The Sony A90J OLED is an amazing 4k TV from Sony's Master Series. Like other OLEDs, it delivers unparalleled picture quality thanks to its self-emitting pixels, which produce perfect blacks and a near-infinite contrast ratio. While its HDR brightness is only decent relative to LED TVs, it still delivers a great HDR experience thanks to its wide color gamut and high contrast ratio. It also has a near-instantaneous response time for clear motion, and it supports variable refresh rate (VRR) technology to reduce screen tearing, but it doesn't support FreeSync. On the upside, it has two HDMI 2.1 ports, eARC, and Dolby Vision support. It also has wide viewing angles and superb reflection handling. Sony released a new model with the same name, the Sony A90K OLED, in 2022. It's not a direct replacement, though, as it's only available in a 42" and 48" size.
The Sony A90J is an amazing TV for mixed usage. It delivers exceptional picture quality for movies and TV shows, and its near-instantaneous response time results in smooth motion for sports and video games. While it doesn't get as bright as an LED TV, it's bright enough to bring out most highlights in HDR, aided by its near-infinite contrast ratio. Unfortunately, there's a risk for permanent burn-in, though it shouldn't be an issue if you watch varied content.
The Sony A90J is a fantastic choice for watching movies. With its near-infinite contrast ratio, it can produce deep, inky blacks with perfect uniformity. It has no issues upscaling lower resolution content, like DVDs or Blu-rays, and it removes 24p judder from any source. Unfortunately, the extremely quick response time can cause stuttering in lower frame rate content like movies.
The Sony A90J is great for watching TV shows. It has fantastic reflection handling, so glare shouldn't be an issue, despite its lower brightness. The Google TV platform is also smooth and lets you access all your apps and shows from one smart hub. It has wide viewing angles, which is great if you watch TV at an angle. Unfortunately, it may be susceptible to permanent burn-in with static elements like a news banner or logo.
The Sony A90J is excellent for watching sports. Its near-instant response time results in smooth motion, and it has a Black Frame Insertion feature to further reduce blur. It also has wide viewing angles, which is great for watching the game with friends. While it isn't the brightest TV, it has fantastic reflection handling, so glare shouldn’t be an issue. That said, there's a risk of permanent burn-in, especially with static elements like a score box or channel logo.
The Sony A90J is fantastic for playing video games. It has a near-instantaneous response time that results in exceptionally clear motion, and its exceptionally high contrast ratio is great for gaming in the dark. It also has great gaming features like HDMI 2.1 bandwidth and VRR support, but its input lag is a bit higher than some other TVs.
The Sony A90J is excellent for watching movies in HDR. It has a wide color gamut, and its perfect black levels create a near-infinite contrast ratio, which helps make highlights pop, despite the lower brightness that's typical of OLEDs. That said, the ceiling in brightness means that the very brightest details may be lost.
The Sony A90J is fantastic for HDR gaming thanks to its extremely fast response time and perfect black levels. While it doesn't get as bright in HDR as most LED TVs, it's among the brightest OLEDs we've tested. It also has a wide color gamut. It also supports VRR to reduce screen tearing, but sadly you can't play 4k games at 120Hz in Dolby Vision.
The Sony A90J is an excellent TV to use as a PC monitor. It has a low input lag and exceptional response time. It can also display proper chroma 4:4:4 at most resolutions, and its wide viewing angles ensure the image stays accurate at the edges when sitting up close. Unfortunately, it doesn't support 1440p @ 120Hz. There may also be more risk for burn-in with static elements like a desktop user interface.
We tested the 55 inch Sony A90J OLED (XR-55A90J), which is also available in 65 inch (XR-65A90J) and 83 inch (XR-83A90J) sizes. The results are also valid for those models. The model codes are the same in Europe and the UK.
If you come across a different type of panel or your Sony A90J doesn't correspond to our review, let us know, and we’ll update it. Note that some tests, like gray uniformity, may vary between individual units.
Our unit was manufactured in February 2021, and you can see the label here.
The Sony A90J OLED is an amazing overall TV. It’s Sony’s brightest OLED yet, especially when it comes to HDR, and it’s a very well-built TV. That said, it also comes with a very premium price tag, and while it has gaming features like HDMI 2.1 bandwidth and VRR support, other OLEDs are better for gaming, like the LG C1 OLED.
