It's 400Hz 'CMR' or Clear Motion Rate. I think that it's a 400Hz 'perceived' rate obtained thru image processing, and a 200Hz 'real', 'physical' refresh rate. I would love to have some info about this from someone who knows about this measuring standard, which is a marketing ploy, of course.
In 3D that mean 100 'real' Hz per eye which should be enough, but, oddly enough, it doesn't always feel so.
When playing Xbox 360 thru HDMI I use Standard image settings and a backlight level of 14, which I feel is ok, but most of the 'cloud spots' are still visible even with a backlight level of 4. Clouding is a variable issue with these TVs, so you might get lucky and get a better one.
I'll try to summarise the pros and cons.
- Image quality is very good, even when being upscaled from standard definition, blacks look great
- 200Hz, should be enough for anything
- It is very configurable, it has a crap ton of image settings you can fiddle with
- It's a smart TV, you have apps for YouTube, you can stream movies and images from your PC (although using Samsung AllShare isn't great, it crashes sometimes and it's a bit slow on the PC side)
- I use it mainly to play on my consoles, the response time is great, i'd say it's a very good TV for gaming
- for such a slim TV, sound is also good, and quite powerful
- for analog sources it has a noise image filter, i use it with digital TV, so I don't know how well that works, but it's there
- it looks pretty, white is not such a common color for a TV, and blends nicely against a white wall
- i have to double check, but I remember it has a picture-in-picture feature, you can watch a source like HDMI and have a small window with output from the normal TV source
- 3D is nice, nice glasses too, 2 pairs in the package
- has high speed n-standard WIFI, it's really fast, I was amazed it could stream 1080p content from my PC without problems
- F*ing clouding, good luck with that
- Expensive in my country, the google currency converter gives me 1024 pounds, 1275 euros or 1611 US dollars
- Very simple physical controls on the TV, just a 4 directions joystick on the back side which can turn on the TV and control sound volume and channel (i think it can get you in the menus as well, not sure though)
- for Scart and CI it has adapters, probably they could not fit the required connectors on the TV unit in order to keep it so slim, so they used some custom connectors and it comes with adapters for each
- the stand doesn't look so stable
