If you're on a tight budget, the Amazon 4-Series might appeal to you, but keep in mind it generally doesn't provide good picture quality for movies, sports, or gaming, and it isn't great in dark or bright rooms. In contrast, the Amazon Omni QLED offers better overall picture, particularly for movies and animation, and has good performance in a dark room. It is suitable for watching news, talk shows, and reality TV, and it supports HDR formats like HDR10+ and Dolby Vision, which the 4-Series does not. Although the Omni QLED is more costly, it's a better choice if you value picture quality and HDR content. Give Feedback

"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."

"This really is a TV designed for the streaming generation ... And it’s good to see support for both HDR10+ and Dolby Vision because it means more of the content you stream will be available in HDR. Overall, the Omni QLED is an impressive TV. It’s pretty bright, has good contrast and – thanks to those quantum dots – vibrant colours."
