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 3/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.

80,000:1 Dynamic Contrast Ratio

70,000:1 Dynamic Contrast Ratio 80,000:1 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.

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

By S. Gibb on June 2, 2009
I recently purchased this item locally but am so impressed by the TV that I felt I should post my impression for others trying to decide where to spend their hard earned money, especially these days.

First, I would recommend that you to your local electronics store and look around and see which sets grab your attention as what is best to my eyes may not work for you. In my case I was somewhat limited in selection since the TV must fit into a TV cabinet that we own, so 40" was my absolute max. This criteria limited me to Sony, Samsung, and Vizio (in order of price point). A local warehouse club had the Vizio and a comparable Samsung (ln40b610 vs. ln40b630) for side by side comparison, and simply put there was no comparison what-so-ever. The Samsung wins hands down in terms of picture clarity, overall brightness, and contrast. The 80,000:1 contrast on this TV really shines. The Samsung to Sony comparison was a bit tighter as both units offered incredible picture quality and features but again the contrast ratio on the Samsung just made everything appear more pleasing to my eye. Given this, we purchased the Samsung and haven't looked back. Every time my wife and I watch a Blu-ray movie we are even more impressed with the picture quality! Seriously, this is a great TV at any price. The only TV I looked at that had better contrast was the Samsung LED (3,000,000:1) model but the price difference was just too much to justify.

I do have to agree with other reviewers regarding the "Auto Motion" settings producing images that are almost surreal. I have found that setting this on the middle setting produces the best results for me, but I have not played much with the custom adjustment mode yet, so I will hold off on a final review until I have had more time to tweak.

My old RCA 27" tube finally died, so it was time to enter into the world of HDTV's. After a ton of research and price hunting, I settled in on this 40" model for the full 1080, 120hZ experience (plus a smokin' deal from Amazon helped seal the deal).

First one arrived shattered, so that was a bit of a buzz kill. Fortunately the delivery includes set up & power up, so we immediately saw that the thing was destroyed. The delivery crew took it back with them and Amazon got another one out. The 2nd one arrived in perfect condition, and after getting DirecTV out to install the HD dish, I've been on HD for about a week now. I know this is not part of the product review, but Amazon's customer service was excellent in this matter.

All I can say is that the picture is more than I anticipated, having never owned an HDTV before. The clarity is unreal, the colors and images just pop off the screen.

Sports and movies are incredible to watch. I do see how some folks are a bit taken aback by how crisp movies appear (as if in 3d), and they have to get used to the look of cinema based stuff. It doesn't really bother me that much, as I know that's the byproduct of HD. It's crisp. It's clear. But I set the 120Hz option to standard, and I find that works well enough for my eyes. There are certain scenes in some movies that just look surreal, but not in a bad way (at least to me).

The amount of control that this TV gives you to adjust the picture is great -- you can stick with one of their built in "modes" (dynamic, standard, natural or movie) and then customize every aspect of the picture as much as you wish. I spent a couple of days just playing with the settings & calibrating. The dynamic mode is way too bright, and gives results that are just not natural.

Delivery was great. Arrived on time and set up the TV for me.

I couln't get the HDMI ports to work. Had the cable company come. They tried three HD boxes and two HDMI cables. Said the problem was the TV.

I called Samsung. They arranged for a new board to be shipped and arranged a repair time. The repair person had the same problem after he replaced the board. No HDMI ports worked. Said that they would have to send a new main board. After the next board was installed, they decided that the TV was not repairable. They gave me a number to call at Samsung to arrange a replacement.

Samsung did not have the same TV available. They said I could get a lesser model in exchange. If I want at least all the options I had before I would have to pay an additional $198.00. This is ridiculous.

I couldn't decide between a plasma and an LCD, so I bought both (with the intention of returning one) and set them up side by side, my cable hookup going to both. The plasma was a Panasonic TC-P42S1, the LCD was a Samsung LN40B630. I did my comparison channel-by-channel with lots of different programming, ranging from talk shows to cartoons to action movies to football games, in both high def and standard def.

Both are very good 40-42 inch TVs, in my opinion. Once I had adjusted the settings to my liking, I was hard-pressed to say that one looked notably better or worse than the other, though each had its strengths and weaknesses.

The Panasonic plasma had slightly more vibrant colors than the Samsung LCD. Blacks were noticably blacker and dark blues and purples looked deeper. The off-angle viewing was fantastic on the plasma, too. With the LCD, a smidge of color was lost when you shifted from 0 to 45 degrees. From deeper side angles, the picture was still watchable, but definitely shifted towards gray.

However, the Samsung LCD had a brighter, crisper image. In a dark room, details stood out better, and any programming that wasn't dark looked a little sharper. During the day, with the sun shining in, the LCD's image held up a bit better, too.

Motion is supposedly better on plasmas, but I couldn't really tell when comparing to a 120Hz LCD. Both TVs did equally well with typical television, and what blurs I saw seemed to be in the source material. I watched a football game for a while, but if the plasma gave a better viewing experience, it wasn't terribly obvious to me. Then again, I'm not a big sports fan, so maybe my eye isn't discerning enough.
