XB273K HDR mode leads to flickering in apps and games

andimiandimi Posts: 1Member New User
Hello,

When I use the monitor in HDR mode (Windows 10 latest version, either using applications or gaming, e.g. Firefox or Slack app or Sekiro game when using HDR), the screen flickers slightly but noticeably. It's almost as if the backlight is flickering for a few milliseconds, but I am not 100% sure that's what's happening.

I tried lowering the frame rate, but this problem persists, but when HDR is off, the screen has no flickering problems at any frame rates.
This happens when using a display port or HDMI port (I am using HDR compatible cables, and multiple ones in case the cables were defective - the problem still persists).

This is annoying and over time it led me to disable HDR altogether. I wonder whether it is a driver issue (I tried both an NVidia 1070 and now a Titan RTX, and the problem is present in both) or a monitor issue.

What shall I try? I would appreciate any suggestions.

Cheers!
