The Sony X900F is a great 4k TV with impressive picture quality, especially in a dark room due to the high native contrast ratio and full array local dimming support. The TV excels at HDR as it can produce bright, vivid highlights. Motion handling is also excellent due to the fast response time and ability to flicker the backlight to clear up motion. The only main negative is the narrow viewing angle, so the best image quality is reserved for those directly in front of the TV.
The design of the Sony 2018 X900F is great. It is quite different to the 'traditional' Sony aesthetics from the last few years, such as the X900E. The wide-set legs are the most noticeable difference, and do require a larger table but are designed so that the Sony soundbar can fit between them. There is basic cable management similar to the X900E down the back of the stand, but it isn't as good as the X930E which includes routing through the back panel. The build quality is very good and the TV feels solid.
The rear of the TV is quite basic, and is very similar to last year's model. There are two groups of inputs on the rear of the TV. One is inset and directed down, and can be difficult to access if the TV is placed close to the wall. The second group is directed out the side of the TV and provides easier access.
The TV has an average thickness when viewed from the side. It will stick out from the wall a bit more than some other TVs such as the X930E, but this isn't too much of an issue.
The X900F runs fairly cool, thanks to its local dimming saving power where peak brightness isn't needed. The TV has vents along the bottom edge and on the back near the top, which likely won't be blocked when the TV is wall mounted, which is good.
The Sony X900F has a very good picture quality. When set in a dark room, the deep black it can produce help greatly with dark scene reproduction. This is mostly due to the impressive contrast ratio, good black uniformity, and decent local dimming feature. When set in a brighter room, the TV is also very good since it got a great SDR peak brightness and the screen finish is great at dealing with reflection and glare. The gray uniformity is good and dirty screen effect is not visible while watching sports like football or ice hockey.
When it comes to the viewing angle, the performance of the Sony X900F is disappointing and as such, the best picture quality is relegated to a sweet spot right in front of the TV. Finally, HDR looks great and this is mostly due to the high HDR peak brightness, which when paired with the local dimming, can reproduce very bright specular highlights.
The native contrast ratio is excellent. When set in a dark room, it can display really deep blacks, making the TV a very good option if you have a dark home theater room.
When the local dimming is turned on, the contrast ratio on the checkerboard pattern goes up, but not by much since the zones are not small enough to have an impact on this pattern.
The full array local dimming of the Sony X900F is decent and better than most LED TVs. It is a small upgrade when compared to the 2017 X900E. The X900F performance is more similar to the 2017 Sony X930E when set side by side, although the X930E has slightly less abrupt transitions of the zones on movements.
Very similar performance to the Samsung Q8FN. The X900F has deeper black levels, but there is more visible blooming.
When set to 'High', the feature is very good at limiting blooming and keeping a good overall black level, but on some occasions, it may be a bit too aggressive, as small highlights can get dimmed on fast movements. Therefore, if you notice this behavior, you can set it the 'Medium', and it should behave more conservatively.
Great SDR peak brightness, good enough for even a bright room. The TV's local dimming does a good job of boosting bright sections of the screen when other sections are dimmer, shown by how the smaller window tests are brighter than the larger ones. Overall, this brightness is a marked improvement over last year's X900E, and is far better than the brightness of many competing TVs like the Samsung MU8000 and LG SJ8500, though still not as bright as last year's X930E.
Great HDR peak brightness; bright highlights in HDR content will be shown fairly bright, though not quite as bright as the 1000-4000 cd/m² they're intended to be. The TV's local dimming is able to boost highlights to be very bright, because the rest of the scene in HDR content is usually fairly dim when compared to SDR content, so the TV has more power budget for the hightlights. Overall the HDR brightness is better than last year's X900E.
The gray uniformity is good. The 50% gray uniformity looks good, and the issues are mostly situated near the edge and corners, which are darker than the center of the screen. Besides that, dirty screen effect is not problematic since the center of the screen is even and it is not noticeable when watching sports like hockey, a sport where the slightest uniformity issues are usually very easy to see.
Looking at the 5%, we can see that both bottom corners are a bit brighter than the center and this is mostly due to the clouding of the panel, as the same brighter zone are also visible on the black uniformity. In any case, this is almost not noticeable when watching normal content, and as such, is not problematic.
