The LG B2 is a more versatile choice, offering significantly better gaming performance due to its higher refresh rate, and it also performs better in bright rooms compared to the LG A1. However, if you prioritize watching movies in dark rooms and are looking to pay less, the LG A1 could serve you well as it offers excellent picture quality and dark room performance. Both TVs have similar sound quality and support major HDR formats, but if having the latest model with improved features for a broader range of content is important, the LG B2 is the superior option.

Tom's guide

Nick Pino | March 2023
"The LG B2 OLED pairs lush, saturated colors and perfect contrast with a 120Hz screen, HDMI 2.1 ports and a great smart TV platform. The LG B2 OLED is an ideal alternative to the LG C2 OLED for folks who want a taste of OLED life without the sticker price that usually comes with it. The LG B2 OLED does a lot right in terms of performance, color saturation is wonderful and contrast is second-to-none. Not only did color saturation and off-axis viewing impress me, harder to quantify specs like motion processing and upscaling really blew me away as well."
