Samsung UN55D6400


Samsung's UND6400 occupies an upper-middle-class station in the company's extensive LED-based LCD lineup for 2011. It's the least expensive model to deliver 3D, gets the full Smart TV suite of Internet options--except for the browser and QWERTY...

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...

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...

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.

Samsung UN55D6400 Review – 55-inch LED LCD HDTV


In comparison to the advanced 3D and built in Wi-Fi enabled LED TV sets previewed by Samsung, this model looks a bit inferior. It comes with full 3D, HD and 1080p resolution and much better connectivity options to access your offline library of movies,...

The manufacturer has further included the Smart TV feature to access the online content and apps offered by a number of popular content providers and social networks. But the model does not come with built in Wi-Fi to offer a smart and efficient...

"Overall a Great T.V."


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.

+ Picture quality is excellent

- I have noticed some flashlighting in the bottom left corner of the screen

"Great product. Picture quality 10++"


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 this TV... Can't beat it!

Styling, picture quality, ease of setup and use.

A bit pricey, Wifi dongle not included. Would prefer remote not have so many look-alike buttons, but is backlit, so that helps.

"Not worth it. Picture quality very poor."



Not worth your money. maybe spend euros on this but not dollars!

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'.
