LG 77G4 77" Class LG OLED evo G4 4K Smart TV

The LG 77G4 77" Class LG OLED evo G4 4K Smart TV brings cinema-quality picture and sound into the living room with self-lit OLED technology. Each of the more than 8.3 million pixels lights independently, delivering perfect blacks, rich colors, and impressive contrast without the blooming often seen on other displays. Powered by the advanced Alpha 11 AI Processor, this 2024 model uses AI Picture Pro and AI Super Upscaling to keep images smooth and detailed, whether you are watching native 4K content or older lower-resolution shows.

Designed for both movie nights and serious gaming, the set supports Dolby Vision, Dolby Atmos, and FILMMAKER MODE for accurate, director-intended viewing. Gamers get a native 120 Hz panel that reaches up to 144 Hz with VRR, plus NVIDIA G-Sync, AMD FreeSync Premium, and a response time under 0.1 ms. Brightness Booster Max technology pushes each pixel harder for brighter highlights while preserving deep blacks. With webOS 24, built-in streaming apps, LG Channels, and up to five years of software updates, the TV stays current long after purchase. A five-year panel warranty and OLED Care features add extra peace of mind for years of reliable use.
