Samsung S90D 65" 4K OLED TV vs LG C5 77-inch OLED TV

The LG C5 is the better TV for most people. It has a larger 77-inch panel, the newer 2025 evo panel with Dolby Vision, and the stronger a9 Gen8 processor. The Samsung S90D is a solid OLED with 144Hz motion and a lower-glare coating, but it is a 2024 model and this listing is factory reconditioned. Owners of both praise the deep blacks and color; LG buyers consistently call the C5 one of the most color-accurate sets they have owned.

  • Choose the Samsung S90D if you sit close, want the smoother 144Hz motion for gaming, and prefer a matte anti-glare screen in a bright room.
  • Choose the LG C5 if you want the bigger 77-inch picture, Dolby Vision support, and the latest processor and panel generation.

What reviewers say

Samsung S90D 65" 4K OLED TV

  • 4.3 / 513,000 ratings

Rated 4.3 out of 5 across about 13,000 ratings, the S90D is generally well liked for its picture and gaming features. Complaints center on brightness in bright rooms, sound quality and the lack of Dolby Vision.

What people mention
  • Picture qualityPraisedOwners praise the deep blacks, contrast and saturated color on the OLED panel.
  • MotionPraisedThe 120Hz panel and motion processing are called smooth for sports and gaming.
  • BrightnessMixedSome find it bright enough, while others say it struggles in very bright rooms.
  • SoundCriticisedReviewers say the built-in speakers are weak and a soundbar is worth adding.

LG C5 77-inch OLED TV

Buyers describe the 77-inch C5 as one of the most color-accurate displays they have owned, with sharp detail that shines on movie nights. Longtime LG OLED owners say the line keeps improving year over year.

What people mention
  • Picture qualityPraisedOwners call it one of the most color-accurate displays they have used, with sharp detail at 77 inches.
  • BrightnessMixedBrightness Booster helps in lit rooms, but reviewers say it still trails the brightest QD-OLED and Mini-LED rivals.
  • SoundCriticisedThe 2-channel built-in speakers are described as thin, so many buyers add a soundbar.
  • GamingPraisedFour HDMI 2.1 ports at 120Hz with VRR make it a popular pick for console and PC gamers.

Questions and answers

Which is better for a bright living room?
The Samsung S90D. Its anti-glare coating cuts reflections, and OLED HDR+ boosts brightness per scene. The LG C5 is brighter than older OLEDs but has no listed anti-glare treatment.
Which is better for movies?
The LG C5. The 77-inch screen and Dolby Vision support give a bigger, more cinematic picture with frame-by-frame HDR. The Samsung lacks Dolby Vision.
Which is better for gaming?
The Samsung S90D. Its Motion Xcelerator reaches 144Hz for smoother fast motion. Both have 120Hz panels, four HDMI ports and low input lag.
Is the LG worth stepping up to over the Samsung?
Yes for most buyers. You get a 12-inch larger screen, a newer panel and processor, and Dolby Vision. Step down to the Samsung only if glare or 144Hz gaming matters more.
Should a factory reconditioned TV worry me?
Reconditioned sets are repaired and tested, but they are used units. Check the warranty length and return window before buying. The LG here is new.
Which lasts longer?
Both use OLED panels with similar lifespans, and neither brand publishes a firm hour rating. The LG is a newer panel generation, which usually means better long-term brightness retention.
