Overview

The LG OLED55B4PUA brings LG's core OLED strengths — over 8 million self-lit pixels, infinite contrast ratio, and 100% color volume — to a 55-inch panel at a renewed price point. Each pixel produces its own light and switches off completely for true black, eliminating the backlight blooming and gray blacks common on LED-LCD panels. Dolby Vision HDR and Dolby Atmos audio are built in, and Filmmaker Mode lets you view movies with the director's original color grading and frame cadence intact. The α8 AI Processor 4K handles content recognition and automatic picture optimization, analyzing what you are watching — sports, cinema, animation, or games — and adjusting settings in real time without manual intervention.

For gaming, the B4 series checks every box current-generation consoles demand. All four HDMI 2.1 ports support 4K at 120Hz, and the panel delivers a 0.1ms response time with NVIDIA G-Sync, AMD FreeSync Premium, and variable refresh rate (VRR) support. LG's Game Optimizer and Game Dashboard provide quick access to input lag settings, black stabilizer, and frame rate counters without leaving the game. On the smart TV side, webOS 24 offers a clean interface with access to major streaming services and over 300 free LG Channels. As a renewed unit, this TV has been professionally inspected and tested to meet like-new standards, making it a compelling option for buyers who want OLED picture quality without paying full retail.
