The Samsung QN90B (LCD) is very good for movies & TV, while the Samsung Q80C (LCD) is only fair.
The Samsung QN90B outperforms the Samsung Q80C for movies and cinematic TV primarily because its superior contrast, local dimming, and black uniformity enhance the depth and detail in dark scenes. The Q80C, while offering commendable performance, may not deliver the same level of richness in dark visuals, and despite its good color and viewing angle attributes, the QN90B holds a distinct advantage in the key areas that matter most for cinematic content.

"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."
