I just completed a fresh Windows 7 install with my P8P67 Pro MB and 2600k processor. I'm using the same 5850 video card. I'm pretty sure the last drivers I used (11.2) let me select GPU Scaling and Maintain Aspect Ratio. I installed the 11.3 with the rebuild, and while I can select Enable GPU Scaling, the other options are grayed out with a permanent selection of Scale Image to Full Panel Size, which I don't want. My HP ZR24w monitor can't rescale itself and needs the video card to do it. Is this a new "feature" or was it left over settings from previous driver installs that I could even do it on the last Cat series? I've seen this discussion on the AMD forums but no real resolution or idea why it's this way.
