LG C6 Series OLED 4K Smart TV vs Samsung QN77S85F 77" OLED TV

Both are 77-inch OLEDs with 120 Hz panels and Dolby Atmos, so the picture fundamentals are close. The LG C6 adds Dolby Vision, a brighter evo panel with Brightness Booster Pro, and four full HDMI 2.1 ports, which matters most for movie fans and console gamers. The Samsung S85FAE counters with HDR10+ and Samsung's anti-glare coating, and owners rate it highly. Buy the LG for Dolby Vision content and gaming features; buy the Samsung if you watch in a bright room or live in the Samsung SmartThings ecosystem.

  • Choose the LG C6 if you want Dolby Vision, the brightest OLED panel of the two, and four HDMI 2.1 ports for a PS5 or Xbox Series X.
  • Choose the Samsung S85FAE if your room gets a lot of daylight, you prefer Samsung's anti-glare screen and Tizen apps, or you already use SmartThings.

What reviewers say

LG C6 Series OLED 4K Smart TV

Owners and reviewers highlight the C6 as a major step forward for bright-room OLED performance thanks to the Alpha 11 processor. It is praised for its color accuracy and gaming features, though its weight and long-term pixel care remain standard OLED considerations.

What people mention
  • BrightnessPraisedThe Brightness Booster Pro technology makes this set significantly more visible in sunlit rooms than previous generations.
  • ProcessingPraisedThe Alpha 11 AI Processor Gen3 is noted for providing a smoother, more personalized experience without lag.
  • BuildMixedWhile the flat screen is sleek, the 84 lb weight of the 77-inch unit makes mounting a heavy-duty task.

Samsung QN77S85F 77" OLED TV

  • 4.8 / 5439 ratings

Rated 4.8 out of 5 from 439 ratings, buyers are largely very happy with the picture and size. Most praise centers on OLED contrast and color, with a few noting brightness limits in bright rooms.

What people mention
  • Picture qualityPraisedOwners call the OLED contrast and color the standout, especially for movies in dim rooms.
  • BrightnessMixedSome say it is bright enough for most rooms, while others find it dimmer than QLED rivals in daylight.
  • SizePraisedBuyers describe the 77-inch screen as immersive and a big step up from 65-inch sets.
  • ReflectionsCriticisedA few owners note the glossy screen picks up window and lamp reflections.

Questions and answers

Which is better for a bright living room?
The Samsung. Its anti-glare coating handles daylight and lamp reflections better. The LG has the brighter panel, but its glossy screen reflects more.
Which is better for PS5 and Xbox Series X?
The LG C6. It has four HDMI 2.1 ports at 120 Hz with VRR and ALLM, so you can keep a console, a PC and a soundbar connected without swapping cables.
Do I lose much without Dolby Vision on the Samsung?
Yes, on Dolby Vision titles from Netflix, Disney+ and most 4K discs. Those play in HDR10 on the Samsung, which looks good but lacks the dynamic per-scene metadata.
Which lasts longer?
Both use self-lit OLED pixels with similar lifespans. The LG adds an OLED Care routine that helps protect the panel, but neither has a clear durability edge over the other.
Is the LG worth stepping up to?
If you watch Dolby Vision movies or game on a console, yes. If your room is bright or you want the lowest outlay, the Samsung covers the basics well.
Do either include a wall mount?
The LG C6 includes a mount in the box. The Samsung is VESA compatible but the mount is sold separately.
