There's also a 24p mode in players as well as TV's. But playing back a video at 24 FPS without duplicating frames is going to be unwatchable. 24 FPS + (theoretical) 24 Hz you're saying?
Not quite. Basically, a 60 Hz monitor cannot playback at 24hz without issue, as you said. This is where progressive scan comes in. What it essentially does is reverse the process of 3-2 pulldown by scanning the frames ahead and correcting any artifacts left by the 3-2 pulldown process. What you get is essentially 24 Hz video being played at 30 Hz without an pulldown artifacts. Of course, this can still leave judder but progressive scan has been around for awhile and has become very good at what it does.
almost forgot source.
