Some LCDs run 75hz, but since there is no flicker issue on an LCD, there
is no real need for higher refresh rates than 60hz.  Higher refresh
rates take more bandwidth too, which is why 59 or 60hz is what is
normally used.  The maximum amount of pixels you can send through a
single link DVI connection is 1920x1200 at 60hz.  It can't do it at 75hz,
there simply isn't enough bandwidth.  Dual link can do twic that, so
hence 2560x1600 at 60hz on large displays, although some high resolution
displays do 3840x2400 at 24hz on dual link (48hz on quad link).
