When considering the Samsung QN90B compared to the TCL S450G, the Samsung is a premium-priced option with noticeably better overall picture quality, higher brightness levels for both standard and high dynamic range content, and superior reflection handling, which makes it a better choice for well-lit rooms. It also excels in gaming performance, with lower input lag and a faster response time, providing a smoother experience for fast-paced gameplay. Additionally, the Samsung offers better contrast, black uniformity, and out-of-the-box colors, enhancing the viewing experience for movies and series. The TCL S450G, on the other hand, is a budget-priced TV that offers less performance in most areas, including picture quality, brightness, and gaming features. However, for those who prioritize affordability over top-tier performance, it represents a significant cost saving while still providing a satisfactory viewing experience for various types of content like news, talk shows, reality TV, and animation. Both TVs support popular HDR formats like HDR10 and HLG, but the Samsung also supports HDR10+, which can improve HDR performance for compatible content. In summary, if you are willing to invest more for a superior viewing experience, particularly in brightness and gaming, the Samsung QN90B is the better choice. If you are looking for a more affordable option and are willing to compromise on some performance aspects, the TCL S450G could meet your needs. 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.
