The TCL R648 is a premium-priced TV with better overall performance, gaming experience, and bright room handling. It offers a higher-quality picture and sound and supports more advanced features like Dolby Vision and Atmos. Conversely, the TCL S455 is much less expensive and could be a good fit if you're on a budget. While suitable for casual viewing and some gaming, the S455 lacks the advanced features and picture quality of the R648, and it's not as good in brightly-lit rooms. Give Feedback

The TCL R648 (LCD) is good for movies & TV, while the TCL S455 (LCD) is only fair.
The TCL R648 is better for movies and cinematic TV due to higher contrast, better local dimming, and superior black uniformity, enriching dark scenes and maintaining detail. The TCL S455, while also having good contrast, is less capable in these aspects, leading to less defined shadows and details especially in darker content.

The TCL R648 (LCD) is very good for gaming, while the TCL S455 (LCD) is poor.
The TCL R648 is better for gaming as it has very good response time and good input lag, which means on-screen action is more fluid and commands from gaming inputs are registered quickly. Conversely, the TCL S455 has just fair response time and the best input lag score; however, the slower response time can result in more motion blur during fast-paced games, making it less ideal despite its excellent input lag.

The TCL R648 (LCD) is very good for cartoons & animation, while the TCL S455 (LCD) is only fair.
The TCL R648 outperforms the TCL S455 in displaying cartoons and animation due to its excellent colors out of the box and good color gamut and color volume, which means it provides more vibrant and varied colors. In contrast, the S455 has fair scores for colors out of the box, a poor color gamut and a fair color volume, resulting in less accurate and less saturated colors.

The TCL R648 (LCD) is good for news, talk, & other TV, while the TCL S455 (LCD) is only fair.
The TCL R648 offers excellent upscaling and very good SDR brightness, which enhances the clarity and visibility of standard content like news and talk shows, whereas the TCL S455, though fair in these aspects, may not render such content as brightly or as sharply, affecting overall viewing experience for regular TV programs. Additionally, the R648's superior local dimming and contrast contribute to a vivid and more engaging picture, compared to the S455, which may appear less dynamic and immersive due to its lower performance in these areas.

The TCL R648 (LCD) and TCL S455 (LCD) are both only fair for sports.
For watching sports, the TCL R648 offers better motion processing and a higher response time which translates to less motion blur, but reflections are only handled fairly and its viewing angles could be limiting if you have a wide seating arrangement. The TCL S455 also has fair handling of reflections and moderate viewing angles; however, its motion processing and response time are lower, which might not be ideal for fast-moving sports, but it compensates with excellent gray uniformity which helps in maintaining consistent picture quality across the screen.

"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."

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.
