The Sony X80J is an entry-level 4k TV from Sony's 2021 lineup. It lacks many features you'd find on higher-end TVs but performs as expected for a lower-tier IPS-type model. With a low contrast ratio, its ADS panel has a low contrast ratio, so blacks look gray in a dark room, and it doesn't have a local dimming feature to improve black levels. That said, it has good wide viewing angles, and it gets decently bright, meaning glare won't be an issue in moderately-lit rooms. While it has a wide color gamut for HDR content, it simply doesn't get bright enough to bring out highlights in HDR, so the overall HDR experience is limited. It's fairly basic in gaming features, without variable refresh rate (VRR) or Auto Low Latency Mode (ALLM), and its HDMI ports are limited to HDMI 2.0 bandwidth, but casual gamers should be pleased with its quick response time and low input lag. Like other 2021 Sony TVs, it comes with Google TV, which replaces Android TV. The new interface is fast, easy-to-use, and has a huge selection of streaming apps.
Our Verdict
The Sony X80J is okay for mixed usage. It looks best in bright rooms, and its wide viewing angles are great for wider seating arrangements. However, it's disappointing for watching movies or gaming in a dark room, and its HDR performance is lackluster, as it has low contrast and no local dimming feature to improve dark room performance. Competitive gamers will be disappointed by its lack of advanced gaming features, but its low input lag and fast response time should be fine for casual gaming.

The Sony X80J is inadequate for watching movies in a dark room. It has a mediocre contrast ratio, so blacks look more like gray in the dark, and it doesn't have a local dimming feature to improve dark room performance. Unfortunately, it can only remove judder from sources that can send a 24Hz signal, like Blu-ray players, but not from 60Hz sources like a cable box. On the upside, it has no issues upscaling lower resolution content.

Differences Between Sizes And Variants
We tested the 55 inch Sony X80J (KD-55X80J), which is also available in 43, 50, 65, and 75 inch sizes. For the most part, we expect our results to be valid for those sizes, except for the 50 inch, which uses a different panel. There are also variants of the 55, 65, and 75 inch models with the model code X80CJ. That version appears to be the Costco and Sam's Club model, which should perform the same, except it comes with Sony's new Bravia CORE streaming service, which can stream movies at up to 80 Mbps, according to Sony. In Europe, you'll see the X80J sold alongside the X81J, but as far as we know, the two have the same specs. In Italy, it's called the X80JP.
| Size | US Model | Panel Type |
|---|---|---|
| 43" | KD-43X80J | ADS (IPS Family) |
| 50" | KD-50X80J | VA |
| 55" | KD-55X80J | ADS (IPS Family) |
| 65" | KD-65X80J | ADS (IPS Family) |
| 75" | KD-75X80J | Unknown |
If you come across a Sony X80J with a different panel type or that doesn't correspond to our review, let us know in the discussions, and we'll update the review. Some tests, like gray uniformity, can vary between individual units.
Our unit was manufactured in February 2021. You can see the label here.
Popular TV Comparisons
The Sony X80J is an okay entry-level TV, but it's a step down from 2020's Sony X800H. While it delivers fair picture quality and performance, it's on the pricier side, and there are better options out there for cheaper. Unlike some low-end TVs, it comes equipped with eARC and Dolby Vision support, although it can't fully take advantage of its HDR capability due to its limited brightness.

The Sony X80J and the Sony X85J use different panel technologies, each with strengths and weaknesses. The X85J is better for a dark room, as it has much better contrast and better black uniformity. The X80J is better for a wide seating area, as it has better viewing angles.
The Sony X80K/X80CK is the replacement for the Sony X80J, and both TVs are nearly identical, with only a few differences between them. The X80J is a bit better in a few areas like its improved color accuracy and faster response time, but the X80K also has less stutter. The X80K comes with the updated version of the Sony remote, but it has the same voice control features as the remote with the X80J anyway.
The Sony X90J is much better than the Sony X80J. The X90J uses a VA panel with a much better contrast ratio, and it has a full-array local dimming feature to improve black level, so it's better suited for watching movies or gaming in the dark than the X80J's IPS panel. The X90J also gets a lot brighter in both SDR and HDR. It has faster response times and a 120Hz refresh rate, and it has VRR support after a firmware update. If you often watch TV at an angle, the X80J might be a better choice because it has wider viewing angles.
The LG UP8000 and the Sony X80J are very similar IPS TVs. The only notable differences between them are that the X80J can display a wide color gamut for HDR, gets a bit brighter, and has better response times. It also has a flicker-free backlight, making it a good choice for people sensitive to backlight flicker.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests use specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.

