This TV was replaced by the Sony X90L/X90CL

The Sony X90K/X90CK is an upper mid-range 4k LED TV released in 2022. It sits above the Sony X85K and below the Sony X95K, and it's Sony's lowest-end model in 2022 to feature a full array local dimming feature. It's powered by Sony's Cognitive Processor XR for motion and picture processing. It comes with the Google TV smart platform built-in, which has a user-friendly interface with a ton of apps you can download, and you can use Google Assistant to search for content and easily open your favorite apps. It's available in a wide range of sizes, from 55 to 85 inches, so you can get the one that suits your needs. It has a few extra features for gamers, including HDMI 2.1 bandwidth and variable refresh rate (VRR) support to reduce screen tearing. It's been replaced in 2023 by the Sony X90L/X90CL.

Our Verdict

8.0 Mixed Usage

The Sony X90K TV is great for most uses. It's great for watching movies in a dark room thanks to its high contrast ratio and wide color gamut. It's also good for watching shows or sports in bright rooms with a couple of lights around, but it struggles a bit to overcome glare from bright lights or windows. It also has a narrow viewing angle, so it's not a good choice for a wide seating arrangement. It's great for gaming because it has HDMI 2.1 bandwidth for high-frame-rate gaming, variable refresh rate support, a quick response time, and low input lag for a responsive gaming experience.

Pros
  • Excellent contrast ratio for deep blacks with just a bit of blooming.
  • Excellent SDR peak brightness.
  • User-friendly Google TV smart platform.
  • Colors look vivid and pop.
Cons
  • Struggles opposite really bright windows.
  • Narrow viewing angle.
7.6 TV Shows

The Sony Bravia X90K is good for watching TV shows in a bright room. It has excellent peak brightness, so it gets bright enough to fight glare, but its reflection handling is just decent, and it's best to avoid placing it opposite really bright windows. It upscales lower-resolution content from cable boxes without issue, and the Google TV smart platform makes it easy to stream your favorite content. Sadly, it isn't a good choice for a wide seating arrangement because it has a narrow viewing angle, so the screen looks washed out from the sides.

Pros
  • Excellent upscaling and sharpness processing.
  • Excellent SDR peak brightness.
  • User-friendly Google TV smart platform.
Cons
  • Struggles opposite really bright windows.
  • Narrow viewing angle.
7.5 Sports

The Sony X90CK is good for watching sports in a bright room. Fast-moving balls and players look smooth, thanks to the quick response time. It also performs well in rooms with a few lights around because it has excellent peak brightness to fight some glare, but it struggles if you place it opposite a really bright window. Unfortunately, it isn't a good choice for wide seating areas because it has a narrow viewing angle, meaning the image looks washed out from the sides.

Pros
  • Excellent upscaling and sharpness processing.
  • Excellent SDR peak brightness.
  • Quick response time for smooth motion.
Cons
  • Struggles opposite really bright windows.
  • Narrow viewing angle.

Differences Between Sizes And Variants

We bought and tested the 65-inch Sony X90K, and it's also available in 55-inch, 75-inch, and 85-inch models. The results are valid for the other sizes, but the speakers perform differently on the 55 and 65-inch models than on the larger sizes. There's also an X90CK variant available in 55 and 65 inches at Costco, and it comes with a two-year warranty and two-year subscription to the Bravia Core Streaming service. In Europe, there are the X90K, X93K, and X94K, and although the results are valid for all three variants, the X93K and X94K are closer to the North American X90K because they have a built-in mic. However, the European X90K performs the same; it's just missing the built-in mic.

Finally, there's a smaller variant of this TV known as the Sony X90S and X94S. Both variants are only available in a 50" size and offer very similar performance to the larger sizes. There are a few differences between the X90S and X94S. The X94S comes with a more premium remote, the TV itself has a built-in microphone for hands-free voice control, and it has more picture processing options.

Size Model Number  Costco Model Speakers
50" XR-50X90S - X-Balanced Speaker
55" XR-55X90K XR55X90CK Standard
65" XR-65X90K XR65X90CK Standard

Our unit was manufactured in April 2022; you can see the label here.

Compared To Other TVs

The Sony X90K is a great TV with a few gaming features and great overall picture quality. In a TV market with fantastic high-end TVs and budget models that provide good value, the X90K sits in between and doesn't provide much extra against other TVs like the LG QNED85 or the Hisense U8/U8H.

