2nd display turning off all the time

[M4rk4yy]

Hello everyone!

 

So, I already got this problem a few months now and do not know what to do anymore. In short: I got 2 displays, one main screen, one secondary which physically is left by the main one. My problem is that the secondary one always turns off after a few minutes. Sometimes turning back on, then blacking out again randomly. The monitor literally turns on standby, as if someone had pulled out the cable out of it.

 

Things I tried already:

- Setting the secondary monitor as the main one in Windows settings

- Using like 5 million different HDMI/DisplayPort cables

- Different GPU Outputs

- Different GPU (Had to upgrade anyways)

- Playing with the monitor settings for something like a power-saver mode

 

Things I will try as soon as I got the money:

- Buy a new monitor
