Samsung S84D OLED 4K Smart TV vs LG OLED evo C5 4K Smart TV

The LG OLED evo C5 is the stronger pick for most people: it is a generation newer, has a 144Hz panel with VRR, an anti-glare coating, and four HDMI ports. The Samsung S84D is a solid OLED with 120Hz and a wide app and assistant ecosystem, but it trails on gaming refresh rate and glare handling. Reviewers and owners praise LG's evo panel brightness and processing; Samsung's S84D gets credit for color and design but is seen as the entry OLED in its lineup.

  • Choose the Samsung S84D if you want a 77-inch OLED with Google Assistant and Alexa built in and you mostly watch movies and shows rather than competitive games.
  • Choose the LG OLED evo C5 if you game, watch in a bright room, or want the newer panel and the extra HDMI inputs.

What reviewers say

Samsung S84D OLED 4K Smart TV

Owners of Samsung's OLED sets praise the contrast, motion and design, and most find the picture a clear step up from LED. Common complaints are brightness in bright rooms and the lack of Dolby Vision.

What people mention
  • Picture qualityPraisedOwners say the OLED panel gives deep blacks and rich contrast that LED sets cannot match.
  • BrightnessCriticisedReviewers note it dims next to QD-OLED and Mini-LED rivals in a bright room.
  • MotionPraisedThe 120 Hz panel is described as smooth for sports and fast action.
  • Dolby VisionCriticisedBuyers miss Dolby Vision, since the set handles HDR10 and HDR10+ only.

LG OLED evo C5 4K Smart TV

Owners of LG's C-series OLEDs generally praise the picture quality, contrast and gaming features. Common complaints center on brightness in very bright rooms and the care needed to avoid static-image burn-in.

What people mention
  • Picture qualityPraisedOwners say the OLED panel delivers deep blacks and strong contrast.
  • BrightnessMixedReviewers find it bright enough for most rooms but behind the brightest LCDs in daylight.
  • GamingPraisedThe 144Hz refresh rate and VRR are called smooth for console and PC play.
  • Burn-inCriticisedSome owners worry about static logos and news tickers leaving marks over time.

Questions and answers

Which is better for gaming?
The LG C5. Its 144Hz panel and VRR support give smoother motion and less tearing than the Samsung's 120Hz set.
Which handles a bright room better?
The LG C5, which lists an anti-glare coating. The Samsung S84D does not list one.
Is the LG worth stepping up to over the Samsung?
For gamers and bright rooms, yes: newer panel, higher refresh rate, VRR and anti-glare. For movie watching in a dark room, the Samsung is close.
Which has better voice control?
The Samsung S84D lists both Google Assistant and Amazon Alexa. The LG C5 does not list either.
How much bigger is the LG?
Six inches diagonally, 83 versus 77. That is a noticeable jump in picture area, but it needs more wall space.
Which lasts longer?
Both are OLED and age similarly. The LG is a year newer, so its panel and processing are more current.
