Hmm, you dont actually need anything over 70Hz, as your eyes only refresh at 70, anything over that is overkill.
Tell that to my eyes, If I go below 85Hz I'll notice the flicker and get sore eyes, I can get used to it but I'll not be able to sit in front of the monitor for so long.
Weirdly If I go up to 90Hz I get uncomfortable again, 85Hz seems to be the sweet spot for me at least.
One advantage of LCDs does seem to be you can sit in front of them for longer.
BTW I wasn't aware human eyes did refresh - you a cyborg or something :-P
