If you're looking to save a little and primarily watch content in brighter rooms, the Amazon 4-Series could suit you as it performs fairly well there. However, for a general increase in picture and build quality, including better performance for gaming and watching sports, the slightly pricier Samsung CU7000 might be the better choice. The Samsung also supports a wider range of high dynamic range (HDR) formats, which enhances picture quality for compatible content, and has better accessibility features like voice commands. Neither TV is particularly strong in dark room performance or sound, with basic speakers, so it may be worth investing in a soundbar for either model. 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."