Bad viewing angle, but fairly typical for a TV with a VA panel. Colors and blacks degrade significantly when viewed from even a small angle, while brightness degrades less at an angle. This bad viewing angle makes this TV not well suited for a room where people often sit to the side of the TV and view it at an angle; in such cases an IPS TV with a good viewing angle, like the LG SJ8500, may be better.
The Sony X900F black uniformity is very good. Looking at the native black uniformity picture (when the local dimming is turned completely off) our unit has some faint flashlighting, especially near the edge and the corners of the TV. The clouding is not too strong and when looking at normal content, should not be too apparent.
Turning on local dimming hides most issues, but it comes at the cost of blooming around bright objects (like the center cross in this picture).
Note that the screen uniformity varies per unit, and another X900F could be better or worse than the unit we bought.
The reflection handling of the Sony X900F is great. The semi-gloss finish does diffuse reflections slightly, but not as much as more hazy TVs such as the Samsung MU8000. The anti-reflective coating works well to reduce the total reflections and provides very similar performance to last year's X900E. This should be fine for most rooms, but reflections may be distracting in a very bright room or if sunlight falls directly on the TV.
Out of the box, the accuracy of the Sony X900F is excellent, and for most people, this TV could be used right away without the need for any calibration.
The most accurate picture mode out of the box is the 'Custom' picture mode, and it is also one of the picture modes that gives you the most control over all the picture setting available.
The 'Cinema Pro' is also very accurate, but this picture mode targets a gamma closer to 2.4, rather than our desired 2.2 target.
The accuracy is outstanding after calibrating the white balance. Unfortunately, the lack of color management system on Sony's TVs can't be corrected further.
Overall, the calibration here did only bring some small corrections, as the TV was already very accurate out of the box, and the process was very fast and without issues.
You can see our recommended settings here.
Great wide color gamut; saturated colors in HDR content will be shown fairly well, but not quite as well as some other TVs like the LG OLED B7A. The TV's color accuracy for less saturated colors is also fairly good, so the overall HDR image will be accurate.
The TV's HDR EOTF follows the target PQ curve very closely up until it rolls off and clips at its peak brightness. The EOTFs in the 'Game' and 'Graphics' picture modes also follow the target closely. Users who want a brighter HDR image can increase the TV's 'Gamma' and 'Adv. contrast enhancer' settings, which will raise the EOTF to be brighter than the target curve.
Update 05/02/2018: The color gamut was erroneously measured at a 50% stimulus. It has been remeasured at 75% stimulus to be in line with our other TVs. The results remain almost identical.
Decent color volume in HDR. The Sony X900F's local dimming does a good job of extending its wide color gamut down to a range of different brightness, so darker colors will look as saturated as brighter colors.
Excellent gradient performance; no major banding is visible during normal usage when playing 10 bit content (such as HDR). When playing SDR some banding may be visible when the content is 8 bit, but this banding can be reduced by enabling Sony's "Smooth Gradation" feature.
No temporary image retention could be noticed on the Sony X900F white running our test. This is good for those wanting to use this TV as a PC monitor. Note that this is a different result from our 2017 X900E, as the later did show sign of very faint image retention.
We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.
Motion looks great on the Sony X900F; it has a fast pixel response time, a backlight without much visible flicker, an optional flicker mode, 120 fps motion interpolation, and it can remove 24p judder from all common sources. However, there are some aspects of its motion that could be better; its fast pixel response time can make low frame rate content look a little stuttery at times, and its optional flicker mode doesn't flicker at 60 Hz.
Excellent pixel response time, good enough for fast-moving content. Most of the blur in the photo is caused by 60 fps persistence; almost no ghosting trail is visible behind the moving logo, which is excellent. One flaw though is the severe overshoot on the 0-20% transition; this means that some bright ghosting may be visible in dark scenes during fast motion.
The backlight does flicker, unlike some other Sony TVs like the 2017 X800E; and this flicker is always present, even at maximum backlight. However, because the flicker frequency is a very fast 720 Hz it will be almost unnoticeable to most people.
