Overview

The LG OLED77G4WUA is the 77-inch flagship of LG's 2024 OLED evo G4 series, built around over 8 million self-lit OLED pixels that produce perfect blacks, infinite contrast, and 100% Color Volume across the entire brightness range. Brightness Booster Max technology pushes the panel's peak luminance beyond what previous OLED generations could achieve, bringing HDR highlights and sunlit scenes to life without sacrificing the deep blacks that define the OLED viewing experience. Dolby Vision and Filmmaker Mode ensure content is displayed with cinematic accuracy, while Dolby Atmos delivers immersive spatial audio through the built-in speaker system.

At the heart of the G4 is LG's α11 AI Processor, which powers AI Picture Pro for real-time scene optimization, AI Super Upscaling for sharpening lower-resolution content, and a Multi View mode that splits the screen into up to four independent windows. For gamers, NVIDIA G-Sync and AMD FreeSync compatibility paired with a native 120Hz refresh rate and dedicated Game Mode deliver responsive, tear-free performance. The TV's signature One Wall Design allows the ultra-slim panel to mount virtually flush against any wall, and when not in active use, it can display artwork and photography to blend into your living space. LG's webOS 24 platform provides access to all major streaming apps, and the included Magic Remote with built-in Alexa adds voice control and NFC connectivity.
