The Sony X77L offers good performance in sports content and wide viewing angles, making it suitable for games or gatherings where viewers are spread out across the room. However, its dark room performance is not as strong as the TCL S555. On the other hand, the TCL S555 excels with movies and series, as well as cartoons and animation, and has superior contrast and brightness, especially in dark rooms. It's also better suited for a bright room due to its higher bright room score. Both TVs are similarly priced and have similar overall picture quality, but the TCL has an edge in most content viewing scenarios, except for sports where the Sony might be preferred. Consider the types of content you watch most often to guide your choice. Give Feedback

The TCL S555 (LCD) is good for movies & TV, while the Sony X77L (LCD) is poor.
The TCL S555 displays a more immersive movie-watching experience with its higher contrast, superior black uniformity, and effective local dimming which enhances dark scene representation, however, it has a narrower viewing angle than the Sony X77L making it less ideal for wide seating arrangements. On the other hand, the Sony X77L, despite its poorer contrast and black levels which can diminish the depth of movie scenes, offers better color accuracy out of the box and wider viewing angles, benefiting environments where viewers are spread out around the room.

The Sony X77L (LCD) and TCL S555 (LCD) are both only fair for sports, though the Sony X77L (LCD) is somewhat better.
The Sony X77L and the TCL S555 both have their limitations when it comes to watching sports; the Sony struggles with response time and motion processing, which could lead to blur during fast action, while it handles reflections better than the TCL which is advantageous in bright rooms. Conversely, the TCL has a good response time which minimizes blur, but poor reflection handling could be distracting in well-lit environments; both have fair viewing angles which could affect the picture quality when viewed from the side.

The TCL S555 (LCD) is only fair for gaming, while the Sony X77L (LCD) is poor.
The Sony X77L has poor response time, which can lead to motion blur in fast-paced games, while the TCL S555's fair rating for response time indicates less motion blur. Additionally, the TCL S555 has the best input lag, which means it will respond more quickly to player actions than the Sony X77L, which has only a very good rating for input lag.

The TCL S555 (LCD) is very good for cartoons & animation, while the Sony X77L (LCD) is only fair.
The TCL S555 outshines the Sony X77L in terms of watching cartoons and animation because it boasts a better color gamut, which allows for a more extensive and accurate range of colors, enhancing the vibrant and varied hues typically found in animated content. Additionally, the TCL has superior color volume, contributing to its ability to display a wider spectrum of colors at different luminance levels, whereas the Sony, despite providing very good colors out of the box, falls behind with a poor color gamut and fair color volume, limiting the richness and depth of colors displayed on the screen.

The TCL S555 (LCD) is good for news, talk, & other TV, while the Sony X77L (LCD) is only fair.
The TCL S555 excels in displaying news and TV programs since it has excellent SDR brightness and contrast, ensuring on-screen content appears clear and well-defined in various lighting conditions. On the other hand, while the Sony X77L offers fair performance in these aspects, it may not match the TCL S555's level of clarity and depth in color representation for such content.

"For an entry-level model, Sony’s X77L is a decent 4K TV. It’s color reproduction, along with crisp and clean picture images revealed plenty of detail and clarity thanks in part to Sony’s excellent video processing."

"It looks great out of the box and the picture quality it is rock-solid for the price. (...) What really makes this a decent gaming TV, though, is the very low input lag. (...) But if you want to save a little money, the TCL S555 strikes a great balance between cost and performance – the kind of performance that’s impressive enough to deliver some wow to your eyes. (...)"

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.