The 2018 Sony X900F can flicker its backlight at 120 Hz, which makes motion look clearer by reducing persistence blur. Unfortunately, it can't flicker at 60 Hz, so 60 Hz content will have visible duplications in its motion, but some may find it preferable to no flicker. On Sony TVs, BFI is activated by setting "Motionflow" to "Custom" and increasing the "Clearness" slider.
Sony has implemented a new BFI mode on "Clearness = 1", which they call "X-Motion Clarity". When in this mode the real scene brightness decreases by about 60 nits compared to with no flicker("Clearness = 0"), but as the brightness of the screen decreases its flicker becomes more severe, similar to how a TV with PWM dimming behaves. When this is combined with local dimming, dimmer zones of the screen will have clearer motion than brighter zones. This is different from the flicker behavior in "Clearness" 2 and Max, where zones of different brightness will have similar flicker and motion clarity. We recommend "Clearness = 1" when users want clearer motion but don't want to sacrifice too much screen brightness. Note that none of these 'Clearness' settings affect the input lag in the 'Game' picture mode.
The TV has a 120 Hz panel, and its processing can interpolate lower frame rate content to 120 fps to match the panel. This optional feature is also called the "soap opera effect". It produces smoother looking motion but can look unnatural to some people, and also adds small artifacts in its processing that can be bothersome to some.
The TV is decent at showing low frame rate content smoothly (like movies and 30fps video games), but the TV's fast pixel response time can make motion look a little stuttery, especially in wide panning scenes, because the frame stays static for 31 ms. 60 fps content looks smoother because the frames are on screen for a shorter amount of time.
The Sony X900F can display, without judder, 24p movies no matter from which sources they are playing. To achieve this though for every source including the native Netflix app, you need to set (from the Motion tab in the picture setting) the 'Motionflow' to 'True cinema' and set 'CineMotion' to 'High'. This isn't needed for direct 24p sources.
The TV doesn't support a variable refresh rate.
The Sony X900F supports all the common input signals, including HDR. It has great low input lag for 4k signals, and good low input lag for 1080p signals, so it will be very responsive when gaming. It also has some useful PC monitor features such as 4:4:4 chroma subsampling support and 1080p @ 120 Hz support. Note: Only HDMI ports 2 & 3 support full bandwidth, but HDMI port 3 is also the audio return channel. If you have a receiver which 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. In this case it may be best to connect your receiver using an optical (Toslink) cable.
Great low input lag, especially when playing 4k video. The 1080p input lag is higher than for 4k, but is still good enough for most gaming. Overall, the input lag is very similar to last year's X930E, which is understandable because both use Sony's 'X1 Extreme' processing engine (unlike the 2017 X900E); however, many TVs from other brands have lower input lag, such as the Samsung MU8000, LG SJ8500, and TCL P607.
Update 08/13/2018: We have retested the input lag with the latest firmware (PKG6.5603.0175NAA) and it remains the same.
All common resolutions are supported. 4k @ 60 Hz @ 4:4:4 or 4:2:2 is only possible on HDMI inputs 2 and 3, and only when 'HDMI Enhanced Format' is enabled. 4:4:4 chroma subsampling is only shown properly in the 'Game' and 'Graphics' picture modes.
Update 06/11/2018: A note for Xbox One X and Xbox One S owners: 120 Hz from the Xbox will not work with this TV (and all 2018/2017 Sony's we've tested), because the TV requires a forced resolution for 120 Hz to be displayed.
Update 06/12/2018: It turns out 1080p @ 120 Hz is possible, when the Xbox's connection type is changed from Auto-detect (Recommended) to HDMI: (Xbox > Settings > Display & sound > Video fidelity & overscan > Display > Connection > HDMI). Unfortunately in this mode 4k, HDR, 50 Hz and 24 Hz aren't possible, so this mode is only recommended when the higher refresh rate of 120 Hz is more important to you than these other features. Find out more here.
Update 06/18/2018: Correction, 24 Hz and 50 Hz are in fact possible with the Xbox's connection type set to HDMI.
