The Hisense U7K is typically much more expensive, offering a significantly better picture quality and gaming experience than the TCL S455, which is more budget-friendly. The U7K will perform better in bright rooms and offers superior motion processing, color quality, and response time, making it a strong choice for movies and gaming. However, its dark room performance is not ideal for those environments. The TCL S455, while more affordable, won't perform as well overall, particularly in bright rooms and for gaming. It also lacks some advanced features like Dolby Vision and higher refresh rates found in the Hisense U7K. Give Feedback

The Hisense U7K is better suited for watching sports due to its very good response time and very good reflections handling, making fast-moving scenes clear and reducing glare from light sources.

"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 Hisense
Hisense, a Chinese TV manufacturer, entered the US market in approximately 2011 and has since acquired TV divisions from various companies such as Toshiba, Sharp, Hitachi, and NEC. Currently ranking as the fourth largest vendor in terms of sales volume, Hisense aims to capture a wide range of TV budget segments. They offer exceptional value with TVs that often outperform their competitors at similar price points, making them a compelling choice for consumers. In the US, they use Google TV as their smart TV software which provides the largest app selection and a very modern user interface, however it is not as user friendly as the software from other vendors.
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.
