If you are on a tight budget and primarily watch TV in bright rooms, the Amazon 4-Series may suit your needs despite its lower picture quality. On the other hand, the LG G2 excels in overall picture quality, especially for movies and in dark environments, but comes at a higher cost. The G2 also offers better gaming features and sound quality, making it ideal for a more immersive entertainment experience. However, the Amazon 4-Series can be a practical choice for casual viewing, especially where spending more is not an option. 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."

Stephen Withers | June 2022
"When it comes to picture quality alone, the LG G2 is absolutely among the best OLED TVs we've ever seen. You're getting a set that's basically impeccable across every aspect of its performance, it's truly one of the best TVs on the planet. The Brightness Booster Max technology really pays dividends to set it apart from the crown. The LG G2 is a superb OLED TV that delivers exceptional HDR performance with bright specular highlights, and incredibly accurate dynamic tone mapping."
