proprietary

I installed the proprietary driver (fglrx-updates) on Ubuntu 12.10 64-bit for my graphics card (ATI Radeon HD 7570). I am using two displays, one connected with DVI, one with HDMI. I set the desktop to be expanded to both screens and disabled the under scan for the HDMI screen, which is always for some reason enabled on HDMI screens.

Now the issue. Everything was fine until I restarted my computer. After reboot, the screen connected with HDMI cable had the black borders again, meaning that the under scan is again enabled. I checked the ATI CCC, and under scan was disabled. However, moving the slider to enable under scan and then back to zero fixed the issue -- temporarily. The same issue is repeated every time I restart my computer. The settings remains the same, but the computer seems to ignore it.

Any ideas how I could solve the issue?
