Display resolution problem

I am running Windoes 7RC, Build 7100. My monitor is an HP w2007. All of a suddent today, the display on my screen refuses to fill the entire screen unless I put the resolution on the recommended resolution of 1680 X 1050. At that resolution, I have to set the DPI over 160% for the text to be big enough to read. Except in Firefox everything is really, really large - while in Inter Explorer, all the Office applications, and everything else the fonts and type is small. Does this give any insight?

I had not made any hardware or software changes before this happened, and I was able to run the resolutuon at 1280 X 800 and have the entire screen filled. I tried uninstalling the graphics drivers and the Catalyst Control Center - made no difference. Does anyone have any ideas?

You're not having much luck Stephen. I can't even find anything helpful by searching.

I'll give you a bump and see if it generates any input.

Have you checked you graphics cards control panel settings for the set aspect ratio/scaling:
