LG C1 55" OLED 4K TV vs Samsung S90H OLED 65" TV

The LG C1 is the safer pick for most people. It is a 55-inch OLED with four HDMI 2.1 ports, G-Sync and FreeSync Premium, and a long track record: 4.6 out of 5 from about 3,300 ratings. The Samsung S90H is a 65-inch OLED with Dolby Atmos and HDR10+, so it gives you a bigger picture for the same kind of money. The C1 wins on gaming features and proven reliability; the S90H wins on size and sound format.

  • Choose the LG C1 if you game on a console or PC and want four HDMI 2.1 ports, G-Sync and FreeSync, and a set with years of owner feedback behind it.
  • Choose the Samsung S90H if you sit far from the screen and want the extra 10 inches of OLED, with Dolby Atmos and HDR10+ for movies.

What reviewers say

LG C1 55" OLED 4K TV

  • 4.6 / 53,300 ratings

Owners rate it highly, at 4.6 out of 5 from about 3,300 ratings, and praise the picture, especially black levels and gaming features. Complaints center on brightness in bright rooms and the risk of burn-in.

What people mention

  • GamingPraisedReviewers like the 120 Hz refresh, low input lag and G-SYNC/FreeSync support.
  • BrightnessCriticisedSome owners find it dimmer than expected in bright, sunlit rooms.
  • Burn-inMixedSome buyers worry about image retention from logos and news tickers.

Samsung S90H OLED 65" TV

Owners of Samsung's OLED sets generally praise the contrast, color and slim build, and call the Tizen interface easy to live with. Common complaints center on brightness in sunlit rooms, reflections, and the lack of Dolby Vision.

What people mention
  • Picture contrastPraisedOwners say dark scenes look deep and colors stay vivid.
  • BrightnessMixedFine in dim rooms, but some find it dimmer than top OLED rivals in daylight.
  • ReflectionsCriticisedThe glossy screen picks up lamps and windows in bright rooms.
  • SoundCriticisedBuilt-in speakers are described as thin, so many add a soundbar.

Questions and answers

Which is better for PS5 and Xbox Series X?
The LG C1. It has four HDMI 2.1 ports, G-Sync and FreeSync Premium, and a Game Optimizer, so you can run 4K at 120 Hz on a console and a PC without swapping cables.
Is the Samsung worth stepping up to for the bigger screen?
If you sit more than about 8 feet away, yes. The 65-inch S90H fills more of your view, and the picture quality is close. If you game heavily, the C1's ports and VRR support matter more than the extra size.
Which handles dark movie scenes better?
Both are OLED, so both give true black and strong contrast. The C1 adds Dolby Vision, which helps on Dolby Vision discs and streams. The S90H adds Dolby Atmos, which helps only if you have the sound system to use it.
Which lasts longer?
Neither is proven longer-lived. OLED panels can develop image retention from static logos and news tickers. The C1 has years of owner reports to judge by; the S90H is too new for that.
Do I need a soundbar with either?
Yes, for serious movie sound. The C1's AI Sound Pro is decent for dialogue, and the S90H supports Dolby Atmos, but neither matches a separate soundbar or speakers.
Which is better in a bright room?
Neither is the strongest choice. OLED brightness is lower than the brightest LCD sets, and both can reflect glare. The C1's anti-glare coating is well regarded, but a bright room still favors a bright LCD.
