LG C6 65" OLED evo TV vs Samsung QN65S90HA 65" OLED TV

Both are 65-inch 4K OLEDs with 120Hz panels, four HDMI 2.1 ports and strong gaming features, so the picture quality is close. The LG C6 leans on Dolby Vision, a 2.2-channel 40W speaker system and webOS, while the Samsung S90H counters with HDR10+, a glare-free coating, Wi-Fi 6E and a slimmer design. Buyers who watch a lot of Dolby Vision movies and want fuller built-in sound tend to favor the LG; buyers in bright rooms or deep in the Samsung ecosystem tend to favor the Samsung.

  • Choose the LG C6 if you watch Dolby Vision content, want stronger built-in speakers and prefer webOS with AirPlay and Chromecast built in.
  • Choose the Samsung S90H if your room gets a lot of daylight, you want HDR10+ and Wi-Fi 6E, or you already use Samsung phones, soundbars and SmartThings.

What reviewers say

LG C6 65" OLED evo TV

  • 5 / 511 ratings

Ratings are very high, 5 out of 5 from 11 ratings, though the sample is small. Owners praise the picture and gaming features; the recurring caveats are brightness in bright rooms and built-in sound.

What people mention
  • Picture qualityPraisedOwners rate the contrast and color highly, calling the blacks perfect.
  • GamingPraised120Hz with VRR and G-Sync/FreeSync support is a draw for console and PC players.
  • BrightnessMixedBrightness Booster helps, but some find it dimmer than LED sets in a bright room.
  • SoundCriticisedThe 40W speakers are seen as weak for the size, pushing buyers toward a soundbar.

Questions and answers

Which is better for a bright living room?
The Samsung S90H. Its Glare Free coating suppresses reflections far better than the LG's glossy panel, and OLED blacks hold up in daylight. The LG looks better in a dark room where Dolby Vision shines.
Which has better sound without a soundbar?
The LG C6. Its 2.2-channel 40W system with AI Sound Pro up-mixing produces more bass and width. The Samsung's 2.1-channel setup is fine for news but thin for movies.
Which is better for gaming?
They are close. Both do 120Hz native with VRR, G-Sync and FreeSync, and four HDMI 2.1 ports. The Samsung adds FreeSync Premium Pro, a game bar and cloud gaming through Gaming Hub; the LG claims a 0.1ms response time.
Do I lose much without Dolby Vision on the Samsung?
Yes on Netflix and Disney+ titles mastered in Dolby Vision, which fall back to HDR10. The Samsung's HDR10+ helps on Amazon Prime Video. If most of your watching is Dolby Vision, the LG is the safer pick.
Is the step up worth it for either?
Only if a specific feature matters to you: Dolby Vision and sound on the LG, or the glare-free screen and Wi-Fi 6E on the Samsung. Otherwise both deliver similar OLED contrast and gaming performance.
Which lasts longer?
Both use self-lit OLED panels with similar lifespans and both carry manufacturer warranties. Neither has a documented durability edge; panel care settings and how bright you run the set matter more than the brand.
