I recently bought a rx 580 and I am having major issues. I've had this GPU for a week and am unable to play video games because of my screen flickering and going black completely for 2-3 seconds. This issue only occurs when I am playing games, and when I use my displayport. I have tried using a VGA cable from the GPU and it works but if I have to do this I'd rather return the card. I have a 144hz moniter and would like to take full advantage of the extra hertz. Thanks!
