The Sony X850G is a good 4k TV with an IPS panel. It delivers decent overall picture quality, but has a very low contrast ratio and bad black uniformity, so it isn't a great choice for a dark room. This TV has great peak brightness and excellent reflection handling, so it has no trouble overcoming glare in a bright room, and the image remains accurate when viewed at an angle. It's a great TV for gaming, as it has outstanding low input lag, the lowest of any recent Sony TV, and an excellent response time.

Note: The 85" model has a VA panel, and likely looks much better in a dark room, but has worse viewing angles.

Market Context

The Sony X850G is the direct replacement for the 2018 Sony X850F. It sits between the X800G and the X900F in the 2019 lineup, and is more of a budget model for Sony. Its main competitors are IPS TVs like the Sony X800G, the LG UM7300, and VA TVs, like the Samsung RU8000, TCL 6 Series/R617, and the Hisense H8F.

8.5

Design

Curved : No

The Sony X850G has a very basic design, and it looks very similar to the X850F. The body is very thin, but is almost entirely made of plastic and feels a bit cheap in some places. Because this TV has two feet instead of a center stand, it requires a larger table.

Stand

The stand supports the TV well, and there is very little wobble. The feet themselves are quite small, but they require a fairly large table, as they are near the ends of the TV.

Footprint of the 65" stand: 41.2" x 12.5".

Back
Wall Mount : VESA 300x300

The back of the TV is very basic, and is made of plastic. The panels have some flex to them, but we don't expect this to cause any issues. The back of the feet can be used for very basic cable management.

Borders
Borders : 0.55" (1.4 cm)

The borders are of average thickness and don't stand out much.

Thickness
Max Thickness : 1.89" (4.8 cm)

This TV is very thin, much thinner than the X800G, and it looks great wall-mounted.

7.5 Build Quality

Overall, the X850G has decent build quality. The body of the TV is almost entirely made of plastic, and there's some flex to the back panel, but there are no obvious issues or areas of concern.

7.2

Picture Quality

The Sony X850G delivers decent overall picture quality. Like most IPS displays, it has decent viewing angles, but doesn't look great in a dark room, as it has a disappointing contrast ratio, bad black uniformity, and it doesn't have a local dimming feature. This TV looks great in a bright room, though, as it has great peak brightness in SDR and excellent reflection handling. It can display a wide color gamut, but has disappointing color volume. There is very little banding in areas of similar color.

5.6 Contrast
Native Contrast

The Sony X850G has a disappointing contrast ratio, worse than any recent TV, including the X800G. Blacks look gray, especially when watching TV in a dark room.

Note: The 85" model (XBR-85X850G) has a VA panel, and likely has much better contrast.

Great peak brightness in SDR, with no variation in brightness with different content, which is great. We measured the peak brightness after calibration, with the 'Custom' Picture Mode and the 'Expert 1' Color temperature.

Unfortunately, there are no brighter picture modes. Enabling Adv. contrast enhancer increases the peak brightness a tiny bit, but not enough to make a noticeable difference.

Decent peak brightness in HDR. Small bright highlights in some scenes stand out, but not enough to show off the content creator's intent.

We measured the peak brightness with no calibration settings, with the 'Cinema' Picture Mode and the Color temperature set to 'Expert 2'.

Unlike most TVs, these settings are the most accurate and the brightest. The 'Vivid' picture mode has a lower peak brightness.

Decent viewing angles. At very wide angles the image starts to appear washed out, but colors only shift at extremely wide angles. Colors appear washed out at moderate angles, but this shouldn't be an issue for most people.

Note: The 85" model (XBR-85X850G) has a VA panel, and likely has a worse viewing angle.

After calibration, the X850G has excellent accuracy, but it's a bit worse than most TVs. There are still inaccuracies in some colors, especially reds, that some people might notice. Gamma follows much closer to 2.2, and the white balance is nearly perfect.

You can see our recommended settings here.

8.0 480p Input

480p content, like DVD movies, looks great, with no obvious upscaling artifacts.

8.0 720p Input

720p content, including cable TV stations, looks great, with no significant issues.

9.0 1080p Input

1080p content, including Blu-rays, looks almost as good as native 4k content. When the 'Graphics' Picture Mode is used with 1080p content, the TV switches to nearest-neighbor upscaling, which some people prefer for computer use.

10 4k Input

4k content is displayed perfectly, with no dithering or sub-pixel artifacts.

The X850G can display a wide color gamut, and has great coverage of the DCI-P3 color gamut used by most 4k UHD Blu-rays. The EOTF follows the PQ Curve closely for the most part, but dark scenes are over-brightened. The TV starts tone mapping near its peak brightness, but unfortunately, whites mastered above about 1500 cd/m² are clipped, causing a loss of some bright details.

The PC Mode EOTF is nearly identical, but some scenes are over-brightened.

If you find HDR content too dark, setting the Color Temp to 'Expert 2', Contrast to 'Max', Gamma to 'Max', and Adv. contrast enhancer to 'High' results in a noticeably brighter image, as shown in this EOTF. Unfortunately, the peak brightness remains unchanged, and whites are clipped above about 400 cd/m².

Mediocre color volume. It's limited by the low contrast ratio, and the limits of the color gamut it can display.

Note: The 85" model (XBR-85X850G) has a VA panel, and likely has slightly better color volume.

Although some IPS panels can suffer from temporary image retention, this doesn't appear to be permanent, as seen in our long-term test.

Pixels

Like the X850F, this TV uses an IPS panel.

