If you're looking for a TV with better overall picture quality, the Sony X90J is a superior choice. It performs significantly better in dark rooms and comes with a good full-array local dimming feature which contributes to its superior contrast. It also has higher brightness capabilities, which can make a noticeable difference when watching movies or gaming in bright and dark environments. However, the Sony X80K offers a good value with a lower price point. It has decent performance in sports content and bright room viewing but falls short in dark room performance compared to the X90J. The X80K might be more suitable if budget is a key concern and your viewing conditions are generally well-lit or if most content watched isn't heavily reliant on dark scene performance. For gaming, the X90J provides a better experience with faster response time and better motion processing, making it better suited for action-packed games or those sensitive to input lag. Both TVs support similar HDR formats like Dolby Vision and HLG, but if high-quality sound from the TV speakers is important to you, neither of these options stand out as both have standard speaker setups. Overall, if you are willing to invest more for enhanced picture quality and gaming experience, the X90J is the favorable option. If you prefer to save money and require a TV that offers decent performance in bright rooms and for watching sports, then the X80K might suffice. Give Feedback

The Sony X90J (LCD) is good for movies & TV, while the Sony X80K (LCD) is poor.
The Sony X90J has a higher contrast and better local dimming feature which makes it good for movies and cinematic TV, providing deep blacks and pronounced highlights, while the Sony X80K displays weaker blacks due to its lower contrast ratio and lack of local dimming, leading to a less immersive experience for the same content. Additionally, the X90J has better black uniformity which enhances dark scenes, a crucial aspect for watching movies and cinematic TV, compared to the X80K which falls short in this area.

The Sony X90J (LCD) is very good for gaming, while the Sony X80K (LCD) is poor.
The Sony X80K's gaming performance is limited by its fair response time and very good input lag, which may lead to less fluid motion and slightly delayed reactions in fast-paced games. Conversely, the Sony X90J delivers a better experience for gamers with its very good response time and good input lag, ensuring smoother transitions and more responsive gameplay.

The Sony X90J (LCD) is very good for cartoons & animation, while the Sony X80K (LCD) is good.
The Sony X80K performs well with colors straight out of the box, which contributes to its effectiveness for cartoons and animation, but has a more limited color volume compared to the Sony X90J. The Sony X90J, on the other hand, offers excellent color reproduction out of the box and boasts a broader color gamut and color volume, providing a richer and more vibrant display for animated content.

The Sony X90J provides a better viewing experience in a bright room compared to the Sony X80K, primarily because it offers higher SDR and HDR brightness levels, allowing it to combat glare more effectively. Additionally, while both TVs struggle with reflections to some degree, the X90J's local dimming feature, better color volume, and wider color gamut enhance its ability to maintain picture quality in well-lit environments.

The Sony X80K (LCD) and Sony X90J (LCD) are both good for sports.
The Sony X80K offers wider viewing angles which may be beneficial for group watching during sports events, but its response time is only fair leading to some motion blur in fast-paced scenes. The Sony X90J, in contrast, has a very good response time minimizing motion blur, making it more suitable for fast-paced sports action, but poorer viewing angles mean the picture quality may deteriorate when viewed from the side. Both models handle reflections only fairly, so glare in bright rooms could be a concern when watching during the day.

Tom's guide
Matthew Murray | February 2023
"The Sony Bravia X80K is an inexpensive LCD TV that turns out pleasing visuals and is armed with a number of other desirable features. Sony’s robust internal processing, results in generally better picture quality than you’ll usually get for this price. In practice, the X80K is satisfying to watch. You’re not going to get as sumptuous a picture as you may with other TVs from Sony or other companies, but we didn’t encounter anything that looked bad on it."
