The Amazon 4-Series is a budget-friendly option and offers a decent experience for general use, including watching news, talk shows, and reality TV. However, it's not the best choice for dark room viewing due to its lower performance in those settings. On the other hand, the LG QNED90 is more expensive but provides superior overall picture quality with better performance for watching sports, gaming, and movies. It also offers better brightness for viewing in well-lit rooms. If these features are important to you and you're willing to spend more, the LG QNED90 could be the better choice. Give Feedback

The LG QNED90 (LCD) is only fair for movies & TV, while the Amazon 4-Series (LCD) is poor.
The Amazon 4-Series (LCD) is considered poor for watching movies and cinematic TV largely because it lacks a local dimming feature, which is essential for deeper blacks and contrast, and it exhibits inadequate black uniformity, resulting in less immersive dark scenes. The LG QNED90 (LCD), although rated only fair, offers local dimming and better black uniformity, which enhances its contrast and visual performance in dark movie scenes, but it still has limitations in displaying a wide color volume and consistent colors out of the box.

The LG QNED90 (LCD) is very good for gaming, while the Amazon 4-Series (LCD) is poor.
The Amazon 4-Series lags behind in gaming due to a poor response time, which affects how quickly the image updates and can lead to blurred motion in fast-paced games, while its refresh rate is limited to 60Hz, reducing the smoothness of gameplay compared to higher rates. In contrast, the LG QNED90 is superior for gaming with a good response time ensuring crisp motion and supporting a 120Hz refresh rate, providing a more fluid gaming experience with less motion blur and more responsive input.

The LG QNED90 (LCD) is good for cartoons & animation, while the Amazon 4-Series (LCD) is poor.
The LG QNED90 (LCD) displays cartoons and animation better than the Amazon 4-Series (LCD) largely because it offers good colors straight out of the box, and both its color gamut and color volume are rated good, which ensures a wide and accurate representation of colors. On the other hand, the Amazon 4-Series has poor scores in these areas, resulting in less vibrant and accurate colors for animated content.

The LG QNED90 (LCD) is very good for news, talk, & other TV, while the Amazon 4-Series (LCD) is poor.
The Amazon 4-Series struggles with watching news, talk shows, and other TV programs, primarily because of its fair upscaling and SDR brightness, which could lead to a less clear picture and dimmer display in brighter rooms. In contrast, the LG QNED90 excels in these areas with very good SDR brightness and upscaling, resulting in sharper images and better visibility even in well-lit environments.

"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."

"When it comes to HDR brightness it has very bright highlights and impressive HDR. In terms of design the QNED90 looks beautiful. The TV did great with fast response times, excellent reactions and instant rendering of all our commands. If you look for a good performing premium 4K TV the QNED90 ticks all the boxes."
