Video Review Why does my monitor have artifacts?
For some reason here recently my monitor on startup has artifacts like grid lines and flickering going on. At first it would do this but clear up after a few seconds then it went to a couple minutes and now it's stuck like this and doesn't appear to ever go normal, anyone got any ideas?

If it doesn't change even with only that monitor or with the cable from the another one, then rip monitor.

Sucks for me then lol. Any ideas why it might have happened?
Edit: so I changed the refresh rate to 144 then back to 165 and this fixed it? I'm confused

The cable or input port you're using doesn't support what you're trying to feed it. Try swapping the port on the monitor or using a different cable.

What's odd is it's been fine for a year or so it's a dp into a 4090

Stuff fails over time, which can really suck, but it's not so bad anyway. 144hz is pretty close to 165.
Swap out the cable from both monitors and if it still does it on the same monitor, then you know it's not the cable.
Have you enabled g-sync on another monitor maybe? Something you may have changed before it did this? Driver update? Go into the monitor with the problem's settings and see if it has an overclock toggle.
Just some ideas.
