The very first thing to do is to check your X logs
(/var/log/Xorg.0.log or /var/log/XFree86.0.log) and see what the
NVidia drivers are telling you. They will give full account of what
video modes they've detected, and why they've rejected others.

Once you've done that, you can take a look at your modelines and see
what they say.

That's a good place to start, anyways.
