If your budget allows for a higher investment and you appreciate nuanced picture quality, the Sony A90K stands out, particularly in quality control and as a monitor. It also has better reflections handling, beneficial in brighter rooms. However, the LG B2, while more affordable, still provides excellent picture quality and better performance in dark rooms. Both offer exceptional contrast and color, with the LG B2 having a slight edge in HDR brightness. If gaming is a priority, both TVs are comparable, but the LG B2 has slightly more gaming features. For sports and general viewing, either TV performs well. Remember, the Sony A90K has a smaller screen at 48 inches, while the LG B2 offers a 55-inch screen, which could influence your decision based on room size and viewing distance. 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."
