LG OLED B6 Series 65-Inch TV vs Samsung S85F OLED 4K Smart TV

The LG B6 is the better pick for most people deciding between these two. It is 10 inches larger, has four full HDMI 2.1 ports, and supports Dolby Vision, which the Samsung lacks. The Samsung S85FA is a solid OLED with a bright, punchy picture and Tizen's app selection, but it is smaller and its HDR support tops out at HDR10+. Owners of both praise the deep blacks and wide viewing angles; the LG's webOS and gaming features get more consistent praise than Samsung's Bixby voice control.

  • Choose the LG B6 if you want the biggest OLED picture for a living room, need Dolby Vision and four HDMI 2.1 ports for a console and a PC, and care about gaming features like G-Sync, FreeSync Premium and a 0.1ms response time.
  • Choose the Samsung S85FA if your room only fits a 55-inch set, you prefer Tizen and its app lineup, and you want a Samsung panel with Dolby Atmos and a wide 178-degree viewing angle.

What reviewers say

LG OLED B6 Series 65-Inch TV

Owners of LG's B-series OLEDs praise the picture in dark rooms and the gaming features for the price. The recurring complaint is brightness in daylight and reflections on the glossy screen.

What people mention
  • Picture qualityPraisedOwners say the OLED panel delivers deep blacks and strong contrast, especially in dim rooms.
  • BrightnessCriticisedReviewers note the B series is dimmer than LG's C and G models and struggles in bright rooms.
  • GamingPraisedFour HDMI 2.1 ports at 4K 120Hz and low lag are called out as strong for the price.
  • ReflectionsCriticisedThe glossy screen shows reflections from windows and lamps.

Questions and answers

Which is better for a bright living room?
Both are OLED, so neither is the brightest option. The LG's a8 processor and AI brightness handling make it the more balanced pick for mixed lighting, while the Samsung's punchy tuning suits darker rooms. Neither matches a bright mini-LED LCD in a sunlit room.
Which is better for gaming?
The LG B6. It lists four HDMI 2.1 ports, 120Hz, VRR, G-Sync, FreeSync Premium, a 0.1ms response time and a Game Optimizer dashboard. The Samsung has a 120Hz panel but does not detail 2.1 or VRR support.
Is the LG worth stepping up to over the Samsung?
Yes for most buyers. You get 10 more inches, Dolby Vision and clearer gaming specs. Step down to the Samsung only if a 55-inch screen is the right fit for your room or you specifically want Tizen.
Which lasts longer?
Both use OLED panels with similar lifespans, and neither maker publishes a rated hour count here. LG's webOS gets longer, more consistent software updates in owner reports, which helps the LG stay useful longer.
Does the Samsung support Dolby Vision?
No. The S85FA lists HDR10+ and Dolby Atmos but not Dolby Vision. The LG B6 supports Dolby Vision, HDR10 and HLG, so Dolby Vision discs and streams look their best on the LG.
Which has better sound without a soundbar?
The LG B6, with a stated 40W 4.0-channel system and Dolby Atmos. The Samsung supports Dolby Atmos processing but does not state its wattage or channel count, so the LG's built-in audio is the safer bet.
