Sony A80K vs A80J Review

Sony A80K is the lowest model of Sony’s 2022 OLED TV lineup and also the successor of the Sony A80K, the lowest model of Sony’s 2021 OLED TV Lineup. Unlike the A95K that already uses QD-OLED, the A80K and A80J use White OLED technology, which has a little weakness in reproducing very bright color and retain to permanent burn-in. Nevertheless, all OLED TVs have great performance in all usage thanks to their impressive picture quality. Meanwhile, that distinguished between Sony OLED TV and OLED TV from other manufacturers is about their its built-in audio system. The Sony A80K and A80J uses a proprietary Sony’s technology called “Acoustic Surface” that utilizes the TV’s screen for producing sound instead of traditional speaker. This is to give an impression that sound object seems like come from more accurate location.

Besides they have excellent picture quality, the Sony A80K and A80J is also maximized for games. They come with some features and technology that help improve their gaming performance like HDMI 2.1, ALLM, and VRR technology. Additionally, both also comes with Google TV 10 as their smart TV platform, which have attractive but simple user interface and tons of apps you can download directly from these TVs. Overall, the Sony A80K and A80J are good TVs for any usage.

In the market, the Sony A80J and A80K are equally available on 3 screen sizes variant, which are 55 inches (XR-55A80K vs XR-55A80J), 65 inches (XR-65A80K vs XR-65A80K), and 77 inches (XR-77A80K vs XR-77A80J).

Dark Room Performance

LED Vs OLED Black Dark Room

As expected from OLED TV, Performance of the Sony A80K and A80J in a dark room is very impressive. Thanks to their infinite contrast ratio, both of them can produce nearly perfect black level and black uniformity. The OLED TVs may not have local dimming because it doesn’t have backlight. But since each of their pixel can emit its own light individually, this makes the OLED TVs has pixel dimming level. This even is equivalent to LED TVS with local dimming that has the number of dimming zone same to the number of pixel or about 8 million dimming zones. As the result, when they are showing black, the pixel in black area will be turned off and there is no light at all that emitted, making black produced by them is nearly perfect. Additionally, this also makes their black uniformity is also nearly perfect. Where ever black is displayed, it will be shown with the same level.

On the contrary, when they are showing highlight in a bright scene, only pixels that is in the bright area is turned on while the others are turn off. The result, highlight in a dark room can be shown excellently without blooming around it, even if they are showing small highlight in a dark scene. Overall, their performance in a dark room is equally great, even if they are showing dark scene.

Winner: Draw

Bright Room Performance

As long as you don’t use them in a very bright room with a lot of lights or sunny windows, their performance is equally good. Their peak brightness is not very bright, which is about 300 nits. For moderately or dim room, their peak brightness may be bright enough to fight the glare. However, their peak brightness is not bright enough to fight tens of glare. This means, in a very bright room with a lot of lights, their peak brightness is not bright enough to fight the glare. And fortunately, both have excellent reflection handling that can help improve their performance in a bright room. But just like other OLED TVs, their peak brightness varies depends on the content. The larger bright area, their peak brightness is dimmer due to their ABL (Automatic Brightness Limiter). Even if they are showing the entire screen is bright, their peak brightness drops to about 150 nits. This could be distracting while watching contents with large bright scene like hockey.

Meanwhile, compare between them, their peak brightness is almost similar. A bit difference between them may be more caused by panel variance. Nevertheless, overall, both can perform well in moderate lighting condition, but in really bright room, their peak brightness is not bright enough to fight the glare.

Winner: Draw

Picture Clarity

Thanks to the Cognitive Processor XR, both of the Sony A80K and A80J can process image signal excellently. Moreover, both also have great 4K up-scaling engine that has been based on AI and also have deep learning machine that can help improve their performance in up-scaling low resolution contents. So, even if the source have 480p resolution like DVD movies, you can still watch them in 4K quality with small details preserved well. And the higher resolution of the source like HD movies with 720p resolution or Blu-Ray movies with 1080p resolution, the 4K image produced will look better with more fine details, as close as native 4K source. Meanwhile, when the source is native 4K content, both can show them without any issue.

Winner: Draw

Side Viewing Angle

OLED vs LED Side Viewing Angle

The image is only an illustration

As we have known, wide viewing angle is one of the major advantages of the OLED TVs, and of course including the Sony A80J and A80K. Black of image looks very consistent, even if viewed from extremely angle. That is not only that, both of them can also show the image with the same brightness level at any angle. However, in maintaining color accuracy, their performance is not as good as QD OLED found on the Sony A95K or Samsung S95B. At certainly angle, which is about 27 degrees off center, color still shift. Nevertheless, color just look washed-out started at about 50 degrees off center and this is fairly wide. So, for you who have wide seating arrangements for watching TVs, both are good TVs for you. Even for you who sits at the side, you will get good viewing quality, not much different who sit in front of the TV.

