Samsung UN55D6400 price range: $1,094.00 - $1,749.95

The good: The Samsung UND6400 series offers beautiful, compact styling with an ultrathin bezel and panel for a nearly all-picture look. It produces relatively deep black levels for an edge-lit LED-based LCD TV, with accurate color in bright areas, excellent video processing, and improved 3D picture quality. The Smart Hub Internet portal boasts more apps and streaming services than the competition.
The bad: This Samsung LED TV is relatively expensive. Its picture suffers from imperfect screen uniformity and blue-tinged darker areas, while its glossy screen reflects a lot of ambient light. The UND6400's Smart Hub lacks Amazon Instant, its search is next to useless, and its interface can be cluttered and confusing.
The bottom line: Solid overall 2D and 3D picture quality, as well as a wealth of features and beautiful looks, mark the Samsung UND6400 as one of the better edge-lit LED-based LCD TVs we've tested.

Overall a Great T.V.
by DonaldMSmith on February 14, 2012
Pros: + Picture quality is excellent

+ Excellent Sound quality (for a t.v.)
+ Smart Hub has a lot of potential
+ T.V. settings menus are well laid out and easy to useCons: - I have noticed some flashlighting in the bottom left corner of the screen

Summary: I bought this t.v. to replace our 27" crt. I did a lot of looking before buying. I've had it a little over a week. I have not had a chance to try out the 3-D yet. It is a great "smart t.v." but with a few minor flaws.
My Samsung D6400 television is connected to a Samsung BDD6700 Blu-Ray player (excellent!) and an ethernet connection to the t.v. (not wireless) at 12 to 20 or so mgb.
Pros:
Design: This t.v. looks great in the living room. I was afraid it would overwhelm the room, but it doesn't. Glad I went with a 46" instead of a 40". Love the glossy screen. Reflections are not a problem and the lack of a matte finish I think enhances colors.
Sound quality: Excellent (for a t.v.). I was worried that it would sound completely awful (since the t.v. is so thin) and I can not afford an hdmi capable receiver at the moment. I'm glad I didn't let that keep me from buying the t.v. Keep in mind, though, that a few reviewers have noted a sound-sync problem when running the t.v. through an external audio unit. I have not done this yet.
Picture quality: The picture quality is excellent (but I have not tried out the 3-D yet). Blu-rays look great, dvds look great (after adjusting the automotion a bit), high-definition television looks great. Watching home photos and movies by attaching an external hard drive to the usb port is a lot of fun. Video quality from our point and shoot 720p camera looks great on this t.v.. This t.v. makes most Youtube videos look better than they look on my laptop. Picture sizing options are on the remote to maximize video quality depending on the source. The Wii looks fine on it even at full-screen. The quality of streaming movies from Netflix varies from very good to excellent, but any fault lies with Netflix, not Samsung.
Off-angle viewing: I've read some professional reviews that note "poor off-angle viewing" quality. We haven't noticed the picture degrading except at the most extreme of angles. We think the picture looks great from just about anywhere in the room.
Apps (Smart Hub): Smart Hub has a lot of potential, but it's not totally there yet. Some apps are outstanding (such as Vudu, Pandora, and Googlemaps). Other apps (such as Vimeo) definitely feel "half-baked." The Youtube app on the t.v. stinks. It automatically loads a video when you start the app. I can't figure out how to stop it from loading a random video. If you've got kids in the room random Youtube videos chosen by the app are NOT a good thing. On the other hand, the Youtube app on my Samsung bdd6700 Blu-Ray player is great. It does NOT load a random video on start-up. It just sits there nicely until I search for something or choose to play something.
Interface: The t.v. settings menus are well laid out and easy to use. App interfaces vary, but are generally very good to excellent.
Cons:
The backlight: This is an edge-lit led t.v. and has some of the problems that come with that technology. I have noticed some flashlighting in the bottom left corner of the screen. It is not there all of the time and it is not bad enough to return the t.v. or mess up the picture. Most of the time I don't notice it at all. Also, the backlight has uniformity problems when using some Smart Hub apps such as Youtube. This uniformity problem does not seem to be there when watching Blu-rays, dvds, or cable television. In the daytime or in a room with a light on it probably wouldn't be noticed. If you like to watch Youtube videos in the dark, it will probably drive you bonkers. This problem only seems to there when using some of the apps.
Bottom line: A great smart t.v. with a ton of capabilities and a great picture for the price. Sure the "backlight uniformity with some apps problem" is a disappointment, but this t.v. does such a great job with so many different input sources that I'm willing to cut Samsung some slack for that. Pair this t.v. with the Samsung BDD6700 Blu-Ray player. They "play well" together.

Edit URL
The picture is absolutely stunning. I upgraded from a 50' Samsung DLP that I'd had for about 7 years. I truly didn't realize what I was missing with the technology advancements of 1080P LCDs and LEDs over the last few years. My wife and I will be watching HDTV in either 1080i or 720p and look at each other and say this doesn't look like "normal" TV. We finally figured it out last night. The picture is so clear that television shows truly appear to us as if we're looking through a window into somebody's home or perhaps watching a live performance/sporting event. We can even start to decipher how "fake" some of the sets are that the producers are using on many of the sitcoms.
Watching a Blu-ray is almost like watching a video game. The frame rate and clarity are so much improved over previous generation sets that it really gives you a whole new movie-watching experience. Blu-rays might take some getting used to for me because they are so life-like that I tend to just stare in awe rather than paying attention to the movie.
The 3D function of the television also blew me away. I really wasn't sure what to expect here, but took a leap of faith because the price was so incredible. Not only does the 3D create depth when you are watching 3D blu-rays. The picture actually comes at you as if you were in the theater. So far the only experiences I've had with 3D are with a couple of the IMAX 3D blu-rays that I purchased on Amazon. The 2D to 3D function is a bit gimmicky. I've used it to watch baseball games and the NHL playoffs and it does add a little depth to the picture, but probably not enough difference for me to have to wear the glasses all the time.
The one knock against LED televisions has been black levels. While I do notice that the blacks are not quite as deep as other TVs, it really is overshadowed by the beauty and clarity of the rest of the picture.
*** P.S. If you will buy this TV I suggest you have compare price before you decide at: www.amazon.com/gp/*************?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%****%2Foffer-listing%2FB004NZBAF2%3Fie%3DUTF8%26ref_%3Ddp_olp_new_map%26condition%3Dnew%23&tag=***************&********=ur2&camp=1789&creative=390957

Great product. Picture quality 10++
by conhig1961 on January 8, 2012
Pros: Styling, picture quality, ease of setup and use.
Cons: A bit pricey, Wifi dongle not included. Would prefer remote not have so many look-alike buttons, but is backlit, so that helps.
Summary: I researched many products and after all the dust settled, the UN55D6420 was my choice. I have had it almost 1 week and am blown away at the quality of ...

Not worth it. Picture quality very poor.
by slimjim00 on November 29, 2011
Pros: Not worth your money. maybe spend euros on this but not dollars!
Cons: I was disapointed to find out that my Xbox 360 doesnt come through in HD. That my cable doesnt come through in HD. In fact the picture quality is so poor I shouldve bough an 1989 rear prejection TV instead. Bad picture. Lots of 'shutter'.
Summary: DONT BUY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
