Full HD 1080P

full HD 1080P Full HD, or 1080p, contains 1.5 times more scanning lines than conventional HD TVs. More scanning lines mean more pixels, more details and a better picture. The new Samsung LCD TV with resolution that is approximately 2 times greater than conventional HDTVs, creating the most perfect picture imaginable. Samsung's 1080p panel uses a new high-speed liquid crystal to cut response time to 6ms (milliseconds).

Auto Motion Plus 120Hz

auto motion plus 120Hz This technology doubles the frame rate from 60 to 120 frames per second (120Hz LCD panel) without repeating the same image to make more frames. Instead, the TV intelligently calculates the ‘middle' image between frame A and frame B and inserts it in between (Auto Motion Plus 120Hz processor), making a fluid transition from one frame to the next.

Wide Color Enhancer 2/Cold Cathode Fluorescent Lamp

Wide Color Enhancer 2 The NTSC (National Television Systems Committee) has established the color standards all TVs in America try to meet. And typical LCD TVs only meet about 72 percent of this standard. Samsung LCD HDTVs use Cold Cathode Fluorescent Lamp backlights to give you 92 percent coverage of the NTSC standard, ensuring truer, more breathlessly vivid colors.

Samsung's Wide Color Enhancer 3 technology delivers more brilliant colors by expanding the gamut of color expression into a third axis, creating a 3D diagram of luminance. This creates a dynamic display of on-screen color and allows traditionally weak colors, such as green and blue, to look vivid and deep. In addition, red colors are enhanced to provide strong colors across the spectrum and the perfect balance of RGB.

100,000:1 Dynamic Contrast Ratio

100,000:1 Dynamic Contrast Ratio 100,000:1 Dynamic Contrast Ratio will give you a picture better than you ever thought possible, with whiter whites, blacker blacks and a nearly infinite subtlety of gradations in between. As two of the most important determining factors in overall picture quality, contrast and brightness levels achieve new heights in this latest generation LCD panel. Samsung's new LCD TV's give the most stunning realistic picture quality ever.

Touch of Color

Touch of Color In 2008, Samsung created its unique Touch of Color (ToC) design, which uses dual-injection molding to coat a translucent, colored surface to achieve an attractive crystalline appearance. The latest evolution of Samsung's ToC design begins with a deep piano black bezel that fades into distinct chrome that finishes as light ruby highlights. The intensity of the color subtly changes depending upon the viewing angle, and further accentuates these TV's slim bezels.


Touch of Color Up-to-the-minute access to weather, news, sports and stock information is just a cable and a click away through the HDTV's Ethernet port and new InfoLink RSS service. An all-new user interface with digital contents management guide provides intuitive navigation and access to both internal and external content.

Which Size HDTV is Right for My Room?

HDTV Size chart
With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience.

If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get.

  • Minimum size = Viewing distance/3
  • Maximum size=Viewing distance/1.5

I'm happy to be the first to rate this wonderful LCD. I'll be short and to the point, and maybe come back and supplement this review after a few more weeks of use.

Aesthetically, the TV is clean and elegant. Love the touch of red. Love the crystal base. Love the fact that it swivels. It's a beautiful piece of equipment, and looks a good bit more modern than the more curvilinear A model. I'm very happy I waited for this one.

Set up was a snap. Took me about 2 minutes to connect the base. It took longer to remove the stickers. The manual is on a little USB drive that plugs in the side of the TV, but I haven't bothered with it yet.

The picture is stunning, right out of the box. Absolutely beautiful. Only adjustment I made was to turn the brightness down slightly, as I have a very dark TV room.

The on-screen graphics and menus are both intuitive and elegantly designed. I hate when the industrial design is carefully considered, and the on-screen UI is forgotten. That didn't happen here. Both are wonderful.

I somewhat skeptically connected my camera card reader to one of the USB plugs on the side, and inserted a memory card from my father's camera. He'd hoped to show us pictures, but didn't have a plan for how. Perfect timing, as the TV had arrived that day. The TV recognized the card, and very quickly we were watching pictures and video in high res on our new TV. Fantastic.

Less than perfect: the sound. Actually, it's a bit of joke. But, that doesn't effect my rating because I don't feel that the internal speakers are really meant to be used w/ a TV like this. I'm using a 5 channel surround system, but before I hooked it up, I heard the speakers. It makes sense that they wouldn't sound good since you can't even see them.

I returned the 40A630 that I bought last month because of one dead pixel, and I replaced it with this spanking new model (date first available at Amazon on March 9th). This LCD TV is really beautiful - the "Red Touch of Color" is not quite subtle but I'm sure you'll like it as much as I do (it will match whatever furniture you have). The picture quality of this model (100,000:1 contrast ratio) is quite stunning compared to the 40A630 (40,000:1) that I returned.

This TV offers the newly introduced Internet@TV. Currently, only Samsung B series has this feature, other manufacturers will incorporate this feature in their future models. This feature is better than the first generation Infolink (RSS feed) that's offered by the A series. You can actually add all sorts of TV widgets, which in the next couple of months will include some of the big online content providers (NY Times, Netflix, eBay, Twitter, Google, etc). Currenly, only Yahoo widgets are available (news, weather, Flickr, finance). You can connect your TV to the internet via ethernet, or you can plug Samsung's Wireless USB adaptor (sold separately) in one of the 2 USB ports.

Other notable features:
a) 2 USB 2.0 slots - I use one slot for the included flash drive which contains the TV manual, and the other slot for my 8GB flash containing pictures, music and video.
b) Content Library - Intenal flash with preloaded content like cooking recipes, artwork screensavers, games, and pre-school children contents. You can download more contents from the internet. I don't find this feature interesting. I tried it twice during the first week, and I haven't explored it again since.
c) Swivel base - I think Samsung is the only brand that offers this feature, which I find really useful.

I purchased this TV because of the GREAT reviews here at Amazon & other websites. Only 1 thing, and a warning to everyone considering this TV. After owning this for less than 10 months, it started powering on & off after being on for 3-4 hours. I spoke to Samsung Customer Service, was told to reset the TV, unplug it from the surge protector I was protecing it with & plug directly into an outlet. In less than 1 week the situation got worse, so that it performed its on-off routine in 1.5 hours of being on. I Googled the problem, and found out that many were complaining of the same issue, and that these TV's are fitted with a bad power supply. Thank goodness it was still under factory warranty, as the service people came & took it in to replace the power supply (which, by the way has taken more than 2 weeks).
It seems this problem has affected ALL Samsung LCD models, from 30" up to 50". The service guys actually told me to be sure I had an extended warranty, as even though Samsung has updated the power supply software, they could not assure me that this won't happen again.
In the meantime, I am stuck without my beautiful TV for the 3rd Sunday in a row without being able to watch football on the big secreen. What a bummer! We asked what brand TV do they have to service less--Sony! Too bad we didn't spring for a bit more money & buy that one.
Hopefully, this trip to the service people will solve the problem, but it's very worrisome that
a new TV would go bad in such a short time. From what I have read while researching the problem, a lot of folks had this happen to them after their 1 year manufacturer's warranty was already up.