Winner: Draw

Color Reproduction

Although not as wide as QD-OLED, especially in Rec.2020 color space, with white OLED Panel, both of the Sony A80K and A80J also have outstanding color gamut. Their color coverage in DCI P3 color space where most current HDR content are mastered is nearly perfect. But a bit unfortunately, their color coverage in Rec.2020 where the Next-gen HDR content are mastered is only decent. In Rec.2020 xy color space, they can cover about 72% only and in Rec.2020 uv, they cover about 75% only. This means, when they are showing content that mastered in Rec.2020 like Dolby Vision content, some certain scenes may lose some fine details. And the shortcoming of a TV that use white OLED is that they cannot produce very bright colors. So, bright color cannot be shown as bright as pure white. However, except very bright colors, they are able to show their wide color gamut at their entire brightness color including deep, dark shades of colors.

And just like other models of Sony TVs, both of the Sony A80K and A80J have incredible color gradient. There is only a very little banding that is hard to notice. Their color gradient is even including the best. However, if you feel that banding still bother you, you can enable their “Smooth Gradation” feature, although this may cause some loss of fine details.

Winner: Draw

Motion Handling

Just like other OLED TVs, both of the Sony A80K and A80J also have nearly instantaneous pixel response time. This makes fast moving images looks very clear on their screen with almost no motion blur following fast moving object. However, their nearly instantaneous precisely cause other blur, that is persistence blur. That is not only that, their instantaneous response time also causes low frame rate content like 24p movies appears to stutter. Fortunately, this can be solved by enabling their BFI (Black Frame Insertion) feature or interpolating them to higher frame rate.

As we have known, OLED TV doesn’t have backlight, so they don’t use PWM to dim their screen. As the result, their screen is almost flicker-free, which is great. However, in certain condition, a backlight flicker that match to the frame rate of content is required to improve their motion appearance by reducing persistence blur. And for this purpose, both of the Sony A80K and A80J have an optional BFI mode that can makes their screen flicker at certain frequency. And for this case, the Sony A80J can flicker at both 60 Hz and 120 Hz, which means good for 60 fps and 120 fps content. On the other hand, the Sony A80K can only flicker at 60 Hz, which is disappointing when you play 120 fps games.

Besides native 120 Hz refresh rate panel that allows them can support 120 fps content, both of the Sony A80K and A80J also support Variable Refresh Rate panel. Their VRR technology work well at wide range of refresh rate, which is below 20 Hz to 120 Hz. That is not only that, their VRR technology is also compatible with GSync and HDMI Forum VRR, allowing you to play a game with a compatible device without screen tearing. Sadly, they don’t support FreeSync. This means, their VRR only works with HDMI Forum Device like a PC with new AMD Graphic card or GSync device like Nvidia Graphic Card. However, with older AMD Graphic Card or X Box One,

Winner: Draw

Inputs

As we see on comparison table above, both of the Sony A80K and A80J have 4 HDMI Ports. All of their HDMI ports already support CEC, HDCP 2.2, and HDMI 2.0 Full bandwidth. Additionally, they both also have HDMI ARC that also supports eARC and located on HDMI 3. That is not only that, they also support HDMI 2.1 that allows you to play high quality game supported by the newest game console. However, there are only two ports that supports HDMI 2.1, which are HDMI 3 and HDMI 4. And sadly, their HDMI 3 also serves as HDMI ARC. This means, if you connect your Soundbar or Home theater system to these Sony TVs via HDMI ARC, practically there is only one HDMI 2.1 that is left. And this of course will be inconvenient if you have more than one HDMI 2.1 devices.

Meanwhile, although not as low as the competitors, both of the Sony A80K and A80J also have low input lags in Game Mode. With 60 fps games, their input lags is about 17 ms. This may be not as low as most TVs, but is this still low enough to play any games responsively. Meanwhile, with 120 fps games, their input lag is much lower. No matter the resolution, its input lag is about 9 ms and this of course great for playing any 120 fps games.

A bit difference between them is about the number of their USB ports. As we see on comparison table above, the Sony A80J have 3 USB ports while the A80K have 2 USB ports. Nevertheless, except the number of USB ports, they are equipped with the same inputs outputs like Tuner IN supports ATSC 3.0, Ethernet port, Digital Audio Out (Optical), etc. Both are also equipped with built-in Wi-Fi and Bluetooth for wireless connectivity.

Sony A80K vs A80J Performance

Movies

Just like other OLED TVs, both of the Sony A80K and A80J are great TVs for watching movies in a dark room. Both have infinite contrast ratio, nearly perfect black uniformity, and pixel dimming level. This makes them have incredible performance when used in a dark room. Dark scene looks excellent on their screen with small highlight like subtitle look standout without blooming around it. That is not only that, both also have great 4K Up-scaling engine. So, even if you have DVD movies collection, you can enjoy them close to 4K resolution with small details are preserved well. And the higher resolution of the movies like HD movies, Blu ray movies, or that has native 4K resolution, the 4K images produced will looks more details.  Both of the Sony A80K and A80J can also show movies with judder-free, no matter the source.

But of course, there is no perfect TVs. Although they have incredible dark room performance and great up-scaling engine, but their nearly instantaneous response time can cause movies appears to stutter. To solve this issue, you can enable their BFI mode or interpolate them to higher frame rate. Nevertheless, this cannot be removed completely.

