The Samsung QN90B offers a significantly better overall picture quality, which is more pronounced in bright rooms, and it boasts superior contrast and color quality out of the box. If you're a movie enthusiast or enjoy gaming, the Samsung QN90B delivers better performance in these areas. However, it comes at a premium price compared to the LG NANO90. The LG NANO90 is less expensive and still provides good gaming experiences, but its picture quality, particularly in dark and bright rooms, isn't as strong as the Samsung QN90B. If budget is a major consideration and you're looking for an affordable option that still offers good gaming performance, the LG NANO90 may suit your needs. Give Feedback

The Samsung QN90B (LCD) is very good for movies & TV, while the LG NANO90 (LCD) is poor.
The LG NANO90's lower contrast, weaker local dimming, and poorer black uniformity make it less suitable for movies and cinematic TV, resulting in compromised dark scene depiction and less impressive picture depth.

In comparison, while the LG NANO90 is a fair option with good SDR and HDR brightness, and very good reflection handling, it doesn't match the Samsung QN90B's performance in these key aspects critical for bright room viewing.

"Here we have HDR pictures that look bright, but also manage to typically hit decently deep black levels.WebOS continues, though, to be one of the easiest to use. Connections are strong for a mid-range TV. Native 4K pictures look crisp and detailed."

"The QN90B delivers one of the brightest pictures we’ve ever seen, showcasing HDR content better than just about every LCD/LED TV on the market. If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress. All four of the QN90B’s HDMI 2.1 ports support 4K gaming at 120fps a centerpiece feature of the Xbox Series X and PlayStation 5."
