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. Unfortunately, it also doesn't have a local dimming feature to help with black levels. On the bright side, this TV has great peak brightness and excellent reflection handling, so it should have 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 though we haven't tested it, we'd expect it to look much better in a dark room, but have worse viewing angles.
Our Verdict
The Sony X850G is a good TV for mixed usage. It's a great choice for sports, TV shows, or video games thanks to its fairly wide viewing angles and fast response time. Unfortunately, due to its IPS panel, its contrast and black uniformity are poor, so it may not be the best for watching movies in dark rooms, as blacks will appear gray and cloudy. On the bright side, it can get decently bright for HDR content, and it has a fairly wide color gamut, so HDR content should look good, though it may not pop quite as much as the creator intended.

The Sony X850G is a mediocre TV for watching movies. Due to its IPS panel, it has a disappointing contrast ratio, and in dark rooms blacks will appear gray and cloudy. It's worth noting that the 85" model of this TV uses a VA panel, so we'd expect it to perform better in this regard. It also doesn't have a local dimming feature to help with its black levels.
The Sony X850G is a great TV for watching TV shows. It has excellent reflection handling so even in bright rooms, glare shouldn't be too much of an issue. The viewing angles are also quite decent, so you should still get a fairly accurate image if you watch TV from the side, or while walking around.
The Sony X850G is a great TV for watching sports. Thanks to its IPS panel, it has decently wide viewing angles, so a large group of friends can all watch the game at the same time and still get the same accurate image. It also has an excellent fast response time, so fast-moving objects should look clear and have very little blur.
The Sony X850G is an impressive TV for playing video games. It has a very fast response time, so motion should look clear with very little blur, and its superbly low input lag means that you shouldn't notice any delay. Unfortunately, while this TV has a 120Hz panel, it doesn't accept a 120Hz input over HDMI, and it doesn't support any variable refresh rate technologies, like FreeSync.
The Sony X850G is mediocre for watching HDR movies. Its poor contrast and black uniformity means that while watching movies in a dark room, blacks will appear gray and cloudy. It also can't get quite bright enough for HDR content to really pop. On the bright side, this TV has a fairly wide color gamut, which will help HDR content look closer to the way the creator intended.
The Sony X850G is a good TV for HDR gaming thanks to its great gaming performance. Unfortunately, its HDR performance is only acceptable, partly due to the fact that the screen can't get quite bright enough for HDR to really shine. On the bright side, its fairly wide color gamut will help HDR content look closer to the way the creator intended.
The Sony X850G is an excellent TV to use as a PC monitor. It can properly display chroma 4:4:4 when in 'Game' or 'Graphics' mode, which is important for text to appear clear when using a TV as a monitor. It has extremely low input lag and fast response time, which is great if you game from your PC, and when in 'Graphics' mode, the TV switches to nearest-neighbor upscaling, which prevents upscaled content from looking too soft.

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.
| Size | US Model | Full Model Code | Alternative Name | EU Model | Notes |
| 55" | XBR55X850G | XBR55X850G/C | XBR-55X850G | KD-55XG8* | |
| 65" | XBR65X850G | XBR65X850G/C | XBR-65X850G | KD-65XG8* | |
| 75" | XBR75X850G | XBR75X850G/C | XBR-75X850G | KD-75XG8* | |
| 85" | XBR85X850G | XBR85X850G/C | XBR-85X850G | KD-85XG8* | VA panel |
Note: The European model is available in multiple variants, as the XG8505, XG8596, and XG8796. We don't know if there is any difference between them.
The X850G we reviewed was manufactured in April 2019.
Compared To Other TVs
The X850G is a basic 4k TV with decent performance. See our recommendations for the best TVs, the best smart TVs, and the best sounding TVs.
Although the 2019 Sony X850G is supposed to be a higher-end model over the 2020 Sony X800H, the X850G is only slightly better. Both have IPS panels and the X800H has much better viewing angles, black uniformity, and contrast ratio, although the X850G has better gray uniformity, quicker response time, and a more effective black frame insertion feature to help reduce motion blur. Both can get equally as bright, but the X850G handles reflections much better, so it's better suited for a bright room. For a cheaper price, the X800H compares well to a more expensive X850G.
There are very few differences between the Sony X850F and the Sony X850G. The 2019 X850G has much lower input lag, and it supports eARC. Other than that, these two TVs perform very similarly.
