LG B6E Series OLED 4K Smart TV vs Samsung S84F 55" OLED 4K TV

Both are 55-inch 120Hz OLED 4K TVs with four HDMI ports, and either is a strong pick. The LG B6E has the edge for movie nights: it supports Dolby Vision as well as HDR10 and HLG, and its webOS platform carries the full app lineup. The Samsung S84F counters with HDR10+ and a solar-powered remote, but its listing names fewer streaming apps and no Dolby Vision. Owners rate the LG slightly higher (4.8 from 116 ratings vs 4.7 from 58), though both sets are well liked.

  • Choose the LG B6E if you watch a lot of Dolby Vision movies and shows, want Google Assistant and Apple Home support, or care about gaming features like G-Sync and FreeSync Premium.
  • Choose the Samsung S84F if you prefer HDR10+ content, want Bixby and Alexa built in, or like the idea of a remote that charges from indoor light.

Questions and answers

Which is better for movies?
The LG B6E, mainly because it supports Dolby Vision alongside HDR10 and HLG. Most 4K Blu-rays and many streaming titles use Dolby Vision, and the Samsung S84F does not list it. The Samsung's top-firing speakers give it an edge on built-in sound.
Which is better for gaming?
The LG B6E. Both run at 120Hz, but the LG adds NVIDIA G-Sync, AMD FreeSync Premium and a 0.1ms response time, which reduce screen tearing on PCs and consoles. The Samsung listing names no variable refresh tech.
Which lasts longer?
Neither brand publishes a lifespan figure, and both use OLED panels that can dim over many years of heavy use. The LG's higher owner rating from more ratings is the better signal you have. Buy the extended warranty if you plan to keep either set past five years.
Is the Samsung worth stepping up to over the LG?
Only if HDR10+ and built-in Bixby or Alexa matter more to you than Dolby Vision and gaming sync features. On picture formats and gaming the LG is the more complete set. On sound and the remote the Samsung is ahead.
Do both have four HDMI ports?
Yes, both list four HDMI inputs, which covers a console, a soundbar, a streaming box and a spare. Neither listing specifies HDMI 2.1 on every port, so confirm that if you need 4K at 120Hz from a console.
Which has better smart TV apps?
The LG B6E lists Netflix, Prime Video, Disney+, HBO Max, Apple TV and 400+ free channels on webOS. The Samsung runs Tizen, which has a full app store, but its listing names only Netflix, so check for the apps you use before buying.
