I bought a 144hz Acer monitor from Amazon. I noticed it would occasionally flicker black for a second or two then come back when playing games - I've never seen it happen when I'm outside of a game. I got a better DisplayPort cable and tried again. Issue would still happen every few minutes. So I ended up returning the monitor and bought an HP 25x from Best Buy, which is 144hz over DP and HDMI. I tried it with DisplayPort, and had the issue. Switched to HDMI, eventually got the same issue. I have other monitors plugged in and those two have no flicker issue. I set another monitor as the main display and STILL had the problem occur on the 144hz monitor, while the game was playing on my 60hz monitor. I've tested this issue with FreeSync on and off, and it occurs either way.
This does not occur in 60hz... I've gone as far as formatting my PC. is my card just defective? I got it about 2 months ago.
