If you are on a tight budget and primarily watch news, talk shows, or reality TV, the Vizio D-Series '22 might suit you well. However, if you can stretch your budget and value a better viewing experience for movies, cartoons, and animation, and don't mind sacrificing some performance in bright rooms and gaming, the Hisense U6K offers significant improvements in picture quality, contrast, and color. The Hisense U6K also has a higher number of HDMI ports, supports advanced HDR formats like Dolby Vision and HDR10+, and has better upscaling for high-resolution content, which can enhance your viewing experience, especially for newer content formats. Keep in mind, the viewing angle and reflections handling are not strengths for either TV, so they are best viewed straight-on in controlled lighting conditions. 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 Vizio

Vizio is an American company. While they initially gained recognition for offering budget-friendly TVs, they have successfully expanded their product lineup to include high-end options as well. They manufacture TVs primarily in Mexico, China, and Vietnam. Similar to many Korean TV brands, Vizio developed its own smart TV software called SmartCast. In the past, SmartCast was not the best smart TV software, but it has evolved so that it is now good for using your TV and connecting to streaming services.