The LG C2 OLED and the Sony A90J deliver a nearly identical experience overall, but the LG is slightly brighter with some scenes. The LG also has more advanced gaming features, including HDMI 2.1 bandwidth on all four HDMI ports. On the other hand, the Sony TV has better processing, with much better tone mapping in HDR and better motion handling, so it's a better choice for movie lovers who care about an accurate image.
The Sony A95K OLED is an improvement over the Sony A90J OLED, especially with watching HDR content. The A95K uses new QD-OLED technology, which is a type of OLED that allows it to display more vivid colors and brighter highlights than the A90J. However, if you want to use your TV in a well-lit room, the A90J maintains perfect black levels in well-lit rooms, as the black levels raise on the A95K when there's ambient lighting.
The Sony A90J OLED and the LG G2 OLED are very similar overall, but the LG is slightly better for most users. The LG is brighter, especially when displaying small, bright highlights in HDR, and it has better gaming features. The Sony has better gradient handling and much better tone mapping, so it's a better choice for anyone who cares about an accurate image.
The Sony A90J OLED is a higher-end TV than the Sony A80K OLED, so it performs a bit better overall. The A90J gets slightly brighter in HDR, delivering a more impactful HDR experience. That's the main difference between the TVs, so if you're after the best picture quality, stick with the Sony.
The Sony A80J OLED and the Sony A90J OLED are very similar TVs overall, and both offer stunning picture quality in a premium, well-built package. That said, the A90J uses Sony's new heatsink technology, which allows it to get brighter in HDR, although the difference is relatively small. The A90J also has a better remote with motion-activated backlighting. The other big difference is that the A90J is available in 55, 65, and 83 inch sizes, while the A80J is available in 55, 65, and 77 inch sizes. If none of these are dealbreakers, the A80J is still an excellent choice that performs about the same as its more expensive sibling.
The Samsung S95B OLED is a better TV than the Sony A90J OLED for most users. The Samsung TV gets a bit brighter in general, and colors are significantly brighter thanks to its new QD-OLED display technology. On the other hand, the Samsung TV sacrifices accuracy in HDR for a more vivid, impactful image, so if image fidelity matters to you, the Sony is a better choice.
The Sony A90J OLED is a bit better than the Sony A90K OLED, but the differences are very minor. The A90J is a bit brighter than the new model, meaning it can handle a bit more glare, and bright highlights in HDR stand out a bit more. Although sharing the same model name, the A90K isn't a direct replacement for the A90J, as they're available in different sizes. The A90J is available in a 55", 65", and 83" size, while the A90K is only available in 42" and 48" sizes.
The LG C1 OLED and the Sony A90J OLED are both amazing TVs. They each have OLED panels with near-infinite contrast ratios and perfect black levels. That said, the Sony can reach higher peaks of brightness in both SDR and HDR. The LG, however, is the better option for gaming since it has FreeSync support and lower input lag, while the Sony is G-SYNC compatible.
The Sony A90J OLED and the Sony A8H OLED are very similar TVs overall. The biggest difference is that the A90J has two HDMI 2.1 ports, which is great if you plan on using it for the latest gaming consoles, while the A8H doesn't have any. Otherwise, they both deliver the same exceptional picture quality and performance that most OLEDs do, thanks to their ability to turn off individual pixels and their near-instantaneous response times.
The LG G1 OLED and the Sony A90J OLED are similar and fantastic TVs. They each deliver a near-infinite contrast ratio for deep blacks. The LG has the new evo OLED panel, allowing it to get brighter than other OLEDs, and while the Sony isn't advertised to have the evo panel, it has about the same brightness as the LG. The main difference is that the LG is designed to sit flush against a wall and doesn't come with a dedicated stand like the Sony.
