Our Verdict
Samsung S90D OLED
LG G5 OLED
The LG G5 OLED is brighter and more versatile than the Samsung S90D OLED. Its tandem-WOLED panel gives it brighter highlights than the Samsung, and it preserves that punch in larger bright scenes, so it shrugs off glare and makes highlights pop. The LG also supports Dolby Vision and accepts 4k @ 165Hz signals on every HDMI 2.1 port, which is ideal for modern consoles and high FPS PC gaming. The Samsung fights back with its QD-OLED panel's wider color gamut and higher color volume, but it's barely noticeable. The Samsung also has cleaner HDR gradients, so dark-room movies look richer and virtually banding-free, and it does handle ambient reflections a bit better. Overall, though, the LG is the better OLED.
