No, they expand the amount you tell them to. Overscan is done with a 
single line in XF86Config, with an overscan value ranging from 0.0 to 
1.0.

I'm guessing your problem is that to fill out the entire screen, you're 
having to overscan quite a bit to compensate for one aspect, but it is 
too much for the other aspect. You might have different results with a 
different card. I've used 4 different GF4 Ti and GF4MX cards in my 
system at one time or another, and all varied a fair amount on the 
amount of overscan needed, and the image they output varied in exact 
on-screen dimensions, so some fit better than others. I'm quite happy 
with what I get using my current card (Chaintech GF4MX 440 8X, 64MB) 
and a 0.6 overscan value, and everything is accessible on-screen 
(window widgets, scroll bars, Kicker, etc).
