage internal contactsThe port can burn due to static electricity problems. Although the HDMI standard supports the "hot connection" of the equipment, but due to the lack of in most of our household appliances Normal grounding of the HDMI ports continue to burn. Therefore, experienced masters advise before connecting the HDMI cable to completely de-energize the equipment, and an antenna plug is additionally removed from the TV.

The conversation theme was more likely to be called "how to connect a TV to a computer via HDMI". Most of the newcomers make the procedure incorrectly, asking for the issues that it is hard to answer a professional. Recall: HDMI is recognized as a high-performance digital media control interface. Images, music, other entertainment content. It will be possible to listen to music from the TV, home theater. HDMI port invented high-performance information transfer tool. We find out why the TV does not see HDMI, how to fix it.

Connecting a TV to a computer HDMI

Correct TV correctly using HDMI

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

  1. Cassette decks: recording, reproducing.
  2. Radio reception broadcasting.
  3. Laser disks.

Moreover, the blocks refused to reproduce the melodies at the same time. It was necessary to switch the sections with a special lever. Even the modern phone is often equipped with the FM button ... they did not guessed why the TV does not see HDMI? Go ahead. Rear panel TV usually contains half a dozen output connectors. Early the troops of the "tulip", formed by three petals, at times, the VGA will be filmed, without fail - HDMI. The poor list is traditionally the list is not limited, see the instructions in more detail. With a remote control by pressing a button (with a single HDMI port), you can select a source. The session can be the Source key. You need to find a menu, listed sources, select the cable connection port. HDMI connectors Maybe more than two, it is important - track correctly number.

The computer usually avoids such tricks. There is no direct option for selecting the direction of signal transmission. But:

  • In laptops, FN + F3 function keys (F4) will allow to reveal the pop-up system menulisted curious options:
  1. Only a computer. The image to the external monitor (TV) will not flow. Most people choose the named option. Do not be surprised that the TV does not see the laptop.
  2. Duplicate. The laptop screen will be duplicated by a TV. This is necessary for most people.
  3. Expand Some love to drag to the TV window players, browsers, watch movies more convenient. You will be judged (tastes individual), select the option to extend, extending the desktop.
  4. Only projector. The laptop screen is turned off. The image will be displayed individually on the TV.
  • Desktop personal computers TVs are determined independently. Otherwise, bother to visit the driver menu, select the desired broadcasting port.

Manage the connected TV is easier through the context menu of the desktop. First, right-click the free space, select the Screen Resolution option. The successful definition of the TV makes the "Several Monitors" button available. See four options that repeat 100% similar options of the laptop. Values \u200b\u200bRead above. It happens, the computer does not see the TV on HDMI: it makes sense to look here, to inspect the context menu. Monitors will be numbered by numbers, you can change the ports, just click, choosing the object of changing system parameters.

The "Multiple Monitors" buttons are not available in the case of nonsense: the TV does not see the system. Both instruments must be included (power supply network 230 volts).

Connect the cable TV and computer

Profi say: It is possible to hotly connect the TV and a computer via HDMI. Avoid risking expensive equipment, make procedures in the absence of nutrition. First you need to turn on the TV. In normal mode, the device see each other. Maltages mean the presence of breakage. Is it possible or not there is a hot connection?

Here is a Wikipedia page http://en.wikipedia.org/wiki/hdmi, in the characteristics of the standard HOT Pluggable phrase is present: YES. Transferring to Russian, we see connector docking with power on. Want to rebuild? Russia is a place where dealers, manufacturers fulfill the prescriptions selectively. Sorry the equipment - Reconfirm.

How close to start connecting the cable? No difference.

Sound. Connecting a TV to a computer HDMI

The HDMI interface from the very moment of creation by the Committee (2002) was conceived by a combined image transmission solution, sound. Available audio formats see individually (Wikipedia page), we note only, in Windows you need to select the sound source. Now the TV is considered by the system device, so this responsibilities can be assigned to it. To do this, it is easier to click the right lower corner of the desktop (speaker icon) of the right mouse button, select the playback device in the context menu. If there is no icon in the lower right corner, you need to press the arrow to the right of the designation of the Language RU (EN), to the left of the clock. There is a symbol.

After clicking, the window opens: playback devices will be listed. It will be necessary to disable everything except the TV, and the TV, on the contrary, to use. In 90% of cases, the native dynamics of the plasma panel will sound after a couple of seconds. Want to sound around? Similar acoustic system Going with a home cinema. Polyista Description of the device. A number of ways are offered to transfer sound from a TV to a home theater, anyone will suit, given the condition for the need to purchase the desired cable. Similar to the Source Control Panel with the Source Control Panel, select the desired sound source.

On the part of the TV, the procedure is more often transparent, and the eigenvens of the device are disconnected. Then drop anxiety if the movie support is recorded in mono mode. Each self-respecting home theater has inside splitter, easily breaking the sound on the channels of the format sound around.

Question-Answer: Connecting a TV to a computer HDMI

  • TV does not see HDMI cable. What to do?

We risk assumed: the wrong source of the TV is incorrectly specified. Check the faithfulness of the target (target) of the computer signal. Use the control panel for the TV. Through the Source menu or keys, or the HDMI will achieve the source to accurately match the nest where the wire is stuck. For example, if it is HDMI 3, then it is necessary to put the HDMI in the menu 3. From the laptop side functional key Fn + F3 or F4 (on different models Differently) select duplication mode.

