The Hisense U7K offers a slightly better movie and gaming experience, with high picture quality and smooth motion handling, making it ideal for dimmer rooms and immersive viewing. The TCL R646, while also good for movies, excels more in bright-room viewing, thanks to its superior reflection handling, which can be preferable if you plan to watch TV in a well-lit room. Both TVs support gaming features, but the Hisense U7K has a higher refresh rate, which may appeal to gamers looking for the most fluid visuals. Considering the similar price point, your preference for room brightness and gaming may guide your decision between the two. Give Feedback

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.