Also, see our recommendations for the best 4k TVs, the best smart TVs, and the best TVs for watching movies.

Sony X90L/X90CL
55" 65" 75" 85" 98"

The Sony X90L/X90CL is a noticeable improvement over its predecessor, the Sony X90K/X90CK. The X90L gets a lot brighter, especially in HDR, so bright specular highlights stand out better. The X90L also has a much better local dimming feature, resulting in significantly less blooming around bright areas of the screen, deeper blacks, and smoother (but still not great) zone transitions.

Sony X85K
43" 50" 55" 65" 75" 85"

The Sony X90K/X90CK is a higher-end TV than the Sony X85K and is better overall. The X90K has a local dimming feature, which the X85K doesn't have, resulting in better overall picture quality because it displays deeper blacks and gets brighter, so highlights pop more in HDR. The X90K also uses a different processor with a few more features, like the S-Center speaker input, so if you want the best features and performance, the X90K is the better choice.

Sony X80K/X80CK
43" 50" 55" 65" 75" 85"

The Sony X90K/X90CK is a higher-end TV than the Sony X80K/X80CK with better performance. The X90K gets brighter and has deeper blacks, meaning the overall picture quality is better, and it's better for both dark and bright rooms. Also, if you're a gamer, the X90K is a superior choice as it has a higher refresh rate and more features. However, if you have a wide seating area, the X80K has a wider viewing angle that makes the image remain consistent from the sides.

Sony X90J
50" 55" 65" 75"

The Sony X90K/X90CK is the successor to the Sony X90J, and it's not worth the upgrade if you already have the X90J or if you're deciding between the two TVs. The X90K has a wider 1080p VRR range, but other than that the differences are minor.

Sony X900H
55" 65" 75" 85"

The Sony X90K/X90CK is a newer version of the Sony X900H, and the TVs are similar overall. The X90K gets much brighter, so it's better to use in a well-lit room, and it makes highlights pop more in HDR, so it's the better choice if you care about brightness. However, if dark room performance is important to you, the X900H looks better because it displays deeper blacks with better uniformity.

Samsung QN90B QLED
43" 50" 55" 65" 75" 85"

The Samsung QN90B QLED is better overall than the Sony X90K/X90CK. The Samsung gets brighter and has a better local dimming feature, so it displays deeper blacks with real content, meaning it's a better choice for well-lit and dark rooms. If you're also a gamer, the Samsung TV has a few more features like FreeSync VRR support. Lastly, the Samsung is better to use in a wide seating area because it has a wider viewing angle that makes the image remain consistent from the sides.

TCL Q7/Q750G QLED
55" 65" 75" 85"

The TCL Q7/Q750G QLED has some key strengths that outpace the Sony X90K/X90CK, but the Sony is the more stable, balanced, and quirk-free TV overall. The TCL has better contrast and black uniformity, helped by more dimming zones and a better local dimming feature with less noticeable lighting zone transitions. It also gets much brighter than the Sony in HDR and SDR, and they have equally decent reflection handling, so the TCL looks more vibrant both in dark and bright rooms. The Sony, however, is more colorful with its fuller color volume. It's also the more accurate TV overall, as it tracks the creator's intent better with HDR content and is more accurate pre-calibration. And, of course, the Sony TV has vastly better image processing than the TCL, although the TCL does an admirable job of smoothing out macro-blocking from low-quality content.

LG QNED85
55" 65" 75" 86"

The LG QNED85 is better than the Sony X90K/X90CK overall. The LG has a better local dimming feature, so there's much less blooming around bright objects in a dark scene, even though the Sony has better native contrast. The LG also has a wider viewing angle, so it's a better choice for a wide seating arrangement.

Sony X95K
65" 75" 85"

The Sony X95K is a higher-end version of the Sony X90K/X90CK, so it has better overall performance. If you need something for bright rooms with wide seating areas, the X95K has better reflection handling and a wider viewing angle. Even if the X90K has a higher native contrast ratio, the local dimming feature is better on the X95K, so it's also the better choice for viewing content in dark rooms as there's less blooming.

Sony X950H
49" 55" 65" 75" 85"

The Sony X950H and the Sony X90K/X90CKare both great TVs. The X950H is a higher-end TV that delivers better picture quality as it gets slightly brighter and has better reflection handling, so visibility isn't an issue in a bright room, and it performs better in dark rooms as it delivers deeper blacks in real content. If you're a gamer, the X90K is a better choice, as it supports HDMI 2.1 bandwidth and VRR.

