ive been running around trying too find different drivers etc and i can not seem to get my tv to display anything other than the desktop picture. funny thing is it shows the picture but nothing above it if i am using a window on my main screen. i simply am trying to use the tv as my display to play movies. it is a sony kdf-e42a10. the computer is a dell inspiron 8100 with a nforcego proc. running windows xp. i had read on some threads of trying to set your resolution to a 16:9 specific ratio but the one suggested is not available in my main displays resolutions. the tv shows an active desktop up intill the windows loading screen then reverts to just a the picture on my desktop. i cant seem to select it as my primary display either?