The Sony X80J has a similar design to the 2020 Sony X800H. With thick bezels, it's not as sleek-looking as higher-end models, but it's a simple, no-nonsense design that you'd expect from an entry-level model.

The stand supports the TV okay, although there's still a bit of wobble. The cheaper materials stand out in the connection between the stand and the base of the TV, and there's no alternate stand position to allow for a taller soundbar to sit in front of the TV.
Footprint of the stand: 38.74" x 13.34"

The Sony X80J feels decently built. The TV is made entirely of plastic and is relatively lightweight, but it's not as sturdy as higher-end TVs. There's quite a bit of flex all around the backside as well as around the borders. Our unit appears to have a defect on the bottom left side of the screen; you can see two small white squares where the panel meets the border. However, we expect this is an issue with our unit only and doesn't affect scoring.

Unfortunately, the Sony X80J has mediocre contrast, so blacks look gray if you're in a dark room. There's no local dimming feature to improve contrast, either. You can expect this for all TVs that use IPS-family panels, but the 50" model, which uses a VA panel, has much better contrast.
The Sony X80J has decent brightness in SDR. It's not as bright as the Sony X800H, but it's bright enough to overcome glare in moderately-lit rooms, as long as there aren't a lot of windows. Brightness is fairly consistent across different scenes, but it gets a bit dimmer in the 2% window because of the TV's frame dimming.
These measurements were made after calibration, using the 'Custom' Picture Mode and the 'Expert 1' Color Temperature, with Brightness set to max.
If you want the brightest possible image without regard for picture quality, set the Picture Mode to 'Vivid', turn Contrast Enhancer off, and set Color Temperature to 'Neutral', with Brightness and Contrast set to max. This results in a slightly brighter image, with a peak luminance of 397 cd/m² with a 10% window.

The Sony X80J has sub-par HDR brightness. It's slightly brighter than in SDR but not bright enough to make highlights pop. The EOTF follows the target fairly well, though, which means that the overall brightness of scenes is pretty accurate overall. Dark scenes are over-brightened a bit, and bright scenes are limited by the low peak brightness. The EOTF rolls off sharply near the TV's peak brightness, which causes a loss of fine details in bright scenes. As with SDR, the frame dimming causes darker scenes with small highlights to be more dim overall.
These measurements were taken using the 'Cinema' Picture Mode with Brightness set to max and Color Temperature set to 'Expert 2'.
If you find HDR too dim, you can get a brighter image by setting the Brightness and Contrast to max, disabling Adv. Contrast Enhancer, setting Black Level to 'High', Gamma to max, and Color Temperature to 'Neutral'. These settings result in this EOTF, which is a lot brighter in dark scenes, but the overall peak brightness of the TV is the same.

In 'Game' mode, HDR brightness is nearly identical. There's no noticeable difference between the two picture modes.

The Sony X80J has good gray uniformity overall. The corners of the screen are a bit darker than the center of the TV, but this isn't very noticeable with real content. There's very little dirty screen effect throughout the center, which is great for watching sports. In near-dark scenes, the uniformity is even better, with no noticeable issues at all.
for pictures & test results
Unfortunately, the Sony X80J has disappointing black uniformity. The screen is cloudy throughout, and it appears blue due to the low contrast ratio. Sadly, there's no local dimming feature to improve black uniformity.

As expected for a TV with an IPS-family panel, the Sony X80J has very good viewing angles. The image stays accurate as you move off-center, making it a good choice for wider seating arrangements. Note that the 50 inch uses a VA panel, resulting in much worse viewing angles, so that size isn't for a wide seating arrangement.

