I've had a Dell M992 monitor at a 45deg angle in my current build, a Star Wars upright. Turned it on today and I have discolouring around the top edge.
Tried degaussing but it didn't help. I then took the monitor out of the cab, put it level, and it looks fine. Back at an angle, looks bad, even after degaussing again.
Any idea what could be causing it? It's been fine for weeks.
