The LG B2 OLED TV is a higher-priced option and performs better overall, especially for gaming, movies, and darker room settings due to its superior contrast and viewing angles. This makes it a good choice if these are your priorities and you're willing to invest more. The Sony X77L LCD TV is more affordable, but it may not perform as well in darker environments and offers a less immersive experience for gaming and movie-watching. If you watch TV in a brighter room, the Sony is acceptable but for sunny spaces or high-quality content viewing, the LG B2 would be more satisfying. 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."

"For an entry-level model, Sony’s X77L is a decent 4K TV. It’s color reproduction, along with crisp and clean picture images revealed plenty of detail and clarity thanks in part to Sony’s excellent video processing."
