120Hz 3D IS 120Hz video processing. The TV internally processes the video signal at 120 Hz. One of the (main) reasons for this is to allow 3D support. It generates 2 images at 60Hz that the glasses sync up with and allow your right and left eye to perceive a 3D image. Another cool, similar thing that has been demonstrated with it, is to allow two wearers of the glasses to see 2 different (2D) pictures at 60Hz. One wearer sees one image, the other user gets a totally different image. Cool for gaming and stuff.
So the 120Hz internal video processing is used for multiple
things. One of the things that many people (but not you) come to this forum and ask or are confused about, is if this does the same sort of motion enhancement tricks that 120Hz LCD's do. It does not, and that's why many people here keep bringing this up, even though you haven't mentioned LCD's.
I respect Chris B., but respectfully disagree with what the Samsung tech told him. I know one of the primary
reasons for doing 120Hz processing is 3D, but it is not the only
I do not know how the Samsung internally handles the 24fps signal. It could be that the software inside it for some reason processes the 24fps video signal at 60Hz or something else. I don't know why they would do that, since they have the capacity to do 120Hz image processing. Anyways, like you I just know that the results on Blu Rays are great, however they are doing it.
I don't know what they do inside. I doubt most techs that you ask, (even if they purport to know), know what it does inside. Only the engineers and software coders really know, and I'm sure it's probably a protected bit of info by Samsung.
I don't think you are going to get any more real information about it, just more speculation, guesses, and 3rd hand information. Samsung claims 120Hz processing. One of the things they use it for is 3D. This TV displays 24fps blu ray material very smoothly. That's about all that can really be said on the matter

I did not claim anything. I responded to post over at the blu-ray section, and voila! Chris B. said no no it's not true. Since that was a blu-ray section, they might be bias on their answer/opinion so I came back here to find out. Here is the beginning of the thread: http://www.avsforum.com/avs-vb/showp...&postcount=819
Chris B. said specifically that 120Hz of 61A750 is there for 3D Support only. While I look at the FAQS here; mike_pro listed: it does 120Hz video processing, and displays smooth, judder free playback of 24fps material
. Note: Chris B. wrote that article. And he was responding at the blu-ray section saying the FAQS here is definitely incorrect. His credential was that he spoke to the Samsung techies; not some PR guys.
120Hz video processing and 120Hz 3D are two different things. So I'm here to find out the truth.
