Well the Hz is supposed to be a measure of the refresh rate of the screen. With LCD's you can adjust how much of the enhanced motion is actually seen and to what degree. Samsung have a setting that is called the auto motion plus, and you adjust it depending on your preference.
The plasmas that now say 600Hz there is no way to adjust motion viewing on them, besides plasmas never have had an issue with motion. And your cable box probably says that because it is the signal it is sending out, so changing settings on your TV isn't going to change what the cable box is capable of doing.
I hope this answers some of the question about it.

So, what's the idea when they say "600Hz Subfield Motion Technology"?
Little sucks that i can only view in 60Hz.
So, does 600Hz Subfield Motion Technology automatically adjust up to 120 Hz?
What are some contents that I can see some improvement?

600 Hz = marketing mumbojumbo made to make the TV look better than other manufacturers when in reality it isn't.
The only possible benefit of a 600 Hz refresh rate is to perform temporal dithering - Getting greater bit depth (color accuracy) by rapidly moving a pixel between two brightness values, the eye would see the average of these values.
Whether a 600 Hz plasma actually has this benefit, I do not know.

All this Hertz madness has me laughing.
My 720P 60hz Pioneer plasma still gives me chills.

While it's true Marketing has something to do with it (most people automatically assume the higher the Hz the better the motion artifacting), it isn't complete BS. It is not the same as the Hz rating on an LCD. Plasmas such as Panasonic are divided into 10 subfields, each subfield receiving a 60hz processing. 10x60= 600hz. But the actual refresh rate of the pixels on modern plasma panels is .001 milliseconds. Yes, one microsecond. LCD panels typically claim 4ms, 3ms, 6ms, etc. [ms being millisecond]. As a result, Plasma has (and always has had) better motion than any LCD or LED regardless of the Hz rating. As far as 60Hz vs 120Hz, since virtually nothing outputs 120Hz, and ignoring the video processing (basically upconversion) onboard the television itself, 120Hz is easier divided into by 24fps (which most film is actually recorded in) than 60Hz (some TVs like Samsung offer a 96Hz "Cinema" mode as a result of the 24fps standard). Hence the smoother processing. No matter what, your TV has to change the image (process it) before it is displayed on screen. The better the processor, the better the picture. This is why Samsung will have 8 different 40" models that differ in price by as much as $600-1000: better processing. There is not a single spec on sales tags or even the instruction manuals that will tell you how good the processor is. You just have to look at the sets or get way in depth in tech review pages (for example, how many average consumers know what "DCDI by Faroudja" is, found in Onkyo and Denon receivers for video processing). Just read reviews, go to CNET, and watch the TVs in person before you buy one. Stop looking at Specs (a good example is Contrast Ratio, which is virtually arbitrary). Buy what looks good to you. Then have it professionally ISF calibrated.
Hope that helps
