In Europe, you'll see the X80J sold alongside the X81J, but as far as we know, the two have the same specs. 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. There are also variants of the 55, 65, and 75 inch models with the model code X80CJ. For the most part, we expect our results to be valid for those sizes, except for the 50 inch, which uses a different panel. We tested the 55 inch Sony X80J (KD-55X80J), which is also available in 43, 50, 65, and 75 inch sizes. The new interface is fast, easy-to-use, and has a huge selection of streaming apps. Like other 2021 Sony TVs, it comes with Google TV, which replaces Android TV. 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.

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. That said, it has good wide viewing angles, and it gets decently bright, meaning glare won't be an issue in moderately-lit rooms. 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. It lacks many features you'd find on higher-end TVs but performs as expected for a lower-tier IPS-type model. The Sony X80J is an entry-level 4k TV from Sony's 2021 lineup.
