Kill overscan for ATI drivers?

I have a dual-boot Windows 7 64 bit/Linux 64 bit machine that uses ATI's Catalyst drivers. Sometimes I attach it to a 1080p LCD TV over HDMI. ATI is daft enough to provide a border to account for overscan.

"Sometimes Catalyst Control Center will not diplay the Overscan slider.

I have a VAIO laptop, and Sony uses its own ATI drivers, so no help from ATI's webpages. On that, I could not for the life of me find the overscan slider - whenever I chose to configure my display, it'd go directly to the Welcome Screen. This was after fiddling about with getting the stupid CCC to install in the first place (using ATI Mobility Modder).

Google searches told me, that a lot of users have this problem, not only on VAIO computers. Some have the overscan slider for a while, then it disappears, others like me never have it in the first place.

I did find a solution though:

Open regedit and go to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\

In there, there'll be some keys looking like this:

{ECA904C2-25E6-4680-9B2C-44EBC0EC9190} (with different numbers ;o)

Highlight the ""Video"" key on top of the tree, and do a search for ""1920x1080""

You'll find some keys in subfolders named 0000, 0001, etc.

The keys will begin with DALR6 DFPXXXXxYYYYx0xFF

XXXX= Horizontal resolution
YYYY= Vertical resolution
FF= Display frequency

Before you continue, take a bakup of the original keys by right-clicking the {ECA904C2-25E6-4680-9B2C-44EBC0EC9190}-type key, and select ""Export""

Click on the key matching the screen resolution and frequency you want to remove the borders of.

A lot of the key will consist of ""00"", but there'll be a few non-00 entries. Change all of these to 00.

Finally, I had two subfolders, 0000 and 0001, containing mirrors of the same keys. When I changed a key in one subfolder, it also changed in the other.

This fixed the problem for me, no need to install CCC.

Effects will take place next time you change the screen resolution.
