If you're on a tight budget and primarily watch content in dimmer environments, the Amazon 4-Series might be suitable despite its poorer performance in most viewing conditions. For a generally better visual experience, particularly for sports and in bright rooms, the Sony X80K is a step up, offering good sports content performance and fair bright room visibility, but at a higher cost. Gamers and those desiring richer colors should note that both TVs are less ideal, as they have poor gaming scores and color reproduction. Neither TV is optimal for dark rooms, but the Sony X80K's good gray uniformity and fair HDR brightness score give it an edge for HDR content viewing. Keep in mind that HDR will not be at its best on either model, and sound quality is only fair, so an external sound system might be beneficial. If using a TV as a monitor is important, the Sony X80K supports it with fair performance, whereas the Amazon 4-Series is not recommended for monitor use. 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."

"The Sony Bravia X80K is an inexpensive LCD TV that turns out pleasing visuals and is armed with a number of other desirable features. Sony’s robust internal processing, results in generally better picture quality than you’ll usually get for this price. In practice, the X80K is satisfying to watch. You’re not going to get as sumptuous a picture as you may with other TVs from Sony or other companies, but we didn’t encounter anything that looked bad on it."
