Samsung S90H OLED TV vs LG B5 Series OLED TV

Both are 55-inch 4K OLEDs with per-pixel contrast, but they aim at different buyers. The Samsung S90H is the stronger pick for gaming and bright rooms: a 165Hz panel, VRR to 4K 165Hz, FreeSync Premium Pro and G-Sync certification, plus a glare-reducing coating. The LG B5 is the safer mainstream TV: 120Hz, webOS with all the major apps, and the B-series reputation for solid picture quality at the entry end of LG's OLED line. Owners of both lines praise the blacks; the Samsung's anti-glare layer and higher refresh are the real separators.

  • Choose the Samsung S90H if you game on PC or console at high frame rates, watch in a room with windows or lamps, or want G-Sync and FreeSync certification on one panel.
  • Choose the LG B5 if you want a straightforward smart TV for streaming and movies, value webOS and its app lineup, and do not need refresh rates above 120Hz.

Prices

  • Samsung S90H OLED TV: $1,047.99 at eBay (last seen Nov 9)
  • LG B5 Series OLED TV: $799.99 at Bstock (last seen Nov 9)
  • Difference: the LG B5 Series OLED TV is $248.00 cheaper than the Samsung S90H OLED TV at the latest prices (Nov 9)

Questions and answers

Which is better for gaming, the Samsung S90H or the LG B5?
The Samsung S90H. Its 165Hz panel, VRR to 4K 165Hz and G-Sync plus FreeSync Premium Pro certification give it more headroom for high-frame-rate PC and console play. The B5 tops out at 120Hz.
Which handles a bright room better?
The Samsung S90H, because of its Glare-Free coating. The B5 uses a standard glossy OLED finish, so lamps and windows show up more in dark scenes.
Does the LG B5 support Dolby Vision?
Yes. The B5 supports Dolby Vision and HDR10. The Samsung S90H uses HDR10+ instead and does not list Dolby Vision.
Which smart TV platform is better, Tizen or webOS?
They are close. webOS on the B5 has a broad app lineup and a simple launcher. Tizen on the S90H adds SmartThings Hub and Knox security, which matter more if you are building a connected home.
Is the Samsung S90H worth stepping up to over the B5?
If you game at high frame rates or watch in a bright room, yes. For streaming movies and shows at 120Hz, the B5 covers the basics and adds Dolby Vision.
Which lasts longer?
Both are OLED panels with similar care needs: avoid static logos for long stretches and use the built-in screen care features. Neither brand publishes a lifespan figure that separates them clearly.