There is one composite input (labeled 'Video In') however it is a 3.5mm jack, and so requires an adapter for most devices. An example of the correct adapter can be found here
Update 06/11/2018: Dolby Vision support has been added as of firmware (PKG6.5603.0175NAA); the scores have been updated.
The sound quality of the Sony X900F is below-average. It does have a well-balanced sound, and it can get fairly loud. However, they don't have any sub-bass, and they are prone to pumping and compression artifacts under heavier loads. So adding a sound bar to your setup would be beneficial.
Average frequency response. It has a relatively deep bass, but not deep enough to produce deep rumbles (i.e. explosion sound effects). The frequency response is quite flat and well-balanced, however, the TV was not able to remove the resonances of the test room (high-bass and low-mid) due to a lack of self-calibrating system. Additionally, the TV does get pretty loud, but they could produce some pumping and compression artifacts near their maximum volume.
Sub-par harmonic distortion performance. Similar to other Sony TVs we have measured, this TV has little distortion at low volumes. However, at maximum volume, the X900F produces a lot of distortion, but this kind of distortion won't be very audible with real-life content (movies, music...).
The X900F runs Sony's version of the Android TV interface, which isn't as easy to use as some other smart platforms but has a lot of apps, and access to the amazing Google Assistant. The TV's main interface is unfortunately quite crowded, and often has moments of lag and choppy animations. This is redeemed somewhat by Android TV's vast Google Play Store, which has a dizzying array of apps, some shared from Android phones and tablets. Android TV also has access to the amazing Google Assistant voice control feature, that can directly execute many commands on the TV like "open Netflix" and "how's the weather?".
The Android TV interface isn't as easy to use as some other smart platforms. The home screen is very long, requiring a lot of scrolling in order to see everything. The performance is also quite inconsistent; sometimes the TV will open menus quickly and have smooth animations, but other times menus will lag for a second or two before opening, and their animations will be choppy. The home menu is especially slow to open, which is unfortunate because of how often it needs to be used. This is alleviated somewhat by the many buttons on the Sony remote and the voice control feature.
Update 04/09/2019: Google has pushed an update to some Sony TVs that run the Android Oreo update. This update adds a row of Google Sponsored Content in the second row of the home page. Unlike the existing sponsored content, this row cannot be remove normally from the Customize Channels menu menu. There is a workaround though, which is available here.
The ads look similar to the ones seen on the Sony X950G.
One of Android TV's strengths is access to the Google Play Store, which has more apps than almost all other smart platforms. The apps run fairly smoothly and with minimal lag, unlike the frequent mini-hangs of the main Android interface. The X900F is one of the best internet TVs we've reviewed in 2018.
Update 01/09/2019: YouTube app version 2.04.05 has added HDR support, seperate from the Android Oreo update.
Correction 02/22/2019: The YouTube app does support HDR, but it is currently bugged. The brightness and color gamut do not switch automatically, and there are issues playing files with a resolution higher than 1080p.
The X900F comes with Sony's lower-cost remote with rubber chunk buttons, unlike the better remote that came with last year's X900E. The remote is still very usable, and has more buttons than most remotes, at the cost of being larger than most remotes.
The remote can connect to the TV by Bluetooth so that its microphone can be used with the TV's Google Assistant voice control feature. Google Assistant can perform a lot of actions on the TV, as well as interface with the rest of the Google ecosystem; commands like 'open YouTube', 'switch to HDMI 3', 'pause video', 'how's the weather' and 'turn off the TV' all work well, though commands to change picture settings like 'set the brightness to 20' and 'switch to Game mode' don't work.
Sony's 'Video & TV SideView' smartphone app has more functionality than Google's Android TV app, but it's still not as good as the apps of some other platforms like Roku. Sony's app can act as multiple kinds of remotes, like a touchpad, mouse pointer or a clone of the physical remote buttons. The app can also use the phone's microphone to send voice to the TV's Google Assistant voice control feature, which is handy.
Update 07/11/2018: Sony's Video & TV SideView remote app has been retested on version 5.5.0. The remote app can now stream video files and can only directly launch apps. The data fields have been updated.
Update 10/12/2018: The remote app can directly launch both apps and inputs, even on version 5.5.0; "Apps Only" was a mistake. The value has been corrected to "Both".
