The X940E is a great large 4k HDR smart TV. It produces some of the best blacks found on LED TVs, and it can get quite bright. The excellent local dimming and ability to display a wide range of colors results in a great HDR experience. The X940E has some motion blur though, which makes it less of a good choice for sports or video games but doesn't impact the excellent movie performance.
- Very deep and uniform blacks
- Very bright
- Exceptional local dimming
- Image degrades when viewed at an angle
- Fast moving objects often have visible trails

Updated with newest firmware (PKG6.2648.0065NAA). The input lag and 24p playback have been retested and are unchanged.
The design of the X940E is familiar to any Sony fans due to the minimalist and industrial look. It has a small, central stand which supports the TV well and can still fit on most table tops. The TV provides excellent cable management with guidance out the back of the stand, and has excellent build quality.
The X940E has a central stand, similar to most Sony TVs such as the X930E. Despite the small footprint, it still supports the large TV well.
Footprint of the 75" TV stand: 20.1" x 12.8"
The back looks similar to the X930E. It has many panels which reveal a great cable management system. Due to the design of the plastic back the panels aren't noticeable when attached.
The borders have an average thickness, but look and feel good with a metal edge.
2.56" (6.5 cm)
The TV is quite thick when viewed from the side. Due to the size of the TV, this isn't really noticeable if wall-mounted though.
The X940E never gets more than a little warm, and the heat is well distributed across its surface.
The build quality of the X940E is excellent. The rear of the TV is all plastic but feels high-end and all of the parts fit together very well.
The Sony XBR75X940E LED TV has an impressive picture quality. Dark scenes look amazing due to the high contrast ratio and the excellent black uniformity, especially when the TV is in a dark room. When set in a bright room, the picture quality remains good, since the TV can get very bright to fight any glare from a bright lamp or window and it can also deal very well with reflections. The overall gray uniformity is average, but luckily not too much dirty screen effect is visible. The viewing angle is disappointing though, so the X940E is better suited for people who have a living room with a narrow seating arrangement, as the picture quality is best only when sitting in front of the TV. The X940E has excellent local dimming and a high HDR peak brightness, so highlights really stand out when compared to normal SDR content. The Sony X940E is really a top performer when it comes to HDR.
4941 : 1
Contrast with local dimming
11634 : 1
The Sony X940E has a great native contrast ratio. Hovering near 5000:1, the X940E can display dark scenes very well with deep blacks. This high contrast ratio is especially good when the TV is set in a dark environment.
When the Local dimming is activated, the contrast ratio goes up to an outstanding 11634:1, which is one of the highest contrast ratios we have measured for an LED TV.
The local dimming feature on the X940E works extremely well and looks about as good as the Sony Z9D when compared side-by-side. The X940E can display our moving highlight very bright while keeping the rest of the screen really dark and with limited blooming. The time reaction is also very fast and the turning on and off of the dimming zones is not really noticeable.

Outstanding SDR peak brightness. The TV's local dimming helps to make highlights in dark scenes incredibly bright, but even the TV's worst case brightness, the 100% white window where local dimming can't be used, is still pretty bright. The TV's brightness does decrease a little as it warms up; our measurements were done after the TV had warmed up. Overall the TV is a bit less bright than its cousins, the X930E and Z9D. A plot of brightness over time is shown here.

Outstanding HDR peak brightness. The TV's brightness in the real scene test is close to its best case brightness, indicating that the TV's local dimming is effective even in more realistic scenes. However the TV isn't as bright during extremely bright scenes like our 50% and 100% white window tests, because local dimming isn't as effective here, but even in these worst case scenes the TV is still pretty bright. The TV did decrease its brightness a little as it warmed up; our measurements were taken after the TV was warmed up. Overall the TV is a bit less bright than the X930E and Z9D. A plot of brightness over time is shown here.
The gray uniformity of the X940E is ordinary and it is situated in the same ballpark as the X930E and the 2016 Z9D. It suffers from the same problems with darker edges and corners. The middle of the screen is fairly free of imperfections, which is a good since dirty screen effect is kept to a minimum.
Looking at our test picture of the 5% gray, the X940E is a bit worse looking than on the X930E. The bottom edge of the screen is a lot brighter than the rest of the screen and we confirmed this by measuring the luminosity of the screen in that region and it was clearly brighter than the middle or top of the screen. There are also large horizontal bands that seem darker than the rest of the screen. Both of those issues could be noticed during dark scenes and especially when the TV is set in a dim lit room.
Surprisingly, the local dimming strongly influences the gray uniformity. When the local dimming is set to 'High', the uniformity looks much more better as you can see here, but if set to 'Low' then the large bands that are visible on our 5% gray picture (local dimming set to 'Off') are much more visible, as you can see here. We recommend not to use the 'Low' setting of the local dimming as it can introduce some banding in dark scenes.
Native Std. Dev.
Std. Dev. w/ L.D.
The X940E has an excellent native black uniformity with some minimal clouding in the upper right side of the screen, but this is not really visible while looking at normal TV content.
With local dimming turned on, the black uniformity becomes almost perfect and no issues can be seen. This is a very good example of how effective the local dimming is on this TV.
The Sony X940E can display our gradient test image without any problems, as you can see on our test picture. From the light to the dark shades, everything is smooth, even the grayscale. Note that this test what was done with the 'Smooth gradation' feature turned off.
After calibration, which was pretty easy and fast to do, the X940E performed extremely well. The white balance was easily corrected via the 2 point and 10 point calibration setting and as a result, the gamma was flattened to track almost perfectly to our 2.2 target. As with other Sony TVs, there is no color management system to further correct the color accuracy even though the color dE was brought down via the corrections applied to the white balance. In the end, the Sony X940E is really accurate.
You can see our recommended settings here.
Low quality content such as DVDs are upscaled well. Details are preserved and the image isn't too soft, although some halo artifacts are noticeable along edges.
720p content such as cable is upscaled well. There is no loss of details.
1080p content such as Blu-rays look great and the image remains clear.
No issues can be seen with native 4k content.
Wide color gamut, though not as wide as on some other high end TVs like the Samsung Q7F, KS8000 or Sony's A1E. The TV is fairly accurate for most of its color range, but like many other TVs it struggles with reproducing deep greens in HDR content, which also ends up hurting its cyan performance.
The TV's EOTF almost flawlessly follows the HDR PQ curve up to where it clips at its peak brightness. This EOTF was measured in the Custom picture mode, the EOTFs for the Cinema Pro and Game modes are shown here and here.

