The LG QNED90 is generally less expensive. If you're looking for a TV mainly for gaming or watching news, talk shows, and reality TV, the LG QNED90 would be a satisfactory choice. However, if you often watch movies and series in both bright and dark rooms, the Samsung QN90A will give you better picture quality. The Samsung QN90A also holds an advantage in sports viewing and is slightly better for using as a monitor. If you're ready to spend more for these improvements, the Samsung might suit you better.

The Samsung QN90A (LCD) is very good for movies & TV, while the LG QNED90 (LCD) is only fair.
The Samsung QN90A delivers a better movie and cinematic TV experience than the LG QNED90 largely because it has superior contrast, local dimming, and black uniformity, which are very important for deep blacks and detailed dark scenes. While the LG QNED90 has good qualities, its lower performance in these key areas, along with less impressive colors out of the box and color volume, makes it less suitable for viewers who prioritize a richer viewing experience.

Although they have very similar scores, PerfectRec considers Samsung QN90A (LCD) to be good for sports, while the LG QNED90 (LCD) is only fair.
The Samsung QN90A outperforms the LG QNED90 in sports watching thanks to its better motion processing and response time, ensuring smoother action with less blur during fast movements, and its superior handling of reflections, making it easier to watch in well-lit rooms. In contrast, the LG QNED90, while still good, has a slight edge over the Samsung in terms of viewing angles, which could be favorable in a setup where viewers are spread out across a wide area.
