Why does the TV not see the PC?

Question

Computers

I assembled the PC, connected it to the TV, but writes that there is no signal. Connectors are correct. I decided to check and connect to another TV, but the result is the same. In the box with the motherboard was a disk with drivers. Unfortunately, there is no disk drive in the case.
How can I fix the problem?

Answer 1

Update video card drivers online. Use the sourse button on the remote control to select the HDMI signal source.

Answer 2

On some cards, it happens that the TV needs to be turned on before the computer

Answer 3

Change the cable, three out of four fail me regularly. Lie down - they start working again. Why - xs. There is no static. Two long - 3m, one 1.5. Short is much rarer. Better buy a new one, for two rubles. Check cable version 1.4 or 2.x. Resolution setting on the TV. Connect better when the TV and system unit are turned off (from the outlet!) And completely discharged (turn on the power button, if any, with the plug pulled out).
Also, check the output on TV, give it a name - PC, for example.
