>From what I understand, a TV capable of "120Hz" isn't capable of receiving a
120Hz signal.  It will only receive a 24Hz, 30Hz and 60Hz signal then
quintuple, quadruple, or double the frame rate to give you 120Hz.  TVs that
are capable of 240Hz AND are 3D are capable of receiving 120Hz material, as
the 3D signal needs that frame rate to do it's "3D-ness".  Again, I could be
wrong, but this is how I always understood it.
