Sony KDL55NX720 Review

55" Bravia LCD LED TV, 3D, 240Hz, X-Reality PRO Engine

The NX720 is another mid tier 3D LED TV from Sony, this one has the Gorilla Glass, Monolithic Design and X-Reality PRO processor but is 240Hz rather than the 480Hz of the top line models.

Gorilla Glass is a high tech glass from Corning that is expcentionally strong and extremely thin. Sony uses it in it's Monolithic Design TVs and is a component of their OptiContrast Panel, Sony says the thin glass allows the image to appear closer to the front of the TV and provide more picture depth. Sony calls this "Image Elevation Technology".

Picture and Viewing Features

During recent viewing with sources from 3D Net we noted some blurring during fast motion scenes on the HX920 series. We noted the same during some Cinema 3D and Sports 3D programming. Bright lights against a dark background are particularly alarming. That said the X-Reality PRO dual chip processing engine is fantastic at processing normal 2D signals – even fast motion. The TV has a fantastic picture quality with non-3D sources with incredibly deep black levels and eye-popping definition. Colors are rich but not oversaturated.

Unlike many of Sony's competitors 240HZ rate features, we actually like Sony's. In past TVs it was the only one that alleviated blur without adding jarring effects to the picture. In our reviews you will notice Sony was one of the few televisions where we did not suggest turning this feature off.


The new monolithic design from last year is present on the new NX720 series. The edge lit LED LCD TV is around 1 inch deep and the screen glass expands all the way to the edges. The look of the TV is stunning and is one you'll want to show off.

Internet Applications and Connectivity

Sony was the first out with a true Internet TV this past fall of 2010 with the GT1 series, enabled with Googles Chrome browser. The NX720 does not have the Google TV application, but it does Sony's new Bravia Internet Video and Qriocity functionality which has among other premium Internet TV Apps HuluPlus, Pandora, Amazon VonD, You Tube, Slacker Internet Radio, Crackly, Hmm why am I not seeing Netflix here? Must be a typo in the specs from Sony.

Standout Features

Motionflow XR 240, one of the few manufacturers with a high refresh feature that we actually leave on.

Edge Lit LED backlighting, 3D TV ready.

The new X-Reality Pro Video Engine is a two chip processing engine rather than 1 used in the normal X-Reality engine. It is quite useful in that it upconverts and improves the picture from low resolution Internet content sources. It also optimizes high definition content, compressed HD signals, standard definition, and other sources. By utilizing a vast database of "ideal" signal patterns developed by analyzing and indexing and enormous library of film and video, the X-Reality PRO Engine compares incoming signals pixel-by-pixel with ideal scenes to display vivid and detailed images.

The embedded Skype features has increased resolution to 720p high definition to receive better images when video chatting.


4 or more HDMI inputs should be plenty on any TV. 1 rear ethernet port, 1 side USB port, 2 rear Component video inputs.
