If budget is a primary concern, the Amazon 4-Series LCD is the more affordable option, however, its performance is lower across most viewing experiences. The Hisense U8G offers significantly better overall picture quality, with particular strengths in gaming, bright rooms, and for watching movies. It also has higher brightness capabilities and better color accuracy. The Hisense U8G may not offer the best viewing angles, so it's not ideal if you often watch TV from side angles. If you're a serious gamer or frequently watch in well-lit spaces and can invest more, the Hisense U8G would be a good choice. On the other hand, for casual viewing and if saving money is more important, the Amazon 4-Series suffices. 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.
