LG B6 48" OLED TV vs Samsung S90D OLED 4K Smart TV

Both are 48-inch OLEDs with 4 HDMI 2.1 ports and 120Hz-plus gaming, so the split comes down to priorities. The LG B6 runs webOS with a Magic Remote, supports Dolby Vision and FILMMAKER MODE, and weighs noticeably less. The Samsung S90D pushes higher refresh (up to 144Hz), adds an anti-reflection screen and Object Tracking Sound Lite, and works with both Alexa and Google Assistant. Buy the LG for Dolby Vision content and the simpler remote-driven interface; buy the Samsung for a brighter, more reflective-resistant panel and faster gaming refresh.

  • Choose the LG B6 if you watch a lot of Dolby Vision movies and shows and want the Magic Remote and webOS.
  • Choose the Samsung S90D if glare in your room is a problem or you want 144Hz gaming and both Alexa and Google Assistant.

What reviewers say

LG B6 48" OLED TV

  • 4.6 / 5120 ratings

Owners of LG's recent B-series OLEDs generally praise the picture, especially black levels and contrast in dark rooms, and find webOS and the Magic Remote easy to live with. Common complaints are peak brightness in bright rooms and the premium over LCD sets of the same size.

What people mention
  • Picture qualityPraisedOwners say OLED blacks and contrast make dark scenes look far better than on LCD sets.
  • BrightnessCriticisedReviewers note the panel cannot match bright LCDs in a sunlit room.
  • GamingPraisedThe 120 Hz panel and low input lag are well received by console players.
  • Smart platformPraisedwebOS and the Magic Remote are described as quick and easy to use.

Questions and answers

Which is better for a bright living room?
The Samsung S90D. Its anti-reflection screen cuts glare from windows and lamps, where the LG B6 uses a standard OLED panel that can look washed out in strong light.
Which is better for movies?
The LG B6, mainly because it supports Dolby Vision, which many streaming films and shows are mastered in. The Samsung handles HDR10 and HDR10+ but not Dolby Vision.
Which is better for gaming?
The Samsung S90D edges ahead with up to 144Hz refresh. The LG B6 matches it on HDMI 2.1 ports and adds G-Sync, so PC gamers with Nvidia cards may prefer the LG.
Is the Samsung worth stepping up to over the LG?
If glare or 144Hz gaming matters to you, yes. If you mostly watch Dolby Vision movies and want the Magic Remote, the LG covers that without the extra weight.
Which lasts longer?
Both use OLED panels with similar lifespans, and neither brand publishes a rated hour count. The LG adds OLED Care settings that help reduce burn-in risk; the Samsung's anti-reflection layer is the main long-term wear point to watch.
