The Sony X850E 4k LED TV offers better than average picture quality and excellent motion handling but lacks a handful of high-end features. It does best in darker environments, but it's still capable of getting bright enough to be used in lit rooms without issue. Unfortunately, it isn't the best fit for wider living rooms because of its narrow viewing angle.

Sony X850E Design Picture
Curved : No

The design of the X850E is sleek and minimalistic, in line with other Sony TVs. The familiar center stand supports the TV well, and provides some basic cable management. The borders are quite thin and the build quality is good as everything feels firm.

Stand
Sony X850E Stand Picture

The central stand supports the TV well and feels stable enough, but the plastic isn't as good as last year's metal stand on the X850D. It has a small footprint, ideal for those with narrower tables, and allows for some basic cable management down the rear tracks.

Footprint of the 65" TV stand: 10.4" x 19.8"

Back

Wall Mount : Vesa 300x300

The rear of the TV is quite basic, and if wall mounted some of the inputs may be difficult to access.

The build quality of the X850E is good. Screws hold the back together very firmly and there is no give around the frame.

Picture Quality

The Sony X850E has good picture quality. The excellent contrast ratio and black uniformity result in a very good movie experience, especially when set in a dark room. Bright room performance is decent, the SDR peak brightness paired with the reflection performance is just enough to fight glare from a bright light or window. The good gray uniformity of the X850E makes for a good sports experience without dirty screen effect, but due to the X850E's very narrow viewing angle it is better suited to a narrow seating area. The HDR performance is decent with a good color reproduction, but is limited by the lack of local dimming and HDR peak brightness.

The Sony X850E has a good contrast ratio. At around 4500:1, it is a big step up from the 2016 X850D (IPS TV) which had a contrast ratio of only 1248:1. The higher contrast ratio of the X850E results in deeper blacks which in turn make this TV a good choice for watching movies in a dark room.

Update 05/12/2017: Readers have reported that the 75" model has an IPS panel, so the contrast ratio is expected to be around 1000:1.

Good SDR peak brightness, very similar to last year's X850D. The brightness remains relatively constant no matter the content shown, because the TV lacks local dimming and uses very little frame dimming. The real scene brightness is a little less because it is measured near the edge of the screen where the TV is a bit less bright. A plot of brightness over time is found here, and shows that the TV's brightness doesn't decrease over time even when showing a static image.

Good HDR peak brightness, very similar to the X850D from last year. The TV lacks local dimming and shows very little frame dimming, so the brightness remains relatively constant for all content shown. The screen was brightest in the middle and less bright near the edges, so the real scene brightness is a little less because it was measured near the edge. A plot of HDR peak brightness over time can be found here, and shows that the TV remains bright even after showing a static image for a long time.

The overall gray uniformity of the X850E is good. The uniformity of the 50% gray is a bit worse than the 5%, and while looking at the test picture, you can see that both sides and the top of the screen are darker than the center of the screen. Luckily, there is not much dirty screen effect visible on this TV and sports does not suffer much from it since the center of the screen is pretty much even.

Looking at the test picture of the 5% gray you can see that that the sides are a bit more bright than the rest of the picture, but this is more related to the narrow viewing angle of the X850E than to a uniformity problem.

Poor viewing angle. Colors shift and blacks become gray when the TV is viewed on the side. People sitting to the side of the TV will not have as good picture quality as people sitting directly in front. Last year's X850D has a much better viewing angle because it has an IPS panel.

The black uniformity of the X850E is excellent, and it is a significant improvement over the 2016 X850D. Looking at the test picture, some really faint clouding can be seen in each corner, but this is really not a problem, and it doesn't show up when watching regular content. When set in a dark room, the X850E really does a good job as displaying dark scenes when watching movie.

Since it does not have local dimming, some clouding may be visible when displaying a bright highlight, but it is not because of native black uniformity problems but more a limitation of the backlight technology used in this TV.

Calibration of the X850E is easy and pretty fast to do. The white balance dE was brought down considerably, and the gamma curve flattened to closely track our goal of 2.2. The color dE was also brought down, but could not be brought down further, since, like other Sony TV, there is no color space management.

The X850E has excellent motion handling due to the fast response time. Only a short trail can be seen following fast moving objects. The backlight doesn't flicker by default which is great, but it is possible to enable flicker to clear up motion. Movies from a Blu-ray player appear smooth, but some minor judder is present when watching movies from a home theater PC or cable box. This isn't noticeable for most people so isn't an issue. The TV has a 120Hz panel which can interpolate lower frame rate content.

The Sony X850E runs Android TV, which tends to be more difficult to navigate than other smart platforms but also has access to the Google Play Store, which has more apps and content than many other platforms. The 'Action Menu' button on the remote helps to relieve the navigation problem by showing a quick list of many common settings so users don't often have to navigate to the main settings menu. The remote's voice search button also helps with navigation by allowing the user to open apps and search for content directly. Content can be played from USB drives plugged into one of the TV's three USB ports, and the TV's Chromecast Built-in feature allows content to be cast from other devices to the TV.

The first row on the Home screen shows suggested content. It is possible to disable all sources of suggested content until all that remains is a line saying "No recommendations available at this time". However after all sources of suggested content have been disabled and the TV has been restarted more sources will appear that were not listed before, so the process must be repeated a few times.

The remote is rather large and has a lot of buttons. A cluster of buttons around the direction pad serves as the centerpiece of the remote, and ensures that most of the common buttons are within easy reach. The remote has a microphone for voice search, which is activated by pressing the microphone button.

