Hello. I have a Desktop with a ATI Raedon HD 4500 Graphics card installed and also have a Acer P235Hbmid Black 23" 5ms HDMI Widescreen LCD Monitor 300 cd/m2 50000:1(ACM) that Im using. I just rebuilt my desktop and installed all the current video drivers and also that Catalyst Control center and none of the resolutions on the Display Properties work for me... as in I cant get my monitor to show my whole desktop, only a smaller square of it on all resolutions. Any help? :/
