i have a GEFORCE 7200 GS screen card from NVIDIA which i never had any problems with before. windows (xp) alerted me of an update for it so i installed it but all it did is take out all the settings options from when i first installed the cd drivers. so i reinstalled the original drivers (overwriting the new ones) and now my chosen screen resolution of 1600X900 pixels is displayed "letterboxed" and "shrinked" with black bars from both the sides and top and bottom. as if i'm watching a letterboxed 4:3 video on a 16:9 screen which is not the case. tried adjusting the resolution again to both lower and higher, most do fill the entire screen but not 1600X900. my screen is Philips 228C3LSB (LED). any help will be appreciated.