The remote's buttons aren't as easy to press as on the remotes of the X900E and last year's X850D, because each button is a separate chunk of rubber rather than part of one uniform surface.

Differences between Sizes and Variants

We tested the 65" (XBR65X850E). 

Update 05/12/2017: Readers have reported that the 75" model has an IPS panel, resulting in a lower native contrast ratio but the image remains more accurate when viewed at an angle.

If someone comes across a different type of panel or if their Sony XBR-65X850E doesn't correspond to our review, let us know and we will update the review. Note that some tests such as the gray uniformity may vary between individual units.

The LG UH8500 doesn't offer the same value found on the X850E. It is less expensive, but picture quality is significantly worse. Blacks aren't as deep and uniformity leaves much to be desired. Picture quality is retained better at an angle, which gives it an advantage for those with a wider living room. Most people should otherwise get the X850E.

Sony X900E
49" 55" 65" 75"

The Sony X900E is a slight step up over the X850E. It's a similar TV, but adds features such as local dimming. It also gets brighter, so it is a bit better for HDR movies. If you're a bit of a movie buff and want the best home theater experience, it might be worth spending more on the X900E.

Samsung MU8000
49" 55" 65" 75"

The MU8000 is a similarly priced LED TV from Samsung. It performs very similarly overall, but gets a little brighter and has slightly lower input lag. The X850E has a significantly wider color gamut though, which is quite beneficial for HDR. Either is a good choice, but since the Sony will usually run you a little less, it is the best choice between the two.

Vizio P Series 2016
50" 55" 65" 75"

The P Series is Vizio's flagship model from 2016. Not only does it feature local dimming which the X850E lacks, it does it better than almost every other TV we've reviewed. Overall, it will perform better for most usages, but the biggest differences will be found with video games or movies in a dark room. Most people should pick it instead of the Sony.

Additional Review Notes

When in the graphics picture mode 1080p is displayed with very basic upscaling, just mapping one pixel to four. This is the same behavior as seen on the X900E, and is shown in the X900E's pixel picture to the right. This kind of upscaling looks more jagged but it retains all the sharpness of the original image, unlike the softer upscaling from the other picture modes. However 1080p @ 120 Hz does not show the same behavior; in both game and graphics modes it uses a different jagged upscaling that is a little softer, but is still more jagged than normal.

Hi there, first of all, thank you for having the best and friendliest tv-comparison tool up on the web. Behind all the technical insight you provide, what were you own consumer thoughts when watching movies in the dark? Were there a few "I wish it was brighter" moments or was the illumination wholesome? And does the sub-500 nit count manage to keep black crush at a minimum during your testing? Thanks again, and btw, the idea to include the different appellations of reviewed models is fully appreciated.
Thanks for the kind words. When watching TV in a completely dark room, the X850E with around 400 cd/m² has sufficient brightness. You should not have any brightness problem with the X850E. As for the black crush, often a calibration with simple patterns can take care of any black crush and Sony X850E has a lot of settings you can use from the 'Brightness' tab to help you adjust it correctly.

Hey guys love the reviews, so I just bought an X850E and I have my Xbox One S hooked up to it but I'm not getting full HDR 4k support at 60 Hz. What am I doing wrong, it worked on my Vizio M series. How do I turn on the "HDMI Enhanced Format"?
"Home" button on remote, "Settings", "External Inputs", "HDMI signal format", "Enhanced mode", to enable HDMI 2.0 full bandwidth on HDMI ports 2 and 3. The Xbox One S requires this to be enabled for 4k HDR.

What is the black value of this tv? I see the contrast 4510:1 but no black value. I thought you all posted that?
We added 'Contrast with Local Dimming' to the Contrast box, so to simplify the box we removed the black and white level measurements. If you want to calculate the black level, the test is always done at 100 cd/m2 white, so if you divide 100 cd/m2 by the contrast ratio you'll get the approximate black level.

As always, your reviews are amazing. I personally use this site to train my employees on TVs, and more than a few of them have noted that this year seems to be Sony's return to form. I impatiently await the scoring for the Z9D and A1E models, as well as the non-OLED LGs and the rest of the MU series from Samsung.
Thank you for the kind words! Sony seems to be very competitive this year, and their TVs are getting very good scores, and yes we are very curious too to see how Sony's OLED is going to rank up against LG's OLEDs. The coming weeks are going to be very interesting as we are planning to review Sony A1E very soon.

Just to be sure, this Sony model does 1080p @ 120hz @ 4:4:4 through a custom resolution with no artifacts or compromises? Also does that mode significantly change input lag?
No artifacts or frame skips, and 4:4:4 color is properly displayed when in game or graphics mode. The upscaling is really jagged though, almost one pixel to four, see our additional review notes here. We can't measure the input lag at 120 Hz because our industry standard Leo Bodnar tool can only measure lag at 60 Hz, but input lag is usually less at higher refresh rates.

It seems like a lot of these new televisions that don't have local dimming don't get very bright. I have an old Panasonic VT60 plasma which I think is bright enough so I'm assuming when you say the Sony 850XE doesn't get very bright it would still be way brighter than my plasma. Also, I found an old Samsung 75 inch JU7100 brand new which I'm thinking of purchasing. In your opinion which is better the Samsung or the Sony 850XE?
You are right, the X850E will be brighter than your plasma TV (and brighter than any plasma TVs). If you are looking for a 75" TV, then the X850E might not be the best option, since the 75" version of the X850E has an IPS panel, with a lower contrast ratio, less deep blacks, and a lower picture quality, especially when viewed in the dark. In that case, the Samsung JU7100 would be a better TV.