The Sony X900F and the Sony X850G use different panel types, each with their own strengths and weaknesses, but the X900F is much better overall. The X900F uses a VA panel, and delivers much better dark-room performance, and it has a decent local dimming feature. The X900F has a faster response time, and supports 1080p and 1440p @ 120Hz inputs. The X850G doesn't look as good in a dark room, but it has a better viewing angle. The 85" X850G has a VA panel, though, and likely performs closer to the X900F.
The Sony X850G is better than the Sony X800G. The X850G has better gray uniformity, better reflection handling, and much lower input lag, for a more responsive gaming experience. The X850G can remove judder from all sources, and it can interpolate motion up to 120Hz.
The Sony X950G and the Sony X850G use different panel types, each with their own strengths and weaknesses, but overall, the X950G is much better than the X850G. The X950G looks much better in a dark room, but the image degrades when viewed at an angle compared to the X850G. The 85" X850G has a VA panel, and likely performs closer to the X950G, but still isn't as good.
The Samsung RU8000 and the Sony X850G use different panel types, each with advantages and disadvantages. The Samsung has much better dark room performance thanks to its VA panel, but the image loses accuracy when viewed from the side. It also has a lower input lag and is equipped with gaming features like VRR support that should please gamers. The Sony is a better choice if you regularly watch TV from the side and can handle reflections a little better.
The Samsung Q60/Q60R QLED performs similarly to the Sony X850G. The Q60 has much better contrast and black levels thanks to its VA panel; it has a faster response time, and an easier-to-use smart interface. On the other hand, the Sony X850G has much wider viewing angles thanks to its IPS panel, looks and feels more premium and better-built, and has a slightly higher peak brightness.
The Samsung Q70/Q70R QLED and the Sony X850G use different panel technologies, each with advantages and disadvantages. The Q70R uses a VA panel with a much higher contrast ratio and black uniformity to deliver a superior dark room performance. The Q70R is also equipped with native FreeSync, which should please gamers. The X850G, on the other hand, uses an IPS panel, so it has much wider viewing angles and can handle reflections better when in a room with many lights.
The Sony X850G and LG B8 OLED use different panel technologies, each with advantages and disadvantages. The Sony has an IPS panel and can get much brighter than the LG. The LG, on the other hand, has much better dark room performance thanks to the perfect blacks of the OLED panel. The LG has a faster response time and delivers crisp motion but with more stutter. The Sony is immune to the risk of burn-in, which OLEDs have with cumulative prolonged exposure to static content.
The Sony X850G is a bit better than the LG UM7300. The X850G is a lot brighter but has worse black uniformity. The backlight of the X850G is flicker-free, and it has an optional black frame insertion feature. Other than that, these two TVs perform almost identically.
The Sony X850G is marginally better than the LG SM8600. The Sony can get much brighter, has better gray uniformity, better viewing angles, and slightly better motion handling. On the other hand, the LG has better contrast, local dimming, and a wider color gamut.
The LG SM9000 is a better TV for most uses than the Sony X850G. The LG has local dimming, more accurate colors out-of-the-box, a wider color gamut, and an easier-to-use smart interface. On the other hand, the Sony looks better-built, can get much brighter, has much better gray uniformity (resulting in less dirty screen effect), and better reflection handling.
The LG UM8070 and the Sony X850G have different panels, each with its advantages and disadvantages. The LG delivers deeper blacks in a dark room thanks to its higher contrast ratio and better black uniformity due to its VA panel. The Sony has an IPS panel and the image remains accurate for wider viewing angles. The Sony has better gray uniformity, which will please sports fans, and it's more suitable for a brighter room as it can get brighter and can handle reflections better. The UM8070, on the other hand, has a faster response time and delivers crisper motion in fast-moving content.
Test Results
The Sony X850G is the direct replacement of the 2018 Sony X850F. It sits between the Sony X800G and the Sony 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. The 2021 model, the Sony X85J, uses a VA panel instead of an IPS.
This TV 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. The TV uses two feet instead of a center stand, so you may need a slightly larger table, depending on the size of your TV.
The stand supports the TV well, and there's 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".
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.
The borders are of average thickness and don't stand out much.
This TV is very thin, much thinner than the Sony X800G, and it looks great wall-mounted.
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.
This TV has a disappointing contrast ratio, worse than any recent TV, including the Sony X800G. Blacks look gray, especially when watching TV in a dark room. If you're looking for a Sony TV with an IPS panel but improved contrast ratio, then check out the Sony X800H.
