Any advice on this would be very much appreciated. Here is a video to show you exactly what is happening: Acer X34 flicker - YouTube Flickers occur at 0:24, 0:48, 1:12 and 1:15.
My full system specs are:
16GB Corsair Vengeance LPX 2133
ASRock H170 Pro4
Gigabyte R9 390X
The new monitor is an Acer X34. Ever since I connected it I have been experiencing this annoying flicker. If I disable DP1.2 and change it to DP1.1 the flicker goes away, but I need DP1.2 for the Adaptive Sync stuff. The frustrating part is that if I uninstall the AMD graphics drivers, the flicker also stops, and it doesn't flicker when in the BIOS or safe mode. I am really unsure where to go from here and would really appreciate some advice. It may also be worth mentioning that I have tested the monitor with my sister's computer as well, who is using an ASUS 290X (different driver but still AMD) and it still flickers. The flicker looks slightly different with her computer but it's still there.
Please help! Thanks so much
