Solved M27Q X monitor sometimes flickers black for a couple seconds then back on

Guess DDU didn't do much, as soon as I opened Adobe Illustrator suddenly I had my GPU installed again...

I've used DDU in Safe mode to completely remove my graphics drivers and test for a while.

Your computer to do with as you see fit but if you want to do your own thing we will put your thread on hold for now until you are done, we cannot safely advise members that do not stick with only doing as is advised here at PCHF, we cannot be held responsible for other peoples screw ups that way.

When you are done with doing your own thing if you still need help to avoid any repetition let us know what has been tried + what any outcome was.

Any updates ?

Shifted some cables around including electrical and now waiting on a shielded DP cable, then will report back.

Any news?

I was waiting for a solid week of normal use to report back but I can do it now.

Since switching to this shielded DP cable, the flickering the stopped completely. I'm guessing it might be do to living in a 40 year old apartment and the main outlet that's connect to my PC is less than 40 cm away (15 inches) even though the PSU isn't directly connected to it, there's surge protector power strip in between where everything else is plugged. A lot of the display cables were also fairly close to it or even touching, something I did change, though had little effect before switching cables.

Either way, the issue appears to be gone.

Excellent news. Thanks for the update.

Will close as solved.
