I have a brand new HP desktop PC with the AMD Radeon HD 7900 Series card installed that is running window7. It is connected to a Samsung SyncMaster SA350 monitor that has the most current drivers loaded.
With just the native drivers for this video card installed when I reboot the computer the desktop image fills the screen properly both during boot and after it is completely booted.
However after I downloaded and installed the most current drivers and Catalyst Control Center 12.6 this behavior changed.
Now when it is booting the desktop image does not fit the screen. It is condenced and there are about 1 inch black boarders around it. Once the computer is fully booted then it enlarges to fit the screen.
If I play around with the scaling option it appears that what is happening is that catalyst is forcing the display scaling to the default value of 8% while it is booting, then once it is fully booted it actually sets the display to the correct setting of 0% which is when it fills the screen.
I have tried everything that I can possibly think of to fix this issue so that it stays full screen both during boot and after fully booted with no luck.
Based on this behavior and all the other issues I have read about the scaling options, I think there is much work to be done here to correct these behaviors. Once it is set to 0%, it should not be chaning to 8% during boot time then back to 0 once booted.
If I perform an express remove of the AMD software the system then functions normally at full screen both during boot and after fully booted.
Reinstall Catalyst and the issue comes back.
I hope AMD can solve this issue.
I was going to report this on AMD's web site but both their "Contact Us" and "AMD Issue Reporting Form" is broken giving "Connect to upstream server failed" messages.