The Sony X90J and the Sony A90J OLED are very different performance-wise because they don't use the same panel type, but they have similar features. The A90J is an OLED TV that delivers better picture quality because it has a near-infinite contrast ratio, and it can produce perfect blacks by turning the pixels off. It has wider viewing angles and better reflection handling, but it doesn't get as bright, so it might not overcome intense glare. The A90J has near-instantaneous response times, making it better for fast-moving content like sports or gaming, but it also causes low frame rate content like movies to stutter. Both TVs have a 120Hz refresh rate, HDMI 2.1 support, and run on Google TV. Lastly, the A90J is susceptible to permanent burn-in, whereas the X90J is immune.
The Sony A90J OLED and the Sony X95J use different panel types, each with strengths and weaknesses. The A90J uses an OLED panel, which delivers true inky blacks with perfect black uniformity, whereas the X95J uses an LED backlight. The X95J is a lot brighter, but the A90J has better dark room performance, better uniformity, and better viewing angles. The A90J also has a nearly instantaneous response time, so it's a better choice for gamers.
The Sony A90J OLED and the Samsung QN90A QLED are both excellent all-around TVs, but they use different panel types. The Sony is an OLED, so it has perfect blacks and an infinite contrast ratio. The Samsung, on the other hand, is an LED TV, and its use of Mini LED backlighting allows it to get exceptionally bright. The Sony may be a better option if you prioritize movies and picture quality, but the Samsung is a better option for gaming since it has lower input lag.
The Sony A90J OLED and the LG CX OLED perform very similarly overall. Like all OLEDs, the perfect blacks and near-instantaneous response times on both deliver exceptional picture quality and performance. The biggest differences are in design and features. The Sony feels a little bit more premium overall, but the LG comes four HDMI 2.1 ports, as opposed to the two on the Sony. All in all, they're both amazing TVs.
The Sony A90J OLED is better than the Samsung QN900A 8k QLED. While it can't display an 8k signal like the Samsung, there isn't much 8k content yet. Plus, the Sony is an OLED, so it has a near-infinite contrast ratio that can display perfect blacks with no blooming. The Samsung uses a VA panel but has low native contrast. While it's improved heavily by local dimming, the local dimming feature produces noticeable blooming. The biggest advantage of the Samsung is that it gets significantly brighter, so it's a little better suited to very bright rooms.
The Sony A90J OLED and the Sony A9G OLED are both excellent OLED TVs. They can both turn off pixels individually to produce an infinite contrast ratio and perfect black levels, which is great for watching movies and other content. If you're a gamer, though, the A90J has a bit of an edge because it supports HDMI 2.1 and has a bit less input lag. It also gets a bit brighter in HDR if you watch a lot of HDR content.
The Sony A90J OLED and the LG B2 OLED are similar TVs. The LG is a better choice if you're a gamer because it has lower input lag. Also, if you want to use the TV in a well-lit room, the LG gets brighter. However, if you watch movies, the A90J is a better TV because it has better image processing and improved gradient handling, so movies appear more life-like.
The LG GX OLED and the Sony A90J OLED are both high-end, well-designed OLED TVs. If you want something that looks sleek and will sit absolutely flush against the wall, the LG is one of the thinnest TVs we've tested, designed to look like a piece of art on your wall. Otherwise, the two perform very similarly, delivering the same perfect black levels that all OLEDs do. That said, the Sony also gets a bit brighter in HDR and is technically capable of hitting an exceptionally high peak brightness in 'Vivid' mode, but not for sustained periods of time.
The Sony A90J OLED and the Hisense U8G use different display panels, each with strengths and weaknesses. The Sony looks best in a dark room, as the OLED panel displays perfect blacks, with no blooming or uniformity issues. The Sony also has much better viewing angles, making it a better choice for a wide seating arrangement. Unfortunately, OLED technology comes with some inherent risks, including the possibility of permanent burn-in. The Hisense, on the other hand, is much brighter, and it supports some of the latest gaming features, including support for a variable refresh rate.
The Sony A90J looks similar to other high-end Sony OLEDs but with a newly designed stand that offers more adjustability. With its thin bezels and metal accents, it looks sleek and premium and is sure to make an impression in any living room.
The stand can be set up in one of two ways, either with the feet flat, bringing the TV flush against the table, or raised up to give you space for a soundbar. There's also a third configuration where the feet face inward to make a smaller footprint, but it's only available on the 83 inch variant.
