** SIGH **
The glasses will still operate at a maximum of 120Hz, alanh. This is necessary to minimise ghosting with current plasma and LED displays.
You need to go to a public cinema, or a very up-market and expensive home projector, to do better than a 120Hz alternation rate.
And I am not talking about the precision of the duty cycle (which is typically much higher than 120Hz). I am talking about the actual alternation rate between Left and Right.
Please do not bring anything that resembles actual facts into any discussion involving Alanhasnof-ingidea - they only confuse him more.
