HDMI does not work on TV

HDMI port serves for high-speed media information. Often the situation occurs when the HDMI input does not work on the TV and the connected devices are not visible TV. This can happen, no matter what it is connecting to the TV: a laptop, a game console or another.

Before panicing, you should make sure that the correct settings were selected at the TV. Often the power source is not installed independently and select the image transfer from HDMI manually through the menu. Often the problem is that HDMI does not work and does not see the TV devices connected through this input, manifests itself when TV synchronization with laptops.

Immediately after connecting the cord from the laptop to the TV, press the keyboard key on the FNF3 keyboard (F4). This menu allows you to select the screen display setting. For example, you can choose so that the pictures from the laptop screen disappear, and was transmitted only to the projector (TV). Actually choose a duplicate transmission of the picture, in which the image is transmitted to the laptop and on the TV through the HDMI cord.

If via HDMI on the TV is not displayed picture, you can try to update the video card drivers. You need to do this through the device manager by selecting the “Drivers” section. In the general list, find the item belonging to the video card, and open additional information about the device through the right mouse button. In the latest versions of the Windows operating system (7.8 and 10), the driver update occurs independently when you click the appropriate command in the window that appears.

What are HDMI connectors and adapters

Inteeis HDMI is constantly developing. Developers will improve it. Therefore, the user should be aware of the existing modifications of this connector. Not always a new version of intees will significantly exceed the past. Sometimes the differences are so not significant that the usual user can not at all notice the difference.

Manufacturers are actively used backward compatibility technology. The essence is that each new modification has a list of the functionality of the predecessor. How to identify different versions of HDMI standard? First, each modification has a certain labeling. Secondly, they may differ externally.

hdmi, does, work, port, connections

Consider several of the most common versions of HDMI connectors:

  • Deep Color. Suitable for configuring a computer connection with a TV with an extremely rich colors palette.
  • V.Color. uses a range of colors that is not available TV operating on RGB technology.
  • Standard. a connector that supports this option will provide a video signal with a 1080p resolution at a distance of up to 15 meters.
  • High Speed ​​- Designed for video transmission with 1080p resolution, but at a distance of 7.5 meters.

Preparing, to configure the connection, consider the type of cable HDMI huge role. For example, some versions allow you to transmit a video signal with full HD resolution, and older modifications, on the contrary, are designed to broadcast images with not the best quality.

In situations where TV LG or device from another company is hanged on the wall, the traditional cable connection is incredibly difficult to implement. This is explained by the fact that between the rear cover TV, on which the HDMI connector is preferably located and the wall. the minimum distance.

The situation with a lack of space for the wire is solved by purchasing a special adapter, the form of which is a straight angle. If such an adapter is used, then with the connection setting, no difficulties will absolutely. The connection process will depend on where the connector is located: rear or television side.

Users planning to connect several devices to the TV on HDMI immediately, buy the so-called switcher. Switcher. adapter that allows you to connect to one connector multiple signal sources.

In continuation of the topic of adapters, we note that not all the TVs and computers are equipped with an HDMI inteeis. In such cases, special adapters are bought: VGA-HDMI, DVI-HDMI, USB-HDMI and T.D.

Stages of equipment checking

Checking cable

If a TV connected to the PC stopped working suddenly, and before that time everything was configured correctly, it means that the cable was departed or he was 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.

In any case, if there is no image, first check whether the connectors are inserted into both devices completely. And there is no foreign objects on the adapter itself.

On the laptop to do everything easier. Click simultaneously button “FM” and F4, keep until the optimal option is selected. After that, the laptop to the TV will be connected correctly and the error is that no image will leave.

Video card error

Another reason why device connection does not work. 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 a global network for each device model. Sometimes it may be necessary to fully reinstall or replacing the element.

Features HDMI wires and the main causes of malfunction

HDMI abbreviation is decrypted as high definition multimedia intees. This is a modern connector that simultaneously transfers audio and video. Almost all the equipment is equipped with this inteeis. Tulip and others popular in the past cables are intended to transmit analog signal. HDMI cord translines content in digital content with Full HD or 4K resolution (depending on the modification).

So if you need to connect a computer to the TV screen, then it is best to use this inteeis. The connector provides data transfer in the highest quality and with minimal delay. Unlike other wires, HDMI simultaneously transfers to TV sound and image.

Sound. Connecting a TV to a computer HDMI

Inteeis HDMI 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 choose a sound source. Now the TV is considered by the system device, so this responsibilities can be assigned to it. To do this, it’s easier to click the right lower corner of the desktop (speaker icon) of the right mouse button, select the reproduction 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 word selection of the 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, use. In 90% of cases in a couple of seconds, native plasma panel speakers will sound. We want the sound around? Such an acoustic system comes with a home cinema. Polyista Description of the device. A number of ways are offered to transfer sound from the TV to a home theater, anyone will suit, given the condition for the need to purchase the required cable. Similar to the home cinema control panel with the source button, select the desired sound source.

Coupling problems: why the TV does not see HDMI connection

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 switching of devices was carried out according to the instructions. The reasons for this state of affairs may be somewhat, so the search for a problem should be sequentially. I mean in advance that you are using a “HDMIHDMI” type cable without any intermediate adapters.

Check the health of the HDMI cable. Even very expensive brands are not insured against such a thing as a factory marriage. In addition, due to non-accurant operation, the cable may be damaged. Check the HDMI cable can be replaced by a safe analogue or connecting to other devices.

Check if you chose the input source in the TV menu. To do this, on the remote control of your TV, click the outer login button. Depending on the TV model, it can be the Source button (Source), Input (Login) or just HDMI. When you click on it, the menu will fall from the list of available inputs. Select and confirm by pressing the ENTER button (OK) that input to which you turned on HDMI cable.

Check if the mode of working with an external monitor is selected on your computer (in this case with a TV). If the TV is the only monitor connected to your computer, then it must decide automatically. Otherwise, for example, a TV and a display is connected at the same time, additional settings should be made.

In the desktop it will be necessary to right-click on the free field of the desktop, after which go to the “Screen Resolution” menu (for Win7) or “Graphic Specifications” (WinXP) and select Options for Duplicate Screens. For laptops there is a special function button at the top of the keyboard with the image of the monitor icon (usually F4). Pressing it several times simultaneously with the Fn button (for example, FNF4), select the appropriate option to use the external TV screen.

Ensure that your computer has the most current versions of the drivers for the video card. In the Computer Device Manager, determine the version of the video card driver used. On the official website of the video card manufacturer, find the most current versions of the drivers and download and install them on your computer. Sometimes problems with HDMI connections arise due to the use of an outdated version of the SMART TV Operating Platform.

Check the computer operating system for its infection with viral and malicious programs. You should check the computer with any effective antivirus program with fresh signatures.

Check out the health of HDMI ports on the TV and the external signal source. Connectors can burn or be mechanically damaged due to a multiple violation of the Cable Connection Procedure. Although the HDMI standard allows “hot” cable connection, but experienced professionals are recommended at the time of switching not only to turn off both devices from outlets, but also disconnect an antenna cable from the television socket.

Another fairly exotic reason why the TV cannot see the computer via an HDMI connection is the lack of additional nutrition on the discrete video card used in it, and after all, working with an external device requires increased energy costs.
