LG C6 Series OLED evo 4K TV vs Samsung S90H OLED 4K Smart TV

The Samsung S90H is the safer pick for most people: it has a glare-free panel, strong anti-reflection coating, and a much larger owner base behind its rating. The LG C6 wins on gaming flexibility with four full HDMI 2.1 ports, Dolby Vision, and refresh up to 165Hz, plus wider voice control support. Both are OLED with excellent contrast; the LG leans toward gamers and Dolby Vision movie fans, the Samsung toward bright rooms and everyday streaming.

  • Choose the LG C6 if you game on PC or console and want Dolby Vision, four HDMI 2.1 ports, and the widest assistant support.
  • Choose the Samsung S90H if your room has windows or lamps that reflect on the screen and you want glare-free viewing with proven owner feedback.

Questions and answers

Which is better for gaming, the LG C6 or the Samsung S90H?
The LG C6 edges ahead with four HDMI 2.1 ports and refresh up to 165Hz, plus Dolby Vision for supported games. The Samsung S90H still handles 4K 120Hz with G-Sync and FreeSync Premium Pro, so console players will be fine with either.
Which handles a bright room better?
The Samsung S90H. Its Glare Free coating is designed to cut reflections from windows and lamps, which is the usual weak spot for OLED. The LG C6 has no anti-glare feature called out.
Is Dolby Vision worth stepping up to the LG C6 for?
If you watch a lot of Dolby Vision movies and shows, yes. The Samsung S90H supports HDR10+ instead, and its Auto HDR Remastering improves SDR content, but it will not play Dolby Vision titles at their best.
Which lasts longer?
Both are OLED, so both carry the same long-term risk of image retention from static logos and tickers. Neither brand publishes a panel lifespan figure here. Varying content and using screen-shift settings matters more than the brand choice.
Which has better sound out of the box?
The Samsung S90H. Object Tracking Sound Lite moves audio with on-screen objects, and Active Voice Amplifier Pro lifts dialogue. The LG C6 relies on Precision Sound Master Pro, which is more conventional processing.
Do both support the same voice assistants?
No. The LG C6 works with Alexa, Google, Siri and Apple HomeKit. The Samsung S90H covers Bixby, Alexa and Google, so Apple HomeKit users should lean LG.
