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.
- Exceptional local dimming
- Gets very bright
- Deep and uniform blacks
- Lots of motion blur, fast moving objects will often have faint trails following them
- Picture quality deteriorates at an angle
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 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 Sony Z9D has an impressive picture quality for an LCD TV. With its great contrast ratio and its excellent black uniformity, the Z9D provides a superb movie watching experience, especially in a dark room. Blacks are very deep and dark scenes are shown well. If set in a bright room, the Z9D does a great job at dealing with reflections and since it can get very bright, it can easily overcome any glare from bright lights or windows. The gray uniformity could be better but since there isn't too much dirty screen effect, watching sports on the Z9D is still decent. HDR movies on the Z9D looks impressive. The high peak brightness paired with amazing local dimming features and accurate color reproduction really make any HDR content shine. The biggest downside of the Z9D is that the picture quality degrades fast when moving off center due to the narrow viewing angle.
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.

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 good 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.
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.
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

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 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.
3D movies look good on the Sony Z9D. There is a noticeable flickering due to the active technology used on this TV. We did a side by side comparison with another TV (LG C6) with the same movie playing on both and we were able to notice some occasional crosstalk on the Z9, but we had to really look for it to be able to notice it.
The motion handling of the 65" Z9D is sub-par. It has a few slow transitions which limit the motion performance, producing some blur which may be an issue for fast-paced content. The TV flickers the backlight, but at a high frequency so it isn't noticeable. It is possible to produce more visible flicker which helps to clear up some of the motion blur. Movies from a Blu-ray player are smooth, but some sources such as a PC experience small amounts of judder. This isn't noticeable to most people. The Z9 has a 120Hz panel which is able to interpolate lower refresh rate content.
The response time of many transitions is worse than most LCDs, resulting in visible blur 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 Z9D uses PWM dimming to reduce the backlight. Due to the high flicker frequency, this isn't really noticeable and motion appears smooth. It is possible to reduce the flicker frequency to 60Hz using the 'MotionFlow' setting and increasing the 'Clearness' slider. This helps to clear up motion blur but produces visible flicker.
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.
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 supports all the common input resolutions, and should be able to properly display all content. It has very low input lag for 4k signals which makes it feel very responsive. Its 1080p input lag isn't as good but should be low enough for most gamers.
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.
- 20% 1080p @ 60Hz @ 4:4:4
- 20% 1080p @ 120Hz
- 20% 4k @ 30Hz @ 4:4:4
- 20% 4k @ 60Hz
- 20% 4k @ 60Hz @ 4:4:4
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.
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.
The Z9D's sound reproduction capabilities are disappointing. While a lot of buyers of this TV will probably place it in a well-equipped home theater, it's still well below other TVs of this stature.
Bad frequency response. Signature is very bass-heavy, and higher frequencies are not well represented leading to issues with clarity. Like most Sony TVs we've reviewed, it also suffers from aliasing at higher volumes.
Very poor distortion performance. THD levels are relatively high at most volumes, but they get especially bad at higher levels.
The Sony Z9D runs Android TV, which tends to be more difficult to navigate than other smart platforms but also has access to the Google Play Store, which has more apps and content than many other smart platforms. The 'Action Menu' button on the remote helps to relieve navigation difficulty by providing a list of commonly used settings so the user doesn't have to navigate to the TV's main settings very frequently. The remote also has a voice search function that can help the user find content directly without having to navigate the TV's interface. Content can also be cast directly to the TV using its 'Chromecast built in' functionality, or played from a USB drive plugged into one of the TV's three USB ports.
The Z9D has no ads in its main interface, though individual apps may have ads. There is an option to opt out of personalized advertising for these ads in apps.
The first row of the home screen is a list of suggested content. In the TV's settings you can opt out of all sources of suggested content until all that remains is a line saying "No recommendations available at this time". However when you opt out of all the listed sources of suggested content and restart the TV, previously unlisted sources may appear, so the process of disabling all the sources must be repeated multiple times.
The included remote is rather large and has a lot of buttons. Fortunately most of the commonly used buttons are clustered around the center direction pad where they are in easy reach; the main exceptions are the input and power buttons which are a little hard to reach. The remote has a microphone for voice search, which works well. Overall the remote is almost identical to those of the X930E and X900E.
Differences between Sizes and Variants
We tested the 65" (XBR65Z9D). For the most part, we expect our review to be valid for the 75"(XBR75Z9D) and 100"(XBR100Z9D) variant as well.
Update 05/05/2017: From the test results that our readers have reported, the 75" model may have a faster response time, resulting in improved motion.
If someone comes across a different type of panel or if their Sony XBR-65Z9D 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.

Compared to other TVs
The Z9D is an exceptional LED TV, but it faces equally exceptional TVs in its price range. It's difficult to justify it when OLED TVs a lot less.
The LG C7 is LG's current entry-level OLED TV. It has exceptional picture quality thanks to its ability to produce perfect blacks, and motion blur is virtually non-existent. It's only real disadvantage compared to the Z9D is its brightness, since it can't get nearly as bright as the Sony. For watching movies in a dark room some people may prefer the brightness of the Z9D, but overall it's very difficult to justify the price difference.
The X930E is one of Sony's high-end models for 2017. It doesn't have quite the stature of the Z9D, but it's a better TV overall. Motion is much better, and it gets equally bright. The Z9D does have a much better local dimming system, which enhances movies in a dark room a great amount. Even with that in mind though, it's a few thousand dollars more expensive, and most people will be happier with the X930E.
The LG B6 is last year's entry-level OLED TV. It's very similar in performance to the C7 from this year, for a lot less money. In general, The B6 is a much better buy than the Z9, since it provides a better experience for a fraction of the price.
The Samsung Q7F is from their QLED line of LCD TVs for 2017. It can produce a significantly wider range of colors than the Z9D, and produces better motion, but it is significantly dimmer and is overall not as good a TV as the Z9D.
