If you're on a tight budget and mainly watch movies or play games in a dark room, the TCL S450R would save you money while offering fair picture quality and excellent black uniformity. However, if improved picture quality, especially in brighter rooms, and better gaming features like a higher refresh rate are priorities for you, and you don't mind spending more, the TCL Q7 would be worth the extra cost. The Q7 also has a higher SDR brightness, making it more suited for well-lit rooms. For a more immersive sports watching or gaming experience with clearer motion and crisper upscaling, the Q7 is the better option. Keep in mind though, the Q7 does not excel in upscaling lower resolution content and wider viewing angles. If you often watch content with large groups spread out across the room, the S450R might be more fitting despite its limitations. Give Feedback

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.
