The TCL QM8 offers higher picture quality, better gaming performance, and a brighter screen, making it suitable for bright rooms and immersive movie experiences. However, it's typically much more expensive than the TCL S555. On the other hand, the TCL S555 comes at a lower price and still delivers decent performance for movies and casual gaming but isn't as bright, which can be a downside in well-lit environments. Its picture quality and gaming capabilities are not as advanced as the TCL QM8. If budget is a concern and your viewing environment is typically not very bright, the S555 could be sufficient. Otherwise, for higher performance in gaming and bright room conditions, the QM8 would be a better choice. Give Feedback

The TCL QM8 (LCD) is best in class for bright room, while the TCL S555 (LCD) is good.
The TCL QM8 performs best in a bright room due to its higher SDR and HDR brightness, along with better handling of reflections, making it more suited for environments with lots of light; whereas the TCL S555, though with good performance, is not as bright and has lower capability in minimizing reflections, but it does offer slightly better contrast, color volume, and color gamut which can be beneficial for color richness and depth in less demanding lighting conditions.

Although they have very similar scores, PerfectRec considers TCL QM8 (LCD) to be very good for movies & TV, while the TCL S555 (LCD) is good.
The TCL QM8 stands out for watching movies and cinematic TV due to its excellent local dimming, high contrast, and superior black uniformity, which are crucial for deep blacks and rich picture detail in dark scenes. On the other hand, the TCL S555, while offering good movie-watching capabilities with better color accuracy out of the box, falls short with lower local dimming performance and black uniformity, impacting its ability to deliver the same level of depth and detail in dark sections of an image.

The TCL QM8 (LCD) and TCL S555 (LCD) are both only fair for sports.
The TCL QM8 has very good response time and deals with reflections better, making it suitable for sports in rooms with some light; however, its viewing angles are limited, which can affect the experience in a wide seating arrangement. In contrast, the TCL S555 also has a good response time for watching sports but struggles with reflections, which means it might not be the best choice in well-lit environments, yet it offers slightly better viewing angles.

"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 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.
