If you're on a budget and simply need a basic TV, the Amazon 4-Series might suffice, particularly if you'll use it in brighter rooms where its fair performance might be adequate. On the other hand, if you can spend a bit more, the Samsung AU8000 offers better performance for sports and general TV viewing, and it has better reflection handling which is beneficial in bright environments. It also has a slight edge in motion processing, color, and gaming response time. Neither TV is particularly suited for dark rooms or high-quality gaming experiences, but the Samsung may provide a more versatile and slightly improved viewing experience overall. 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."

Michael Desjardin | April 2023
"To put it directly: you’d never see a mid-range 4K TV hitting this black levels half a decade ago. AU8000 plays the part of a higher-end TV thanks to its sleek design. If you’re upgrading to a smart TV for the first time, the software is a great way to dip your toes in the streaming water."
