I'm pretty darn certain it's probably TN, due to the 1ms quotation.HOWEVER........
A refresh cycle at 120Hz = 1/120 = 8.3 milliseconds. With a strobe backlight, you can bypass the vast majority of GtG under certain conditions. 1ms effective measured persistence an IPS/VA is actually theoretically possible with the following:
(1) Backlight strobes of 1ms each, on clean, fully refreshed frames.
(2) Aggressive pixel driving techniques to hide the remaining 7ms in total darkness. Basically, squeeze the remaining pixel transition (GtG from one color to another) completely into the 7ms dark period between backlight strobes.
(Example: high speed video of LightBoost
As long as you can squeeze the GtG into total darkness (backlight off), the GtG can be messy (unseen to human eyes) for a whole 7ms. What's matter is the LCD is done refreshing and clean, during the final 1ms, during the backlight strobe. You see, mathematically, backlight strobes can be shorter than GtG. Motion clarity becomes dictated by the length of backlight strobe (persistence).
Remnants of transitions need to remain well under 5% (e.g. less than 5% crosstalk between refreshes) in order for the motion clarity effect (of typical game material) to be clearly dominant. On several good TN panel, some transitions are so complete that transition inaccuracy by next refresh is below human vision noise floor (e.g. like the difference greyscale level 254 versus greyscale level 255). At this point, GtG totally, completely ceases to be the limiting factor in LCD motion clarity, and the length/brightness of the strobe becomes the motion clarity limiting factor.
VA just barely reached this stage (EIZO's FG2421, especially when warmed up
), but I'm not sure if IPS has reached this stage yet.
