Since the effect on the actual display is governed by how fast you can
show a new picture, it makes no difference if they aren't the same (and
I never claimed they were).

Apparently, you're not much on math. 1/60 of a second is 16.66ms. Most
LCDs take about 15ms complete the change from one color to another, so
it's close. Many LCDs take far *more* than 16ms (and thus far more than
1/60th of a second), just as I said.

LCDs that claim "8ms" don't have that speed for changing from an abitrary
color to another. Those ratings are usually for white-to-black or
black-to-white. LCDs in the real world take 15ms to switch colors.
