I think starting X with logverbose 5 tells you what EDID modes it gets
from the TV.  Anyway, specifying VertRefresh as I said will ensure
others are ignored.

It allows for precise timing of the vertical refresh.  It's much better
than trying to use the other methods, although people have reported
issues with the nvidia drivers which haven't affected me.

Not necessary really for standard def TV.  I don't use it.

That's one of the issues with the nvidia drivers, so try it and see.

I personally use kerneldeint as the OSD jitter is very annoying for me.
