The M27Q X monitor occasionally displays a brief black flash lasting a few seconds before resuming normal operation.
This problem has been recurring multiple times daily over months. My M27Q X monitor is linked via DP to a RTX 4080, while an older HP22w uses a HDMI cable. The issue appears only about 95% of the time with the main monitor and occasionally with both simultaneously. It causes a brief blackout lasting two seconds before returning to normal. I've tried reinstalling drivers, using new cables, repositioning cables, changing GPU ports—nothing resolves it.
