LG 77-Inch OLED Evo AI 4K TV with Hyper Radiant Colour and 165 Hz Gaming

A brighter, richer OLED panel:

The OLED77C64LA is built around LG's new Primary RGB Tandem panel, which underpins the Hyper Radiant Colour Technology and delivers peak brightness up to 3.2 times higher than conventional OLED. Brightness Booster Pro and Pixel Dimming work together to maintain deep blacks and vivid colour whether the room is bright or dark.

Alpha 11 AI Processor 4K Gen3:

The Dual AI Engine inside the Alpha 11 AI Processor 4K Gen3 handles AI Object Remastering Ultra, Dynamic Tone Mapping Ultra, and AI Genre Selection in real time. The processor also drives Alpha 11 AI Sound Pro, producing a Virtual 11.1.2 Up-mix from the built-in 2.2-channel, 40 W speaker system with full Dolby Atmos support.

Gaming-ready at 165 Hz:

All four HDMI 2.1 ports support 4K at up to 165 Hz with VRR, ALLM, and eARC, backed by an Intertek-certified response time of less than 0.1 ms (Gray to Gray). G-Sync Compatible, FreeSync Compatible, HGiG Mode, and Dolby Vision for Gaming at 4K 120 Hz are all included, and VESA ClearMR 10000 certification confirms class-leading motion blur performance.

webOS 26 with multi-AI integration:

The AVForums Editor's Choice smart TV platform for eight consecutive years, webOS 26 now includes Google Gemini, Microsoft Copilot, and an AI Chatbot alongside AI Voice ID, AI Concierge, and Hands-free Voice Control. LG Shield provides seven layers of security across hardware and software, and the webOS Re:New Program delivers free OS upgrades for up to five years.

Certifications and awards:

The C6 holds UL "Perfect Black" certification for infinite contrast, Intertek "Perfect Colour" certification across 125 colour patterns at 100% DCI-P3 colour fidelity, Eyesafe RPF 40 certification for reduced blue light, and a CES Innovation Awards 2026 Honoree distinction for its LG Shield-applied TV OS platform.

Setup and Care

Getting started:

The AI Magic Remote pairs automatically on first power-up. The webOS 26 setup wizard guides you through Wi-Fi connection, account sign-in, and preferred AI assistant selection in a straightforward sequence.

Wall mounting:

The VESA mounting pattern is 300 x 200 mm. A compatible wall bracket is required and is purchased separately. LG recommends two people for installation given the 23.50 kg panel weight.

Picture calibration:

The AI Picture Wizard provides guided on-screen calibration using the built-in camera (USB Camera Compatible). FILMMAKER MODE™ disables motion smoothing and applies director-intended colour settings automatically when supported content is detected.

Screen care:

Wipe the screen gently with a soft, dry microfibre cloth. Avoid applying liquid directly to the panel. LG Quad Protection covers lightning, humidity, surge, and LG Shield software-level security from day one.
