Artifacts only at 180/200Hz on new monitor

Hi,
I recently bought a new monitor (KTC H27T6) that supports up to 200Hz, but I'm having a strange issue.

The monitor works perfectly fine at lower refresh rates (144Hz), but when I switch to 180Hz or 200Hz I start getting visual artifacts on the screen. The weird thing is that the monitor OSD looks completely normal, so the artifacts only appear in the PC image itself.

What I already tried:

  • different DisplayPort cables
  • different GPU ports

The manufacturer suggested it could be a bandwidth/signal issue.

Has anyone experienced something similar or found a fix?

Thanks.
