LG C6 65" OLED evo TV vs Samsung QN65S90HAEXZA S90H 65 Inch 4K OLED TV

Both are 65-inch 4K OLEDs with 165Hz gaming support, four HDMI ports and AI upscaling, so the picture quality gap is small. The LG C6 leans on Dolby Vision, four full HDMI 2.1 inputs and a brighter evo panel, which suits movie watchers and console gamers who want every format covered. The Samsung S90H counters with a glare-free coating, Dolby Atmos with object tracking and a wider set of voice assistants, which suits bright rooms and mixed-use living spaces. Owners rate the Samsung highly across a much larger pool of ratings; the LG's sample is small, so treat its score with caution.

  • Choose the LG C6 if you watch Dolby Vision movies, own a PS5 or Xbox, or want four full HDMI 2.1 ports and the deepest blacks in a dark room.
  • Choose the Samsung S90H if your room has windows or lamps facing the screen, or you want glare-free viewing plus Bixby, Alexa and Google built in.

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 window and lamp reflections that the LG C6's glossy panel shows. The LG wins in a dark, light-controlled room where deep blacks matter most.
Which is better for PS5 and Xbox Series X?
Both handle 4K at 120Hz with VRR. The LG C6 gives you four full HDMI 2.1 ports, so you can leave a console, a PC and a soundbar connected without swapping cables. The Samsung has four HDMI inputs but fewer at full 2.1 bandwidth.
Do I lose anything without Dolby Vision on the Samsung?
Yes, on Dolby Vision discs and streams. The Samsung falls back to HDR10, which is still strong but lacks dynamic per-scene metadata. If most of your viewing is Dolby Vision content, the LG C6 is the safer pick.
Which has better sound out of the box?
The LG C6. Its 2.2-channel 40W system with AI Sound Pro up-mixing fills a room better than the Samsung's 2.1 array. Both support Dolby Atmos, and either benefits from a soundbar for serious movie nights.
Is the Samsung worth stepping up to over the LG?
Only if glare or voice assistants decide it for you. The Samsung adds the glare-free layer and Bixby, Alexa and Google. The LG adds Dolby Vision and a fourth full HDMI 2.1 port. Picture quality is close on both.
Which lasts longer?
Neither brand publishes a lifespan figure, and OLED panels from both age similarly with static logos and news tickers. Burn-in risk depends more on your viewing habits than on the brand. The Samsung's larger owner base gives more long-term feedback to judge by.
