Our Verdict
Samsung S90D OLED
LG B5 OLED
The Samsung S90D is better than the LG B5. Both TVs deliver a fantastic dark room viewing experience thanks to their nearly infinite contrast ratio, delivering deep inky blacks with no haloing around bright highlights. The Samsung model delivers a more impactful HDR experience, though, thanks to its higher HDR brightness and significantly better color volume. The Samsung TV has better reflection handling, making it better for a bright room, but there's a noticeable rise in black levels during the day.
