Samsung UN55B7000 LCD HDTV are edge-lit LCD models equivalent to local projects glare, as Ms. Samsung proclaimed? Based on the evidence here, not quite. But they are much closer than I expected, and have much to offer greatly less money.

Slim and Smart
Samsung present to the models 7000 series(and many of its new all), such as LED HDTVs, but LED design only to the type of backlight. Technical, the backgrounds are still LCD.
The Samsung UN55B7000 LCD HDTV are the largest set of the 7000 series. slim size at 1.2 inches, It is the thinnest HDTV we've reviewed. The output routing is necessary for the power cord and it’s input jacks and exit to the side or bottom, help you from doing absolutely flush wall-mount. But it’s can still close up to your sheetrock than other production we have seen. At 61.3 pounds (with stand), the UN55B7000 LCD HDTVs series is also easy to lift up. Thank you for this, because I often called to schlep around 125 pounds, 60 inch plasma.
Setup and Control
Samsung contain two different remotes as UN55B7000. A mini remote control, antenna-shaped egg, and turns the set on-off, adjust volume and change channels. But since you can use the selection of channels with the tuner, the remote must be of limited use if you have a satellite or cable viewers (unless you watch unencrypted cable channels with a direct cable feed to the set without cable box).The larger remote is handy buttons enormous size, fully lit, and is one of the best I’ve seen. It only flaw (a common) is that the input selection is via a menu on the screen, rather than direct selection by the remote.
The Samsung UN55B7000 LCD HDTV has six modes of picture, and they are all separately adjustable for each input. In addition to the usual video controls, including a backlight in 10 steps, there is a wide range of other adjustments. Perhaps the least common one is a blue frame. for turn-of the red and green, this feature provides an accurate tool for defining the color and tint with a color test pattern. The usual technique for obtaining these setting right requires of a special filter blue, which is not as accurate.
Many special controls in the setting are only available in standard and cinema mune. These include a seven-step Gamma adjustment, color space (a system of color management with a comprehensive set of controls for optimizing the color gamut), and white balance controls(high and low for the three colors).
It also has a way of regulable the movie mode and picture-in-picture (PiP). The controls I did not need and do not use colors are black, Dynamic Contrast, Edge Enhancement (FIE, Satan!), Digital noise reduction, and xvYCC. The Samsung has two USB inputs which can be used to display photos, music and video (including HD video), the recorded in a compatible format. DLNA is also available play of material that is stored on your computer through your home network.
New for 2009, Samsung added widget for Yahoo for its high-end sets including UNB7000 LCD HDTVs series . The module collects information on the Internet powered, called "snippets" in a bar along the bottom of the screen, and each can be activated to reveal the widget for all purposes. The model we reviewed came with widgets for stocks, weather, news, and access to Flickr photos, and we expect more widgets are coming soon. See our full review of Yahoo Widgets for more information.
While the menus at the Samsung is good, I have some quibbles minor. The most important of these is that the time is too fast, which can be a important problem in trying to calibrate the gray scale and color space. If you do the calibration settings individual menus, for each setting are at the bottom of the screen where you can see, but they are out of the way of the measuring device. But before taking the measure, the time out menus and return to the previous menu full-screen that blocks the instrument.
Edge-lit LED-based LCD
In most LCD sets, the backlight is placed behind the LCD screen with a speaker that provides a relatively uniform illumination across the screen. In the first series with LED backlighting, LED simply replaced by the cold cathode fluorescent more frequent (CCFL) backlight.The LEDs are placed behind the screen in small groups of red, green, blue devices (or white LEDs, with an appropriate approach filters-Samsung) have an advantage over CCFL you can easily dim or turn-off them. This has led to the development of sets of local dimming LED. In this setting(currently only a handful of models), the LED are dimmed by zone in response to the characteristics of the source. This might strengthen the blacks, if necessary, without dimming the bright areas of the image.
So what is that thing with the edge of LED lighting? separately from the cost (LED backlight requires a lot of LED), a major problem with backlight behind the screen, and this limits the total fine may be. The producers are super-thin that the public wants a new approach. If the backlight can be placed along the edges of the screen and directed if necessary, thin is in. This can be difficult with CCFL, but the LEDs are ideal for this approach.
The UN55B7000 uses Edge-lit LED technology lighting board. Although true local dimming is not possible with this design, edge lights, you can control the screen more easily than illumination with fluorescent. Samsung descriptions do not speak, but my observations indicate that, in order to deepen the level of black and dark gray, The dimming UN55B7000 there is a certain extent. In fact, there were moments when the Samsung black screen disappeared at the total between scenes. However, this was rare and depends on the video configuration. Most of the time, with the set well adjusted, it is simply down to a shade of gray, much deeper than what you see on all traditional LCD.
The edge lights sheds light UN55B7000 not completely uniform illumination, but it was clear that with a screen image of totally black,full-screen in a completely dark room. In this situation, the edges and corners of the screen, while still respectable dark, were much lighter than the center. I never noticed the brightness of the screen is not uniform over the normal program material.
Samsung's performance is so surprising that it only weakness is here even more evident. As you move off center, the picture begins to deteriorate. It's good for two people on a sofa or three that are either very friendly and not too demanding. But if you move more than 25 or 30 degrees from the center, the black level starts to increase dramatically, destroying the contrast ratio and brilliant colors fade the axis of the assembly. A word of caution consumers: the problem will become less visible with the parameters of ultra-bright image used in a showroom.
Summary

If the last paragraph is that a few downer, I must say that the Samsung has a lot of businesses here. Degradation of the image off-axis is a problem with most LCDs, and it is probably the last major weakness of LCD models now that the black levels (the best series) have improved considerably. However, The Samsung does not have much company when it comes to extraordinary combination of colors, deep blacks, shadow detail view, the precise resolution , and exceptional video processing. If you are looking for a first-class LCD, but can not completely cover the development budget to local-dimming design (a room-darkening Samsung size is the same for $ 5,000and $ 7,000 for a Sony) This set deserves a look very close.
