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.

This TV is currently our best 70-75 inch TV.

Sony X940E Design Picture
Curved : No

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. 

Stand
Sony X940E Stand Picture

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"

Back
Sony X940E Back Picture
Wall Mount : Vesa 400x300

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.

Borders

Borders : 0.55" (1.4 cm)

The borders have an average thickness, but look and feel good with a metal edge.

Picture Quality

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.

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.

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.

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.

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 XBR75X940E is pretty accurate out of the box. There is a bit too much red and blue toward the higher end in the white balance, but even then we are still hovering close to a dE of 3, which it still very acceptable for home use. The gamma is almost spot on and the Color dE is very acceptable. This is in line with other Sony TVs tested before, as they tend to be very accurate out of the box.

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.

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.

Motion

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.

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.

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.

Update 11/10/2017: Retested input lag with the latest firmware (PKG6.2669.0070NAA); there was no significant change.

Sony X940E Smart TV Picture
Smart OS : Android TV
Version : 7.0

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 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).

Update 12/11/2017: Google Assistant has now been added to Android TV on Sony TVs, and it brings a lot of new features to the voice control: commands like 'open Netflix', 'switch to HDMI 1', 'pause video', 'how's the weather' and 'turn off TV' all work well, though commands to change picture settings like 'set the brightness to 20' and 'switch to Game mode' don't work. The remote score has been increased to reflect the new fuctionality.

Compared to other TVs

Top left: Sony A1E (XBR55A1E). Bottom left: LG C7 (OLED55C7P). Middle: Sony X940E (XBR75X940E). Top right: Sony Z9D (XBR65Z9D). Bottom right: Samsung Q7F (QN55Q7F).  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.

Sony X900E
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.

LG C7
55" 65"

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.

Sony Z9D
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.

Samsung Q7F
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.

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.
8.8HDR Movies

What it is HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
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.
8.2HDR Gaming

What it is PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
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.

Questions & Answers

2 ANSWERED QUESTIONS

Why are the X930E, X940E, and Z9D complete trash for 1080p compared to the X900E (X900E is 30 ms vs 40 ms on all Sony's other models)? Can we expect a firmware update to bring that down, or will they end up ruining the X900E by adding another 10 ms in an update to that? It's like they make no effort to improve their TVs for gaming even though they sell game consoles. It's insulting.
The X930E, X940E, Z9D and A1E all use the x1 Extreme processing engine, and all have very similar input lag (the A1E has ~5 ms higher input lag across the board). The X940E, Z9D and A1E were retested after the Android Nougat update and the input lag was unchanged. It's unlikely the X930E, X940E and Z9D's input lag will be reduced by a software update. The X900E and X850E both use the x1 processing engine and have very different input lag than the TVs with the x1 Extreme: better 1080p but worse 4k input lag.

How much did adjusting the color space affect calibration further as compared to other settings alone?
The 'Color Space' option should be kept at 'Auto', or it may oversaturate the colors in Rec. 709 content to turn them into Rec. 2020 colors. It was left at 'Auto' during our calibration, because we calibrate for Rec. 709 content.
