LG OLED B6 65" 4K Smart TV vs LG B3 Series OLED TV

Both are 65-inch LG OLEDs with 120Hz panels and four HDMI 2.1 ports, so gaming and movie basics are close. The B6 is the newer set: brighter Alpha 8 Gen3 processing, Dolby Vision and Dolby Atmos support, webOS 24 and Wi-Fi 5 with Bluetooth 5.3. The B3 is the older, well-proven model with a much larger owner base and higher owner rating. Buy the B6 for the newer processing and software; buy the B3 if you want the safer, widely reviewed set and don't need the latest chip.

  • Choose the LG B6 if you want the newer processor, webOS 24 and Dolby Vision and Atmos support in a 65-inch OLED.
  • Choose the LG B3 if you want a proven OLED with a long track record and a large base of owner reviews.

Questions and answers

Which is better for gaming, the B6 or the B3?
The B6. Both run 120Hz with HDMI 2.1 and VRR, but the B6 adds G-Sync, FreeSync Premium and a Game Optimizer dashboard.
Does the B3 support Dolby Vision?
Dolby Vision is not listed for the B3. The B6 lists Dolby Vision, HDR10 and HLG, so it handles more HDR sources.
Is the B6 worth stepping up to over the B3?
If you want the newer processor, webOS 24 and Dolby Vision and Atmos, yes. If you mainly watch SDR and standard HDR10 content, the B3 covers the basics.
Which has better voice assistant support?
The B3 lists Google Assistant, Amazon Alexa and Siri. The B6 listing does not name third-party assistants, so check before relying on them.
Which is more reliable?
The B3 has far more owner ratings and a higher average, which is the better evidence base. The B6 is too new to judge long-term.
Do both have four HDMI 2.1 ports?
The B6 lists four HDMI 2.1 inputs. The B3 lists HDMI 2.1 but not the port count, so confirm the number before buying.