Footprint of the stand: 51.1"x12.5" (standard position) or 45.3"x12.5" (soundbar position)
The Sony A90J doesn't have much in the way of cable management except for some paneling that covers a portion of the cables and an included cable tie, but overall it looks fairly clean. The back of the panel itself is metal while the rest is plastic with vertical ridges.
The Sony A90J is quite thin overall and should look great when wall-mounted, although not all of the inputs are side-facing and may be hard to reach.
The build quality of the A90J is superb. It feels incredibly sturdy in either of the stand positions, with no wobble or flex. All in all, it's a very solid-feeling TV, as expected from a high-end model like this.
The Sony A90J has a near-infinite contrast ratio thanks to its OLED panel, which can produce perfect blacks. They look deep and inky, especially in a dark room, ideal for movies.
Update 04/23/2021: We retested the brightness after warming up the TV for 100 hours; it was at 193 hours of uptime when we retested it. We also checked the brightness with other Picture Modes. 'Cinema' isn't as bright as 'Custom' because it has a Real Scene Peak Brightness of 248 nits. 'Vivid' is also still brighter as we measured a peak of 780 nits in the 10% window. Overall, it doesn't seem that warming up the A90J has a significant impact on the brightness. These are our results, using the same settings as originally tested in the 'Custom' Picture Mode:
The Sony A90J has okay SDR brightness. It’s a bit dim in real scenes compared to an LED TV, for instance, and the Automatic Brightness Limiter (ABL) causes scenes with large areas of brightness to dim overall, so the brightness isn’t the most consistent across different scenes. It's a bit brighter than the new, smaller sizes of the Sony A90K OLED.
We measured SDR brightness after calibration, using the ‘Custom’ Picture Mode, the ‘Expert 1’ Color Temperature, Peak Luminance set to ‘High’, and Brightness at max.
To get the brightest possible image, you can set the Picture Mode to ‘Vivid’ and keep all of the default settings. We were able to measure 680 nits in the 2% window using these settings, but we don’t recommend it because it may negatively affect picture quality. If you want a high-end TV that gets much brighter, check out the Samsung QN900A 8k QLED.
The Sony A90J doesn't have a backlight, but thanks to its near-infinite contrast ratio, it's equivalent to a perfect local dimming feature. There's no blooming around bright objects in dark scenes, and bright white pixels are displayed perfectly even if they're surrounded by black pixels. We still film these videos on the TV, so you can see how it performs and compare it with a TV that has local dimming.
There's no difference in dark scene behavior between the calibrated picture modes and 'Game' mode.
Update 04/23/2021: We retested the brightness after warming up the TV for 100 hours; it was at 193 hours of uptime when we retested it. Once again, warming up our unit of the A90J doesn't significantly impact the HDR brightness. We also measured the brightness in the 'Vivid' Picture Mode. It reached 777 nits in the Real Scene Highlight and 976 nits in the 10% window. These are our results, using the same settings as originally tested in the 'Custom' Picture Mode:
The Sony A90J has decent HDR brightness. It’s better than most OLEDs we’ve tested thus far, although it doesn't come close to the brightest LED TVs like the Samsung QN90A QLED. Still, the overall brightness of scenes is on-target and can bring out most highlights. As with SDR, however, there isn’t much consistency across scenes with different luminance levels. Very large areas of brightness are dimmer. It performs similarly to the LG G1 OLED, which has the new evo panel, but it's not as bright as the LG G2 OLED.
We measured HDR brightness before calibration, using the 'Custom' Picture Mode, with Brightness set to max, Contrast at '90' (by default), Color Temperature set to 'Expert 1', and using the 'Gradation Preferred' setting in the HDR Tone Mapping menu.
In 2021, there’s a new settings menu called HDR Tone Mapping. Our measurements use the 'Gradation Preferred' setting, but it may be helpful to note that while the 'Gradation Preferred' setting results in a more accurate EOTF, the 'Brightness Preferred' setting lets you get a brighter image without having to make too many other adjustments. If you want to see the difference these settings make, you can see the 'Brightness Preferred' EOTF here and the EOTF with HDR Tone Mapping disabled here.
