Samsung OLED S90F 65" TV vs LG B5 Series OLED TV

Both are 65-inch 4K OLEDs with 120Hz panels and four HDMI 2.1 ports, so the picture basics are close. The Samsung S90F pushes higher peak brightness, a 144Hz refresh mode and Samsung's stronger AI upscaling, which suits bright rooms and gamers. The LG B5 adds Dolby Vision and Dolby Atmos, which the Samsung lacks, and owners consistently praise its deep blacks and sturdy build. Buy the Samsung for brightness and gaming headroom; buy the LG if Dolby Vision content and a simpler setup matter more.

  • Choose the Samsung S90F if you watch in a bright room, game at high frame rates, or want the brighter OLED panel and stronger upscaling.
  • Choose the LG B5 if you want Dolby Vision and Dolby Atmos support and a well-built OLED that owners say is easy to set up.

What reviewers say

Questions and answers

Which is better for a bright living room?
The Samsung S90F. Its OLED HDR+ panel reaches higher brightness, so reflections and daylight wash out the picture less. The LG B5 is dimmer on paper, though owners say it looks fine in normal rooms.
Does the LG B5 have Dolby Vision and the Samsung not?
Yes. The LG B5 supports Dolby Vision, HDR10 and HLG. The Samsung S90F supports HDR10+ and OLED HDR+ but not Dolby Vision, so Dolby Vision streams play in a fallback format.
Which is better for gaming?
The Samsung S90F. It runs up to 144Hz and has four HDMI 2.1 inputs. The LG B5 is capped at 120Hz but still offers VRR, ALLM and eARC on all four ports.
Is the LG B5 worth stepping up to over the Samsung?
Only if Dolby Vision and Dolby Atmos matter to you. Otherwise the Samsung's extra brightness and gaming headroom make it the stronger all-round pick.
Which has better sound?
The LG B5. It has Dolby Atmos and a 20W 2.0 system. The Samsung uses object-tracking sound but lacks Atmos, so a soundbar helps either set.
Which lasts longer?
Neither has a clear edge. OLED panels from both brands age similarly, and owners of both report solid build. The LG's higher owner rating is offset by some reports of connectivity and reliability issues.
