I have a ProView 15" monitor.
Yesterday, out of the blue, it started freaking out. Every five seconds, it sounded as if internal switch was being flipped, and every time it clicked, the display became skewed in a different way. Nothing on the screen is readable, it is just a bunch of horizontal lines. Occasionally, it would stop doing this and return to normal..but only for 10-20 seconds, then it would return to this cycle. I attempted to reset the monitor, but this did nothing. Also, I unplugged the monitor from the computer and turned the monitor on. It continued to do this. Therefore I do not think it is a software problem. Any ideas what happened? The other day I was experimenting in some obscure graphics modes in DOS (like 640x480x256)...could this have possibly damaged the monitor? If so, the damage didn't manifest itself until a day later.
I have no access to any of the monitor's controls (as far as I know), because these are menu-driven, and depend on the screen. I think I will have to RTFM, but if anyone has any ideas on how to remedy this I would appreciate hearing them. Thanks.
