    A man sits in front of a sound board watching a film on the LG OLED B4 with Dolby Vision™, Dolby Atmos® and FILMMAKER MODE™ logos.

    LG's flagship OLED technology creates an incredible watching experience and stellar picture quality illuminated with over 8 million self-lit pixels. Take in rich and accurate colors from the brightest to darkest parts of the scene thanks to 100% Color Volume1 and with 100% Color Fidelity.2

    Every LG OLED comes loaded with Dolby Vision™ for extraordinary color, contrast and brightness, plus Dolby Atmos®3 for sound you can feel all around you. Land in the center of the action with FILMMAKER MODE™ to see films just as the director intended.

    The α8 AI Processor 4K with AI Picture Pro automatically adjusts the ideal settings and fine-tunes the picture based on your content. Plus, with Multi View, you can split your screen into two unique views so you can watch even more than before.4

    Experience crisp, smooth imagery from a 0.1ms response time and up to 120Hz refresh rate5 for blazingly fast gaming without any blurring or tearing, plus NVIDIA G-Sync, AMD FreeSync Premium and VRR for improved quality. Control all your devices from four HDMI 2.1 inputs with the LG Game Dashboard and Game Optimizer.6
