I have a Dell Optiplex SX280 with integrated GMA900 graphics (915). I am trying to drive an LCD TV (tried two different ones) at the native 1920x1080p resolution.
Unfortunately it is not an available choice, contrary to the White Papers on the GMA900 that list HD resolutions as supported.
All I get is 1600x1200 and 1920x1200, which both work fine. If it can do 1920x1200, then surely 1920x1080 would work!
I've tried both XP and Vista -- neither offer 1920x1080 as a resolution.
