Samsung S90H OLED 4K TV (65") vs LG B5 Series 65" OLED TV

The Samsung S90H is the stronger TV on paper: a 165Hz panel, glare-free coating, Wi-Fi 6E and a brighter, more gaming-focused feature set, and its 4.9 rating from 866 owners backs that up. The LG B5 is the entry rung of LG's OLED line, so it gives you the same perfect blacks and wide viewing angles with Dolby Vision and Dolby Atmos, but at a lower 120Hz and a dimmer, more reflective panel. Buy the Samsung for a bright room or serious gaming; buy the LG if Dolby Vision matters most and you watch in a dark room.

  • Choose the Samsung S90H if you game at high frame rates, watch in a bright room, or want the glare-free screen and the higher-rated set.
  • Choose the LG B5 if Dolby Vision and Dolby Atmos matter to you and you mostly watch movies in a darkened room.

Questions and answers

Which is better for gaming, the Samsung S90H or the LG B5?
The Samsung S90H. Its 165Hz panel and Motion Xcelerator beat the LG's 120Hz, and both support VRR and ALLM. The LG adds G-Sync compatibility, which matters mainly for PC players with Nvidia cards.
Does the LG B5 have Dolby Vision and the Samsung not?
Yes. The LG B5 supports Dolby Vision and Dolby Atmos; the Samsung S90H supports HDR10+ instead. On Dolby Vision titles the LG can look more controlled in highlights, while the Samsung's glare-free screen wins in bright rooms.
Which handles a bright living room better?
The Samsung S90H. Its glare-free coating suppresses reflections that the LG B5's glossy panel shows. If your room has big windows or daytime glare, that difference is visible every day.
Is the Samsung S90H worth stepping up to over the LG B5?
For gamers and bright-room viewers, yes: faster panel, better reflection handling, newer wireless and stronger sound. If you mostly watch Dolby Vision films in a dark room, the LG covers the essentials and you give up little.
Which has better built-in sound?
The Samsung S90H. It runs a 2.1-channel 40W system with object tracking sound; the LG B5 has a basic 2.0 setup that decodes Dolby Atmos but has less output. A soundbar helps either one.
Which is more reliable or better rated by owners?
The Samsung S90H rates higher, 4.9 from 866 ratings against 4.5 from 374 for the LG B5. Both are OLEDs, so both carry the usual risk of image retention from static logos and tickers.
