Oh well, maybe i read it wrong and thought 120hz panel= Tru motion in the past like for my old LCD TV.
Taken from rtings:
The TV uses PWM to dim the backlight, but only below 17/100 backlight setting. Backlight PWM dimming results in a 120Hz flicker which might bother some people. This is very different behavior than the TCL
S405, which used PWM dimming throughout the entire range of its backlight levels
Not sure if they were talking tru motion like, things might have change, not sure. Perhars i read it wrong, not perfectly understanding what they ment.
