If you're on a tight budget and want a TV that is somewhat less expensive, the Amazon 4-Series could serve as a basic option for general use. However, it has poor picture quality in various contents and environments, and you might find its performance unsatisfactory in bright rooms or for gaming. On the other hand, the Hisense U6G, while somewhat more expensive, offers better overall picture quality, particularly in both dark and bright rooms, making it versatile for different viewing conditions. It has very good scores in movies, series, cartoons, and animation, and its performance with sports content is fair, which could improve your viewing experience significantly. Additionally, features like HDR support, including HDR10+ and Dolby Vision, improve the video quality for compatible content. If picture quality, especially in diverse lighting conditions, and a richer feature set are important to you, the Hisense U6G would be a better choice despite the higher cost. 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."

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.
