Both the 6-Series and 7-Series have 120Hz. 3:2 pulldown only fixes odd-even issues, such as 24 frames per second to 60frames per second, which of course, divides unevenly.
The benefit of 120Hz is that 3:2 pulldown is unnecessary. 24Hz, 30Hz, and 60Hz all divide evenly into the 120Hz ability of the television. This eliminates the need for 3:2 pulldown, which actually takes away from the 24fps film look you?re looking for.
If you?re going to watch a 24fps movie, then the 120Hz with AutoMotion Plus off will simply display each of the 24fps 5 frames at a time. This eliminates converging half-cells and processing. So it can do what you?re looking for it to do.
That said, many people see the benefit of AutoMotion Plus, which can take a 24fps picture and make the motion smoother in fast motion. But it?s defeatable ? that is, totally up to how you do your settings.
Hope that helps!
I've noticed that even though the series 6 (LN40A650) does have 120hz it doesn't have 3:2 pulldown. Then what happens when you turn off the 120hz? I've heard that a lot of people turn off 120hz when watching film, because 120hz makes film stop looking like 24fps. I think watching a movie in anything besides 24fps would bother me a lot, so obviously I'm not gonna buy a TV that automatically makes film look like video. So how does this work on series 6? I know that series 7 has both the pulldown and 120hz, which is completely safe, but 7 is quite a bit more expensive than 6. So I'm kinda stuck here until I get an answer to this problem.
