They wonder a lot: why the TV does not work HDMI-connection, because the cable is new, the signal was right, and the switching of the extensions was carried out according to the instructions.

In another case, for example, at the same time, a TV set and a display are connected, followed by additional adjustments.
At the working table, you will need to right-click on the mouse on the free field of the working table, after which go to the "Screen permission" menu (for Win7) or "Graphic characteristics" (WinXP) and select the option of duplicating screens. For laptops, there is a special functional button at the top of the keyboard from the image of the monitor icon (sound F4).

The reasons why when connecting a computer via an HDMI interface there is no image on the TV, there may be a lot. We will try to look at the widest of them.
Fixing the TV input
In the first turn, go to the TV menu and check whether the input signal is the same HDMI port, before connecting the cable. On the rear or rear panel of the TV, there may be a few ports, and leather of them may have their own index (HDMI 1, HDMI 2, HDMI 3 and so on). Therefore, you should know on the TV remote control and press the button to select hello dzherel signal. You can also use the Source (Dzherelo), Input (Input) or HDMI button (the skin picker has its own meaning).
In the list of inputs, which appeared, next select the one to which you connected the HDMI cable that connects the TV with the computer. After selecting the required input, confirm the entry by pressing the OK (Enter) button. Now, on the TV screen, you can see a mirror image of the computer desktop. If the screen continues to be black, it means that there is a problem with the computer's video card being installed.
Computer video card upgrade
It is quite possible that the video card is not assigned to the installed video cards, that the TV set is victorious as an additional monitor, so the image is sent only to the computer monitor.
To solve the problem, click with the right mouse button on the free field of the computer desktop. In the list, find the item “Screen options” (for Win7) or “Graphic characteristics” (for WinXP). There is a special menu, in which you can choose options for choosing the main and additional monitors. The most convenient option is to clone (duplicate) TV screens and computer monitors. After pressing the OK button, an image may appear on the TV screen.
When the laptop is connected to the TV, the procedure for selecting the screen looks much simpler: you need to hit the two functional buttons Fn + F4 on the keyboard at once, until the option appears that pleases you. Deputy F4 may have a different button, a pictogram with one or two monitors is applied to which one is responsible.
Mechanical failure
Well, the remaining reason, as I explain why, when connected via an HDMI interface, there is no image on the TV, is the failure of the cable itself or the communication ports on one or both of the outbuildings.
There is no insurance for the factory cable, so if you have problems with the connection, you must check the correctness of the HDMI cable. The easiest way is to change the yoga cable by replacing it with a guaranteed reference analogue, or try connecting it to other extensions.
A common reason for the failure of HDMI-ports to operate is incorrect cable connection to them. Crim of mechanical failures of internal contacts, the port may suffer through problems with static electricity. Wanting the HDMI standard and supporting “hot-pluggable” equipment, but through the day with our larger by-button technology Normal ground and the HDMI port will continue to light up. Therefore, it is necessary to inform meistri before connecting the HDMI cable to the equipment, and from the TV set, additionally remove the antenna plug.
