The LG B6 77" OLED TV makes it easier to see what's really going on in every scene. Its Certified Perfect Black OLED display uses self-lit pixels to create deep blacks and sharp highlights, so details don't disappear into the shadows. The α8 AI Processor 4K Gen3 works in real time to refine picture and sound, so everything looks cleaner and more balanced. Plus, older films and shows are given a refresh with AI Super Upscaling. It sharpens lower-resolution content to add detail while boosting audio for clear dialogue. And if you're firing up your console, a 120 Hz refresh rate and 0.1 ms response time keep gameplay fast, smooth and responsive.