8.4

Motion

The Sony X850G has great motion handling. It has an excellent response time, but there is some noticeable overshoot in most transitions, which can be distracting. The backlight is flicker-free, but there it has an optional black frame insertion feature, which introduces 120Hz flicker in order to improve the appearance of motion. This TV has a native 120Hz panel, but it can only display 120Hz content through motion interpolation, and it doesn't support any variable refresh rate technologies, like FreeSync.

This TV has an optional black frame insertion feature that improves the appearance of motion, but it can only flicker at 120Hz, which isn't ideal as it causes noticeable duplications with 60Hz content.

To enable this feature on the X850G, set Motionflow to 'Custom', and adjust the Clearness setting to your liking.

10 Motion Interpolation
Motion Interpolation (30 fps)
:
Yes
Motion Interpolation (60 fps)
:
Yes

Even though this TV only accepts 60Hz signals, it can interpolate lower frame rate content to increase the frame rate as high as 120Hz. Like most TVs, there are some artifacts with higher settings, and this introduces an effect known as the Soap Opera Effect, which may bother some people.

See our recommended settings here.

7.4 Stutter
Frame Hold Time @ 24 fps
:
28.4 ms
Frame Hold Time @ 60 fps

This TV can remove judder from all sources, which is great. Movies played from 24p sources, like a Blu-ray player, are always judder-free. When watching movies played from a 60p/i source, like a cable box, Motionflow has to be set to 'Custom', with both sliders set to 'Min' and CineMotion set to 'Auto'.

Inputs

The Sony X850G has outstanding low input lag in 'Game' mode, the best we've seen on any recent Sony TV. It can display chroma 4:4:4 properly from a computer, which is important for clear text, but it doesn't support 1440p inputs. Despite the 120Hz panel, it doesn't accept a 120Hz signal. Like most other Sony TVs, it supports HDR10 and Dolby Vision, but not HDR10+.

6.0

Sound Quality

This TV has mediocre sound quality. It has a decent frequency response, but the low-frequency extension (LFE) is high, so the bass has no thump or rumble, and only a bit of punch. Dialog is clear, but it lacks a bit of airiness due to the dip around 10kHz. Like the Sony X950G, this TV has an additional pair of speakers at the top, which are supposed to help with sound positioning. Unfortunately, we don't currently test for this. For better sound, a dedicated speaker system or soundbar is recommended.

The Sony X850G has a decent frequency response. The low-frequency extension (LFE) is high, so there is no thump or rumble to its bass, and it has only a bit of punch. Above the LFE, the frequency response is more balanced, resulting in clear dialog, but it lacks a bit of airiness due to the dip around 10kHz. This TV can get pretty loud, but it does produce a bit of pumping at peak volume.

Smart Features

Smart OS : Android TV
Version : 8.0

The Sony X850G runs the latest version of Android TV. The interface is well-organized and easy to use, and it's very smooth. There is a huge selection of apps from the built-in Google Play Store, and almost all of the most common streaming apps are pre-installed. Unfortunately, there are ads in the interface, and they normally can't be disabled. This TV comes with a new version of Sony's traditional remote, similar to the X950G. The new remote now fully supports Bluetooth connectivity, and it no longer requires direct line-of-sight to the TV for most functions.

Differences between Sizes and Variants

We tested the 65" X850G (XBR-65X850G), and we expect our results to be valid for the 55" (XBR-55X850G) and 75" (XBR-75X850G) models as well. The 85" (XBR-85X850G) has a VA panel, so some results will be different, including contrast, black uniformity, and viewing angles.

If someone comes across a different type of panel or if their Sony X850G 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.

7.8 Mixed Usage
Overall, the X850G is a good TV for most uses. It's best suited for a bright room, a wide seating area, or for watching sports or TV shows with a group of friends. It has great gaming performance, with low input lag and a fast response time. Unfortunately, it isn't great for watching movies or HDR content in a dark room.
6.3 Movies
This is a mediocre TV for watching movies in a dark room. It has disappointing contrast and bad black uniformity, so blacks are gray and cloudy, and there is no local dimming feature. 1080p content, like Blu-rays, is upscaled well, and looks almost as good as native 4k.
8.4 TV Shows
The X850G is a great TV for watching TV shows in a bright room. It has great peak brightness and excellent reflection handling, so glare shouldn't be an issue in most rooms. The image remains accurate when viewed at an angle, so it's great if you like to walk around with the TV on. There is a huge selection of apps available, covering the vast majority of the most popular streaming services.
8.3 Sports
This is a great TV for watching sports in a bright room with a group of friends. It has wide viewing angles, great peak brightness, and excellent reflection handling. It has an excellent response time, so fast-moving objects look clear, with very little blur.
8.4 Video Games
Overall, the X850G is a great TV for playing video games. It has excellent low input lag for a responsive gaming experience, and it has an excellent response time, so there is very little blur behind fast-moving objects. 1080p games are upscaled well, and look almost as good as native 4k content. Unfortunately, although this TV has a 120Hz panel, it doesn't accept 120Hz input, like 1080p @ 120Hz.
6.3 HDR Movies
The X850G is a mediocre TV for watching the latest HDR movies. It has a disappointing contrast ratio, no local dimming feature, and bad black uniformity. HDR peak brightness is decent, so small bright objects stand out in HDR, but they aren't as bright as they should be.
7.8 HDR Gaming
This is a good TV for HDR gaming, but mainly due to the great gaming performance, as HDR doesn't look great in a dark room. It has outstanding low input lag and a fast response time, but disappointing contrast, no local dimming, and bad black uniformity.
8.5 PC Monitor
The Sony X850G is an excellent TV for use as a PC monitor. It has excellent low input lag, an extremely fast response time, and decent viewing angles. It can display chroma 4:4:4 properly, and in 'Graphics' mode it supports nearest neighbor upscaling, which some people prefer.
