If you are on a tight budget and want to save a bit, the Amazon 4-Series may be the more economical choice, but keep in mind that it has poor performance across most viewing categories including picture quality, gaming, and viewing in both dark and bright rooms. On the other hand, the Hisense U6H is slightly more expensive but offers good overall picture quality, fair gaming performance, and good performance in both dark and bright rooms, making it a better choice for a variety of viewing experiences. The Hisense U6H also has better support for high dynamic range (HDR) formats, which enhances the viewing experience for compatible content. If sound is a concern, the Hisense U6H also has a more powerful speaker setup. Therefore, if you can stretch your budget a bit, the Hisense U6H is the better investment for a higher quality viewing experience across different types of content. Give Feedback

Tech Advisor

Jim Martin | May 2023
"The attraction here is that the 4-Series uses Amazon’s Fire TV interface. Picture quality is good but unexceptional. At the discounted prices, which can seemingly be had regularly, they are better value."

Tom's guide

Matthew Murray | March 2023
"A budget TV that exceeds expectations. (...) For a TV that costs as little as this one does, its brightness and color are above-average (...) The U6H may not get quite as bright as its splashier siblings, but for its class, it fares pretty well. (...) As far as input lag, the U6H is an impressive performer. (...) Costing less than most of its direct competitors, and matching or bettering them in several key areas, it’s an irresistible value proposition. (...)"

About Amazon

Amazon, the largest online retailer in North America, has forged partnerships with TCL and Hisense to produce white-label TVs incorporating their Fire OS software. These Amazon-branded TVs typically compete in the low-end and mid-range segments, offering compelling price points. Leveraging their strong reputation, Amazon has swiftly built brand trust in the TV market despite being relatively new to it. To enhance their popularity, these TVs integrate features from the Amazon ecosystem, including Alexa, providing users with a seamless and interconnected TV experience.

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.
