Not being an expert in this area by any means, but having used LCS glasses 
for years, I can say that these numbers are in reference to the refresh rate 
of your monitor.

Most "cheapo" monitors run at a refresh rate of 60 mhz, some at 72mhz and 
that is one reason why extended computer use in front of those monitors can 
cause some eye strain. The higher the refresh rate, the less flicker there 
is - so - the more comfort there is. The image appears to be more "solid", 
and the difference is physically noticable by some users.

Looking at a screen with LCS glasses at 85 mhz will still present a flicker 
- OK for some, but far too annoying for me. 120mhz is the best option for 
JPS images as far as I am concerned - at 640x480 for that matter... WHY 
640x480 YOU ASK??? =) Simply because many people who DO have monitors that 
can display 120mhz images, can only do so at that lower resolution. Is that 
a problems for end image quality? No. The "viewer" program resets the 
resolution mode from 800x600 or 1024x768 or whatever to 640x480, shows you 
the image full screen, and when you are done, takes you back where you 
started. You still get an amazing, full screen image.

Enough for now... Any questions or comments?
