What's wrong with my display?

[VGS_XD]

The display in question is samsung SyncMaster 971p to whom it may concern, this started happening recently, and it doesn't happen on my other display. i tried switching the display outputs, but nothing changes. the first image is of my HDMI display and the 2nd is from the display in question, i know the pic quality is poop but artifacts are clearly visible. I tried running the HDMI display on DVI to check if my port is broken but no artifacts occur.

Addendum: the issue fixes itself when i physically pull the cable out of my pc and plug it back in, and it stays fixed until the next startup. Also it started happening after i updated to windows 10 May 2020 update.

So you don't have artifacts with DVI? Have you tried a new cable?

I could try to run the display trough an HDMI cable using and adapter, but i dont have any spare DVI Cables to test.

The cable might be the one to blame here, i switched the outputs on the displays and rebooted my system and now its the HDMI Display that's having issues. but then that doesnt seem like its the cause as the issue fixes itself when i yank the cable out of my gpu and plug it back in, so maybe windows update fucked something up, like it may be trying to run the display at 10 bits or smth

Sounds like a cable issue if replugging works.