The Sony X80J has decent reflection handling. It does a great job of diffusing ambient light, but it's not a good idea to place it opposite a window or bright lamp since it struggles with direct light.

The Sony X80J has amazing out-of-the-box color accuracy. There are very few noticeable inaccuracies with colors and white balance, and while gamma is a bit off-target, making scenes appear darker than they should, it's not very far off. It's normal for Sony TVs, which usually target a higher average gamma than other manufacturers. The color temperature is quite close to the 6,500K target, but it's a touch on the warmer side, so there's a slight reddish tint to everything.

The Sony X80J has mediocre color volume. It can't fill out the full range of greens, and due to the low contrast ratio, it can't display dark saturated colors very well. The colors it can display are just as bright as pure white, which is great.
for pictures & test results
Gradients look amazing on this TV. There's some banding in the darker grays, greens, and reds, but overall it's not very noticeable with real content. Unlike higher-end Sony TVs, there are no gradient smoothing features to reduce banding in some content.

There are almost no signs of temporary image retention, except immediately after displaying a high-contrast static image for 10 minutes. Even so, it disappears quickly.
Although some IPS and similar panels can suffer from temporary image retention, this doesn't appear to be permanent as seen in our long-term test.

The Sony X80J has a great response time. It's slightly improved over the Sony X800H, although like that TV, there's a bit of overshoot in the 0-20% transition, which can show up as smearing in darker scenes. However, it's not as bad as TVs with VA panels.
for pictures & test results
Unlike many TVs, the Sony X80J has a flicker-free backlight, which is great if you're sensitive to flicker. It does flicker at a very high frequency with the backlight set to '0', but this isn't noticeable.

The Sony X80J has an optional backlight strobing feature, commonly known as black frame insertion (BFI). However, the minimum frequency at which it can strobe or flicker its backlight is 120Hz, which causes duplications in motion when watching 60fps content. To enable BFI, set Motionflow to 'Custom' and adjust the Clearness slider to max. Note that the BFI score only takes into account which frequencies the TV can flicker at, not how well the BFI performs.
for pictures & test results
The TV can interpolate lower frame rate content up to 30fps. It works fine for the most part but introduces motion artifacts in busier scenes. To enable motion interpolation, set Cinemotion to 'High' and Motionflow to 'Custom', with the Smoothness slider to max.
Because of the TV's fast response time, there may be some stutter when watching low frame rate content, like movies, since each frame is held on longer. Motion interpolation can help reduce stutter if it bothers you.
This TV removes 24p judder automatically from 24Hz sources, like a Blu-ray player or a streaming stick with a "match frame rate" setting. Unfortunately, it can't remove judder completely from 60p/60i sources, like cable boxes, or native apps, although setting Cinemotion to 'High' and Smoothness to max in the Motionflow menu can make judder less apparent.
This TV doesn't support any advanced gaming features, like FreeSync or G-SYNC variable refresh rates, and it's limited to a 60Hz refresh rate. If you prefer something with a higher refresh rate and VRR support, consider the Samsung Q80B QLED.
The TV has a remarkably low input lag, resulting in a very responsive gaming experience. Like most TVs on the market, it has to be in the dedicated 'Game' mode for this to work. Outside 'Game' mode, or with motion interpolation enabled, the input lag is extremely high, and even casual gamers are likely to notice it.
The Sony X80J supports most common resolutions at 60Hz. It can display chroma 4:4:4 properly in all supported resolutions, except for 1440p @ 60Hz, though, which is important for text clarity from a PC. To do so, the TV must be in either 'Game' or 'Graphics' Picture Mode, with 'Enhanced Format' enabled for the HDMI input you're using. 'Enhanced Format' needs to be enabled for full HDMI bandwidth signals.

The Sony X80J has a max refresh rate of 60Hz and lacks HDMI 2.1 bandwidth, so the highest advanced console resolution it supports is 4k @ 60Hz with HDR.
Although the Sony X80J doesn't support HDMI 2.1 bandwidth, it still has an eARC port. This allows you to send high-quality audio formats from sources connected to your TV through to your soundbar or home theater system.
