Overview

The LG OLED55C3PUA represents the 2023 iteration of LG's acclaimed C-Series OLED lineup, delivering a 55-inch 4K display powered by the a9 AI Processor Gen6. This processor is engineered exclusively for LG OLED panels and uses AI-assisted deep learning to analyze on-screen content in real time, automatically optimizing picture and sound settings for whatever you are watching. The OLED evo panel with Brightness Booster technology produces self-lit pixels that can turn completely off for true blacks and infinite contrast, while also pushing higher peak brightness than previous generations — a meaningful improvement for HDR content and daytime viewing in well-lit rooms.

On the entertainment and gaming front, the C3 is loaded with features that justify its position as a premium all-rounder. Dolby Vision HDR and Dolby Atmos audio deliver a cinematic experience, while FILMMAKER MODE preserves the director's intended color grading and motion settings. For gamers, the native 120Hz refresh rate, 0.1ms response time, NVIDIA G-Sync compatibility, AMD FreeSync Premium, and VRR support across all four HDMI 2.1 ports make this TV one of the most capable gaming displays available. The LG Game Dashboard and Game Optimizer consolidate gaming settings into a single interface for quick adjustments. Running webOS 23, the C3 offers streamlined content discovery with Quick Cards, access to over 300 free LG Channels, and Alexa built in for hands-free voice control.
