Since yesterday I noticed there were scan lines visible on my monitor. I didn't think much of it but the issue persisted after I turned off my monitor for ~20h. Can't figure out if it's my monitor or GPU causing the issue since I do not have a second display at my desposal. Ran a stress test on my GPU which did not worsen the issue, replugged my cables and resetted my monitor. Both of which did not help either.
Does this mean I have to get a new display or GPU?
