Our Verdict

Samsung S90D OLED

LG G4 OLED

The LG G4 OLED and the Samsung S90D OLED are both amazing TVs, but there are some differences worth noting. The Samsung has a wider color gamut, so it can display more vibrant and lifelike colors, and it has better color volume, so it can display brighter colors. The S90D also has no noticeable banding in colors, while the LG does have some banding in certain colors. On the other hand, the LG has better low-quality content smoothing, so it's the better choice if you regularly watch DVDs or low-quality streams. The LG also supports both Dolby Vision and DTS audio formats, which is great if you're looking to get the most out of your 4k Blu-ray collection. On top of that, the LG has better SDR brightness, so it overcomes more glare in a bright room.
