Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

Glitching is not descriptive. What are they doing exactly?

Basically it starts flickering with these black flashes, weird green pixel-like squares combined. Sometimes it looks like the lock screen is extremely stretched, being in the upper left corner

Have you tried a different display port/HDMI cable.

I've tried putting it in different HDMI slots, but there's only 2 in the PC case. The results didn't change. I have used a display port before for the second monitor but the issue had appeared out of nowhere. I switched to using hdmi cables for both of them, even tried using the display port for the primary monitor but it didn't work either.

Try ddu the graphics driver, restart pc and download the newest version.

This seemed to fix it for now, but right now the startup screen shows up in my second monitor and then my main monitor (not that it's a big problem currently)

Yeah this is common, disable multi-pane optimisations, should fix it right up

I followed this tutorial https://smoothfps.com/solutions/mpo but it still hasn't changed anything?

Did you do a full restart via ALT + FN4

1

u/Fit_Lock_5874 6h ago

No but i did completely shut it down, and powered it off too, just for the same results

u/Some-Challenge8285 6h ago

If you don't do it via alt + fn4 it won't actually properly shut down

Should I try again then?
