Hi All, Just doing some game compatibility testing on my laptop (Vaio VGN-A517B) which has an ATI X600 256MB graphics card. I am using Vista Ultimate (via MSDN) but cannot get a number of games (specifically WoW) to increase the screen resolution past 800x600. I have used the default Vista drivers and the lastest notebook ATI drivers, both with the same result. Can anyone shed any light on this for me? Thanks Vortal