The Sony X940E does present some image retention right after the 10-minute burn-in scene of our test clip, but the retention looks very dim and it fades really fast. After 2 minutes of recovery, nothing could be picked up by our analysis process, which is a good result. Even though it has some very minor image retention, this isn't a problem.
The X940E is great at handling reflections. Unlike the X930E, it has a glossy finish which works well to reduce the intensity of direct reflections. Unlike the glossy A1E, it doesn't have much of a purple tint so reflections appear natural. This is a good result even for a bright room.
The X940E doesn't support 3D, like most TVs in 2016.
The X940E has a mediocre handling of motion. It has a long response time, so motion blur may be seen depending on the content. For movies this isn't an issue, but for PC use or some games a long trail can be seen. The TV uses PWM to dim the backlight, but the frequency is high enough to not be noticeable. It is possible to reduce the frequency to clear up motion significantly. Some minor judder is present when watching movies from a PC or cable, but most people won't notice this. Fans of motion interpolation can introduce a strong soap opera effect on the 120Hz panel.
80% Response Time
100% Response Time
The response time of the 75" X940E is bad, resulting in a long (but faint) trail following moving objects. This isn't noticeable in all content, and isn't an issue for watching movies but does cause visible blur behind 60 fps games or sports.
PWM Dimming Frequency
The Sony X940E uses PWM at 720Hz to dim the backlight, starting at 13/50 backlight setting, but at that frequency it is not noticeable. Lowering the setting reduces the amplitude, while duty cycle remains constant. It is possible to decrease the flicker frequency to 60Hz and clear up motion, for those who don't mind visible flicker. To do so, set 'MotionFlow' to 'Custom' and increase the 'Clearness' slider.
Judder-free 24p via 60p
Judder-free 24p via 60i
The Sony XBR75X940E can only display 24p movies playing via 24p sources like DVDs and Blu-rays player smoothly. 24p movie playing via 60p/60i sources like cable or satellite boxes do present occasional judder even with 'Motionflow' set to 'True Cinema' and 'Cinemotion' set to 'High'.
Similarly to what we have seen for other 2017 Sony TVs, this is likely a firmware problem that could be fixed. We will update the review if we find that this issue is fixed in a future firmware update.
Update 07/18/2017: The TV has been tested with the newest firmware update (PKG6.2648.0065NAA). The 24p playback remains the same.
Motion Interpolation (30 fps)
Motion Interpolation (60 fps)
The X940E can interpolate lower frame rate content up to the panel's native refresh rate of 120Hz. To do so, set 'MotionFlow' to 'Custom' and increase the 'Smoothness' slider. For 30fps content it is also necessary to set 'CineMotion' to 'Medium' or 'High'.
The Sony X940E supports all the common input signals, including HDR, and should be able to properly display any content. It has good 4k input lag, but its 1080p input lag may disappoint competitive gamers.
4k @ 60Hz + HDR

4k With Interpolation
1080p With Interpolation
Low input lag for a 4k input, which should please all but the most competitive gamers; but higher input lag for a 1080p input. This should be good enough for most people but may disappoint competitive gamers. Both the Game and Graphics picture modes have low input lag, and can show 4:4:4 color properly. Overall the input lag is very similar to the X930E and Z9D, which also use the Sony x1 Extreme processing engine.
Update 07/18/2017: The TV has been tested with the newest firmware update (PKG6.2648.0065NAA). The input lag remains the same.
Update 09/20/2017: Tested 1080p @ 120 Hz input lag using our new input lag tool. It is much faster than the 1080p @ 60 Hz input lag, likely due to the TV bypassing some processing when it detects such an unusual signal.
1080p @ 60Hz @ 4:4:4
All the common input resolutions are supported. 4k @ 60 Hz @ 4:2:2 or 4:4:4 color is only supported on HDMI inputs 2 and 3, and only when 'HDMI Enhanced Format' is enabled. 4:4:4 color is only properly displayed in the Game or Graphics picture modes.
When using the TV as a PC monitor, 1080p is listed as the default resolution. 1080p @ 120 Hz is properly supported but must be added as a custom resolution, because it isn't listed by default.

