I upgraded from windows vista to windows 7 yesterday. The upgrade went fine and windows properly detected the screen resolutions, but when I selected 1920x1080 it worked but I got black sidebars. This was using the latest driver release from Ati. I also noticed that the selectable refreshrates missed the 75hz option that used to be there in vista.
Now I downgraded the Ati driver to the xp version, this fixes my sidebar problem. But since the driver isn't WDM signed AERO doesn't work.
Has anyone encountered a problem like this before.
