A:Answer I had the same issue, I was using it for my PC so I did some tests to see what it could be. I made sure all connections were secure and fit. I had it on HDMI, so on regular screen use it was fine but when it came to gaming it would turn on and off at times. I can’t tell if it’s cause of the refresh rate but I tested 144 Hz and 120 and even 60Hz and it still flickered. The other test I did was use a different HDMI cable and nothing, then I used a different monitor to see if my GPU was incorrectly installed possibly and the other monitor ran smoothly. What finally solved the issue was using the Display Port and not the HDMI. I would’ve stayed with the monitor because the quality and design was great especially the stand, but I didn’t want to keep it since I considered it defective.
