The Sony Z9D is a great full-array 4k LED TV. Picture quality in a dark room is among the best you can find, mostly thanks to its excellent local dimming capabilities. It gets impressively bright, making it a top choice for HDR. Unfortunately, it suffers from issues with motion, and picture quality deteriorates when viewed at an angle.
The Sony Z9D is a great TV for a mixed usage. Picture quality is great overall, it gets bright and deals with reflections well and input lag is good for gaming. It does have issues with motion, making it imperfect for sports watching.
Outstanding choice for movies in a dark room. Mostly thanks to its local dimming unmatched by other LED TVs. The Z9D can produce very deep blacks and can darken black bars flawlessly. Blooming can still be seen though, and it cannot match OLED for displaying starry skies or other scenes with small light sources.
Great TV for watching TV shows. It looks good at every time of the day, and lower resolution content looks sharp. Android TV also has all the popular apps such as Netflix, Hulu, and Amazon video.
The Sony Z9D does a good job with sports. The screen is decently uniform with minimal blotchiness. Unfortunately, the TV's slow response time causes long trails to follow fast moving objects such as players on fields.
Very good TV for video games. Input lag is low, especially in with 4k games. However, the Z9D produces a lot of motion blur. This can cause fast motion games to look a bit blurry, but it can thankfully be circumvented by using the TV's flickering feature.
Remarkable HDR performance. The Z9D is an exceptionally bright TV that produces a very satisfactory HDR experience. It also has a wide color gamut, which allows the TV to produce vivid colors.
Great HDR gaming TV. HDR picture quality is excellent, and input lag remains low. Unfortunately, the TV's motion can be a bit of an issue.
Good PC monitor. The Z9D is capable of displaying every resolution we test, including 1080p @ 120hz. However it has a narrow viewing angle, so corners and sides of the screen darken if sitting too close, and the long response time for 0-100% transitions results in a trail following a mouse pointer on a white background.
The design of the Z9D is great. The small stand supports the TV well and fits on most tables, and the look is quite simple from the front. When viewed from the side the TV is a bit thick, but this isn't an issue for most people. Unfortunately the arrangement of inputs makes some of them quite difficult to access if placed close to a wall.
The stand of the Z9D has a small footprint but supports the TV quite well. It looks quite similar to the X930D.
Footprint of the 65" TV stand: 10.2" x 17.2"
The rear of the TV has removable covers which are held on with magnets and clips. They hide the cables from all HDMI ports and route them through the base of the TV. The covers blend in well due to the texture of the rear. If wall mounted, many of the ports may be difficult to access as they face towards the center of the TV.
The borders of the TV have an average thickness. They look great, with a gold tint around the edges.
The TV is quite thick when viewed from the side. It may stick out a bit when wall mounted, but looks quite good.
The Z9D is surprisingly cool given its high peak brightness. Its local dimming works well to make different areas of the screen only as bright as they need to be, thus saving power and reducing temperature.
The build quality of the Z9D is excellent. The TV feels very solid and well constructed, with better build quality than any other 2016 models we have tested.
The native contrast ratio is great on the Z9D. At around 4300:1, this is enough to make dark scenes with deep blacks look very good. This is also important for people who watch TVs in a dark room, as a lower contrast ratio would make blacks look grayer than what they really are.
It is when local dimming is turned on that you really see where the Z9D outperforms other LED TVs, as the contrast ratio is almost doubled on our checkerboard pattern to reach an amazing 7976:1 ratio. This shows how remarkable the local dimming is on the Sony Z9D.
The Sony Z9D has an excellent local dimming feature. In fact it is one of the best that we have tested yet, as it easily outperformed the Vizio P Series 2016 in a side by side comparison, which was the LED TV with the highest local dimming score in 2016.
The large number of dimming zones really sets the Z9D apart from other local dimming TVs, as blooming is very limited, even when a very bright highlight is displayed on the screen. The reaction time is also very fast, as the zone transitions are smooth when following the moving highlight in our test video.
Outstanding SDR peak brightness. All content will be shown very brightly, even in very bright rooms. When showing dark content like our 10% white window the TV's local dimming makes highlights amazingly bright. Unfortunately in bright scenes like our real scene test clip the local dimming isn't able to make highlights as bright, but even the full-screen brightness is brighter than the peak brightness of most TVs. Overall the luminosity is similar to the X930E, but much brighter than any other 2016 TV we've tested.
A plot of peak brightness over time is shown here.
Outstanding HDR peak brightness. As seen in our real scene test, the TV's local dimming is able to make highlights in HDR content incredibly bright. When showing very bright content such as our 100% white window the TV can't get anywhere near as bright, however very few scenes in HDR content will have the whole scene being that bright at the same time. Overall the brightness is similar to the X930E, but much brighter than any other 2016 TV we've tested.
A plot of peak brightness over time is shown here.
The gray uniformity of the XBR65Z9D could be better. The standard deviation is high and is mostly caused by the darker sides and corners of the screen. There is also a warmer zone just below the center that spans horizontally across almost the whole TV which may affect the standard deviation.
On the bright side, not too much dirty screen effect is noticeable, as we measured only 0.203% which is just a bit over what we consider to be a good value. If you look at our test picture, you can clearly see that the center of the screen is pretty even, which is the region that you would most notice the dirty screen effect.
Looking at the 5% gray test picture, there is a noticeable darker vertical band running from top to bottom but overall, nothing too bad can be noticed and the Std. Dev. and DSE numbers are within a reasonable range, which is good.
Poor viewing angle, but a little better than most VA TVs. Colors wash out when the TV is viewed from even a small angle. People sitting to the side of the TV and viewing it on an angle will not enjoy as good picture quality as people sitting in front.
