I have a setup with 2 monitors
When i turn on my pc and start working, one of my screens starts turning on and off after about 30 minutes.
At first it turns on and off about every minute but after a few times it just stays off.
The only solution i have found to this is running a game in the background.
When i run Rocket league in the background it stops doing this and i can continue working on other things.
I have tried an other monitor and other cables but nothing helps. When i only use one monitor there is no problem.
