Hi there,

I've had this screen for about 5 months , never had a problem , but a few days ago it started having problems.
As soon as i start up a game the screen will go black and the input light on the screen changes. It behaves differently for each of the 3 games i have installed:
- With World of Warcraft it will only loose input signal when theres an ingame loading screen , same goes for PUBG.
- In Overwatch as soon as im in the menu it starts going back and forth from black screen to normal screen with estimated 1 second intervals. When this happens the indicator light on the screen will change colors back and forth. I want to point out that the 2nd screen (connected through dvi-d is fine during all of this , the acer displays the desktop just fine when i alt-tab out of the game when the issue occurs.
The way to fix the problem is to remove the DP cable from either the screen or the GPU and plug it back in : problem is gone. I can then game without issues for the rest of the day.
Obviously i do not want to keep re-plugging the cable as obviously something is wrong.
What i have tried so far without a fix: 
- Install the latest nvidia drivers ( aswell as an older one)
- Try a different cable (used the one that came with the screen aswell as a brandnew VESA certified one from Startech.
- I couldnt reproduce the problem on my 2nd screen. (this method isn't waterproof though as removing the cable fixes the problem)
- Fiddled around with all sorts of nvidia control panel settings.

If anyone has the slightest idea on how to fix this i would gladly hear it :)

    For those interested , i think i've fixed the issue. I did a GPU bios update from nvidia which updates the DP ports , also changed the powercord of my screen to its own socket in the wall. Not sure what fixed it or if it's even fixed , but didnt have a single problem 4 days straight now. it would happen ast least once a day before.
