Samsung S84F 55" OLED 4K TV vs LG C6 Series OLED TV (65")

The LG C6 is the better buy for most people. It gives you a 65-inch panel instead of 55, a 2.2-channel speaker system with four speakers, Siri support, and a much larger owner base: 4.8 from about 900 ratings versus 4.7 from 58. The Samsung S84F counters with a slimmer bezel, top-firing speakers, HDR10+ support, and Bixby built in. Both are 120 Hz OLEDs with four HDMI ports, so the real decision is screen size and sound versus Samsung's design and assistant ecosystem.

  • Choose the Samsung S84F if you want a 55-inch OLED with a thin bezel, top-firing Dolby Atmos speakers, and Bixby plus Alexa built in.
  • Choose the LG C6 if you want the larger 65-inch screen, stronger built-in audio, Siri support, and a longer track record of owner ratings.

What reviewers say

Samsung S84F 55" OLED 4K TV

  • 4.7 / 558 ratings

Rated 4.7 out of 5 from 58 ratings, buyers are largely pleased with the picture and design. Complaints center on brightness in bright rooms and built-in sound.

What people mention
  • Picture qualityPraisedOwners highlight deep blacks and vivid color from the OLED panel.
  • BrightnessCriticisedSome say the set struggles in bright, sunlit rooms.
  • SoundMixedDolby Atmos helps, but built-in speakers are called thin for big movies.
  • DesignPraisedThe slim profile and thin bezel are frequently complimented.

LG C6 Series OLED TV (65")

  • 4.8 / 5900 ratings

With 4.8 out of 5 from 900 ratings, owners are largely very happy with the C6's picture and gaming features. Complaints tend to be about brightness in bright rooms and the built-in sound rather than the panel itself.

What people mention
  • Picture qualityPraisedOwners describe deep blacks, rich color and strong contrast, especially in dim rooms.
  • GamingPraisedReviewers like the 120Hz panel, VRR and four HDMI 2.1 ports for consoles and PCs.
  • BrightnessMixedSome find it bright enough for most rooms; others say a sunlit room washes out the picture.
  • SoundCriticised

Questions and answers

Which is better for a bright living room?
Neither is the obvious pick for a very bright room, since OLED panels trade some peak brightness for contrast. The Samsung adds HDR10+ and claims enhanced brightness, but the LG's larger screen and stronger speakers matter more for most living rooms.
Which has better built-in sound?
The LG C6. It uses a 2.2-channel system with four speakers, while the Samsung S84F has two speakers, though it does add top-firing drivers and Dolby Atmos.
Is the LG worth stepping up to over the Samsung?
For most shoppers, yes. You get a 65-inch screen instead of 55, better audio, and Siri alongside Alexa and Google Assistant. Step down to the Samsung if you want the slimmer design, HDR10+ or Bixby.
Which is better for gaming?
Both are 120 Hz OLEDs with four HDMI ports, so they are close. The LG lists a 0.1 ms response time, which suits fast action, and its larger screen makes split-screen play easier to follow.
Which lasts longer?
Neither maker publishes a lifespan figure, and both use self-lit OLED panels. The LG has a much larger pool of owner ratings, which gives more evidence about reliability over time.
Do both support voice assistants?
Yes. The Samsung has Bixby and Alexa, and the LG adds Siri on top of Alexa and Google Assistant.
