Sony XBR-55X850B 4K Ultra HD 120Hz 3D LED TV Review

Sony XBR 850B

The XBR850B is a 55″ 4K UHD TV that is part of Sony’s premium XBR HDTV line-up. This model ranks just below the XBR900B and XBR950B. The 900B and 950B are excellent performing 4K displays, and after reviewing these two models back in June (see here), I consider these two of the best HDTV’s currently on the market. So how well does the 850B stack up against it more expensive counterparts in the XBR Series?  Continue reading to learn more.

Design/Features

The 850B is available in 49″, 55″, 65″ and 70″ models. This review applies to all screen sizes.

The 850B features a sleek design with a very thin black bezel which gives the set an almost frameless appearance, and will fit nicely with just about any room decor. The feet of the TV’s stand are adjustable and can be moved inward to fit atop a smaller size cabinet.

For sound reproduction, this set has two full range speakers mounted at the rear and bottom of the TV’s panel. I will state now that the sound quality of these speakers was only average, producing a thin and lean sound, with weak dynamic range and no bass punch. However, this is typical performance for most flat panel displays. So as usual, I highly recommend a decent sound bar or stand-alone surround sound system.

The XBR850B features Dynamic Edge Backlighting w/ Local Dimming. This design will increase the sets black level capability and deliver a picture with better contrast and color vibrancy. The light output on this  display is very good and produces a bright dynamic image, which is fairly common of most LED TV’s.

Two key features that aid in giving the 850B its great picture quality are its TRILUMINOS display technology and Sony’s 4K X-Reality Pro Engine video processing.

TRILUMINOS technology creates incredibly true, natural shades of colors that are rich and vibrant, and delivers overall better picture accuracy.

The 4K X-Reality Pro Engine enhances Ultra HD, HD, and SD images by analyzing and refining images with natural detail and excellent color. The 4K X-Reality Pro Engine also up-scales all non-native 4K images to Ultra HD quality.

To help reduce motion artifacts, Sony’s MotionFlow XR 240 technology feature a precise backlight control that is synchronized with the liquid crystal movement from frame-to-frame creating clearer, sharper moving images.

If 3D viewing is a feature you enjoy, this set provides this capability and includes two pairs of passive 3D glasses.

This set give you a choice of Ethernet or Wi-Fi connectivity to your homes network to enjoy the Sony Entertainment Network smart TV platform. Once connected, you get access to numerous entertainment option which include Video Unlimited which features the latest movie and TV releases.  Music Unlimited – a music streaming service which offers a catalog of millions of songs.

For movies, music and other television entertainment, you get your usual assortment of apps including Netflix, Amazon Instant, YouTube, Vudu, Hulu Plus, Pandora and many more.

Another cool function of Sony’s smart TV platform is Social View. This feature allows you to watch live programming with other viewers via the built-in retractable camera mounted atop the TV. You can then see and interact with family and friends in a different location.

Surfing the internet is made easy with the displays full web browser.

Remote Control

Touchpad Remote

Touchpad Remote

This set includes two remotes. The standard type IR (infrared) remote is nicely designed with an easy to use button lay-out. It provides many direct access buttons for on-the-fly connectivity to sources such as Netflix and Sony’s own SEN apps,Social View – which loads the social networking app mentioned above, Discover for searching web and TV content by category, and Football for activating the TV’s sports picture mode. The remote is not backlit.

You also get a touchpad remote. With this remote, basic operation of the TV’s functions and settings can be made by sliding and pressing your finger across the touchpad. And thanks to this design, videos, photos, or even Internet content (like Netflix) can be accessed with just a swipe or flick of your finger. To use buttons that are not on the touchpad remote control, use the on-screen key pad instead.

Performance

The XBR850B delivers beautiful  4K UHD images. Color rendition on this set  was very realistic and true-to-life. The Sony demo footage I viewed of a woman singing on stage in a red dress against a black back ground was very stunning. The red  dress she wore simply popped from the image, delivering a very rich and vibrant color palette, which contrasted beautifully against the black background in the image.

Flesh tones of this female vocalist were very accurate while showing plenty of fine detail in her skin.

This display also performed very well with black level reproduction. As I watched the same demo footage noted above, the 850B produced deep saturated blacks which were rendered quite nicely throughout the background of people in the audience enjoying the vocalist performance. Shadow detail was rendered well enough that I could make out fine detail in the dark background of this scene, as well as faces in the crowd.

Image depth was very good, allowing me to see deep into the background of the image even thought the scene was very dark.

