Stunning Picture Quality Powered by OLED Evo
The heart of the LG OLED Evo AI C5 is its self-lit OLED evo panel. Every one of the more than 8.3 million pixels produces its own light, delivering true infinite contrast and perfect black levels that LCD and Mini-LED TVs simply cannot match. Colors stay rich and natural, with excellent coverage of the DCI-P3 color space.
LG’s Brightness Booster helps the C5 reach peak brightness levels around 1,000–1,200 nits in HDR highlights, making it more capable in brighter rooms than earlier mid-range OLEDs. The “Bright Room Ready” anti-glare treatment further reduces reflections. Whether you’re watching movies in Filmmaker Mode, streaming Dolby Vision content, or viewing sports, the image stays sharp, detailed, and immersive.
Alpha 9 AI Processor Gen 8 and Smart Features
The α9 AI Processor 4K Gen 8 is the real upgrade over previous C-series models. It drives AI Super Upscaling that intelligently enhances lower-resolution content so it looks closer to native 4K. AI Picture Pro analyzes scenes in real time and optimizes contrast, color, and detail. AI Sound Pro creates a wider, more immersive soundstage from the built-in 2.2-channel 40W speakers, with virtual surround effects that work surprisingly well for everyday viewing.
The TV runs webOS 25, which feels responsive and offers a clean interface packed with major streaming apps. You get Apple AirPlay, Google Cast, built-in Alexa, and ThinQ voice control. AI Concierge and personalized profile features learn your preferences over time and suggest content or adjust settings automatically. Software support via webOS Re:New keeps the platform relevant for years.
Built for Gamers
Gamers will feel right at home. The C5 offers a native 120 Hz panel with Variable Refresh Rate (VRR) support up to 144 Hz. It is NVIDIA G-Sync Compatible and AMD FreeSync Premium certified. All four HDMI ports are full-bandwidth HDMI 2.1, supporting 4K/120 Hz and low input lag (often under 10–13 ms in game mode). Response time is an impressive 0.1 ms, eliminating motion blur. Game Optimizer and the on-screen Game Dashboard give quick access to settings, making console and PC gaming smooth and responsive.
