Default Re: 60 Hz vs 120 Hz

The purpose of having a 120hz LCD screen is so that when an inverse telecine is done, the framerate can scale evenly between the player and the screen regardless of whether the film is 24fps or 30fps. It has nothing to do with "flickering" in the classical sense with CRT's. Specifically, 24x5=120, and 30x4=120. However the timing isn't as clean with rendering 24fps on a 60hz screen, and occasionally you may notice a slight jerkiness as a result of some frames being displayed for longer periods than other frames while e.g. the camera is panning over a distance.