Note: The 85" model (XBR-85X850G) has a VA panel, and though we haven't tested it, we'd expect its contrast to be much better. The 2021 model of this TV, the Sony X85J, uses a VA panel and has much better contrast as well.
This TV doesn't have a local dimming feature. The above video is for reference only. If you want local dimming, then check out the Sony X900H.
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.
Very good gray uniformity. There isn't much variation in the center of the screen, but there's noticeable vignetting, and the sides of the screen are a bit darker. In near-dark scenes, the uniformity is significantly better.
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, so while we haven't tested it, we'd expected it to have worse viewing angles.
This TV has bad black uniformity, worse than the X800G. There is significant clouding throughout the entire screen, and the LEDs can be seen bleeding through the bottom edge.
Note: Though we haven't tested it, the 85" model (XBR-85X850G) has a VA panel, and we'd expect its black uniformity to be significantly better.
Excellent reflection handling. There's still some noticeable glare, as the screen finish isn't able to completely diffuse bright lights, but in most rooms there shouldn't be any issues.
With our pre-calibration settings, this TV has mediocre accuracy. There are noticeable errors in many colors, as well as brighter shades of gray. Gamma is too low, tracking closer to 2.0, so most scenes are too bright, and the color temperature is a bit too warm.
After calibration, this TV has excellent accuracy, but it's still 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.
480p content, like DVD movies, looks great, with no obvious upscaling artifacts.
720p content, including cable TV stations, looks great, with no significant issues.
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.
4k content is displayed perfectly, with no dithering or sub-pixel artifacts.
The Sony 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.
The color volume of this TV is mediocre, as it's limited by its low contrast ratio, and is slightly restricted by its color gamut.
Note: Though we haven't tested it, the 85" model (XBR-85X850G) has a VA panel, so we'd expect it to have slightly better color volume.
The Sony X850G has excellent gradient handling. There's some slight banding in all shades, but this shouldn't be noticeable with most content.
There's only minor temporary image retention immediately after displaying our high-contrast static test image for 10 minutes, and it disappears almost immediately.
Although some IPS panels can suffer from temporary image retention, this doesn't appear to be permanent, as seen in our long-term test.
This TV has an excellent response time, but unfortunately, there's noticeable overshoot in most transitions.
The backlight is completely flicker-free, which is great. There is some noise at low backlight levels, but this isn't noticeable, and the backlight never turns completely off.
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.
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.
The relatively fast response time of this TV results in some noticeable stutter when watching 24p movies. This is especially noticeable with slow, panning shots.
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'.
The Sony X850G has a native 120Hz panel, but doesn't support any advanced variable refresh rate technologies, like FreeSync.
This TV has outstanding low input lag, better than any recent Sony TV we've tested, including the higher-end Sony X950G.
The Sony X850G has a native 120Hz panel, but it can't display a 120Hz signal from 1080p or 1440p sources. It can display chroma 4:4:4 properly, which is important for clear text when connected to a PC, but only in the 'Game' or 'Graphics' picture mode. Like many other Sony TVs, when in the 'Graphics' mode, the TV switches to nearest-neighbor upscaling when sent a 1080p signal.
The Sony X850G supports HDR10 and Dolby Vision but doesn't support HDR10+.
Update 01/07/2020: DTS passthrough is working over a standard ARC connection as well as optical. It was discovered that system sounds must be disabled for it to work.
The Sony X850G supports eARC.
The speakers on this TV have an alright frequency response. The low-frequency extension (LFE) is high, so there's 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.
This TV has poor distortion performance. The total amount of harmonic distortion is very high, and it increases significantly higher at maximum volume.
Update 07/07/2020: The operating system has been updated to Android 9.0. There are some minor changes to the user interface, and support has been added for Apple AirPlay and Dolby Atmos via the TV's speakers.
The interface is very well-organized and easy to use. It's also very smooth, but we experienced a few crashes during our testing.
Unfortunately, there are ads and suggested content on this TV. The suggested content can be disabled, but there's no direct option to disable the ads. There's a workaround, though, as described here.
The Android TV interface has a massive selection of apps through the included Google Play Store. The built-in apps work great, and cover the majority of the most common streaming services.
The included remote is very similar to the one included with the Sony X950G, but with a black finish instead of silver. It's the upgraded 2019 Sony remote with Bluetooth connectivity, so you don't need direct line-of-sight to the TV for most functions. The remote also has a built-in microphone, and once it's been paired to the TV it can be used for voice control.
