Once considered a manufacturer of electronic products leading in all, Sony is still a big fish in a much larger pond. The company continues to produce high quality products in the industry, and its latest generation of HDTV is no exception. At $ 2,799.99 52-inch Sony Bravia KDL-HDTV 52NX800 edge-lit LED baded LCD may seem expensive for a non-3D HDTV and its image quality is not perfect, but a sleek design and thoughtful features such as integrated cable management and Wi-Fi, could also contribute to this series to justify its price.
Not too long, LED backlighting is a feature some a premium LCD HDTV series. Now you can find anywhere, including six series of Sony BRAVIA LCD HDTV programming in 2010. The first three of the LX900, HX900, HX800 and series or 3D measurement of the box (the XBR LX900) and 3D ready. Another step in the new line is the series Sony BRAVIA NX800. 2D in the nucleus, these 60 -, 52 - and 46-inch models use LED lighting board. The LEDs are positioned behind the frame of the series, usually on the sides. Speakers then light to provide (theoretically) uniform lighting on the back screen. This is different backlight LED full, which organizes the LEDs in a large number of clusters behind the screen. LED edge lights requires fewer LEDs , use consume less energy, and makes possible great production of very thin. Although some local dimming sets LED backlight, LED lighting device  set does not.

Brilliant Design

The appearance ultrasleek KDL-NX800 as a flat sheet black when turned off, dominated by a single pane of glass that extends almost to the edge of the panel on all sides. A piece of black metal edges of the glass panel, and when viewed from the side or top, black brushed metal brushed silver complement the subtle support low profile. Behind glass, relatively thick edge around the screen is almost black widescreen, promoting the illusion that the TV is unique. The logos and indicators are extremely thin, at least until the word Sony fires when the TV is on - the light can be disabled in order to promote an integrated view of the screen.
Sony has also paid attention to how the rear and side of the monolith appears. TV toothed profile measures 2.5 inches deep the thickest on the bottom, which reduces to an inch on the top thinner. The company glossed the black rearside, and hid the input connectors on the back behind a removable plate. You can then channel cables down into the base, along with the power cord - even if the space is a bit close to the thickness. Speaking of the position, finally Sony has added a pivot, which the company has never added to an LCD TV. In addition to the pivot, the TV, strangely, may be tilted slightly - if you want to mount the NX800 on the ground, perhaps?


Sony has also given the TV remote control is a major transformation. And "one of the best remote we've ever used, apart from the odd dual power button on the back that made us turn off the TV once. The company has maintained the excellent layout of buttons on the remote control last year, maintaining the logic of investment and differentiation. However, the keys this year are more flush and elegant, enhanced emergency response - now emit a satisfying click softly. The remote is curved along its entire length that seems to send the Home button on your thumb and the middle of the cursor control naturally. Completing the package, Sony added blue backlighting and the ability of CAP to control other devices via infrared or HDMI.

Picture Quality

The KDL-52NX800 includes 12 picture modes, but I only used the custom mode. Besides all the usual controls, the set includes an Advanced Settings menu (not available in all modes).This option allows you to make additional adjustments, including adjustment of white balance for the calibration setting the gray scale. Out of the box, the warm 2 setting the color temperature the more accurate of the four setup. The Black Corrector control has not done much. The Advanced Contrast Enhancer (ACE) appeared to lower setup the black level subjective, but also produced a series of strange static gamma curves. The visible effect of this gamma range was surprisingly delicate. (Remember, we can measure the static gamma and dynamic control by ACE). However, this control crushed shadow detail in dark scenes as well. Ultimately, I disabled all the controls in the advanced settings menu, with the exception of white balance, I adjusted during calibration, and Gamma, I left the default setting zero.
The KDL-52NX800 operates at a refresh rate of 240 Hz, Motionflow 240Hz Sony is going to function to reduce motion blur, and has three option (OFF, low, high). If you select Motionflow 240Hz in one of its active settings, Sony will add nine interpolated to each frame of a true 1080p/24 source to take the refresh rate of up to 240 Hz. If the source is either 1080p/60 (or 30 fps interlaced, deinterlaced all setup ,and, if necessary, upconverted to 1080p/60), The Sony will add three interpolated frames to achieve the magic 240.When the Motionflow switch - off, the picture still needs more extra frames, but they repeated their instead interpolation them.
Motionflow 240Hz works as advertised. The film-base material, it seems to interact with the CineMotion control. Its effect is more noticeable if you set it on Auto 1. The video-based, Cinemotion neither helped nor diminished Motionflow 240Hz operation. However, as in other similar setup, Motionflow 240Hz has unfortunate side effect of making films based source look like video. If you like Lord of the Rings “ The Days of Our Lives of Middle Earth”, it could be this way. not me, so I turned off Motionflow 240Hz for all tests and my screen (default is committed outside the box).
The video controls can be set separately for each item, including checks of the white balance. There is no copy function, so if you want to use the same settings for more than one item, you must manually transfer them. No other video services that we tested, namely YouTube and Amazon Video On Demand, showed unusual problems with video quality. Minor video services abound on the NX800, including Sports Illustrated (not sports - any movie clip swimsuit model, when we checked), the Minisode Network,,, and Many video podcasts. Besides Amazon VOD, the picture quality of other video services is generally poor, believe that non-HD content on YouTube. This is probably because most of their content is designed for the web. Free videos from CBS to provide quality generally good, but do not expect anything near the quality of, the official web portal of the network for full TV episodes. Instead, there is a hodgepodge of clips and full episodes rare. We know that Sony has added a keyword search in minor services, but it would be much more useful if the search included all video services, including YouTube, Amazon, Netflix, and - while we - even the TV Guide EPG information.


Although modest mitigation HD chroma highest test frequency, the resolution of subjective Sony has been excellent. I could easily make the difference in sharpness between a single show Blu-ray Disc and beautiful one. The HD video quality on average from the invention of the Lying was clear from the outset. When I popped in Pirates of the Caribbean: The Curse of the Black Pearl, I saw how cool this series can look with exceptional video transfer. The Sony on occasion look at oversharp shadow (with the Sharpness control to zero), but this occurred only a few separate scenes. I have not seen any evidence of sharpness from test pattern discs . The set just seemed to serve as sources as they were.

Black level : Compared to other series in our ranks, Sony gave the NX800 a shade a bit ighter shade of dark after calibration, with the exception of LG SL90, which was much worse in general. In scenes dark as when Mark Whitacre called Shepard lot of Econo Lodge parking in Chapter 10, or the night sky at the beginning of Chapter 17, and the black shadows on XBR9 and B7000 have been a little darker than on NX800. In addition, as expected, the overall local dimming control and plasma Pioneer has also had darker black levels. The Sony seems a bit more natural when you look at the details because the XBR9 details, however, was not much better (and in some cases worse) than any other series.



The uneven level of black Sony is a kind of fly in a pot also very tasty. You will not see often. Some of you may not see at all, especially if you do not have many observations in a dark room. But, as with another set of edge-lit that we tested, it’s our enthusiasm tempered a set of this price range. However, the material sources, the Sony Bravia KDL-52NX800, properly configured, produces a wonderful, rich colors and natural, excellent resolution, video processing respectable, and the contrast is almost always impressive.
