LG B5 OLED vs Samsung S90H 65" OLED 4K TV

The LG B5 is the safer pick for most shoppers: a well-reviewed entry OLED with four HDMI 2.1 ports, Dolby Vision and Dolby Atmos, and a 120Hz panel that gamers and movie watchers both praise. The Samsung S90H counters with a brighter, glare-free QD-OLED panel, a 165Hz refresh rate, HDR10+ and Wi-Fi 6E, plus a much deeper smart feature set. Owners report the B5's weak spots are Wi-Fi dropouts and sluggish apps; the Samsung is the stronger set on paper and for bright rooms, but it carries more features to learn and no Dolby Vision.

  • Choose the LG B5 if you want a proven OLED with Dolby Vision, Dolby Atmos and four HDMI 2.1 ports at the entry end of OLED.
  • Choose the Samsung S90H if you watch in a bright room, game at high frame rates, or want HDR10+, Wi-Fi 6E and the fullest smart TV feature set.

Questions and answers

Which is better for gaming?
The Samsung S90H. It runs at 165Hz, supports VRR, FreeSync Premium Pro and G-Sync, and adds a Game Bar and cloud gaming. The LG B5 is still a strong gaming set with 120Hz and four HDMI 2.1 ports.
Which handles bright rooms better?
The Samsung S90H, whose Glare Free coating and Contrast Booster are built for daylight viewing. The LG B5 is dimmer on paper, though reviewers say it holds up well in practice.
Does the Samsung have Dolby Vision?
No. It supports HDR10+ instead. The LG B5 supports Dolby Vision, which matters if your streaming library leans on it.
Which lasts longer?
Neither has a documented edge. OLED panels from both brands are rated for years of normal use, and the B5 has the longer public track record of owner reports.
Is the Samsung worth stepping up to?
Yes if you want a brighter panel, 165Hz gaming and Wi-Fi 6E. If Dolby Vision and a simpler, proven set matter more, the LG B5 is the better fit.
Which is easier to live with?
The LG B5. webOS is simpler and reviewers call it easy to use. The Samsung packs more apps and AI features, which some owners find busy.
