The Sony KDL-55NX810 is a 55-inch LED 3D TV that has some really great features and backs it up with some solid performance too. Built-in Wi-Fi and Internet video capabilities all come without requiring you to shell out too much because Sony makes this TV well worth the money.
The KDL-55NX810 has a very thin black bezel that surrounds the screen and has an aesthetic of a high-end classy display. In total, it measures 50.3 x 1.4 x 30.4-inches (wdh) and weighs just short of 60 pounds. The unit sits atop a very thin and low-profile stand which makes it again, look quite stylish. When viewed from the side, the 1.4-inch thick screen looks almost futuristic. The stand allows for a whole lot of tilt adjustment.
The 55-inch display has a resolution of 1920 x 1080-pixels and is 1080p full high-definition resolution. Sony did make the screen quite glossy, which can pose a problem if you use the screen in a room that has sunlight or lots of lighting. This model should really be used in a room with zero to minimal ambient lighting for best quality. The horizontal and vertical viewing angles with this model are virtually 180 degrees, so that's another great plus. The LED screen is lit from the edges, which is different from the typical backlighting design. Sony also included a lighting sensor to automatically adjust the brightness and contrast levels depending upon the room's lighting. The MotionFlow technology inside the display also works to lessen motion blur and it really does a good job too.
Sony's KDL-55NX810 is also 3D capable, which means that you can get a 3D picture when you feed 3D content to the TV set, either via a 3D Blu-ray player or a compatible set-top cable/satellite box. As with other 3D HDTVs, you have to use the Sony active shutter glasses in order to "see" the 3D picture, but regular, 2D, TV can be viewed without the glasses. Sony does include two of these active shutter glasses, which is a good value in itself as many TV makers include only one pair typically and require you to buy additional pairs.
In terms of connectivity, you'll find two HDMI ports, a component, composite and a USB port on the side and two HDMI ports, a composite, a 3D sensor port and an Ethernet port on the backside. There is also built-in Wi-Fi wireless connectivity, which allows you to connect the KDL-55NX810 to the Internet services that it supports (connecting via Ethernet is also available). The Internet sources supported include some of the following: Netflix, Hulu Plus, YouTube and Sony Bravia Widgets (news, weather, etc).
Performance with the Sony KDL-55NX810 is absolutely visually stunning. Because of the glossy screen, the picture looks fantastic, but again, glare is easy to see. The brightness and contrast output of this 55-inch LED display is very wide ranged and the black levels are extremely deep. The picture did look best when the backlighting was set to a minimal amount, which again suggests this TV is best used in a dark environment, such as in a basement home theater setup. As we also stated in the beginning of this review, Sony's MotionFlow technology greatly reduces motion blur in fast-moving images.
3D image performance, while still quite new technology, was decently good. While we aren't necessarily a big fan of 3D TV technology at the moment, we were pleased with this model's performance. We really like that Sony includes two pair of the active shutter glasses, which are required to view 3D content. The 3D "sweet spot", which is an invisible area in front of the TV where 3D looks best, was fairly limited in space, so don't expect many people to be able to watch it at once and get a really good experience. The glasses are quite expensive and require batteries, so keep that in mind if you intend to buy a few extra pair.
