xbr65x800b lcd panel quotation

A T-con board — short for “timing control board” or “timing controller” — is found in LED and LCD TVs. This board converts the video signal from the main board and sends it directly to the screen to display the signal in the correct order and at the correct spot on the screen.

Sony’s XBR65X800B is part of the company’s premium XBR lineup. This new model was released in December 2014/January 2015; however, it technically isn’t part of their upcoming 2015 model releases which will hit the streets this spring. Nor is it officially part of last year’s 2014 model line.

The XBR800B isn’t your typical black or charcoal-colored front panel design. Instead, it is an eye-catching silver platinum finish that distinguishes it from most other displays in the HDTV landscape. Sony has also trimmed down the overall size of this set when compared to last year’s models.

The feet on this display can be adjusted to fit at the outer edges of the TV’s panel or be positioned near the center of the TV’s panel. These placement choices are all about consumer preference. The TV can also be wall mounted.

The display panel contains two down-firing full-range speakers placed at the bottom and on the backside of the set. I will talk more about their performance later. The TV screen has a matte finish that in my opinion can sometimes give the on-screen image a dull appearance. Personally, I prefer a glossy screen finish which I believe gives the image better transparency and clarity. With that said, this TV’s matte finish didn’t appear to affect its picture quality.

Even though the XBR65X800B is a lower-end XBR model and is minus the two-key picture enhancing features mentioned above, it still delivered very good picture quality. One of its strong points is color rendition. The colors produced on this display were rendered with very good tonal balance and accuracy. Colors were also very vibrant and showed no excess saturation effects. I also appreciated the natural look of the color palette produced on this display.

The sound quality of the onboard speakers on this TV, was to no surprise, very inadequate. I experienced your typical lean and thin sound which was lacking in bass response. This is an all too common occurrence in most flat-panel TVs. With that said, my usual recommendation is to add a soundbar for better audio performance.

Even though the XBR65X800B falls a bit short of delivering performance at the same levels as its more expensive XBR Series counterparts; on its own, however, it does manage to deliver very impressive picture quality. You also get a nice assortment of features all wrapped up in an attractive slim profile design.

2015 is poised to be a very good year for 4K Ultra HD TVs as more displays become available and at much lower prices. So if you’re thinking of joining the 4K revolution this year, why not start by having a look at Sony’s XBR65X800B.

There are various panel technologies. Each has its own specific features - viewing angles, color reproduction, response time, brightness/contrast, production cost, etc. The image quality depends directly on the type of the display panel used.IPS

The most widely used panels are those with 6, 8, and 10 bits for each of the RGB components of the pixel. They provide 18-, 24-, and 30-bit color, respectively.10 bits (8 bits + FRC)

Frame Rate Control (FRC) is a method, which allows the pixels to show more color tones. With quick cyclic switching between different color tones, an illusion for a new intermediate color tone is created. For example, by using FRC, a 6-bit display panel is able to show 16.7 millioin colors, which are typical for 8-bit display panels, and not the standard 262200 colors, instead. There are different FRC algorithms.Yes

The maximum number of colors, which the display is able to reproduce, depends on the type of the panel in use and color enhancing technologies like FRC.1073741824 colors

The backlight is the source of light of the LCD display panels. The type of backlight determines the image quality and the color space of the display. There are various backlights such as CCFL, LED, WLED, RGB-LED, and etc.Edge LED

Slim, matte-metal bezels wrap the panel from top to bottom. Since it isn"t shiny, the TV"s border fades into black when you turn out the lights for movie night. Wide-set metal feet prop the TV up with a bit of flare, but take heed and mind your measurements: The feet can attach on either end of the panel for a wide stance, but then the TV may not fit on your entertainment stand (in which case you"d need to attach the feet toward the middle of the panel).

If there"s one thing to know upfront about Sony"s X850B 4K TV, it"s that this panel (calibrated or not) is best suited for an illuminated room. This isn"t ideal picture quality for dark-room viewing, period. Barring that, brace yourself for massive 3840 x 2160 resolution and praiseworthy picture quality.

The X850b"s black levels are average, at best—which is why it looks best in a partially lit environment. To make matters worse, uniformity issues plague its corners. Uniformity refers to unwanted light that bleeds into dark areas of the screen (a common issue with edge-lit LED LCD panels). While watching The Hobbit in the dark, the black bars that sandwich the film looked too bright in the corners. The blotchy light leaks became especially annoying during very dark scenes. I"ll say it again: This TV is not ideal for a pitch-black room.

Yelling, cursing, nacho-eating sports fans will fist pump for the X850B"s motion performance, too. Although the panel suffers a degree of mild blur and juddering during highly detailed, horizontally panning scenes, the behaviors are much milder than what you normally find on edge-lit LCDs. Sony also includes motion enhancement settings, such as Cinemotion and Motionflow. The former works specifically to improve cinematic content, such as Blu-rays, while the latter handles content regardless of source—and both modes offer varying levels of strength (Clear 1, Clear 2, Auto 1, Auto 2, etc.).

Lastly, lots of folks seem curious as to how 3D looks on a 4K panel. I can tell you, it looks terrific. Sony"s passive (battery-free) glasses are lightweight and comfortable, and watching 3D content for extended periods doesn"t tire the eyes. I did notice some mild ghosting towards the edges of the screen, but that"s nothing out of the ordinary. Coraline and a documentary on outer space looked particularly impressive and detail rich. It makes sense. 3D content utilizes higher resolution, after all, so the shoe fits.

In classic liquid crystal display (LCD) form, the Sony X850B LED LCD TV fails to furnish a wide viewing angle. If you tend to watch movies with gaggles of friends, you should consider other options. You could spend the same $2,000 that this 49-inch panel costs and score Sony"s 55-inch regular HD flagship—the W950—which has almost double the viewing angle of this X850B. Even better, you could invest in a plasma, which would offer nearly a perfect viewing angle.

Notice: Recommended to order by part number whenever possible. Often times there are TV models that use more than one set of parts and/or panels. Part number (6871L-3605E) can be found on the white barcode sticker on the board. Horizontal lines on the screen are normally never caused by a bad T-con board. Horizontal lines indicate a defective LCD panel.