We tested the 55" (XBR55X900F). For the most part, we expect our review to be valid for the 49" (XBR49X900F), 65" (XBR65X900F), 75" (XBR75X900F) and 85" (XBR85X900F).
Depending on where you are, the X900F is also known as the XF90, X90F, or X9000F. Although we haven't tested them, we don't expect any significant differences between them other than minor regional differences, including different tuners.
If someone comes across a different type of panel or if their Sony X900F 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 Sony X900F is a solid performer across the board. It can produce deep blacks aided by local dimming for watching movies in a dark room, has excellent motion handling for sports or fast-paced games, and can produce bright, saturated highlights for HDR. Having said that, it faces tough competition in the price bracket - especially from last year's X900E. See our recommendations for the best smart TVs.
The Samsung Q8FN is slightly better than the Sony X900F. The Q8FN has better reflection handling, although the Sony X900F is brighter. The Samsung Q8FN is better for gaming, as it has lower input lag, and it supports FreeSync and automatic low latency mode. The Sony X900F has a better response time, so motion is clearer with less blur, but the Q8FN is excellent as well. While both TVs have an optional black frame insertion feature, the Q8FN can flicker at a lower frequency, which is good for content with a lower frame rate.
The Sony X900F and the Sony X950G both have very similar performance. The X950G has lower input lag, which is good if you play video games or use the TV as a PC monitor. The X950G is brighter than the X900F, but the X900F has marginally higher native contrast ratio, although neither of these differences are noticeable under normal conditions.

The Samsung Q9FN is a bit better than the Sony X900F. The Q9FN has better dark room performance thanks to the better local dimming feature and better black uniformity. The Q9FN has better reflection handling and can flicker at 60Hz which is good for clearing up motion. The Samsung Q9FN has a few features geared towards gamers, including auto low latency mode and support for AMD's FreeSync 2. The Sony X900F has a faster pixel response time, so motion looks smoother and has less motion blur.
The LG B8 OLED is a better TV than the Sony X900F. The OLED is better for watching movies in a dark room due to the perfect blacks. The C8 is also better for those with wide seating as the image remains accurate when viewed at an angle. On the other hand, the Sony is a much brighter TV that does not have the burn-in risk and can be placed in bright environments.
The Sony X900F and the Sony X930E have very similar performance. The Sony X900F has a marginally better response time that you might notice if you are a hardcore video gamer. On the other hand, the Sony X930E has better contrast that produces deeper blacks in dark environments and is great if you watch HDR content. Also, the Sony X930E has somewhat better SDR peak brightness that you will appreciate if you watch TV shows in a brighter room.
The LG SK9000 is a better choice if you are going to watch TV from the side, as it has better viewing angles. The Sony X900F is better for directly in front seating arrangements. The LG SK9000 has better input lag and better black frame insertion (BFI), which make it slightly better for gaming and can be attractive to gamers. The Sony X900F has better contrast and local dimming, and much better black uniformity so it can display deeper blacks that improve picture quality in a dark room and make it a much better TV for movies. The Sony also has a faster response time and better gray uniformity that make it a marginally better choice for sports fans.
The LG C8 is significantly better than the Sony X900F. The LG C8, like all OLED TVs, is suitable for a large room with a wide seating arrangement. It also has perfect blacks, making it ideal for dark room viewing conditions. The LG C8 has an instantaneous response time which leaves a very small blur trail in fast-moving content like sports, and a lower input lag which is great for gamers. The Sony X900F, on the other hand, has a VA panel that does not have the permanent burn-in risk of the OLEDs and can get brighter.
The Vizio P Series Quantum is a better TV than the Sony X900F overall. It has slightly better reflection handling and is much brighter, which is great if you watch TV shows or sports in brighter rooms. The Vizio P Series Quantum also has better local dimming that makes blacks look deep in a dark room. The input lag of the Vizio P Series Quantum is better, and this is great for gamers. On the other hand, the Sony X900F has better color accuracy out of the box, smoother gradients, and more intuitive smart features.