Hisense U8/U8H
55" 65" 75"

The Hisense U8/U8H is much better than the Sony X90K/X90CK. The Hisense has much better reflection handling, and it gets significantly brighter, so it's a better choice for a bright viewing environment as it can better overcome glare. The Hisense delivers a more impactful HDR experience, as it gets significantly brighter in HDR and can display a wider color gamut.

Samsung QN85B QLED
55" 65" 75" 85"

The Sony X90K/X90CK and the Samsung QN85B are both great TVs that are good for different scenarios. If you have a bright room with a wide seating area, the Samsung has a wider viewing angle and gets brighter, so visibility won't be an issue even in bright environments. However, if you tend to watch content in a dark room, the Sony delivers deeper blacks with less blooming.

Samsung QN90A QLED
43" 50" 55" 65" 75" 85" 98"

The Samsung QN90A QLED is better overall than the Sony X90K/X90CK. The Samsung delivers better picture quality than the Sony, with deeper blacks, less blooming, higher peak brightness, and a wider viewing angle. It also has FreeSync VRR support if you're a PC gamer. However, if you tend to watch Dolby Vision content from streaming services, the Sony TV supports it, which the Samsung doesn't.

Sony A80K/A80CK OLED
55" 65" 77"

The Sony A80K/A80CK OLED and the Sony X90K/X90CK are different types of TVs, each with strengths and weaknesses. The A80K is better for dark-room viewing as it delivers deeper blacks, and it's also the better choice for wide seating arrangements because it offers a wider viewing angle. If you prefer something for bright-room viewing, the X90K gets much brighter to counteract glare.

Sony A95K OLED
55" 65"

The Sony A95K is better than the X90K/X90CK is almost every way. The Sony’s near-infinite contrast ratio delivers incredibly deep, uniform blacks and lets bright highlights stand out with no blooming. The A95K also delivers a much more impactful HDR experience thanks to its better color volume and wider color gamut. It also has a much wider viewing angle, so if you're using it in a big room, you can move around and still enjoy a consistent image from the sides. The X90K/X90CK does get a lot brighter in SDR, so it’s a better option for watching SDR content in a very bright room.

Samsung QN85C/QN85CD QLED
55" 65" 75" 85"

The Samsung QN85C/QN85CD QLED is better than the Sony X90K/X90CK, except for image processing, where Sony is the market leader. The Samsung has a much better local dimming solution with many more zones, giving it a superior overall contrast ratio with much better black uniformity. It also gets much brighter in SDR and HDR and has a much better viewing angle. The Samsung TV also has four full HDMI 2.1 bandwidth ports versus only two on the Sony, one of which is its eARC port. Of course, the Sony TV has much better low-quality content smoothing and low-resolution upscaling and supports advanced audio and video formats such as DTS and Dolby Vision.

Sony X93L/X93CL
65" 75" 85"

The Sony X93L is a significant step up over the Sony X90K/X90CK. The X93L gets significantly brighter in HDR, so bright specular highlights stand out better. The X93L also has a better anti-reflective coating and a slightly wider viewing angle, but the off-angle viewing isn't good on either model. Finally, the local dimming feature on the X93L is more advanced, with more dimming zones that result in higher contrast, better dark scene performance overall, and significantly less blooming around bright highlights.

Sony X85J
43" 50" 55" 65" 75" 85"

The Sony X90K/X90CK is a higher-end TV than the Sony X85J, so it has a few more features and better performance. If you tend to watch movies in dark rooms, the X90K is the better choice because it has a local dimming feature and has higher HDR peak brightness. However, if you're going to use it in a well-lit room or for gaming, both TVs are similar, so it would be better to get whichever you can find for cheaper.

Hisense U7H [U7, U75H]
55" 65" 75" 85"

The Hisense U7H and the Sony X90K are similar TVs that perform slightly better than each other in different situations. The X90K is generally better for gaming due to its faster response time, so there is less blur behind quick-moving objects on screen, but if you’re looking for 1440p @ 120Hz support, the Hisense is the better option since the Sony lacks that ability. When it comes to watching movies in a dark room, the Hisense is the better option since it has better contrast, better black uniformity, and gets brighter in HDR, so highlights pop more than on the Sony. If you regularly watch low-quality and low-resolution content, the Sony is much better for that due to its better processing capabilities.  

