If you're looking for greater performance in brighter rooms and overall better picture quality, the TCL R646 could be a great choice. It also offers better gaming performance and higher contrast, making it suitable for movies in dark environments. However, this TV is typically a bit more expensive. Conversely, the Sony X80K is usually less expensive and offers better performance for watching sports. It also has good grayscale uniformity, which can be beneficial for general TV viewing. The Sony has wider viewing angles, so it's a good option if you often watch TV with a group spread out across the room. Give Feedback

The Sony X80K (LCD) is good for sports, while the TCL R646 (LCD) is only fair.
The Sony X80K is praised for its motion processing, which is vital for tracking fast movements in sports without much blur or ghosting, while the TCL R646 has lower motion processing performance, potentially resulting in less smooth movement during fast-paced games. Additionally, the Sony tends to handle reflections better, important for maintaining a clear picture in well-lit rooms, but the TCL offers better response time, which means it can render fast-moving objects slightly more sharply.

The TCL R646 (LCD) is very good for gaming, while the Sony X80K (LCD) is poor.
The TCL R646 offers a much better gaming experience due to its very good response time and good input lag at 120Hz refresh rates, making fast-moving images sharper and gameplay more responsive. In contrast, the Sony X80K's fair response time and good input lag at 60Hz will result in a less smooth gaming performance, with slower reactions to input from gaming controls and more blur during fast action.

The TCL R646 (LCD) is very good for bright room, while the Sony X80K (LCD) is only fair.
The TCL R646 is better suited for bright rooms due to its higher SDR and HDR brightness levels, which means it can maintain better visibility in well-lit conditions, whereas the Sony X80K offers only fair brightness, which could result in a less vibrant picture in bright rooms. Additionally, the TCL R646 has superior reflection handling, allowing it to reduce the impact of light reflections on the screen more effectively than the Sony X80K.

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."

About Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