These are two different types of TVs. If you have a room with a wide seating arrangement, then Sony X800E might be the better choice as the image remains accurate when viewed from the side. In all other situations, however, the X900F seems to be the better choice. The X900F has much better dark room performance, can get much brighter both in SDR and in HDR, has a faster response time, and the image is crisp with minimal motion blur trail behind fast-moving objects. The X900F can also remove 24p judder from any source.
The Sony Z9F is slightly better than the Sony X900F. The Sony Z9F has wider viewing angles as it incorporates Sony's 'X-Wide-Angle' technology at the expense of lower contrast ratio. The Sony Z9F can compensate slightly for the lower contrast ratio through the better implementation of local dimming support. In most other aspects, the two TVs are very similar.
The Sony X900F is better than the 2017 Samsung Q7F. The X900F has a much more effective full array local dimming backlight, which improves dark room performance. The X900F is a lot brighter in SDR and HDR, and small highlights stand out a lot more in HDR. The Sony also has Dolby Vision support which can further improve the quality of some HDR content.
The Sony X900F and the Sony Z9D have very similar performance. The Sony X900F has a faster response time, which is great when playing video games, and marginally better judder removal if you watch a lot of low fps content. On the other hand, the Sony Z9D has a slightly better local dimming and marginally better black uniformity and can display deeper blacks. This will be appreciated by those who enjoy watching movies and HDR content in dark rooms.
The Sony A8F is better than the Sony X900F, unless the possibility of burn-in inherit in OLED technology concerns you. The A8F delivers a perfect dark room experience, as the self-emissive technology can turn off or dim individual pixels. The A8F has much wider viewing angles and better reflection handling. The X900F uses a VA panel, which is not expected to experience burn-in.
The Sony X900F is marginally better than the Sony X940E. The X900F has a much faster pixel response time, so motion looks much smoother with very little motion blur. The Sony X940E has a poor response time, but it has a better black frame insertion feature that improves motion blur. The X940E has better dark room performance, with a better local dimming feature and better black uniformity.
The Sony X900F is better than the 2017 Samsung Q9F. The X900F has a much better local dimming feature and better black uniformity, great for dark room viewing. The Samsung Q9F has a more advanced black frame insertion feature which can clear up motion at the expense of some brightness, and has lower input lag for gamers or for use as a monitor.
The Sony X900F is slightly better than the Vizio P Series 2018. The X900F performs better in a bright room thanks to the better anti-reflective coating, and it is brighter and better able to overcome glare. The X900F also has wider viewing angles and has a more robust smart platform. The Vizio P Series 2018 has lower input lag for gaming or for use as a monitor. The P Series also has a more advanced black frame insertion feature and a better local dimming feature.
The LG SK8000 has an IPS panel with better viewing angles and thus is more suitable for a large room. The Sony X900F is a better choice if you are sitting directly in front. The LG SK8000 has slightly better input lag and a better black frame insertion (BFI) feature to clear up blur that gamers will appreciate. On the other hand, the Sony X900F has better local dimming and better black uniformity and contrast that allow it to display deeper blacks, making it something you will appreciate in a dark room while watching movies. The Sony can also get brighter and has better HDR performance.
The Sony X900F is better than the LG SK9500. The Sony X900F is better for watching movies or HDR content right in front, as it has better native contrast ratio, better local dimming along, and better black uniformity. The Sony X900F also has a faster response time, which is great for watching sports. The LG SK9500 has an IPS panel that gives better viewing angles, and this is good for wide seating arrangements and a lower input lag that makes it very responsive for playing video games.
The Sony X900F is much better than the Sony X830F. The Sony X900F supports local dimming and has a better native contrast ratio which produces deep blacks and thus a better SDR and HDR movie watching experience in a dark room. The Sony X900F also has better peak brightness and better reflection handling which make it more suitable for a bright room. It is also better for gaming as it has marginally better input lag.
The Sony X900F is much better than the curved Samsung NU8500. The Sony X900F has better local dimming and better native contrast ratio. Along with the better black uniformity and better brightness, it can deliver better dark room movie and HDR movie watching experiences. Also, the Sony X900F has better reflection handling and faster response time, so it is a better choice if you watch a lot of sports or TV shows in a room with many light sources.
