If you're looking for a TV that performs well in a bright room and offers better overall picture quality, especially for watching movies and sports, the TCL S555 is a suitable choice. However, it is more expensive compared to the TCL S450G. On the other hand, if you are on a budget and are looking for a generally inexpensive option, the TCL S450G could be appealing, but keep in mind that it won't perform as well in bright conditions and the picture quality won't be as good as the more costly TCL S555. Both TVs have a 65-inch screen and support for HDR content, although neither has standout speaker quality. Give Feedback

The TCL S555 (LCD) is good for movies & TV, while the TCL S450G (LCD) is poor.
The TCL S450G has a lower contrast and poor local dimming which leads to less impressive dark scenes and a less cinematic experience, whereas the TCL S555 features significantly better contrast, effective local dimming, and good black uniformity, enhancing movie and cinematic TV viewing with deeper blacks and better shadow detail. Additionally, the S555 offers more vibrant colors right out of the box and a better color volume, which contribute to a richer and more immersive viewing experience compared to the more washed-out appearance of the S450G.

The TCL S555 (LCD) is only fair for gaming, while the TCL S450G (LCD) is poor.
The TCL S450G has a poor response time, affecting motion clarity during gaming, while the TCL S555 shows good response time, ensuring smoother motion.

The TCL S555 (LCD) is very good for cartoons & animation, while the TCL S450G (LCD) is poor.
The TCL S450G is rated poorly for cartoons and animation viewing primarily due to underwhelming colors straight out of the box and a limited color gamut, which are crucial for vibrant and varied animations. In contrast, the TCL S555 performs very well, thanks to its excellent color rendition after initial setup and a wider color gamut that brings animated features to life with better range and depth of colors.

The TCL S555 (LCD) is good for news, talk, & other TV, while the TCL S450G (LCD) is poor.
The TCL S450G's SDR brightness is poor and its colors out of the box are just fair, leading to a less ideal experience for watching news and TV programs. In contrast, the TCL S555 has very good SDR brightness and very good colors out of the box, providing a clearer and more vibrant viewing experience for the same content.

The TCL S555 (LCD) is good for bright room, while the TCL S450G (LCD) is poor.
The TCL S450G struggles in bright rooms because it has poor SDR and HDR brightness and only a fair reflection handling, which makes it less suitable for environments with lots of light. On the other hand, the TCL S555 performs well in bright rooms due to its very good SDR brightness, good HDR brightness, and despite having poor reflection handling, its higher brightness levels compensate for glares.

The TCL S555 (LCD) and TCL S450G (LCD) are both only fair for sports.
The TCL S450G has a superior response time which is essential for watching fast-moving sports but struggles with reflections which can be distracting in well-lit rooms. Meanwhile, the TCL S555, while offering a good response time, has a wider viewing angle which is beneficial for group watching, but like the S450G, it doesn't handle reflections well, possibly affecting daytime sports viewing.

"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.
