Our Verdict
LG C2 OLED
Samsung QN90C/QN90CD QLED
The LG C2 OLED and the Samsung QN90C offer different strengths and weaknesses, so the best one depends mainly on your viewing conditions. The LG looks much better in a dark room thanks to its nearly infinite contrast ratio, resulting in perfect blacks with absolutely no blooming around bright highlights. The Samsung, on the other hand, is a much better choice if you're in a bright room or have a lot of windows, as it gets significantly brighter and can better overcome glare.
