My monitor suddenly out of nowhere started having weird greenish white pixels that move, the screen shook, and then would turn blue and say invalid signal. It was fine just an hour or so before I left for an hour. What could cause this and how do I fix it?
I have done a little trial and error work and research. It does it in Windows and Xubuntu. It's not the resolution. YES I have tried other monitors. In forums I have read it was like every other person say try another monitor. I switched to onboard graphics and the problem was there. I have suspicion it's my graphics card.
I have an HP a6110n with a nVidea 9800GT on a Vizio Razor in a native resolution of 1920 x 1080. Yes my monitor doubles as a TV and is technically a TV first, but this has not been a problem in 9 months I have had it.
I have yet to try it but I am going to swap graphics cards with another computer to see if it does it to that one and if it doesn't on mine.