Below average distortion performance. The X940E has reasonable THD at a lower volume, but it steeply rises as levels are raised.
The Sony X940E ships with Android TV 6.0 Marshmallow, but received an update to Android TV 7.0 Nougat prior to testing. Nougat brings a few new features to Android TV, such as a picture in picture mode and multitasking menu, but it fails to address the main problems with the Android TV platform, namely ease of navigation, lag and frame drops, and a lack of smart features in the remote.
Other smart features of Android TV remain unchanged. The Google Play Store still has a larger selection of apps than many other smart platforms. Content can be cast to the TV from a smartphone or tablet using the TV's "Chromecast built-in" functionality, or played from a USB drive connected to one of the TV's three USB ports. The remote has a built in microphone for voice search, which works well.

The TV has no ads in its main interface, but third party apps can have ads. There is an option in the TV's settings to opt-out of personalized advertising for these ads.
The first row of the home page is filled with suggested content. In the 'Home' section of the TV's settings you can opt out of all sources of suggested content until all that's shown is a line saying 'No recommendations available at this time'. After the TV has been restarted more sources may appear but can also be disabled.

Other Smart Features
The remote is rather large with a lot of buttons. Fortunately most of the commonly used buttons are clustered within easy reach around the navigation pad in the center, except the power and input buttons at the top which are hard to reach. The remote has a built in remote for Android's voice search, which only searches for content and lacks the advanced voice command features found on other smart platforms such as Samsung's Tizen. The remote is identical to those of the X930E and X900E (same model number).

). Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.
The X940E is a great LED TV, but it faces steep competition in its price range from OLED TVs. It does have the advantage of being larger than average though.
49" 55" 65" 75"
The Sony X900E is a slight step down in Sony's range of LED TVs compared to the X940E. It offers very similar performance, but it has worse local dimming and doesn't get quite as bright. If you mind the slight reduction in brightness for HDR, the X900E is the TV to get since it is significantly cheaper.
The C7 is LG's current entry-level OLED model. It isn't found in the same 75" size as the X940E, but it has better picture quality, motion and input lag than the X940E. It isn't as bright, but if you don't mind the size difference it is a better TV.
100" 65" 75"
The Z9D is the top of the line TV from Sony. It's a very similar TV to the X940E. The Z9D does get a bit brighter, but most people won't really notice the differences between the two, making the X940E seem like a bargain in comparison.
55" 65" 75"
The Samsung Q7F is the entry-level model in their QLED line of LCD TVs. It can produce a substantially wider range of colors, and it has better motion and input lag. Its overall picture quality is worse though since its local dimming is not nearly as good as the X940E and it cannot get as bright for HDR. Since they're both found around the same price, most people will be better suited with the X940E.
Vizio P Series 2016
50" 55" 65" 75"
The Vizio P Series 2016 is a 4k LED TV that features a similar local dimming feature to the X940E. It isn't quite as sophisticated as the one found on the Sony, but it is still quite good. Overall, the Vizio P doesn't get as bright, making a bit less effective for HDR, but it does offer some significantly better native motion and input lag for gaming. It is significantly cheaper though, so if the X940E is out of your budget, the Vizio is a great alternative.
Great TV for mixed usage, the X940E has excellent picture quality in most environments. It has some motion blur that might bother people more sensitive to it though.
Excellent TV for watching movies. The X940E has some of the best local dimming available, bringing it close to OLED for most scenes. It's also able to turn off black bars found in movies completely which is great.
Very good TV for TV shows. The X940E's upscaling of lower resolution content is as good as it gets, and it gets more than bright enough to be enjoyed in most environments.
Good TV for watching sports, the screen is uniform and bright, leading to no major issues with clarity, but the X940E does have some issues with motion which can cause fast moving objects to have long trails following them.
Good TV for playing video games. Input lag is low in 4k, which is great for keeping the TV responsive. The size and picture quality helps keep the experience very immersive. Some motion blur is present though, which can cause issues with clarity, but it can somewhat be circumvented by using a flickering feature.
The X940E does exceptionally well with HDR movies. It's one of the brightest TVs currently available, and the great local dimming and handling of gradients produce great dynamic range. It doesn't have the widest color gamut available, but it's wide enough to give a strong visual impact.
Very good TV for HDR gaming. Little lag is present with a 4k HDR input which is essential, and the overall HDR performance is some of the best we've seen.
Good TV for use as a PC monitor. Supports all the relevant resolutions, even 120hz for better PC gaming. The input lag is also low, which makes navigating the desktop great. Unfortunately though, it does have a fairly narrow viewing angle, and long trails can be seen following moving elements such as scrolling text or the mouse cursor.
