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...

Samsung UN55D6400 55″ LED Smart TV Review


The Samsung UN55D6400 is a 55-Inch 3D LED HDTV that packs in a 1080p resolution, a 5,000,000:1 Dynamic Contrast Ratio, but more on all of that later. The ...

Lightweight, thin and sexy design, stunning visuals with vivid, life-like color and motion, Smart TV apps extend the functionality of your TV, energy efficient, catalog of apps is always growing

On the pricier side, QWERTY remote costs extra – as does the USB Wi-Fi adapter, search function is anemic, web browser is  not available in the 6000 or 7000 series

I Love My New TV


I received my 55 inch TV on time and in great condition. Set up was fast and easy. The picture looked great right out of the box. I did tweak the settings to my taste and for the room. I was worried it would be too large for my 15 by 15 foot living...

Great product


Picture is awesome, easy to setup and unpack. Only complaint, sound quality could be as lot better. Add a sound bar to solve the problem.Lots of features (3D if desired)and 4 HDMI ports give lots of life for additional equipment additions.
