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

Both are 65-inch OLEDs with 165Hz gaming support, four HDMI 2.1 ports and AI upscaling, so the picture and gaming gap is small. The LG C6 leans on Dolby Vision, a 0.1ms response time and 40W 2.2-channel sound with Dolby Atmos. The Samsung S90H counters with a glare-free coating, HDR10+ and a wider smart-home feature set. Buy the LG if you watch a lot of Dolby Vision movies or want the lowest input lag. Buy the Samsung if your room is bright or you want the deepest smart TV extras.

  • Choose the LG OLED evo C6 if you want Dolby Vision, near-zero input lag and strong built-in Atmos sound for movies and console gaming.
  • Choose the Samsung S90H if glare is a problem in your room or you want HDR10+, Wi-Fi 6E and a broader smart-home and health feature set.

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.

Samsung S90H 65" OLED 4K TV

Owners of Samsung's OLED TVs generally praise the deep blacks, contrast and slim build. Common complaints are reflections in bright rooms, the absence of Dolby Vision and lower peak brightness than the brightest QD-OLED sets.

What people mention
  • Picture contrastPraisedOwners say the OLED panel delivers deep blacks and strong contrast, especially in dark rooms.
  • BrightnessCriticisedReviewers note peak brightness is lower than the brightest QD-OLED rivals, so HDR highlights are less punchy.
  • ReflectionsCriticisedThe glossy screen shows reflections in bright, sunlit rooms, which owners find distracting.
  • HDR formatsMixedHDR10+ is supported, but the lack of Dolby Vision is a recurring complaint for streaming content.

Questions and answers

Which is better for a bright living room?
The Samsung S90H. Its Glare Free coating cuts reflections that the LG C6's glossy panel shows. The LG still wins on black level in a dark room.
Which has lower input lag for gaming?
The LG C6 lists under 0.1ms response time, the lowest figure of the two. Both run 165Hz VRR with four HDMI 2.1 ports, so either suits a console or PC.
Do both support Dolby Vision?
Only the LG C6. The Samsung S90H uses HDR10+ instead, so Dolby Vision discs and streams look best on the LG.
Which has better built-in sound?
The LG C6 on paper, with 40W across 2.2 channels. The Samsung S90H uses a 2.1-channel system with OTS Lite. A soundbar improves either one.
Is the Samsung worth stepping up to over the LG?
Only if glare or smart-home features matter most to you. On picture formats and gaming lag the LG is the stronger pick. Neither is a clear upgrade in raw image quality.