To make HDR brighter, set Advanced Contrast Enhancer to 'High', Peak Brightness to 'High', set Brightness, Contrast, and Gamma to max, and 'Brightness Preferred' in the HDR Tone Mapping menu. These settings result in this EOTF. We should also note that we were able to adjust the settings to achieve a peak HDR brightness measurement of 1291 nits in the 2% window, which is close to the 1300 nits that early reviews claimed. However, the screen got very hot and quickly dropped back down to a lower luminance level, so while the TV is technically capable of hitting an exceptionally high peak brightness for an OLED, realistically speaking, you won’t get that kind of brightness with real content using ideal settings.
Update 04/23/2021: We retested the brightness after warming up the TV for 100 hours; it was at 193 hours of uptime when we retested it. Warming up the TV made the Real Scene Highlight brighter, but it didn't impact the test windows by much. These are our results in the 'Game' Picture Mode with the Brightness Preferred setting enabled:
The HDR brightness in 'Game' mode is very similar to the HDR brightness outside of ‘Game’ mode. It’s hard to even tell the difference when switching between the two. That said, the brightness measured slightly less bright than outside of 'Game' mode, especially the real scene brightness. As with SDR, you can set HDR Tone Mapping to 'Brightness Preferred' to get a slightly brighter image, though we expect that this will depend highly on the content.
We took these measurements using the same settings as our regular HDR brightness test, except in the ‘Game’ Picture Mode.
The Sony A90J has superb gradient handling. It looks really good, despite some minor banding in the grays and greens. If you notice banding and it bothers you, you can enable Smooth Gradation to help smooth out gradients, although it may produce artifacts.
The Sony A90J has excellent gray uniformity, but this may vary between units. The screen looks very uniform overall with almost no dirty screen effect, and we didn’t notice any banding or issues in near-dark scenes, although this can occur with more extensive use.
Note: A few owners have reported seeing a grid-like pattern on their TV in uniform scenes. It's usually not noticeable with real content, but this is a manufacturing defect; if you see it on yours, you should exchange it.
Like all OLEDs, the Sony A90J can completely turn off individual pixels to achieve perfect black uniformity.
The Sony A90J has excellent viewing angles, but they're not quite as good as the LG A1. They're wide enough that the image won't look washed out or inaccurate if you watch at an angle.
The Sony A90J has fantastic reflection handling. It diffuses both direct and indirect reflections very well, so glare shouldn’t be an issue, especially in more moderate lighting conditions.
The Sony A90J has amazing out-of-the-box color accuracy, though this can vary between units. Colors and white balance are both excellent with few inaccuracies. The color temperature is quite close to our 6500K target, but it’s on the cooler side. Lastly, gamma follows the target very well, with only the brightest scenes appearing a bit brighter than they should.
Update 05/19/2021: We downloaded the Calman for Bravia app to see if it works for calibration. Having the app on the TV itself doesn't do anything and you need Calman downloaded on a PC. Also, only the 2018 version of Calman and newer works. With it, you can access a 20-point calibration and Custom Pro Picture Modes.
After calibration, the Sony A90J has exceptional color accuracy. Any remaining inaccuracies shouldn’t be noticeable to the naked eye, and the color temperature is very close to the target. Gamma is practically perfect. The TV was also very easy to calibrate. You can see our recommended settings here.
Like all OLEDs, the Sony A90J uses a WRGB sub-pixel layout, where the pixels are never all on at the same time. While this TV is said to be able to brighten all four pixels at once to achieve a higher peak brightness, we never saw all four sub-pixels lit at the same time, even when we recorded 1291 nits. You can see some of the blue sub-pixels lit up in this photo.
The Sony A90J has an excellent color gamut. It's wide enough for HDR content and has near-perfect coverage of the commonly used DCI P3 color space. Its coverage of the wider Rec. 2020 is only decent, though.
The color volume is decent. It only really struggles a bit with very bright colors, which aren't as bright as QD-OLED displays, like the Samsung S95B.
There’s a bit of temporary image retention immediately after playing a high-contrast video for 10 minutes, but it disappears quickly. Keep in mind that image retention can vary between units.
