Our Verdict
LG B3 OLED
LG B4 OLED
The LG B4 OLED is better than the LG B3 OLED. The B4 has HDMI 2.1 bandwidth on all four ports, whereas the B3 only as it on two, so the B4 is more versatile if you have multiple high-bandwidth devices. The B4 also gets brighter overall, so highlights stand out more in HDR content, and it can overcome more glare in a bright room while watching SDR content. On top of that, the B4 has better HDR gradient handling for less banding.