Winner: Draw

Sports

When used for watching sports in a right room, as long as you don’t use them in a very bright room, their performance is equally great. As we have discussed above, both may have excellent reflection handling, but their SDR peak brightness is only about 300 nits. This means, this is only bright enough to fight the glare in moderate lit to dim room, while for a bright room with a lot of lights, their peak brightness is not bright enough.

Nevertheless, ignoring their shortcoming in term of peak brightness, overall, their performance when used for watching sports is great. Both have nearly instantaneous pixel response time and combined to their optional BFI mode, this makes fast sports looks very smooth on their screen without noticeable blur. Additionally, both of them also have great gray uniformity. So, large field in sport that has uniform color like hockey or baseball will look excellent on their screen without dirty screen effect. The other great point is that they have great viewing angle coverage that makes the picture displayed on their screen look consistent, even if you watch from the side. It is good for you who often watch a big game with your family or a group of your friends.

Draw

Video Games

Thanks to their excellent picture quality and great motion handling, you can play any games with excellent picture quality on their screen. Fast paced games looks very smooth on their screen without noticeable blur following fast moving object. Their input lag may be relatively a bit higher than the competitor, whether with 60 fps games or 120 fps games. But their input lag is still low enough to play any games responsively without delay. What your act on your game controller will be still in-sync with what you see on their screen, which is great.

Both of the Sony A80K and A80J also comes with some features that will improve your experience in playing games. Their HDMI ports support ALLM (Auto Low Latency Mode), making them can automatically switch to game mode once the signal form game console or PC is detected. Both also already support HDMI 2.1 that allows you to play newest high-quality game supported by modern game console like PS 6 or XBOX X Series. Meanwhile, for allowing you to play with screen tearing-free, both also support VRR technology that’s compatible with GSync and HDMI Forum. But as we have mentioned, their VRR is not compatible with FreeSync. This means, you cannot the benefits when playing games with FreeSync devices like X Box One or PC with old AMD Graphic Card.

Winner: Draw

HDR Performance

Overall, their HDR performance is good. In showing shadow details of HDR images, their performance is incredible thanks to their infinite contrast ratio, nearly perfect black uniformity and pixel dimming. Black of images can be shown at the level intended by the content creator, allowing them can show dark scene with details. Additionally, highlight in dark scene can also be shown excellently without blooming around it.

In term of color reproduction, their performance is also great. Thanks to their nearly perfect coverage in DCI P3 color space, most current HDR Content can be shown colorfully and vibrantly on their screen. But as we have discussed above, they have only decent color coverage in Rec.2020 where the next-gen HDR content like Dolby Vision are mastered. This means, since they are starting to be produced a lot, this certainly makes them is not very future proof. Fortunately, since most TVS also have decent color coverage in Rec.2020, they are not alone. The other slight shortcoming is that they cannot produce very bright colors. As we have known, the use white sub-pixel on their panel may make them can produce pure white, but on the other hand, this will be desaturated right colors, making them cannot produce bright saturated colors. Nevertheless, this is actually is not a big problem since there is very rarely a content that show an object with very bright color.

Besides they have excellent color reproduction, both of the Sony A80K and A*0J also have incredible color gradient. Its color gradient is even including the best. AS the result, color gradient of HDR images looks very sooth on their screen without noticeable banding.

While both can show shadow details excellently and has excellent color reproduction, HDR peak brightness of the Sony A80K and A80J is only decent. The highest possible HDR peak brightness reached by them is about 700 nits, which is on 2 % white window test. However, like other OLED TVs, the larger area of bright scene, their peak brightness will be dropped by their ABL (Auto Brightness Limiter). This means, the different scene may be shown at different level of brightness. Nevertheless, for OLED TVs, it is still good. Their HDR peak brightness is still bright enough to makes small highlight pop, which is good.

Winner: Draw

Conclusion

As we have discussed a lot above, there is not may improvements offered by the Sony A80K over the A80J predecessor. Whether it is about their design, picture quality, features, or performance, they are not much different. A bit upgrade offered by the A80K is about their built-in audio setup and some features that doesn’t have a significant impact on their performance overall.

Overall, both of the Sony A80K and A80J are great TVS for any usage. As long as you don’t use them in a very bright room with a lot of light of sunny windows, their performance is equally great. Whether you use them for watching movies in a dark room, sports in a bright room, TV Shows, HDR content or playing games, their picture quality and performance is really satisfactory. But of course, there is not a perfect TV. They still have some shortcomings like susceptible to permanent burn-in, decent peak brightness, etc.

So, which is a better choice between them? As we have discussed above, whether about deign, picture quality, features, or performance, they are almost similar overall. But for sure, since the A80K is a newer model, with the same screen size, it is sold more expensive than the A80J. The decision now comes back to you according to your own preferences. But as your consideration, without significant improvement, the A80J older model is better choice since it has cheaper price. Although it is older model, but its picture quality is not much different to A80K that is sold more expensive.
