Overview

The LG 55-inch OLED B4 Series represents LG's entry point into its 2024 OLED television lineup, bringing the core benefits of self-lit pixel technology to a more accessible price bracket. Each of the over 8 million pixels produces its own light independently, which means the TV can turn pixels completely off for true blacks and infinite contrast — a fundamental advantage over LED and mini-LED displays. The panel delivers 100% Color Volume and 100% Color Fidelity, ensuring colors remain accurate and vivid across the full brightness range. With Dolby Vision HDR and Filmmaker Mode, movies and shows are presented with the color grading and contrast their creators intended, while Dolby Atmos support adds spatial audio depth from the built-in speakers.

Under the hood, the α8 AI Processor 4K powers the B4's automatic content optimization through AI Picture Pro, which identifies whether you're watching sports, cinema, or gaming content and adjusts settings in real time. For gamers, this TV is particularly well-equipped: four HDMI 2.1 inputs support 4K at 120Hz, and the 0.1ms response time combined with NVIDIA G-Sync, AMD FreeSync Premium, and VRR support ensures smooth, tear-free gameplay. The Multi View feature lets you split the screen into two views simultaneously. Running webOS 24 with over 300 free LG Channels, the smart TV platform is intuitive and well-stocked with streaming apps, and the five-year webOS Re:New Program guarantees continued software support. At 48.3 x 30.4 x 9.3 inches with the stand, the B4 fits comfortably in most living rooms and entertainment centers.
