Good value: IPS maintains good color accuracy at an angle, but has a poor contrast ratio from in front. VA has great picture quality in front, but loses saturation at an angle. OLED maintains good color accuracy at an angle without any of the other issues seen with IPS and VA, as they keep good brightness and contrast at an angle.
:
IPS (except 85")
Resolution : 4k

The Sony X850F is a good 4k TV with an IPS panel. It can get bright to overcome glare and handles reflection well in a bright room but it has a very low contrast ratio so blacks appear gray when viewed in a dark room. The picture quality is decent but remains accurate when viewed at an angle which is good for those with wide seating. It also has a fast response time, which is great for watching fast-paced content. Unfortunately, Android TV isn't as streamlined or intuitive as other platforms.

Sony X850F Design Picture
Curved : No

The design of the Sony 2018 X850F is great. The legs, while similar to the X900F are unlike any Sony we have reviewed recently. They are wide-set and require a larger table, but there should be no issues placing a soundbar between them. There is only basic cable management at the back, similar to the X900F, but not as good as the X930E which includes routing through the back panel. The bottom edge of the TV gets a little warm to the touch. Despite being almost entirely made of plastic, the TV feels well constructed.

Stand
Sony X850F Stand Picture

The stand on the X850F is unlike any other Sony TV we have reviewed. It is similar to the stand on the Samsung MU6100. It is made entirely of plastic with an aluminum finish. On our 65" model, we found them to cause the TV to wobble if it is knocked.

The footprint of the 65" TV stand: 12.0" x 43.4"

Back
Sony X850F Back Picture
Wall Mount : Vesa 300x300

Similar to the X850E, the back of the TV is quite basic. Similar to the X900F there is only very basic cable management through the legs of the TV. The back is almost identical to the X900F.

Borders
Sony X850F Borders Picture
Borders : 0.39" (1.0 cm)

The borders of the TV look good. While slightly thicker than the 55" X900F they are still quite thin.

Thickness
Sony X850F Thickness Picture
Max Thickness : 2.13" (5.4 cm)

The Sony XBR65X850F has more of a uniform thickness than the X900F. It won't stick out from the wall much when mounted.

The bottom edge of the TV gets warm to the touch due to the edge light LEDs. There are also a few places along the back that get warm to the touch, but this should't be an issue.

7.5 Build Quality
Sony X850F Build quality picture

The X850F feels well constructed, despite being made almost entirely of plastic. There are no obvious gaps or issues. The tabs along the back of the legs for cable management are just bent plastic. While it hasn't caused any issues for us, this could break with repeated flexing.

The picture quality of the Sony X850F is decent. It has no local dimming and a disappointing contrast ratio. It also has a good SDR brightness and an average HDR brightness, but the TV is not bright enough to fully appreciate HDR content. It has a better than average gray uniformity, but a disappointing black uniformity with a lot of clouding. The TV has a good viewing angle and is well suited to a large room. Reflections are less problematic than with the X850E. Out-of-the-box, color accuracy is average, and most of it is correctable through calibration. The color gamut is good but can't produce overly saturated greens or deep, dark colors.

Disappointing contrast ratio on the X850F. It has an IPS type panel similar to the X850D. Dark scenes will not look their best especially when playing in a dark room.

Sony X850F EOTF

The HDR color gamut of the X850F is decent, although Rec 2020 coverage is limited. The TV has difficulty producing deeply saturated greens especially. Most scenes won't have overly saturated colors, but in very colorful scenes such as a sunset or an ocean scene the TV's limited color gamut will be noticeable.

The HDR EOTF in the 'Cinema Pro' picture mode follows the target PQ curve fairly well until it rolls off at the TV's peak brightness. The EOTFs in 'Game' and 'PC' mode are very similar to that of 'Cinema Pro', which is good.

Pixels

Motion looks great on the Sony X850F. During sports and video games the TV's very fast response time reduces ghosting during motion, which is great. When watching movies and TV shows, the TV can show this motion with minimal stutter and can use optional 120 Hz soap opera effect if you want even smoother motion. And in all content, the TV's backlight has no visible flicker, which makes motion look smoother, unlike the flickering backlights of most TVs.

Great fast response time, good enough for even fast-moving content like sports.

The X850F has no visible flicker in its backlight, which makes motion appear smooth. This is, unfortunately, a rare thing in TVs; many TVs have 120 Hz PWM flicker, like the LG SJ9500 and Samsung MU8000, which causes duplications during motion (as seen in this MU8000 photo).

The X850F has an optional BFI mode that adds flicker to make motion look more clear. Unfortunately, this flicker is limited to 120 Hz, which causes duplications in 60 fps motion, as seen in the photo; 60 Hz flicker like that of the Samsung NU8000 would be better. The X850F's flicker is activated by setting 'Motionflow' to 'Custom' and increasing the 'Clearness' slider. The X850F does not have the new 'X-Motion Clarity' feature of the X900F, so adding flicker will decrease the TV's brightness.

The Sony X850F supports all the common input signals, including HDR. It has good low input lag for 4k and 1080p signals, so there will be no issues for all but the most serious gamers. It supports chroma 4:4:4 and 1080p @ 120 Hz, which is good for use as a PC monitor.

Like all other Sony TVs we have reviewed, only HDMI ports 2 and 3 support full bandwidth, but HDMI 3 is also the audio return channel. If you have a receiver that supports ARC and more than 1 device which requires the full bandwidth of HDMI then you might have some issues connecting all of your devices.

The X850F supports all common input signals. Chroma 4:4:4 is supported in 'Game' or 'Graphics' mode. Only HDMI inputs 2 or 3 support 4k @ 60Hz @ chroma 4:4:4 or 4:2:2, and only when 'HDMI Enhanced Format' is enabled.

