LG OLED B6 Series 65-Inch TV vs Samsung S90F OLED 4K TV

The LG B6 is the bigger set at 65 inches and the better fit for a bright living room or a mixed household, thanks to four HDMI 2.1 ports, Dolby Vision and Dolby Atmos. The Samsung S90F is a 55-inch OLED with the same 120Hz panel class and a slimmer, simpler feature set. Both deliver true black and wide viewing angles, and owners of both lines praise the picture; the LG adds more gaming ports and more HDR formats, while the Samsung suits a smaller room or a buyer who wants a compact OLED.

  • Choose the LG B6 if you want a 65-inch OLED with four HDMI 2.1 ports, Dolby Vision and Dolby Atmos for movies and consoles.
  • Choose the Samsung S90F if you need a smaller 55-inch OLED for a tighter room and do not need four next-gen HDMI inputs.

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.

Samsung S90F OLED 4K TV

Owners of Samsung's S90-series OLEDs praise the picture, especially blacks and contrast, and call it good value against the brighter flagship. Complaints center on brightness in sunny rooms and on reflections.

What people mention
  • Picture qualityPraisedOwners say blacks are deep and contrast is strong for the price.
  • BrightnessMixedFine in most rooms, but reviewers say it trails the S95F in bright light.
  • ReflectionsCriticisedThe glossy screen shows reflections without the flagship's anti-glare layer.
  • ValuePraisedBuyers see it as the sensible pick below Samsung's top OLED.

Questions and answers

Which is better for a bright living room?
The LG B6, mainly because it is larger and lists Dolby Vision plus a 40W Atmos speaker system. OLED black levels are similar on both, but neither is as bright as a high-end LCD in direct sun.
Which is better for gaming?
The LG B6. It lists four HDMI 2.1 ports, VRR, G-Sync, FreeSync Premium and a 0.1ms response time. The Samsung has a 120Hz panel but its gaming features are not detailed.
Is the LG worth stepping up to over the Samsung?
If you have the wall space, yes. You get 10 more inches, two more HDR formats and more console-ready ports. If the room is small, the 55-inch Samsung is the more sensible fit.
Which lasts longer?
Both are OLED, so both can show image retention if a static logo sits on screen for hours. Neither brand publishes a lifespan figure; normal mixed viewing is fine on either.
Do both support voice assistants?
Yes. The LG lists Alexa, Hey Google and Apple AirPlay. The Samsung lists Amazon Alexa support.
Which has better sound out of the box?
The LG B6, which lists a 40W 4.0-channel system with Dolby Atmos. Samsung does not detail the S90F's audio output, so a soundbar is the safer bet there.
