If you're on a budget and want a large screen TV, the TCL S450R could be a satisfactory option for you. However, if you're willing to invest more for a higher quality picture, especially in bright rooms, the Samsung QN90B excels and also offers superior gaming performance and sound quality. The Samsung's reflection handling is excellent, making it a better choice if you watch TV in a room with lots of light. It also offers more advanced features such as a higher refresh rate and better HDR capabilities, which enhance the viewing experience for movies and gaming. On the other hand, the TCL model might be sufficient if your viewing habits include watching in a dark room and you're not looking for top-notch gaming or HDR performance. Give Feedback

Michael Desjardin | October 2022
"The QN90B delivers one of the brightest pictures we’ve ever seen, showcasing HDR content better than just about every LCD/LED TV on the market. If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress. All four of the QN90B’s HDMI 2.1 ports support 4K gaming at 120fps a centerpiece feature of the Xbox Series X and PlayStation 5."

About Samsung
Samsung, a South Korean electronics manufacturer, holds the title of being the largest global TV vendor in terms of units sold. They offer a diverse lineup of TV products that cater to various budget ranges. A notable achievement in recent years is the development of Quantum Dots, a technology that enhances color reproduction, resulting in richer and more vibrant hues. Samsung TVs are well-regarded for their high manufacturing quality and user-friendly software, making them an excellent choice for consumers seeking an intuitive viewing experience.
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.
