Samsung S90D OLED 4K TV vs LG OLED65C5 65-inch OLED TV

Both are OLED 4K smart TVs with 120Hz-plus panels, wide viewing angles and infinite contrast. The LG C5 is the larger set at 65 inches, adds a 144Hz refresh rate, four HDMI ports and an anti-glare coating, and its webOS platform is widely praised for gaming features like VRR and low input lag. The Samsung S90D is the sharper pick for bright rooms and Samsung ecosystem owners, with strong AI upscaling and Pantone-validated color, though its Tizen setup and account requirements draw more complaints. Buy the LG for size and gaming; buy the Samsung for punchy brightness and a smaller footprint.

  • Choose the Samsung S90D if you want a 55-inch OLED with bright, punchy highlights, strong AI upscaling and tight integration with Samsung phones and SmartThings.
  • Choose the LG C5 if you want the bigger 65-inch picture, a 144Hz panel with VRR for gaming and four HDMI ports.

What reviewers say

Samsung S90D OLED 4K TV

Owners of the S90D generally praise the picture, especially blacks and contrast, and find it a strong value among OLED TVs. Complaints center on brightness in bright rooms, image retention worries, and sound quality.

What people mention
  • Picture qualityPraisedOwners describe deep blacks, strong contrast and vivid color.
  • BrightnessMixedFine in dim rooms, but some find it dimmer than QD-OLED and Mini-LED sets in bright rooms.
  • Burn-inCriticisedSome owners worry about image retention from news tickers, logos and game HUDs.
  • SoundCriticisedBuilt-in speakers are called thin, so many buyers add a soundbar.

LG OLED65C5 65-inch OLED TV

  • 4.2 / 5273 ratings

Owners rate the C5 highly for picture quality and gaming features, with an average of 4.2 out of 5 from 273 ratings. Complaints center on brightness in bright rooms and OLED care settings.

What people mention
  • Picture qualityPraisedOwners call the contrast and color the main reason to buy.

  • GamingPraised144Hz VRR and low latency are repeatedly called out by console and PC players.

Questions and answers

Which is better for gaming?
The LG C5. It has a 144Hz panel, VRR and four HDMI 2.1 ports, which suits PS5 and Xbox Series X at high frame rates. The Samsung S90D is close at 120Hz but has fewer gaming-focused extras.
Which is better for a bright living room?
The Samsung S90D handles highlights more aggressively and its OLED HDR+ processing helps in mixed light. The LG C5's anti-glare coating reduces reflections, so it depends on whether you fight glare or want punch.
Is the LG C5 worth stepping up to over the Samsung?
If you want the larger 65-inch picture and 144Hz gaming, yes. If you sit close and prefer a brighter, more saturated image, the Samsung is the better fit.
Which lasts longer?
Both use OLED panels with similar lifespans under normal use. The LG C5 is discontinued, so replacement parts and firmware support may end sooner than for the current Samsung S90D.
Do both work with Alexa and Google Assistant?
Yes. Both list Google Assistant and Amazon Alexa support, and both have built-in voice control through their remotes.
Which has better smart TV software?
LG's webOS is generally preferred for speed and gaming menus. Samsung's Tizen is capable but requires a Samsung Account for most streaming apps.
