24HZ vs. 120 HZ?

[Pelican170]

Ok, now if this is a stupid question, i apologize. Ive been researching the different outputs and just a little confused i guess. So, my brother got a new samsung LCD, it can accept 24 hz, i checked it out last night, seemed very nice and didnt notice any jutters. Now, with the 120 hz that some sets offer, would this be a better setting due to a smoother picture from motion? Is that the only difference?

120HZ originally had nothing to do with 24p, they were meant to make 60i look smoother. Modern PAL TVs have 100HZ (to smooth out 50i) Though newer NTSC sets with 120HZ do a 5:5 pulldown on 24 frames, I am not sure if this makes 24p look better though.

it doesn't matter it the LCD can ACCEPT 24hz (and then run a 3:2 pulldown), it matters is the tv can DISPLAY 24hz, there is a big difference.

Like I said before, I believe your brother has a 6 series, which are all 60hz HDTVs, besides the 69. These TVs accept a 24hz singnal and will do a 3:2 pulldown and you will get UNEVEN judder (though the 6 series does a great job at minimizing this). 24fps film has JUDDER in it. a 60hz HDTV produces UNEVEN judder and that is the big issue between 60hz and 24hz.

A 120hz TV will use interpolation (w/motion enhancers on) which will make the picture very smooth, but I and many other HT enthusisits, do not believe this is the way the movie was meant to look.

A 120hz TV without motion enhances on will simply show the same frame 5 times 24fps (5x24 = 120). You will still have EVEN judder in this, but EVEN judder is a part of film. I don't think you are seeing any judder because thats what your eyes are used to.

I honestly don't see much of a difference between a 6 series HDTV and a 120hz HDTV w/motion enhancers off, to warrent a new purchase.

There is a thread over at AVS if you can find it specifically about these HDTVs and 24hz v 60hz.

No, you aren't. My HDTV says the exact same thing. Its simply saying that the signal being fed into the TV is 24hz. The TV is still converting it to 60hz, because thats all those TVs can display.

Its very confusing, I had a very similar situation to what you are having now. and after doing quite a bit of research came to the conclusion that these TVs can accept in a 24hz signal, however cannot display 24hz and have to use a 3:2 pulldown.

The 6 series samsungs are beautiful HDTVs to say the least and your brother made a very good choice.

OK im understanding more and more what you are saying. THanks again for the info.

I have a Sony KDL-40v3000 and it accepts a 24 fps input and it does help smooth out the movie. I agree that 120 Hz makes movies look very odd and I truly dislike it. It makes the movie appear as if it's being played at an increased rate. They say that this is because it is more life like movement, but as far as I have compared (as I am an empiricist) real life doesn't look like that...
