If you're on a tight budget and basic TV performance suffices, the TCL S450R is a cost-effective option, offering fair overall picture quality, sound, and gaming performance suitable for casual viewing in both bright and dark rooms. However, it struggles with local dimming and HDR brightness, which may affect the experience when watching high dynamic range content. On the other hand, the TCL QM8 is better suited for a premium viewing experience, boasting very good picture quality, exceptional SDR and HDR brightness, and excellent performance for movies and dark room viewing. It also possesses advanced gaming features, making it more suitable for intense gaming, but this comes at a midrange price point. The QM8 will struggle in rooms with wide seating due to its poor viewing angle, and despite having a high refresh rate, its motion handling is rated as poor. Choose the S450R if cost is a concern and your demands are modest; opt for the QM8 if you're willing to invest in higher quality for mixed use, including critical movie watching and gaming in varied lighting conditions.

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.
