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.
Review: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 remote--and flaunts a fetchingly thin bezel and minimal design aesthetic second only to its significantly more expensive linemates such as the

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 remote--and flaunts a fetchingly thin bezel and minimal design aesthetic second only to its significantly more expensive linemates such as the UND7000. Meanwhile, if you don't mind a thicker bezel and want to boycott 3D and save $100 in the process, the UND6300 series is one alternative. The D6400, for its part, is still pretty expensive, but justifies its high sticker price with solid picture quality, beating out most edge-lit LED models, including the equivalent Samsung from last year. It certainly has its flaws, but it occupies a sweet spot for LED and Internet TV shoppers who don't want to take out a second mortgage to pay for a flagship model.
Series information: We performed a hands-on evaluation of the 46-inch Samsung UN46D6400, but this review also applies to the other screen sizes in the series. All sizes have identical specs and according to the manufacturer should provide very similar picture quality. We also expect the company to announce the 32-inch UN32D6400, but at press time it hadn't yet, so we're not including it below.
