This is, of course, not true. Every one of these systems scan each pixel
in sequence *just* like a CRT. Do some research. Plasmas have the same
sort of phosphor decay issues that CRTs have.

And, other displays that can't scan and update each pixel fast enough
(like an LCD with 25ms "black-to-black" time that is trying to display
60p), you end up with smearing, tearing, and/or flicker.

Really? So, just what LCD, plasma, or LCoS display do you have that
accepts 24p as input and displays it as 24p so you can verify the
accuracy of your wild claim. Oh, yeah, you don't have one, because
nobody makes one.
