Yeah, depending on the model of Nvidia card you have, there may be a
setting on the "Nvidia Settings" GUI (can't remember the proper name) to
adjust this value. Look for anything related to overscan. The bad news
is, if it's not there, I don't think that particular version supports it
- in other words you're stuck with it. I run MythTV (well Mythbuntu) at
home on a TV and I have overscan, and an Nvidia card that doesn't allow
me to adjust overscan. So I use MythTV's custom settings to set the size
of the GUI to fit the screen.

Cheers, Tom