Even though the Sony A90J OLED is likely less prone to burn-in than older OLED panels, there's still a risk. OLED panel technology has significantly advanced since our real world burn-in test, which used 2017 models, so we don't really know just how likely it is that these TVs will experience burn-in. We'll be starting a new burn-in test shortly to try to determine how effective each of these new panel technologies are at reducing the risk of burn-in, so our estimated burn-in risk score may change.
The Sony A90J has a near-instantaneous response time, like all OLEDs. For the most part, motion looks smooth with very few artifacts. Nevertheless, you may still notice persistence blur caused by the way our eyes track movement. This is also why our photo is blurry despite the fast response time.
Because it's an OLED, the Sony A90J doesn't have a backlight, but it can still emulate the Pulse Width Modulation (PWM) of LED TVs by turning its pixels on and off. For that reason it isn't flicker-free; the slight dip in brightness that you can see in the chart every 8 ms is due to the TV's 120Hz refresh rate.
The Sony A90J has an optional Black Frame Insertion (BFI) feature, which can help reduce motion blur by inserting black frames into content at regular intervals, typically matched with the frame rate of the content. For a BFI frequency of 120Hz, you should set Motionflow to 'Custom' and set Clearness to '1' or '2'. For 60Hz, set Clearness to '3' (max).
The Sony A90J can interpolate lower frame rate content up to 120fps to make motion look smoother, which is also known as the 'Soap Opera Effect'. It performs fine during slower scenes, but there's a fair number of artifacts in busier scenes or panning shots. To use it, set Cinemotion to 'High' and Smoothness to max.
Due to the TV's fast response time, low frame rate content can appear to stutter since each frame is held on longer. Motion interpolation can help if stutter bothers you.
Update 05/14/2021: We retested the TV to see if there's judder with BFI enabled via a 60p source. With the Clearness setting at 'Max' the BFI flickers at 60Hz and there's judder; setting it to '2' makes the BFI work at 120Hz and reduces the judder, and '1' removes it completely.
Unlike the LG A1 OLED, the Sony A90J can remove judder from all sources. You don't need to enable any additional settings for native 24p content. For 24p content via 60p/i or via native apps, set Cinemotion to 'High' and Motionflow to 'Custom' but leave the sliders at 0.
Update 08/30/2022: With firmware version PKG6.5942.0698NAA released in July 2022, there aren't any issues with 1080p signals using VRR below 120 fps. There were some issues with the screen going black before this firmware version, so if you notice anything, just make sure to update the TV to the latest firmware.
Update 03/04/2022: Sony released an update to include VRR support with firmware PKG6.5660.0668NAA.
The Sony A90J has VRR support after a firmware update, and it works without any issue on the Xbox Series X for a tear-free gaming experience. However, it doesn't support FreeSync at all, and because the Xbox Series X supports both HDMI Forum VRR and FreeSync, it's confirmed that it supports HDMI Forum VRR natively.
It's also G-SYNC compatible, but there are some issues with it. It removes tearing with 4k @ 120Hz signals from the NVIDIA RTX 3060 graphics card, but at first, the screen flickered until the TV and PC were both reset. Still, there wasn't any screen tearing or flicker in Destiny 2 with a 4k @ 120H signal. Despite there being a few issues depending on the signal, VRR reduces screen tearing when it works properly.
Update 03/04/2022: Sony released an update to include VRR support with firmware PKG6.5660.0668NAA. However, like other TVs, we couldn't get proper VRR input lag readings because the TV kept crashing. We experienced the same issue with the Sony X90J and the Sony X85J, and we're looking into it.
Update 07/08/2021: We retested the input lag with the latest firmware, PKG6.3770.0471NAA. The 4k @ 120Hz input lag has increased by about 3ms.
The Sony A90J has a low input lag, although it's slightly higher than competing high-end models and rises significantly outside of 'Game' mode. To get low latency, you can use either the 'Game' or 'Graphics' Picture Mode, though we recommend 'Game' mode to get the lowest latency for gaming.
