So I bought the monitor Acer KG271Abmidpx few weeks ago. Monitor is connected with DP cable, which was included in the box. Most of the monitor settings are default (DP 1.2, Auto Source, etc.). My Windows settings are - 1980x1080, 144hz. AMD Radeon settings - default, FreeSync - Off.

First problem happened when I turned on the Display with my PC in the morning - 1 or 2 days after the purchase:

I just turned the monitor off and then I turned it on and everything was fine... for that day...

On the 4th or 5th day I was playing game and when I "Alt+tab"-ed the game this happened:

I tried HDMI @ 120hz and didn't have problems, atleast for the test period.
What is the problem? What can I do? It's hard to explain this problem in the store if they don't see these videos.