When in 'Graphics' mode upscaling is done by nearest neighbour when in 1080p @ 60 Hz. When sending a 120 Hz signal there is no nearest neighbour upscaling.

Score components:

The sound quality of the Sony X850F is mediocre. This TV does get loud enough for most use cases and does have a well-balanced sound in the mid and treble ranges, which is important for producing clear and natural dialogs. However, its bass is lacking a lot of punch and rumble, doesn't have a self-calibrating system to EQ the room, and produces a lot of harmonic distortion under maximum load. For a better sound reproduction, getting a dedicated soundbar is recommended.

The X850F has a mediocre frequency response. The LFE (low-frequency extension) of 120Hz is inadequate for creating the punch and rumble common to bass-heavy music and movie sound effects. The frequency response above the TV's LFE is quite well-balanced, but since it doesn't have a self-calibrating system, it wasn't able to remove our lab's room modes. This shows as a build-up of energy in the high-bass/low-mid region. On the upside, the TV does get loud enough for most use cases, and doesn't produce too much pumping and compression artifacts under heavy loads.

The harmonic distortion performance of the X850F is sub-par. At low and moderate volumes the X850F has a good THD performance. However, like most other Sony TVs we have measured, their THD jumps to very high levels under maximum load. But this will be rarely audible since most users won't need to set their TVs volume to max, and harmonic distortion is not as audible with real-life content (as opposed to with a test signal).

The Sony X850F uses the same Android TV found in other Sony TVs we have reviewed, like the X900F. The interface is quite crowded with the numerous built-in apps, and thousands more available on the included Google Play Store. The interface is functional, but there is significant lag and the animations are choppy. The included remote gives quick access to Google Assistant. You can search for apps or content by voice, and it works well with basic commands such as "open Netflix", or "What is the weather like in New York?".

The interface works well and is intuitive, but purists will find it too crowded.

The X850F includes the same remote as the X850E. It has more buttons than most remotes and is quite large, but with good usability. Buttons are easy to find and it doesn't take long to access most basic functions of the TV.

    Differences between Sizes and Variants

    We tested the 65" (XBR65X850F). For the most part, we expect our review to be valid for the 75" (XBR75X850F).

    We haven't tested the 85" (XBR85X850F), but it likely uses a VA panel (similar to the 85" X850D) with a high native contrast ratio producing deeper blacks, but the image degrades when viewed at an angle.

    The European variant of the TV is also known as the XF85 or XF87 and comes in a different range of sizes as shown below. We have received reports that the 49" variant of the X850F available in Europe has a VA panel, as shown in this photo of the pixels. This size likely has better dark room performance but a narrow viewing angle.

    If someone comes across a different type of panel or if their Sony X850F 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.

    Compared to other TVs

    Sony X850F Group Shot Picture

    The Sony X850F is a good pick for a bright room with wide seating as the low native contrast ratio makes blacks appear gray in a dark room, but the image remains accurate when viewed at an angle. See our picks below for how it compares to the competition.

    Sony X850E
    65" 75"

    The Sony X850E is the precursor to the X850F available in 65" and 75" sizes. The 65" model has a VA panel, so blacks appear deep in a dark room but the image degrades when viewed at an angle. The 75" model has different performance which is more similar to the X850F we tested. For a dark room and if you want to sit directly in front of the TV, go with the X850E for the deeper blacks and better picture quality. For a bright room with wide seatings, we expect the 75" model of both TVs to be very similar, so you should go with whichever is cheaper.

    LG SJ8500
    55" 65"

    The SJ8500 is a 2017 model from LG with a low native contrast ratio so blooming is visible in a dark room but the image remains accurate when viewed at an angle. It is a good pick for watching sports or TV shows in a living room as the screen is good at handling reflections, and even those who sat off to the side get an accurate picture. It is also a bit better for gamers due to the very low input lag. Overall, it can't get as bright as the X850F to handle glare and doesn't have as much control over the motion but it also comes at a much lower price, so most people are better off saving the money and buying the SJ8500.

    Sony X900F
    49" 55" 65" 75" 85"

    The X900F is the next step up in Sony's 2018 lineup. It is better than the X850F, especially in a dark room due to the high native contrast ratio and decent local dimming support which improves dark scene performance. It also has better HDR capabilities, as it can produce brighter and more vivid highlights. Unfortunately, the image degrades when viewed at an angle, but for those with narrow seating, the X900F is a better choice.

    Samsung NU8000
    49" 55" 65" 75" 82"

    The Samsung NU8000 is a versatile 4k TV available in sizes from 49" up to 82".  It has good picture quality, and better dark room performance than the X850F due to the excellent native contrast and uniformity. Unfortunately, the image degrades when viewed at an angle so it is a worse fit for watching TV shows or sports in a wide room. For a bright room with wide seating go with the X850F, but for those who watch from directly in front, the NU8000 is a better choice.

    Great option for a monitor. Image remains accurate when viewed at an angle, which is great when viewing the edge of the screen from close up for PC use. The TV supports chroma 4:4:4 for clear text on all backgrounds, and it feels responsive due to low input lag and great motion handling.

    Why do you test the X850F in custom but the Samsung in Movie mode? It doesn’t seem like a fair comparison.
    We test each TV in whichever mode is closest to our target calibration settings. This varies between manufacturers but for Sony we almost always test in either 'Custom' or 'Cinema Pro', and for Samsung TVs we almost always test in 'Movie' mode. Although the names of the modes are very different, these are also the modes that allow the most setting customization.
