The TCL S555 offers better performance across most content, making it a good choice if you prioritize image quality, particularly in dark and bright rooms, and for watching movies. It is more expensive than the TCL S446. If your budget is limited, the S446 still provides decent overall performance but might not deliver as rich a viewing experience in darker settings. Also, for gamers, the difference is smaller, so the S446 may suffice if gaming is your primary use. Neither TV is well-suited to very bright rooms, but the S555 has a slight edge. Consider how the room lighting conditions will affect your viewing experience. Give Feedback

The TCL S555 (LCD) is good for movies & TV, while the TCL S446 (LCD) is poor.
The TCL S446 lacks local dimming and has poor black uniformity, reducing the depth and quality of black scenes, which is vital for movies and cinematic content, and although its colors out of the box are excellent, its lower contrast impacts the overall picture richness. On the other hand, the TCL S555 boasts much better contrast, effective local dimming, and strong black uniformity, ensuring deeper blacks and vivid picture quality, which enhances the movie-watching experience despite having a poorer viewing angle.

The TCL S555 (LCD) is only fair for gaming, while the TCL S446 (LCD) is poor.
The TCL S446 has fair response time but very good input lag, making it suitable for casual gaming, although there might be some delay in fast-moving scenes. In contrast, the TCL S555, while not specified, presumably offers better performance for gaming due to its fair classification, suggesting it has a faster response time and lower input lag, reducing ghosting and delay for a smoother gaming experience.

The TCL S555 (LCD) is very good for cartoons & animation, while the TCL S446 (LCD) is only fair.
The TCL S555 provides a very good experience for watching cartoons and animation because it has excellent out-of-the-box colors and a good color gamut, which ensures vibrant and accurate hues. In contrast, while the TCL S446 also offers excellent out-of-the-box colors, its color gamut is poor, meaning that it might not display as wide a range of colors as the S555, thus making it fair for the same content.

The TCL S555 (LCD) is good for news, talk, & other TV, while the TCL S446 (LCD) is only fair.
The TCL S446, while offering excellent upscaling of lower-resolution content and colors that are vibrant straight out of the box, falls short in SDR brightness which is just fair, making it less suitable for bright rooms. On the other hand, the TCL S555 with its very good SDR brightness and a richer color gamut will provide a more vivid viewing experience, especially in well-lit environments, but has a lower upscaling score which means it may not handle lower-resolution content as smoothly.

The TCL S555 (LCD) is good for bright room, while the TCL S446 (LCD) is poor.
The TCL S555 is suited for bright rooms because it has much higher SDR and HDR brightness levels and better handling of reflections compared to the TCL S446, which exhibits lower brightness and is less effective at reducing reflections, thus performing poorly in well-lit environments. Additionally, the S555's superior contrast, color volume, and color gamut contribute to a more vibrant picture in various lighting conditions, whereas the S446, while acceptable, does not excel in these areas.

The TCL S446 (LCD) and TCL S555 (LCD) are both only fair for sports.
The TCL S446 has good handling of reflections and wider viewing angles, making it a better option in brighter rooms or for group watching, but its response time and motion processing are fair, which can result in some motion blur during fast sports scenes. The TCL S555, while having poorer reflection handling and viewing angles that limit its optimal use to darker environments and more direct viewing positions, also offers only fair motion processing, meaning while its contrast is better for darker rooms, both may exhibit motion blur in sports.

"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.
