Black bars top, bottom, and sides

[box o rocks]

I just finished a new build. All is well except the display. I have a HD 6870 connected to a 24" Asus 1920x1080 monitor via HDMI. After installing the latest AMD driver, I had an underscan display when I booted up. I had to go into CCC and set Scaling Options to 0% to get the display to fill the screen. (It was at 12% as default) Yes, I made sure to click on "Apply".

But everytime I re-boot, the display is back to underscanning w/bars top, bot, and sides. The only way I can restore the display to fill the screen, is to open CCC and move the Underscan/overscan slider back and forth once. Then it snaps back to fill the screen.

Is there any way to make the display fill the whole screen... and stick?

Thank you for your reply. I am using Catalyst 12.7
But I may have accidently fixed it. I temporarily connected the monitor via a DVI cable and the problem was gone. I then switched back to the HDMI interface, and the problem appears to be gone. If it doesn't return, I may leave it rather than mess with the registry. But I will bookmark that thread, just in case.
