Once upon a time I had a brief correspondence with an nvidia support
guy who knew what he was talking about. He said that with the newer
cards (with tvout on-chip), some modeline resolutions cause the
binary driver to go into "non-scaling" mode. That at least reduces
one of the variables.
Tell us more! Which modelines?
Sorry to get your hopes up, but notice I said "brief
correspondence." When I emailed for more details I never heard back. As
near as I could tell, it wasn't "modelines," but rather "resolutions." As
anyone who's tweaked modelines can tell you, they're not the same thing.
One can constructe a 320x240 "resolution" from a 1600x1200 "modeline" and
get an impressively underscanned result that's different from what anyone
else would guess.
In any event, a "720x480" resolution would be the first one to
try. As I said, I haven't had an nvidia card with tvout that doesn't blow
goats, so I haven't tested it too much.
