The panel’s self-lit pixel technology allows each individual pixel to turn on and off independently, achieving infinite contrast and perfect black levels. Whether you’re watching a dark thriller or vibrant nature documentary, every frame is rendered with 100% color fidelity and 100% color volume, ensuring that colors are both rich and accurate across different brightness levels. This is OLED at its most precise and cinematic.
Dolby Vision, FILMMAKER Mode, and HDR: A Home Cinema Experience
Experience cinema the way it was meant to be seen with the combination of Dolby Vision and FILMMAKER Mode™. Dolby Vision dynamically adjusts contrast and brightness scene by scene, while FILMMAKER Mode disables motion smoothing and sharpening for a purist picture quality that aligns with the director’s vision. With added support for HDR10 and HLG, this TV covers every major HDR format.

Sound is just as important as visuals, and the LG B4 doesn’t compromise. Powered by α8 AI Sound Pro, the TV performs room-aware tuning via AI Acoustic Calibration to deliver immersive audio tailored to your environment.
