LG B5 OLED TV vs Samsung 42” S90H OLED 4K Smart TV

The Samsung S90H is the stronger pick for most people: a glare-free OLED panel, a 165Hz refresh rate and a newer processor beat the LG B5 on brightness handling and gaming headroom. The LG B5 is the better fit if you want a larger screen, Dolby Vision and Dolby Atmos, which the S90H lacks. Both are OLED with deep blacks and wide viewing angles, and owners of both praise picture quality; S90H owners more often mention glare handling, while B5 buyers get the more complete HDR format support.

  • Choose the LG B5 if you want Dolby Vision and Dolby Atmos support and a bigger screen for movies and sports.
  • Choose the Samsung S90H if you game at high frame rates or watch in a bright room and want the glare-free panel.

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 42” S90H OLED 4K Smart TV

  • 4.9 / 5870 ratings

The combination of OLED contrast and the new anti-glare coating is frequently cited as a major improvement over previous generations. Buyers praise ink-like blacks, even screen uniformity and smooth gaming motion, and call setup and Tizen navigation easy. Complaints center on tuning the picture and on dialogue clarity.

What people mention
  • ReflectionsPraisedThe Glare Free technology is highly effective at neutralizing ambient light in bright environments.
  • GamingPraisedThe 165Hz refresh rate and Ultimate Gaming Pack make it a top choice for PC and console gamers.
  • Sound qualityCriticisedThe 20W speakers are described as thin, often requiring an external soundbar for a full experience.
Reviews
  • You can get an LG B5 OLED for less than $900

Questions and answers

Which is better for gaming, the LG B5 or the Samsung S90H?
The S90H has the edge with a 165Hz refresh rate and the Ultimate Gaming Pack. The B5 still covers the basics well with 120Hz, VRR, G-Sync and FreeSync Premium on four HDMI 2.1 ports.
Does the Samsung S90H support Dolby Vision?
No. It handles HDR10, HDR10+ and HLG. The LG B5 supports Dolby Vision, so Dolby Vision discs and streams look their best there.
Which handles a bright room better?
The S90H. Its Glare Free coating reduces reflections, and owners say it works well in daylight. The B5 uses a standard OLED finish that can show reflections.
Is the LG B5 worth stepping up to over the S90H?
Step up to the B5 if you want Dolby Vision, Dolby Atmos or a much larger screen. If you mostly game or watch in a bright room, the S90H is the better fit.
Which lasts longer?
Both are OLED sets with similar panel lifespans, and neither brand publishes a firm figure. The S90H carries a one-year manufacturer warranty; check the B5's warranty terms at the store you buy from.
