If you're on a tight budget and just need a basic TV, the Amazon 4-Series might serve your needs adequately despite its limitations in picture quality, especially in bright rooms and with gaming content. However, if you're willing to invest more for a significantly superior viewing experience with better brightness, color, and motion handling, particularly for watching movies, sports, or gaming in bright rooms, the Samsung QN90A offers a substantial upgrade across the board, including better sound quality and more advanced features like a higher refresh rate and support for a wider range of HDR formats.

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."
