If you're on a strict budget and mainly watch content in brighter rooms, the Amazon 4-Series might be suitable, though it has limited performance across most viewing conditions, and its picture and sound quality are not particularly strong. In contrast, if you're willing to invest in a higher-quality viewing experience for movies, sports, gaming, and general TV watching, the Hisense U8H offers superior picture quality, especially in dark rooms, and has robust gaming features. However, it won't perform as well in rooms with wide seating due to its limited viewing angles. Give Feedback

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."

Jaron Schneider | January 2023
"Hisense is over here making the best TVs for the majority of average families. U8H is a juiced-up utility knife of a television that manages to do a lot of things pretty well. The brightness this TV is capable of pushing out means I can see everything going on in any video game I’m playing regardless of what time of day it is"

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.
