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.

Our Verdict

8.2 Mixed Usage

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.

Pros
  • Very deep and uniform blacks
  • Very bright
  • Exceptional local dimming
Cons
  • Image degrades when viewed at an angle
  • Fast moving objects often have visible trails
9.0 Movies

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.

8.5 TV Shows

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.

7.6 Sports

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.

7.8 Video Games

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.

8.9 HDR Movies

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.

8.1 HDR Gaming

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.

7.9 PC Monitor

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.

Design
Style
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. 

Design
Stand

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 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 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.

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 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 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.

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.

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.

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.

Update 06/12/2018: A note for Xbox One X and Xbox One S owners: 1080p @ 120 Hz from the Xbox is only supported on this TV 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.
