If you're looking for a very budget-friendly option, the Amazon 4-Series may suit you, but it has limitations when it comes to picture quality and is not recommended for a bright room or for high-quality movie or gaming experiences. The Vizio V-Series '22, while generally more expensive, offers slightly better performance for watching sports and cartoons, and has support for more HDR formats like Dolby Vision and HDR10+, which could enhance viewing experience for compatible content. Both TVs have their strengths, but if you prefer better color quality out of the box and additional HDR format support, the Vizio may be worth the extra cost. If budget is your primary concern and you have low expectations regarding picture quality, the Amazon 4-Series could be sufficient. 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 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.
