So a while back my Dell 20.5" monitor, after using it for a little while, would occassionally get messed up. A thick bar would go from the top to the bottom of the screen (2-3 inches thick). I figured my monitor was ruined as they are fairly old now.
I have only 1 monitor hooked up to my desktop, and I have another similar monitor. So I put that aside and hooked up the new one, and it was fine for a few weeks and now it is doing the same thing.
As I type this it happened again, and the colors are light purple, to blueish colors and it is about 1/3 of my screen.
Since it happened now to both monitors, could it be the cable or video card that is the problem?
Actually I always use the monitors own cable so they are not using the same cable so that's probably not the issue.
