If you have a tight budget, the LG B2 OLED is significantly less expensive and offers excellent gaming performance and a very good dark room viewing experience. However, its performance in bright rooms isn't as strong. On the other hand, the Sony A90J OLED is pricier but delivers slightly better overall picture quality and sports viewing experience. It also has great sound quality thanks to its built-in speakers. Nevertheless, like the LG B2, it may not be the best choice for very bright rooms. It also has robust build quality and a higher quality control standard. Give Feedback

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."

"In every meaningful department – motion control, contrast, edge definition, detail levels, you name it the A90J puts in a memorably accomplished shift. In fact, the Sony proves outstanding at handling on-screen motion of any and every kind. By the standards of television audio systems, the A90J is a notably punchy and genuinely dynamic performer."
