The TCL S455 is budget-friendly and notably less expensive than the S555. If cost is a high priority and you mainly watch in darker settings, it's worth considering. However, it doesn't perform as well in bright rooms and its overall picture quality is moderate. The S555 is more expensive but offers a significant bump in overall picture quality and is better suited for bright environments. It excels at movie watching and supports advanced HDR formats like Dolby Vision and HDR10+, which the S455 does not. If you're a gamer, you'll appreciate the S555's better response times and gaming performance. Give Feedback

The TCL S555 (LCD) is good for movies & TV, while the TCL S455 (LCD) is only fair.
The TCL S555 offers a superior cinematic experience mainly due to its higher contrast, more effective local dimming feature, and better black uniformity compared to the TCL S455, all of which contribute to deeper blacks and more detailed shadows in movies. Additionally, the S555 displays more vibrant, accurate colors straight out of the box, enhanced color volume, and improved gray uniformity, which translates to a richer and more consistent picture, albeit with similar limitations in viewing angles as the S455.

The TCL S555 (LCD) is only fair for gaming, while the TCL S455 (LCD) is poor.
The TCL S455 is considered poor for gaming due to having just a fair response time and input lag, which means it's slower to react to input and refreshes the image less smoothly compared to TVs with better performance. The TCL S555, while still fair in these aspects, may offer slightly better gaming experiences as its response time and input lag are rated higher within the same fair category.

The TCL S555 (LCD) is very good for cartoons & animation, while the TCL S455 (LCD) is only fair.
The TCL S555 provides a 'very good' experience when watching cartoons and animation due to its better color reproduction straight out of the box and a wider color gamut compared to the TCL S455, which only offers a 'fair' performance in these areas. The S555's enhanced colors make vibrant animated content more lively and truer to the creator's intent, while the S455, although more affordable, may appear less vivid.

The TCL S555 (LCD) is good for news, talk, & other TV, while the TCL S455 (LCD) is only fair.
The TCL S555 is better for watching news, talk shows, and TV programs because it has superior upscaling and significantly higher SDR brightness compared to the TCL S455, which results in clearer images and better performance in bright rooms. Additionally, the TCL S555's improved contrast and color out of the box contribute to a more vibrant and accurate picture.

The TCL S555 (LCD) is good for bright room, while the TCL S455 (LCD) is only fair.
The TCL S555 is better suited for bright rooms than the TCL S455 because it has higher SDR and HDR brightness, which makes the screen more visible in well-lit conditions. Additionally, even though both models struggle with reflections, the S555 manages them slightly better, enhancing viewability in bright environments. Contrast, color volume, and color gamut are less critical but still important, and both TVs perform similarly in these areas.

The TCL S555 (LCD) and TCL S455 (LCD) are both only fair for sports.
The TCL S455's fair performance in sports viewing is limited by its modest response time and reflections handling, which can affect fast-moving scenes and viewing in well-lit rooms. Similarly, the TCL S555 shares comparable weaknesses in motion processing and is also hampered by its poor reflection handling, although it slightly betters the S455 with its response time and a better viewing angle, which might offer a more consistent picture when seen from the side.

"A highly affordable but reliably kitted-out 4K Roku TV that, while far from perfect, still punches above its price and delivers a great user experience. If you want to soup up movie night for a bargain, the 4-Series won’t let you down. You may never need to plug in a set-top box or streaming device."

"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.
