Samsung S90F OLED 4K Smart TV vs LG C6 Series OLED TV (65")

Both are 4K OLED sets with 120Hz panels and strong picture quality, so the choice comes down to size and use. The Samsung S90F is the pick for a large, bright living room or a mixed movie-and-gaming setup, with a 77-inch option and anti-glare coating. The LG C6 is the better all-rounder for most rooms: Dolby Vision and Dolby Atmos support, four HDMI 2.1 ports, and a 0.1ms response time make it the stronger gaming and film set. Owners of both praise the picture; Samsung buyers flag the higher cost, and LG buyers note the smaller size for the room.

  • Choose the Samsung S90F if you want a big 77-inch OLED with an anti-glare screen for a bright room and you watch a mix of movies and games.
  • Choose the LG C6 if you want the best gaming and film features, including Dolby Vision, Dolby Atmos and four HDMI 2.1 ports, in a 65-inch size.

LG C6 Series OLED TV (65")

  • 4.8 / 5900 ratings

Questions and answers

Which is better for gaming, the Samsung S90F or the LG C6?
The LG C6 edges ahead. It has a 0.1ms response time, native 120Hz with VRR up to 165Hz, and four HDMI 2.1 ports. The S90F is close with under-10ms lag and 144Hz VRR.
Does the Samsung S90F support Dolby Vision?
No. The S90F lists HDR10 and HLG but not Dolby Vision. The LG C6 supports Dolby Vision, so it is the better pick for Dolby Vision films and shows.
Which has better sound without a soundbar?
The LG C6. It has a 2.2-channel speaker system with Dolby Atmos. The S90F lists built-in speakers but no Dolby Atmos support.
Is the bigger Samsung screen worth stepping up to?
If you sit far from the TV or want a cinema feel, the 77-inch S90F is the larger set. The C6 is 65 inches, so the S90F wins on size, while the C6 wins on features.
Which handles a bright room better?
The Samsung S90F lists an anti-glare coating, which helps in a sunny room. The LG C6 does not list one, so reflections are more likely.
Do both work with voice assistants?
Yes. The S90F supports Bixby, Alexa and Google Assistant. The C6 supports Alexa, Google Assistant and Siri through webOS 26.
