The TCL QM8 is an upper midrange priced TV with better overall picture quality, making it more suitable for gaming and movie enthusiasts who are looking for high performance and can afford to spend more. It is also equipped with MiniLED technology and is better suited for bright rooms. In contrast, the TCL S455 offers a budget-friendly option and still provides satisfactory performance for general TV viewing, but won't excel in gaming or in bright areas as much as the QM8. If your budget is limited and your viewing habits are casual, the S455 might be the wiser economical choice. Give Feedback

Lee Neikirk | January 2022
"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.
