120 Hz is meant for movies that are encoded at 24fps. When the TV then detects a 24 Hz signal it then displays the same frame 5 times(works for other framerates as well). It's also known as frame or motion interpolation.

Here's an interesting article about motion judder:

Interesting articles. I will have to get Casino Royale on BR to see this stuttering . . . Not calling anyone a liar but I'd like to see it. And if it's as bad as everyone is saying, I'll be stunned.

120 Hz ruins watching movies for me. It looks completely fake.

Yes, if you put TrueMotion or smoothing on it looks fake.

But leave that off and run the movies at 24p. That is if you're watching Blu-Rays.

I think I've seen this phenomenon before. It's like the movie is in fastforward but it's not. I hated it and wondered why anyone would pay so much to have a movie look like that. My hdtv's/projectors are all either 720p or 1080i and I still love the way the picture looks. They can keep the fastforward look.

My buddy had a 42" Vizio LCD @ 60hz (1080p), and recently exchanged it for a 55" Vizio LCD @ 120hz (1080p). The newer one everything just seems smoother. Be it gaming on his PC, his 360, watching a movie (HD or SD), or just watching tv. Over all framerate seems to be higher.

Could just be placebo, but since I didn't buy the tv nor do I care for it much- I doubt it is placebo.

best refresh rate for 23.976fps (aka 24p) material is 23.976hz (aka 24hz)

i hate 120hz screen for watching movies, makes me slighty dizzy.

You guys are getting 120hz and frame interpolation mixed up. They aren't the same thing.


Displaying a movie or anything at 120hz will not cause it to look "fake". You are thinking of frame interpolation. Again. Completely different thing all together. Look up Auto-Motion Plus . That's Samsung's version of frame interpolation. It basically creates frames between frames to make things appear "smooth". The end result is a clearer picture for moving objects, however its extremely distracting and "fake" looking. Not good for watching movies or anything really.

Again. 120hz does not = frame interpolation. Do some research.









BTW. I just bought a 60" Mitsubishi DLP. After spending 2-3 hours calibrating it, I can honestly say the picture is perfect.

Thanks for the clarification. I don't have many settings for the "AutoMotion" feature but I've turned it completely off. Blu-Rays look great on my Sony!