Sony A80J OLED
55" 65" 77"

The Sony A80J OLED and the Sony X90K are different types of TVs due to their different panel types. If you often watch content in a dark room, the A80J is the better choice as its OLED panel delivers deeper blacks. However, if you want to use it in a well-lit room to watch content in SDR, the LED panel of the X90K gets much brighter, so it fights glare better.

Sony X95J
65" 75" 85"

The Sony X95J is higher-end than the Sony X90K/X90CK, meaning it provides better picture quality. If you want the best picture quality, especially for a wide seating arrangement, the X95J is the better choice because it has a wider viewing angle and better local dimming. However, if you want to spend a bit less, the X90K is also a great choice for dark room viewing because it has a better native contrast ratio, so blacks look deeper.

LG QNED80 2022
50" 55" 65" 75" 86"

The Sony X90K/X90CK is better than the LG QNED80. The Sony is much better for watching movies in HDR or SDR because it displays deeper blacks and its local dimming feature is significantly better. It also gets brighter in HDR, allowing colors to look vivid and highlights to stand out. While the Sony is better overall for gaming due to its faster response time, the LG has lower input lag for a more responsive feel.

Hisense U8G
55" 65"

The Hisense U8G and the Sony X90K/X90CK are great TVs with a few differences. The Hisense gets brighter and has a better local dimming feature, meaning its overall picture quality and bright and dark room performance are better. The Hisense also displays more colors, and smaller highlights pop more if you watch HDR content. They have the same gaming features, but the Sony doesn't have the same motion issues as the Hisense, if that's an issue for you.

Stand

The Sony X90CK has metal feet as the stand, and there are two positions you can put it in. The short position makes the TV sit very close to the table, but you can also raise the feet to place a soundbar in front without blocking the screen. The stand supports the screen well with minimal wobble, even in the raised position.

Footprint of the 65-inch TV: 46.3" x 13".

  • Height to the bottom of the screen in lower position: 1.54" (3.9 cm)
  • Height to the bottom of the screen in raised position: 3.31" (8.4 cm)

The North American variant has these two stand configurations, but you can also adjust the stand to a narrow position on the Sony X90K, X93K, and X94K models in Europe.

Build Quality

The Sony Bravia X90CK has good build quality. It's well put-together, and there aren't any obvious issues with it. The bezels are uniformly attached to the screen, and the feet hold the TV well. There's some flex on the back panel near the inputs, which isn't much of an issue, and the rest of the back panel doesn't flex as much.

The panel has two dark spots that you can see in the Gray Uniformity photo, which is likely caused by pressure during assembly.

Blooming

The Sony X90K Series has decent blooming handling. Due to the relatively large size of each zone, bright highlights create a large zone of blooming around them, especially since the TV seems to be averaging out bright highlights across more zones than necessary to reduce the harshness of the blooming. The amount of blooming also varies considerably depending on the content; you can see a few examples below:

Unfortunately, zone transitions are easily noticeable on this TV. There's a noticeable flicker as bright highlights move across the screen and zones turn on, especially with fast-moving content. It can't keep up with really fast content, either, resulting in a trailing halo behind bright objects, and the leading edge is darker. If you're sensitive to lighting zone transitions, check out the Samsung QN85C/QN85CD QLED, which is much better in this regard. The replacement model to this TV, the Sony X90L/X90CL, has more dimming zones, and the zone transitions are less noticeable.

The EOTF follows the target curve incredibly well, meaning that most content is displayed at the correct brightness level in HDR. Shadow details are displayed incredibly well, with no noticeable black crush. Midtones are slightly dimmer than they should be, but it's not a noticeable difference, and there's a fine roll-off near the TV's peak brightness, ensuring that fine details in bright scenes are preserved.

The Sony X90K has decent accuracy before calibration. Most colors are accurate enough that you won't see any issues, but the color temperature is a bit cold, giving the screen a bit of a blue tint. Also, the white balance is off, particularly with shades closer to pure white. Luckily, gamma follows the 2.2 target well, so scenes appear at their correct brightness.

This TV has an optional backlight strobing feature, commonly known as black frame insertion. It's meant to flicker at 120Hz, which causes image duplication, but it has a strange pattern to match the standard 720Hz flicker of the backlight. It doesn't flicker at 60 fps for 60Hz content, which also causes image duplications.
