If you're looking for a more budget-friendly option, the Amazon 4-Series is significantly less expensive and offers a reasonable performance for watching news, talk shows, and reality TV in bright rooms. However, it lacks in picture quality for movies in dark rooms and gaming experience is quite basic. On the other hand, the Vizio Quantum Pro, while costing more, provides a better overall viewing experience with higher performance for gaming, sports, movies, and series. It is also better suited for watching in both dark and bright rooms. In addition, it supports more advanced HDR formats which can enhance your viewing experience for compatible content. Give Feedback

The Vizio Quantum Pro (LCD) is only fair for movies & TV, while the Amazon 4-Series (LCD) is poor.
The Amazon 4-Series struggles with movies and cinematic TV due to its poor local dimming and black uniformity, which reduces contrast and detail in dark scenes, whereas the Vizio Quantum Pro, with its fair local dimming and better black uniformity, delivers improved contrast and detail. Furthermore, the Vizio's superior color volume enhances the viewing experience with richer, more vibrant colors, making it a better choice for cinematic content despite its higher price.

The Vizio Quantum Pro (LCD) is only fair for sports, while the Amazon 4-Series (LCD) is poor.
The Amazon 4-Series (LCD) has a poor response time which is crucial for watching fast-moving sports, and it also falls short in handling reflections, meaning it's not ideal for bright rooms. In contrast, the Vizio Quantum Pro (LCD) has a very good response time and handles reflections very well, improving the experience during sports but also making it a better fit for well-lit environments.

The Vizio Quantum Pro (LCD) is very good for gaming, while the Amazon 4-Series (LCD) is poor.
The Amazon 4-Series TV has a poor response time which can lead to motion blur during fast-paced games, while the Vizio Quantum Pro offers a very good response time, providing clearer motion. Additionally, the input lag, which is how quickly the TV responds to controller input, is very good on the Amazon 4-Series and good on the Vizio, but the superior response time on the Vizio makes it more suitable for gaming.

The Vizio Quantum Pro (LCD) is good for cartoons & animation, while the Amazon 4-Series (LCD) is poor.
The Amazon 4-Series is considered poor for watching cartoons & animation because it has poor colors out of the box and a poor color gamut, which are crucial for vibrant, varied hues. In contrast, the Vizio Quantum Pro is considered good for these types of content due to its fair colors out of the box and very good color gamut, thereby providing a richer, more accurate representation of the colorful and dynamic visuals typical in animation.

The Vizio Quantum Pro (LCD) is only fair for news, talk, & other TV, while the Amazon 4-Series (LCD) is poor.
The Amazon 4-Series struggles with upscaling and has only fair SDR brightness, limiting clarity and visibility, which is not ideal for regular TV programming such as news and talk shows. On the other hand, the Vizio Quantum Pro offers better SDR brightness, providing a clearer image in these scenarios, and its fair performance in upscaling is somewhat compensated by its very good colors out of the box and color gamut.

"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.
