Subtle brightness flickering on XB281HK
Hello everybody.
I just recently got an Acer Predator XB281HK and while I really like the monitor very much, it has a very annoying issue. What is happening is that whenever shades of grey are displayed on screen there is a very subtle and very fast brightness flickering going on. All other colors seem to be fine so it's a very specific issue. This is very visible when overdrive is set to Extreme and applications that have interfaces with shades of grey are used (e.g. Photoshop, Adobe Premiere etc.). Also this issue might not be visible to people with not so sensible eye sight.
The issue can be mitigated by setting overdrive to OFF but the problem is definitely still there. Turning off Gsync doesn't help, the issue is still there so I believe it's a problem of the panel itself and not of the Gsync module.
Needless to say that I tried basically everything to sort this out (change cables, reinstall drivers, change refresh rate, change settings in Nvidia control panel etc) but nothing helped.
Just checking if anybody else had the same problem and if technical support can fix the issue by replacing the panel or updating the firmware.
The monitor is basically unusable for me as it's causing headaches due to this constant change in brightness of grey colors.
