If budget is your main concern, the Amazon 4-Series (LCD) offers a large screen at a budget price, making it accessible for casual viewing in a variety of content, though its performance is on the lower end across the board. In contrast, the LG G1 (OLED) is at a premium price, providing outstanding picture quality, excellent gaming experience, and superb performance for movies and sports, especially in dark rooms. The OLED technology also means better viewing angles and superior color and contrast. Being more expensive, the LG G1 includes high-end features like 4k at 120Hz, HDR support, and better sound with built-in Dolby Atmos. However, the Amazon model may still be suitable if your viewing environment is brighter, as its performance is better in such conditions compared to how it does in the dark, and if your content consumption doesn't demand the highest quality visuals and features.

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."
