Our Verdict

LG G3 OLED

Samsung S90D OLED

The LG G3 OLED and the Samsung S90D OLED are similar TVs, each with their own strengths. The LG gets brighter in SDR, so it overcomes more glare in a bright room. The LG also does a better job at smoothing out low-quality content, so if you regularly watch DVDs or lower-quality streams, it's the better option for that. If you're a fan of physical media, the LG is the better option due to its Dolby Vision and DTS audio support. On the other hand, the Samsung has better HDR brightness, so highlights in HDR content pop a little more on it, and its better color volume means it can display brighter colors. If you're a PC gamer, the Samsung supports up to 4k @ 144Hz, so it's the better TV to pair with PCs that have high-end graphics cards.
