LG B5 OLED TV vs Samsung OLED S90F 4K Smart TV

Both are 4K OLEDs with 120Hz-plus panels and four HDMI 2.1 ports, so picture quality is close. The Samsung S90F edges ahead for bright rooms and gamers: its Glare-Free coating fights reflections and its panel runs to 144Hz with VRR up to 165Hz. The LG B5 is the simpler, lighter set with Dolby Vision and Dolby Atmos, which the Samsung lacks. Buy the Samsung if your room is bright or you game hard; buy the LG if you want Dolby Vision films and a lighter, easier wall mount.

  • Choose the LG B5 if you watch a lot of Dolby Vision movies, want Dolby Atmos, and prefer a lighter TV that is easier to wall-mount.
  • Choose the Samsung S90F if your room has windows or lamps facing the screen, or if you want the fastest panel for console and PC gaming.

What reviewers say

LG B5 OLED TV

  • 4.7 / 54,200 ratings

With 4.7 out of 5 from about 4,200 ratings, owners are largely happy with the B5's picture and gaming features. Most praise comes from people stepping up from LED TVs. Complaints center on brightness in bright rooms and the step down from the C series.

What people mention
  • Picture qualityPraisedOwners say blacks are deep and colors look rich, especially in dim rooms.
  • BrightnessCriticisedReviewers say it struggles in bright, sunlit rooms compared with brighter OLEDs.
  • GamingPraisedBuyers like the 120Hz panel with VRR for consoles and PC.
  • ProcessorMixedSome say the Alpha 8 chip is fine, others notice weaker upscaling than the C series.

Samsung OLED S90F 4K Smart TV

Reviewers rate the S90F highly for its glare-free OLED picture, deep blacks and strong gaming features. Many call it one of the better-value premium OLEDs of 2025, though some miss Dolby Vision and note that peak brightness is lower than top-tier QD-OLEDs.

What people mention
  • Glare handlingPraisedOwners say the glare-free coating keeps windows and lamps from washing out the picture.
  • BrightnessMixedReviewers find it bright enough for most rooms but dimmer than top QD-OLEDs in direct light.
  • GamingPraisedPlayers report low lag, smooth 144 Hz motion and working VRR across the four HDMI 2.1 ports.
  • Dolby VisionCriticisedSome reviewers mark it down for supporting HDR10+ but not Dolby Vision.
Reviews
  • You can get an LG B5 OLED for less than $900

Questions and answers

Which is better for a bright living room?
The Samsung S90F. Its Glare-Free coating cuts reflections from windows and lamps, where the LG B5's glossy panel shows them more.
Which is better for gaming?
The Samsung. Its 144Hz panel and VRR up to 165Hz beat the LG's 120Hz, though both have four HDMI 2.1 ports and low latency modes.
Does the LG B5 have Dolby Vision and the Samsung not?
Yes. The LG B5 supports Dolby Vision, HDR10 and HLG. The Samsung S90F uses OLED HDR+ and does not support Dolby Vision.
Which lasts longer?
Both use OLED panels with similar lifespans. The Samsung states a 24-month warranty, which is longer coverage than LG's standard term.
Is the Samsung worth stepping up to over the LG?
If you game or watch in a bright room, yes. If you mainly watch Dolby Vision films and want a lighter TV, the LG B5 covers you.
Which is easier to wall-mount?
The LG B5. At 51.8 lb on the 77-inch it is far lighter than the Samsung's 92.6 lb, so it needs less heavy-duty hardware.