4K Upscaling. To evaluate this sets upconversion performance, I viewed several scenes from the blu-ray edition of  X-Men Days of Future Past.

Let me begin by saying from the start – the 1080p images produced by this 4K TV were absolutely amazing, producing some of the best images I have ever seen. Period. The detail and clarity of the images were simply first rate. Close up shots of individuals and objects  delivered so much fine detail, that it made the images appear very life-like.

And honestly, if I didn’t know any better, I would think the picture I was viewing was actually true 4K and not upscaled. That’s just how good this sets 4K X-Reality Pro Engine video processing technology really is.

With that said, I would purchase this set for its 4K upscaling capability alone, even if I didn’t plan on viewing any 4K content right away. Its performance is that good.

XBR850B vs. XBR900B and XBR950B

I’ve had a lot of good things to say about the 850B in this review. My following comparison comments are not meant to take anything away performance wise from this excellent TV.

The 850B does not have the X-tended Dynamic Range Pro (950B) and X-tended Dynamic Range (900B) picture enhancing technologies. These technologies alone set the 950B and 900B apart from the 850B, and is key to their better picture quality when compared to the 850B.

What  X-tended Dynamic Range Pro and non-Pro do for picture quality is to provide brighter whites and deeper blacks for outstanding contrast reproduction.

Note: The 950B has full-array LED backlighting with local dimming. While the 900B has edge LED backlighting with local dimming (same as 850B).

Due to the technology differences, the 850B images do not provide the same brightness,  contrast and black levels as the 950B and 900B displays. For example, the 950B’s picture is brighter, sharper and more transparent. Picture detail  is also  better and more refined.

Another big stand-out is black level and shadow detail reproduction. The 950’s blacks are extremely dark and inky black. Shadow detail shows much more detail in dark images. For example, objects in dark scenes on the 950 could be plainly seen. However, objects in the same scene on the 850 could not be seen or were sometimes obscured. The 900B had similar results when compared to the 850B. Just not as apparent.

Conclusion

As I said earlier in this review, my goal was not to detract from or discredit the performance of the 850B during my comparison. On the contrary, this is an excellent 4K display, and has earned its place alongside the other 4K TVs in the XBR Series. It is only when compared directly with the other two sets in this series line-up, will you begin to see and/or notice picture quality differences.

The XBR850B is loaded with many useful features, and its picture quality should satisfy most any consumer looking for a great performing 4K Ultra HD display. For the record, I could personally live happily with this television in my home. Highly recommend.

  • I like your writeup. I think I would’ve liked more pictures when you were doing your comparisons.

  • Thanks for the great information here. I currently have a sony which I’ve had for a few years I’ve been really happy with it. For us it has been everything we wanted so I will probably go for a Sony again I tend to be pretty loyal. Just wondering if you have any idea how much power they use. We noticed a small difference in our bill when going from a panasonic to our current TV so it’s something I like to consider.

    • Hi Vicki, thank you for your interest in this review. I did a bit of research for you regarding the energy use of the televisions mentioned here. According to the “Energy Guide” yellow tags that accompany these TV’s: The XBR-55X850B has an estimated yearly cost of $22.00. The XBR-65X900B has an estimated yearly cost of $27.00. The XBR-65X950B has an estimated yearly cost of $31.00. This is based on 11 cents per kWh (kilowatt-hour) and 5 hours use per day.

  • I currently have this set and still have time to return/exchange. Im wondering if the samsung hu8550 would be a better choice? Thank you

    • Hi Joe, the Sony XBR-55X850B is an excellent television. However, when compared to the Samsung HU8550 (see review here), I experienced a notable increase in overall image quality. It wasn’t a huge or “night and day” difference,however. With that said, I could live happily with either set. But, if I had to choose between the two, it would be the HU8550. Joe, what matters most is which of these two TV’s image quality appears best in your eyes. And since you are wondering if you made the right purchase regarding the X850B, I suggest you have a look at the HU8550 and see which of the two you favor the most.
      Thanks for your question and taking the time to read this review.

  • I was wondering if you could list the processor differences in the TVs. I know the xbr850b has a dual core processor but I believe the xbr950b has a quad core processor. I know the Vizio P series has hexa core processors ( quad core cpu and dual core gpu) and was hoping for a break down of that for these TVs. Thanks

    • Hi Mat,
      I don’t have much detailed info on the processors in the TVs you mentioned in your comment. As you already stated, the Vizio P Series has a V6 six-core processor:quad-core GPU and dual-core CPU. However, the Sony XBR850B and XBR950B both use the X-Reality Pro engine which is a dual-core processor.
