I have a dual monitor setup. Normally, they both display at 1680x1050. They have been setup this way for about a year. I'm using Windows XP Professional 2003 x64 SP2.
Today, out of nowhere, one of the monitors kicked back to a lower resolution. I was not playing with any configuration at the time.. in fact all I had done was close a window (maybe a browser). But the thing is that the resolution is still preserved partially by the fact that the screen will scroll when you move the mouse. So it's like looking through a 1024x768 window into a 1680x1050 world.
The monitor itself does not appear to be damaged, because I also have it connected to my netbook (via KVM) and higher resolutions work fine.
I tried uninstalling/reinstalling the drivers to no avail. System restore doesn't help either.
I'm unsure of the exact ATI card I'm using.. Device Manager lists it as "Radeon X300/X550/X1050". There is no Catalyst Control Center software installed. I tried to install it, but there doesn't seem to be a way to install it by itself ... it forces you to install another driver, which breaks both of my displays, forcing me to go into safe mode and run system restore again.
Any ideas?
Thanks
EDIT:
After playing around more, I discovered that the "scrolling" behavior is only present for aspect ratios that are not 4:3. For 4:3 ratios, it just stretches out to fit the wide screen. My monitor's native ratio is 16:9 .. what could be causing it to think it needs to scroll?
