hi there would really appreciate any help on my peculiar display issue.
to preface this, my HW specs:
asus rampage vi extreme encore
2 x 2080ti evga ftw3 ultra
8 x 8 gb g.skill tridentz 400mhz cl17
1600w evga t2 PSU
display 1: acer x27 = 4k 120hz HDR
display 2: acer xb271hu = 1440p 144hz SDR
nvidia driver 442.19, i have vsync turned off global
windows 10 pro version 1909 OS build 18363.657
i am not listing storage, fans, cooler as i do not think they are relevant
ok so the problem. both displays are hooked up via display port to a single GPU. i have both set to 120hz
when i play videos from youtube or other embedded video players, when i go fullscreen i get the phenomenon that is in the attached photo only on display 2, i can use display 1 just fine. or follow this link https://imgur.com/a/3ZqxlT4
i can see that in the "white space" that the video is still playing. the only way to solve this is to un- and re-plug display 2
this is the worst issue, another issue i have is that when i open WhatsApp windows store app, i get horizontal flickering in the centre of the screen, with a width of 2-3cm i want to say. when i play games that problem goes away and begins again once i stop and the only to solve it is to restart the computer or replug the display.
steps taken to try to solve:
1. bought new displayport cables for both displays
2. bought new mobo, i used to use the asus rampage vi extreme
3. switched GPUs around
4. tried different displayports on the GPU
5. DSR on display 2 to match 4k <- i started having GPU crashing issues sometimes on the desktop. i could never find a causation but i would never get the same problem as in the pic so it is a "solution" of sorts
6. reinstalled a fresh windows 10
i play games no problem, from hearthstone to battlefront 2 to witcher 3, metro, borderlands 3, etc. nada no issues.
i am lost and as you can imagine it is not easily google-able. i am assuming it cannot be the GPUs because if that were the case then that means by some stroke of bad luck BOTH gpus have the same issue as it happens on both
