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

The Samsung S90H is the better pick for gamers and bright rooms: its 165Hz panel, glare-free coating and 40W 2.1 speakers beat the LG B5 on motion, reflection handling and built-in sound. The LG B5 is the stronger choice for movie lovers who want Dolby Vision and Dolby Atmos, and it costs less. Both are 65-inch OLEDs with excellent picture quality, but the Samsung is more future-proof for high-frame-rate gaming, while the LG offers better format support for films.

  • Choose the Samsung S90H if you play fast-paced games, watch in a bright room, or want the best built-in audio and a glare-free screen.
  • Choose the LG B5 if you want Dolby Vision and Dolby Atmos for movies, prefer webOS, and want to spend less on a 65-inch OLED.

Questions and answers

Which is better for gaming, the Samsung S90H or LG B5?
The Samsung S90H is better for gaming thanks to its 165Hz refresh rate, which gives smoother motion than the LG B5's 120Hz panel. Both support VRR and ALLM, but the Samsung's higher frame rate suits fast-paced games better.
Which has better picture quality?
Both use OLED panels with perfect blacks and wide viewing angles, so picture quality is close. The Samsung adds a glare-free coating that helps in bright rooms, while the LG supports Dolby Vision, which can improve HDR movies.
Does the LG B5 support Dolby Vision and Dolby Atmos?
Yes, the LG B5 supports both Dolby Vision and Dolby Atmos. The Samsung S90H does not support Dolby Vision.
Which TV has better built-in sound?
The Samsung S90H has a 2.1-channel 40W system with object tracking sound, while the LG B5 has a 2.0-channel 20W system. The Samsung should sound fuller and more immersive without a soundbar.
Is the Samsung S90H worth stepping up to over the LG B5?
If you play high-frame-rate games or watch in a bright room, the Samsung's 165Hz panel and glare-free screen are worth the extra cost. If you mainly watch movies and want Dolby Vision, the LG B5 is the better value.
