Our Verdict
LG B1 OLED
LG A1 OLED
The LG B1 OLED is a higher-end TV than the LG A1 OLED, so it performs better overall. They deliver similar exceptional picture quality thanks to their OLED panels, and even though the B1 gets brighter, it's not a significant difference. The B1 uses a different screen finish, so it has better reflection handling. The main differences are with the gaming features because the B1 has a 120Hz panel with VRR support and HDMI 2.1 inputs, delivering a better gaming experience. The A1 is limited to a 60Hz panel with no VRR.
