my monitor is no longer recognized, screen resolution is decreased
I installed Windows 7 Ultimate 64bit SP1 on my replacement boot disk (old one died) on May 25/12. Since June 4 (and at least once before that), daily my monitor is no longer recognized and the screen resolution is decreased. It doesn't know about my Samsung monitor anymore.
It now shows this:
Display: Generic Non-PnP Monitor, Resolution: 1024x768.
When I run personalize, screen resolution, detect,
Windows sees the correct monitor (SyncMaster 245B(Analog)) and sets the resolution to 1920 x 1200. Meanwhile all my open apps are resized smaller, I have to resize them again.
I'm not sure what the cause of the problem is. It's not necessarily happening at the same time and I can't seem to find an error in event viewer. Any ideas how to troubleshoot and resolve this issue?
