Just installed an ASUS MS246H monitor, with HDMI. I have a similar problem to the below message (same as others)posted on Newegg:
Other Thoughts: I also had a problem with the hdmi not taking up my full screen with my ATI HD 5770, but it turned out it was actually a problem with the gpu. I turned on catalyst control, and changed the overscan to 0. This fixed everything. Make sure you have the most recent edition of catalyst control center.
I have an ASUS MOBO M2A-VM with AMD processor. The MOBO has an onboard video card ATI Radeon Xpress 1250, driver ati2dvag.dll version 5.14.10.6666. Also have the Catalyst Control Center.
ASUS does not have a newer version of the CCC to download. The AMD site has one, however, when I tried to install a Microsoft message came up and said if I continue it could screw things up, so quit the installation.
Am I missing something on where to change the overscan? Looked everywhere and cannot find it. Or, is there some other way to eliminate the 1/2-3/4 inch black border wasting the screen space?
Thanks once again for any and all help. Golf
