Multiple monitors windows pc?

I have a computer with Windows 8.1.

I wanted to connect my TV to HDMI in addition to my VGA monitor. It is also recognized by the PC, but the television says that no signal is received.

I also tried the TV in the living room and it didn't work either. The HDMI cable is not defective because I was able to connect my laptop without problems, for example.

I have read on many forums by now, but nowhere was the right solution.

Is due to the driver of the computer… You need a better HDMI driver

Where did you connect the cables to the PC?

On a graphics card or on an on-board chip?

What happens if you only use HDMI and omit the VGA?

Stupid question: is there one you can recommend to me?
