Cobra,
You might try it without powerstrip first. When you move the cursor to the edge of the screen it will scroll to the edge so all desktop controls are still available. I have the same video card and just installed the Cat 4.2 drivers. Under the display tab you can click on the TV monitor button then to the advanced tab. Here you can adjust screen size and position. If you are lucky, it might fit. You will also need to edit the Aces High Video config file to your screens native resolution.
Yup, if you are careful not to leave static images on your screen, you should be OK. If ya get it workin right it really is AWESOME!
Dave
