Overview

The LG OLED83B4P brings the cinematic scale of an 83-inch display together with OLED's signature picture quality. Every pixel on the panel is self-emitting, which means it can shut off independently to produce perfect blacks and an essentially infinite contrast ratio. Colors are rendered with accuracy and richness across wide viewing angles, making this TV well-suited for large living rooms where multiple viewers may be watching from different positions. The Alpha 8 AI Processor Gen2 works behind the scenes to upscale lower-resolution content, optimize tone mapping for HDR material, and adjust audio output to match the content being played.

On the smart TV side, webOS provides a polished interface with access to all major streaming services and LG's own free channel lineup through LG Channels. Audio features include Clear Voice Pro, which isolates and enhances dialogue to keep conversations intelligible during action-heavy scenes, and LG Sound Sync for streamlined wireless pairing with compatible soundbars. The seamless design keeps bezels to a minimum, allowing the picture to dominate the viewing experience. For anyone seeking a large-format OLED that balances performance and value within LG's 2024 lineup, the B4 Series at 83 inches delivers a compelling combination of size, picture quality, and smart features.