The Sony A90J supports most common resolutions, including proper 4k @ 120Hz. However, it can't do 1440p @ 120Hz. We also had trouble displaying proper chroma 4:4:4 in 1440p on our test laptop, as text looked blurrier than it should have, but this only occurred on the laptop and not other PCs. Our screen also blacked out when trying to display 4:4:4 at 1440p @ 120Hz on the laptop, so we couldn't confirm if it skips frames or not. For chroma 4:4:4 to work properly, 'Enhanced Format' must be enabled in the HDMI Signal Format menu and Picture Mode set to 'Game' or 'Graphics'. 'Enhanced Format' is also required to achieve full bandwidth signals.
Update 03/04/2022: After a firmware up to version PKG6.5660.0668NAA, the Sony A90J now supports both VRR and ALLM.
The Sony A90J supports most but not all resolutions for the latest gaming consoles since it doesn't support 1440p @ 120Hz. We received comments suggesting that the A90J has more banding issues in HDR at 4k @ 120Hz than in SDR. We retested the TV to check for this. With Destiny 2 on the Xbox Series X, there was a bit more banding in HDR in parts of the sky or the main menu, but you'd have to look for it to notice. On the PS5, we tested with Call of Duty: Cold War, and the visibility of banding depended highly on the map. With some maps, there was noticeable banding in both SDR and HDR, although it was worse in HDR. In others, the banding was more minimal and only noticeable in clouds, for instance, in HDR. With Destiny 2 on the RTX 3070, however, we didn't notice an appreciable difference between SDR and HDR when it comes to banding. It leads us to believe that while there is more banding in HDR than in SDR at 4k @ 120Hz, it's highly dependent on the content.
The Sony A90J supports eARC, which allows the TV to pass high-quality audio formats to an external receiver over HDMI. To use it, enable 'eARC Mode', then set Digital Audio Out to 'Auto 1' and Passthrough to 'Auto'.
Update 07/20/2021: We retested the frequency response and distortion with the feet in the lowered position. The frequency response improved slightly, and there's a lot less distortion.
Update 07/08/2021: We retested the frequency response with the latest firmware, PKG6.3770.0471NAA. The low-frequency extension is a bit lower, resulting in a slightly better overall frequency response, but there's a bit more compression.
Update 05/28/2021: We listened to the speakers again to make sure our testing is correct. With Acoustic Auto Calibration enabled, we listened to a variety of content, including music and movies like Captain America: Civil War and Space Jam. It's nowhere near as good as a dedicated soundbar and there's nothing special about the speakers. If we were to subjectively assign a score, it would be in line with the testing results.
The Sony A90J has a decent frequency response. This is mostly due to its lack of bass. While dialogue should sound okay and the TV gets very loud, there's also a lot of compression at higher volumes, resulting in pumping.
Update 07/20/2021: We retested the frequency response and distortion with the feet in the lowered position. The frequency response improved slightly, and there's a lot less distortion.
Update 07/08/2021: We retested the distortion with the latest firmware, PKG6.3770.0471NAA. The distortion performance is slightly better.
Distortion performance is decent. There isn't much distortion at most volume levels, but it gets quite distorted at max volume.
The Sony A90J runs on Google TV, which replaces Android TV. It's very similar to Android but improves upon it in a couple of ways. For one thing, it's very smooth and fairly easy to navigate, with no bugs or issues. It also streamlines everything by letting you log in to all of your most-used apps from the smart hub, where it then organizes all your content.
Unfortunately, there are ads in the app store and on the home page, which you can't disable. You can opt-out of some suggested content, but you can't get rid of suggested content completely.
The app store has a wide range of apps available to download, and they run smoothly.
Update 05/14/2021: We retested the TV to check if it still works with the Android TV app, even though it now has Google TV. It works perfectly and you get the same features as you did with Android TV, like voice control.
The Sony A90J has a similar remote to other Sony OLEDs like the Sony A9S OLED. It has shortcut buttons to the top streaming apps and YouTube, as well as a dedicated Google Assistant button that activates its voice command feature. You can use voice commands to change inputs, adjust certain settings, search within apps, and more. It can also be used as a universal remote, although it may depend on your country and particular device. The remote also has new, motion-activated backlighting, so you can see the buttons in the dark.
There's a single button on the back of the left side. Press it to move through options and hold it to select.
