Yep, it behaves very randomly, across the same GPU on different boards
even.

Overscan is very poorly supported on GPUs prior to the GF4, it depends
entirely on what off-chip TV encoder you have. Some will work, some
won't.

For your GF2, I would suggest ignoring all the nvidia options, and
looking at nvtv. It may work better, or it may break everything. I had
the latter a lot on my GF3 Ti 200, but then the nvidia drivers magically
did the right thing with it's off-chip TV encoder eventually :)

On GPUs from GF4 onwards, the support is also quite variable, but gets
better the newer you get. My FX5200 does "okay", tho the TV-out quality
is not the best, but it overscans the way I want it to.
