Monitor not working correctly.
Out of the blue the other day I get the following message on my screen. "Not optimum mode recommended mode: 1280x1024 60 Hz" I'm not sure what I've done to get where im at right now because I'm currectly using the problamatic monitor but....if I go change the resolution to anything other then 800x600 that it's currently set at, my entire screen will go blank, and stay blank. I'll reboot and end up with the same message. Is this a problem with my monitor or my video card? I've been using this monitor for a couple of years and I've never had a problem with it. Whenever the Not optimum mode message would come up on my screen I'd plug a different monitor into the computer and I was able to view whatever was on the screen no problem. Please give me a solution to my problem.
