I don't think in this case it is purely the TV.  I can hook my DCT-6200 
cable box to the TV, and via the service menu in the TV move the image 
right and left and see that my overscan there is roughly 2" (on a 54" 
widescreen) on each side, and about 1" up and down.  With the GeForce 
6200 (annoying coincidence in model numbering) it is more like 5" on 
each side and 3" up and down.  Nothing is changed on the TV, and even 
the same cables are used.  That tells me that what the video card is 
putting out isn't the same as what is coming out of the cable box.  And 
of course, as mentioned, you can't change what is coming out via any 
known modeline or X setting.
