If I'm thinking clearly, nVidia cards, when outputting via svid,
composite, or component, take whatever resolution (and by extension,
modeline) you feed it, and shove it through a tv output encoder chip
that sanitizes it for the specific output type. The knob in
nvidia-settings twiddles the tv out encoder.