PC connection

First, turn around, then change your own at your discretion. A similar action is made on a stationary computer, through the context menu of the desktop (Create Resolution Count "), both devices must be turned on.

  • Through the HDMI cable on the TV there is no sound, the image is available, what to do?

Incorrect Audio Flow Device personal computer. Click the speaker icon (right bottom of the screen). Eliminate the problem by pressing the playback device. In the window that opens, disable the playback devices, excluding the speakers of the TV. If necessary, also make an instance active (the string will become green).

  • TV stopped seeing HDMI.

We will risk assumed, the breakdown was preceded by the change of equipment. Installed new video card. Seeing such an outcome, the TV could reset the settings. Start first. The management is given above. Check the signal source, assignment. Any parameters for sound, images.

  • The laptop does not see the HDMI TV.

You need to choose the right source of the TV signal. Enabled devices must see each other. There is information that cables different versions Standards are incompatible with equipment. If there is V1.3, the technique has worked, the replacement V1.4 provoked the disappearance of the picture. Sometimes the video card setup requires the addition of the second monitor manually. Actually relative to desktop computers.

See: Causes (TV does not see HDMI) a little. Mainly adjust the equipment. Specialists recommend putting new firmware TV, after the device is turned off, pause 5 minutes. It is permissible to restart the product manually (help menu), for each model, the exact sequence of actions is different: lg, sony, samsung - the device demonstrates features. Act according to the management. Farewell council. Try surely alternately ports of the TV, changing the image source through the menu. There were cases from four HDMI nests worked the only one, for example, fourth. If we see movies, there is no difference, number 1, 2, 3 ...

Readers must understand: Operating windows system non-ideal. To work equipment, you have to restart the devices several times. It happens, the pro is asked why the digital technique refused? The master shakes his shoulders, says Windows - Must Die, Linux - Well done. Find it difficult to say that the phrase means, but for some reason the complexity on the forums relate to exactly paid operating systemand not freely distributed. I do not see the point of discussing on.

HDMI is a popular connector for pairing various techniques Between yourself (for example, computer and television). But when connected, different types of complexity can occur - technical and / or software. Some of them can be solved on their own, to eliminate others it may be necessary to hand over the technique for repair or replace the faulty cable.

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

Check HDMI ports on a computer / laptop and television. Pay attention to these defects:

  • Broken and / or rusted, oxidized contacts. If those are discovered, the port will have to be replaced completely, because Contacts are its most important component;
  • The presence of dust or other garbage inside. Dust and garbage can distort the running signal, which will cause inconvenience when reproducing video and audio confent (quiet sound or its absence, distorted or braking image);
  • View how well the port is installed. If he is at the slightest physical impact It begins to fall out, it will have to be recorded either independently or with the help of specialized services workers.

Perform a similar check of the HDMI cable, pay attention to the following items:


It should be understood that not all cables meet all HDMI connectors. The latter are divided into several basic types, each of which has its own wire.

Method 1: Correct TV Settings

Some television models are unable to independently determine the source of the signal, especially if any other device through HDMI was connected to TV. In this case, you will have to re-drive all the settings. The instruction for this case can be somewhat changing from the TV model, but its standard version looks like this:


Some TVs may look somewhat different. In the 2nd point instead of the proposed options, enter the TV menu (button with an appropriate inscription or logo) and select Option hDMI connections. If there are several connectors on the TV, then do the rest in accordance with paragraphs 3 and 4.

If this method does not help, use the instructions for the TV (it should be written there how to make an HDMI cable connection to a specific device) or pay attention to other ways to solve the problem.

Method 2: Computer Setup

Incorrect configuration of the computer / laptop with multiple screens is also the reason why HDMI connection is ineffective. If no external displays are connected to the computer, except for the TV, then this method You can not be considered, since problems occur if another monitor or other device is connected to a PC or laptop help HDMI (Sometimes other connections, such as VGA or DVI).

Step-by-step instructions for working with multiple screens for devices on Windows 7 / 8/8.1 / 10 looks like this:


It is worth remembering that HDMI is able to provide a single-threaded connection, that is, the correct operation is only with one screen, so it is recommended to disable unnecessary device (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 on 2 devices at the same time. If you are satisfied with the quality of the broadcast, then change something optional.

Method 3: Update video card drivers

Initially it is recommended to find out the characteristics of your video card, as some graphic adapters You are not able to support the image output at once on two display. You can find out this aspect you can view the video card / computer / laptop documentation or using third-party software.

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


Also, you can also download drivers and install from the Internet, be sure to from the manufacturer's official website. Just specify there in the appropriate section of the adapter model, download required file. By and install it, following the instructions.

Method 4: Clean the computer from viruses

Less frequently, the problem with the signal output from the computer to the TV via HDMI occurs due to viruses, but if you didn't help any of the above, while all cables and ports are working, the probability of the virus penetration should not be excluded.

To protect yourself, it is recommended to download, install any free or paid anti-virus package and regularly hold a PC test for hazardous programs. Consider how to start checking the PC to viruses with antivirus (it is paid, but there is demonstration period For 30 days):


Problems with the connection of a computer with HDMI to the TV occurs infrequently, and if they are also manifested, they can always be solved. Provided that you have broken ports and / or cables, they will have to be replaced, otherwise nothing will get out.
