Our Verdict
LG C3 OLED
Samsung QN900C 8k QLED
The LG C3 OLED and the Samsung QN900C 8k QLED are better for different uses. The LG is better in a dark room due to its nearly infinite contrast ratio, better black uniformity, no blooming, and perfect zone transitions, so you get perfect blacks with no distractions. The LG also has better HDR gradient handling for less banding, and its wider viewing angle makes it a better choice for watching TV with other people, as no one will have to watch a washed-out image. The Samsung is better for a bright room due to its higher SDR peak brightness, so it overcomes glare better. The Samsung is also capable of 4k @ 144Hz, so it's a better option for a gaming PC capable of 144 fps.
