Samsung S90F OLED 4K TV vs LG C3 65-Inch OLED TV

The LG C3 is the better pick for most people: it is 10 inches larger, supports Dolby Vision and Dolby Atmos, and runs webOS with the well-liked Magic Remote. The Samsung S90F is the sharper choice for a bright room or a smaller wall, since QD-OLED resists burn-in better and Samsung's anti-glare coating handles daylight well. Owners of both praise the deep blacks and 120Hz gaming; the LG's stand is wide and its peak brightness is lower than Samsung's, while the Samsung gives up Dolby Vision and a size class.

  • Choose the Samsung S90F if you sit closer than about 8 feet, watch in a bright room, or want the punchier highlights and stronger burn-in resistance of QD-OLED.
  • Choose the LG C3 if you want the bigger 65-inch picture, Dolby Vision and Dolby Atmos, and the friendlier webOS interface with the Magic Remote.

What reviewers say

Samsung S90F OLED 4K TV

Owners of Samsung's S90-series OLEDs praise the picture, especially blacks and contrast, and call it good value against the brighter flagship. Complaints center on brightness in sunny rooms and on reflections.

What people mention
  • Picture qualityPraisedOwners say blacks are deep and contrast is strong for the price.
  • BrightnessMixedFine in most rooms, but reviewers say it trails the S95F in bright light.
  • ReflectionsCriticisedThe glossy screen shows reflections without the flagship's anti-glare layer.
  • ValuePraisedBuyers see it as the sensible pick below Samsung's top OLED.

LG C3 65-Inch OLED TV

Reviewers and owners rate the C3 as one of the best-value OLEDs of its generation, praising picture quality and gaming features. Complaints center on brightness in bright rooms, burn-in worry and weak built-in sound.

What people mention
  • Picture qualityPraisedOwners call the contrast and black levels the main reason to buy it.
  • BrightnessMixedFine in most rooms, but reviewers say it dims next to brighter Mini-LED sets in daylight.
  • GamingPraisedFour HDMI 2.1 ports and low lag are repeatedly cited by console players.
  • Burn-inCriticisedSome owners worry about static logos and tickers leaving marks over time.

Questions and answers

Which is better for a bright living room?
The Samsung S90F. QD-OLED pushes higher highlights and its anti-glare coating cuts reflections, so daytime sports and news hold up better. The LG C3 is dimmer but still fine in a room with blinds.
Which is better for movies?
The LG C3, mainly for Dolby Vision and Dolby Atmos. If your player or streaming service outputs Dolby Vision, the C3 uses it and the S90F does not. The Samsung wins on raw highlight punch in HDR10 content.
Which lasts longer?
Both are rated for years of normal use, but QD-OLED in the S90F has a lower burn-in risk with static logos, tickers and game HUDs. The C3 is more vulnerable to permanent image retention if you leave news channels or scoreboards on for hours daily.
Is the LG C3 worth stepping up to over the Samsung?
If you want the larger 65-inch picture and Dolby Vision, yes. If your room is bright, your seating is close, or you mostly game, the Samsung's brightness and burn-in resistance matter more than the size gap.
Which is better for gaming?
They are close. Both do 120Hz over four HDMI 2.1 ports with low input lag. The LG adds G-Sync and FreeSync certification and a fuller Game Optimizer menu; the Samsung counters with a brighter image and its Game Bar overlay.
Do I need a wall mount for either?
The LG C3's stand is 56.7 inches wide, so it needs a wide console or a wall mount. The Samsung S90F uses a centered pedestal that fits narrower furniture.
