The Sony X850D is a good 4k LED TV for a living room. Its picture quality in a darker room isn’t as good as last year’s model, the X850C, but it boasts a better viewing angle and somewhat improved HDR capability. Because it doesn’t have much blur, sports and video game fans will enjoy the Sony X850D.

  • Great for fast motion content like sports and video games
  • Wide viewing angle
  • Blacks appear a little gray in the dark
  • Average HDR performance

Design

Sony X850D Design

Curved: No

The designers behind the Sony 4k UHD X850D LED TV have done a decent job of making the TV look good, but it looks cheaper than last year's X850C. It still feels sturdy, but most of the metal finish is gone; its frame and stand are now entirely made of plastic. The new stand feels more solid, though. The X850D is relatively thin, but those looking to mount it flush on a wall will block some of its back connections.

Stand

Sony X850D Stand

The plastic stand is very sturdy and the TV feels safe on it, although it can still wobble a bit if you push against it.

Footprint of the 55″ TV stand: 10.2″ x 18.1″

Sony X850D Movies

Because of its low contrast, the Sony X850D won't look its best when playing dark scenes in a dark room. As soon as you have some lights on, though, the X850D looks sharp, with decent color. It will play movies smoothly, without judder, from any source. HDR has seen a small improvement over last year, but without a local dimming feature, the X850D still won't be the best option for HDR.

The X850D doesn't produce deep blacks, although its screen uniformity is good. If watched in a dark room, blacks might appear a little grayish. Unfortunately, the X850D doesn't support local dimming or 3D.

HDR on the X850D is slightly improved is comparison with last year's X850D, mainly because the TV can get brighter. Unfortunately, because it is edge-lit and doesn't have a full-array backlight, those looking for a great HDR experience will be left wanting more. The X850D has a 10 bit panel and will be able to render good shadow details. Unfortunately, no improvement has been made to its wide color gamut coverage.

Lowest input lag is achieved under ‘Game’ picture mode. The ‘Clearness’ setting under ‘Motionflow’ can be used to clarify action some more and won’t increase the input lag (although it does darken the screen). Input lag also stays low enough for some slower games when image interpolation is turned on, which is something that can’t be said for most TVs.

Most resolutions are accepted. To get chroma 4:4:4, select ‘Game’ or ‘Graphics’ picture mode. For 4k @ 60Hz @ 4:4:4, you also need to set the HDMI input to ‘Enhanced format’ (under ‘External inputs’ menu). Just like with last year’s Sony TVs, 1080p @ 120Hz produces little artifacts (lines), but this shouldn’t be too bothersome while gaming. The ‘Graphics’ picture mode has fewer of these little artifacts.

Screen Finish

What it is:

Type of coating on the screen.

When it matters:

Bright objects in the direct reflection path (for example, opposite the TV).

Good value:

Glossy is good for ambient light, but not for direct reflections.

:
Semi-gloss

Bright objects reflected on the screen have rainbows around them. Reflections aren’t going to be a big problem as long as there aren’t too many lights in the room.

What it is:

Type of LCD technology used by the TV.

This is an IPS TV. Therefore, it has a wide viewing angle that is good for seating on the sides of the TV. Color saturation and contrast will stay good unless the TV is being viewed from wide angles.

The sound of the X850D, like that of most other TVs, is bad. It doesn't have a lot of bass and is distorted at high volumes. An external sound system like a sound bar would be a good investment to complement the X850D.

Decent frequency response. However, the low-end cutoff of 143Hz is rather high, even for a TV; this TV doesn’t produce a lot of bass. It doesn’t get very loud either, and pumping may be present at higher volumes.

This distortion pattern seems to be typical of Sony TVs: Good results at lower volumes, and then a big jump in harmonic distortion near the maximum loudness limit of the TV.

Software and Inputs

Sony X850D Smart TV

Smart OS: Android

Not much has changed from Sony's Android TV smart platform from last year, which isn't such a bad thing, though some improvements would have been nice. It still feels like Sony uses a bunch of different interfaces thrown together into one. The content and apps are there, though, and that is what really matters. The interface is faster, too. As for the TV's inputs, you probably won't need more. Just make sure you have enough space in your setup to hide the huge power brick.

Apps

All the major apps are available, including a web browser, YouTube, Netflix, Amazon Video, HBO Go and more.

Differences between Sizes and Variants

We reviewed the 55" (Sony XBR-55X850D). It has an IPS panel.

Update: The 65" is also IPS, so our review is also valid for that one.

As an interesting note, the 55" shares a panel very similar to the 2016 LG 55UH8500 that we reviewed a few weeks ago. The response time measurements are almost the same, as well as the contrast ratio (around 1200:1, which is very good for an IPS).

Top row, from left: Sony X850C (XBR55X850C), Sony X850D (XBR55X850D), Vizio P Series 2016 (P65-C1). Bottom: Sony X930D (XBR55X930D), Samsung KS8000 (UN55KS8000). Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

Compared to other TVs, the Sony X850D is a good choice for wide living rooms with seating on the side of the TV. If the main viewing position is directly in front of the TV, there are better alternatives.

Sony X930D

55" 65"

Amazon

CHECK PRICE
Right

The Sony X930D is better for watching movies in the dark, has the edge for HDR and offers 3D. It also is better in a living room because it has less reflections and can get brighter. The X850D is better for video games and maintains a better picture when viewed from the side which is good for a wide room.

8.2

Samsung KS8000

For most people, the Samsung KS8000 is a better choice. It is superior for watching movies in the dark as well as with HDR content. It also performs well in most living room since it can get bright enough to counter most of the screen reflections. The X850D maintains a better picture quality when viewed from the side and is slightly better for sports.

8.2

Vizio P Series 2016

50" 55" 65" 75"

Best Buy

CHECK PRICE
Right

From directly in front, the Vizio P has a better picture quality as long as the content being watched is of good quality. It is even truer if the TV is being watched in the dark. HDR is also superior on the Vizio P. Pick the X850D only if what you watch a lot of low quality content such as cable TV, DVDs and streaming and that you insist to keep a reasonable picture quality when viewing the TV from the side. For most though, the Vizio P is a better choice.

7.5

Sony X850C

55" 65" 75"

Amazon

CHECK PRICE
Right

The previous year iteration, Sony X850C, is still better for watching the TV in the dark but doesn’t offer as good quality for sports, HDR and video games. Get the X850C only if you watch regular movies the most and don’t care about the picture quality when viewed from the side of the TV.

Conclusion

Amazon

CHECK PRICE
Right

The Sony X850D offers good picture quality as long as it is watched in a room with some ambient light. Because of how well it handles motion, it will be a good pick for watching sports and playing video games. Its wide viewing angle will also ensure good picture quality for everyone in the living room. Unfortunately, those looking for good HDR implementation won’t be fully satisfied with this TV.
