You want to adjust your modeline, which may be implicit, but can
be overriden in xorg.conf.

http://www.tkk.fi/Misc/Electronics/faq/vga2rgb/calc.html has a
modeline calculator.

On the other hand, it may be that the NVidia TVout completely
bypasses the modeline, in which case, you may be hosed without
the ability to change it on the TV itself.


Every time you give up a right, the terrorists win.
