> That's crazy. 60 and 120 are night and day. Moving the cursor around at 60 feels like of like waving your hand under one of those LED lights that "invisibly" strobe to save energy.

Many people can't perceive that LED flicker either (or before that, fluorescent light flicker), while others can.

I'm a huge fan of the RTINGS monitor reviews, which measure backlight flicker and identify which monitors do and don't have it, because I can notice that flicker and it gives me a headache.