The black uniformity is excellent on the Sony Z9D. The native black uniformity (without local dimming) is great and is a good sign of the quality of this set. When compared to the X930E, both look very similar but the Z9D has the edge over the newer set with slightly more uniform blacks.
The big difference happens when you turn on the local dimming on the Z9D. Comparing the native black uniformity test picture with the one with local dimming, the difference is outstanding. The excellent local dimming feature of the Z9D removes almost all blooming.
With the factory settings, the Sony Z9D color is a bit warm, but overall it is very accurate. With both the white balance and color dEs being less than 3, this Tv could be used as is by any TV enthusiasts without color accuracy issues.
The calibration process was done without any problems and can be completed quickly as the TV was already quite accurate out of the box. The error in the white balance was brought down to almost nothing (0.25 is negligible) and as a consequence, the gamma curve flattened to track our target curve of 2.2.
As with other Sony TVs, the Z9D does not have a color space management feature. Despite this, the color dE was brought down a bit due to the white balance corrections
You can see our recommended settings here.
Upscaling of low quality content such as DVDs is good. Details are preserved.
720p content such as cable looks good. The image is clear and jagged edges are smoothed.
1080p content such as Blu-rays or high quality streaming looks great. Details can be seen clearly and the image isn't too soft.
The TV's wide color gamut and great tone mapping help it accurately reproduce most colors in HDR content. The big exception is deep greens, which it can't make deep enough even for DCI P3 content. The Samsung Q7F and LG C7 can show deeper greens than the Z9D and have wider color gamuts as a result.
Update 05/22/2018: The TV's HDR EOTF has now been tested. In the Cinema Pro picture mode the EOTF follows the target PQ curve very closely up until it rolls off at the TV's peak brightness. The EOTFs in the Game and Graphics picture modes are nearly identical to that of Cinema Pro.
Decent color volume. The Z9D does a great job showing its wide color gamut at a range of brightness levels, its color volume is only really limited by its color gamut.
The Sony Z9D can display our gradient test image without any perceivable tint problems and also without any banding seen on 8-bit panels. Color banding should not be a problem on this TV, which is excellent, especially for HDR movies.
The XBR65Z9D is free of image retention. Looking at our test picture, no faint remnants of the burn-in scene can be seen. This is an excellent news for gamers who are thinking about getting this TV.
We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.
The response time of the Z9D could be better, resulting in faint trails following moving objects. This is most visible for moving black content on a white background, or vice versa, due to the long 0-100% transition. It can be seen in the moving logo image above, as the trail continues past the left side of the image.
Update 05/05/2017: It is likely that the long response time of the 65" model is different for the 75" model, and may not be an issue for most people.
The Sony Z9D uses PWM at 720Hz to dim the backlight, starting at 25/50 backlight setting, but at that frequency it is not noticeable. Lowering the setting reduces the duty cycle, while amplitude remains constant, until the backlight is at very low intensity.
It is possible to reduce the Z9D's flicker frequency to 60Hz by using the 'MotionFlow' setting and increasing the 'Clearness' slider. This helps to clear up motion blur, but produces visible flicker.
The Z9D has a 120Hz panel which is able to interpolate lower frame rate content. To add motion interpolation (also called the soap opera effect) set 'MotionFlow' to 'Custom' and increase the 'Smoothness' slider. Increase 'CineMotion' to 'High' to reduce the threshold for interpolation, resulting in the strongest effect. Note that this will introduce some artifacts.
The Z9D can display content very smoothly, which is excellent. This is a result of the long pixel response time, which helps to smooth the transition between frames without creating a jarring image. Even for low frame rate content such as movies the image is smooth.
The Z9D can display 24p movies playing from 24p sources like DVDs and Blu-rays without any judder.
When it comes to 24p movies playing via 60p/60i sources like cable or satellite boxes, the Z9D was not able to remove judder from the source completely, even with 'Motionflow' set to 'True Cinema' and 'CineMotion' set to 'High'. When doing this test, the Z9D was able to remove judder approximately 80% of the time, but on some occasions judder was noticed.
We also noticed some signs of interpolation artifacts when 'Motionflow' is set to 'RealCinema' and 'Cinemotion' is set to 'High', similar to what we noticed when testing the X930E. Since most Sony TVs don't suffer from judder playing 24p content over 60p/60i sources, we think there may be a bug that also affects the Z9D. As with the X930E, we will update this review if it gets 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.
The Sony Z9D has a 120Hz panel, but doesn't support any variable refresh rate features.
Low input lag in Game and Graphics modes. The 4k input lag is very good, and should please all but the most competitive gamers. The 1080p input lag isn't as good, but it is still low enough for most people. All these input lag numbers are very similar to the X930E, which also uses the Sony x1 extreme processing engine.
Update 05/23/2017: The TV has been retested after the update to Android TV 7.0 Nougat, and the input lag is unchanged.
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.
All the common input resolutions are supported. 4:4:4 color is only shown properly in the Game and Graphics picture modes. 4k @ 60Hz @ 4:4:4 or 4:2:2 color is only supported on HDMI inputs 2 and 3, and only when 'HDMI Enhanced Format' is enabled.
When using the Z9D as a PC monitor the default resolution is 1080p @ 60Hz. 1080p @ 120Hz is shown properly without any artifacts or jagged upscaling, but it is not listed as an available resolution so you have to add it manually as a custom resolution.
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.
Update 06/18/2018: Correction, 24 Hz and 50 Hz are in fact possible with the Xbox's connection type set to HDMI.
The TV has a shared composite/component port and an additional small composite port that needs an adapter, which unfortunately is not included. An example of a compatible adapter is found here.
Sony has announced that the Z9D will receive Dolby Vision support in a future software update.
Update 01/23/2018: The update enabling Dolby Vision compatibility is now available.
