Agreed - I saw a 200 Hz comparison with 50 Hz, the difference was amazing.

It's all needed because of the way LCD works, it "holds" the pixel colour on
the screen for the entire length of the frame, rather than the CRT way of
just providing a burst. This means that for moving images, whilst your eye
is tracking the motion, you see a blur rather than a smooth sharp movement.
This happens even if the response time is zero, but longer response times
just make matters worse.
You can either fix this problem by doubling up frame-rate or resolution -
both work equally well, and just need some algorithm to interpolate between
frames/pixels.
