how does the 120hz feature work?

It interpolates frames, were a normal panel will display at 60hz. Any 120hz tv will basically take the 60hz signal and double the frames.

Clear scan 120 Hz doubles the panel's 60 Hz refresh rate for clearer fast motion

I think that what goes in goes out as I don't any thing that supports 120 Hz. Use the audio out tofeed a big sound system for movies since Blueray players don't have audio output.

It does pass through a 3DVision signal, which requires 120Hz. Not sure about anything above that.

It is both. The TV has software that convert the 120Hz to 240Hz when the TV is ON. Thanks

It's 60hz. There is no LCD TV on the market that will display material from a 120hz input signal (e.g., some computer video cards). However, there are some LCDs that will take a 24/30/60hz signal and up-convert it to 120hz. Samsung's model is the LNT-5271F.

this is from cnet"The big step-up feature for this series is a 120Hz refresh rate, which is said to cut down on the motion blur sometimes seen by sharp-eyed viewers in fast-moving scenes -- although in our tests of 60Hz LCDs, motion blur hasn't been an issue."

I don't believe what they're talking about is broadcast signal. The difference between 60 and 120 Hz in the LCD world is the refresh rate speed of the TV processor. In other words at 60 Hz fast moving charactors get grainy and then smooth again when they stop. At 120 Hz this does not happen. In my opinion it is worth the extra cost because your not actually getting the true HD experience when fast moving objects fuzz out during movement. You can actually get this 120 Hz option for about 600 more dollars and it's well worth it if you can afford it. Unfortunately, I didn't have the luxury of knowing this bit of important information before I purchased my TV and now regretting it. I don't believe what they're talking about is broadcast signal.

No clue. I bought the 46" version and it is 60Hz only. The 55" apparently is 120Hz, at least according to the specs. I doubt the refresh rate is selectable

What the heck I purchased because one of my criteria was that it have a 120Hz. If it is 60 then that is totally false advertisement n I will investigate. I have always had superb experience w amazon so this is a concern.

No plasma TV's have "120Hz Technology". It is not needed for Plasma, as they don't have the motion jerkiness problem the LCDs have. 120Hz is an LCD only technology. 120Hz is for LCD tv's because of the latent shutter speed to turn an LCD pixel on or off. This is actually the inverse of the frequency, or .0083 seconds; which is the switch time for the crystal (This is not to be confused with response time or fps; both of which are also different performance metrics). The crystals turn on and off to allow light to pass through or block it for dim/dark scenes; or to turn a color on or off. A pixel in a plasma TV is actually a tiny one-pixel "tube" TV. Tube TVs have never had a problem with action smear or latency. Plasma pixels have a near instantaneous on/off time, so implementation of 120Hz technology not only does not apply, it is not needed. The pixels have no latency; you'll never see a 8ms or 6ms response time attributed to plasma TVs, because the "pixels" go on and off as they are energized or de-energized; with no latency (At least not humanly perceptible).

That depends... If you are playing something at 1080p 30hz the U-Vision adapter will upscale it to 2160p (4k) 30hz. If you are playing something that is over 30hz you will get an output of 1080p at the same refresh rate as whatever you are playing whether it's 60hz or 120hz. But the converter will give you expanded color depth and some better details. I'm assuming you are using hz and fps interchangeably for the answer above. If not, see below... The screen of the TV itself will always refresh at 120hz no matter the input, what you are limited by is the image processor and hdmi cables bandwidth. If you are displaying something that is 30 frames per second on a TV that refreshes at 120hz each frame of video will be displayed for 4 of the TV frames. If you are watching something that is 60 fps it will show up for 2 of the TV frames. The only way to send a true 120fps signal to a TV is to do so from a computer as far as I know. Tvs that have motion smoothing will interpolate (make up) a frame that is partway between the actual frames that the video source is putting out so that the motion appears smoother. This TV (depending on what firmware you have) does do this. The only downside is that you ha e to access the manufacturer service menu to enable or disable it.

You are say the 5271 does not have "true" 120Hz technology. What does that mean?Does the new A650 have "true" 120Hz technology or do I have to get a different brand?

This is not a 120hz TV, it is a 60HZ TV that has a feature called "120Hz Clear Motion" That means it is simulating higher rate (simulated 120Hz, NOT actual 120Hz) by inserting extra frames but the truel rate is 60Hz.

The 120Hz is simply the refresh rate of the TV. You are unable to turn it off as the tv will always refresh at that speed. The feature that may cause eye strain and which many people do not like is the Amp. It is merely an amplification of the picture that is performed at 120Hz by interpolating extra frames. It has the effect of making the picture look much more lifelike and fluid, which most people aren't used to at all. We are used to very low frame rates. The 120Hz is highly desirable if you are going to be watching any amount of movies on the screen because it allows for even temporal distribution of frames. At 60Hz, some frames will be displayed more times than other frames every second which causes a distortion of the picture, especially noticeable during pans or camera movements. At 120Hz, the frames are all displayed evenly across time.

Let me put it this way....Electricity in the USA is 60Hz. When you turn a light on, it actually has a flickering power. DO you see light bulbs flickering on and off? OF course not. The human eye see's 60Hz as "always on". So then what does 120Hz do? It may clear up video a little, but nothing more, and your results may vary. (Everyone's eyes are different). So enter 240 Hz. .... YOU CAN NOT SEE ANY DIFFERENCE FROM 120 TO 240hz. Period. It is so far beyond the human visual capacity its not funny. So 240 Hz is a MARKETING GIMMIC to charge you more.

The Samsung that I purchased has the 120HZ refresh rate. I can take a picture of the box that it was shipped in if you like.
