Basically, 2ms you need 500hz refresh rate screen. 5ms required 200hz. So, do you think 120hz is fast enough to show the different? Think again.
When buying LCD, what you should be aware of is it's display lag/delay not respond time. As long as it is anything above 8ms, there shouldn't be any different.
GTG rating being adverstised does not correlate with refresh rate that way.
2ms or 5ms
GTG hardly qualifies for a full pixel twist and back (which is roughly 2x the GTG rating).. Only TN with 2ms GTG (and roughly @ 5ms BTWTB) is sufficiently fast enough for a true 120Hz, a requirement for nvidia's 3d in which each eye is blocked 60 x/s (60Hz) intermittently.
A 5ms GTG panel with roughly 10ms BTWTB full pixel twisting is not fast enough at 120Hz.
Delay ... it is the time required for the monitor to process the signal before output... say compared to a CRT.
Both CRTs and LCDs have delays.. but even the best quality LCD may have an average 20 to 30ms longer delay than CRTs. The fastest panels (without much processing) may have an average delay in the teens ms (exp: 10 to 15ms), at times the delay is even at 0ms.
