Overview

The LG OLED evo C4 Series in the 77-inch configuration represents LG's mainstream flagship OLED offering for 2024. At its core are over 8 million self-lit OLED pixels capable of switching on and off independently, which produces the infinite contrast ratio that has made OLED the display technology of choice for home theater enthusiasts. LG's Brightness Booster technology works at the individual pixel level to improve luminance, while the α9 AI Processor Gen7 handles real-time content analysis and upscaling — automatically detecting whether you're watching sports, film, or animation and adjusting processing accordingly. Dolby Vision HDR and Dolby Atmos audio support come standard, and the inclusion of Filmmaker Mode ensures that movies are displayed with the creator's intended color science and motion handling.

For gamers, the C4 is particularly compelling. It supports a 144Hz refresh rate with a 0.1ms response time, compatibility with NVIDIA G-Sync, AMD FreeSync Premium, and variable refresh rate technology. All four HDMI ports are full-bandwidth HDMI 2.1, eliminating the common frustration of having to choose which device gets the premium connection. The built-in Game Dashboard and Game Optimizer give users quick access to input lag, frame rate, and HDR settings without leaving gameplay. On the smart TV side, webOS provides access to all major streaming apps, and LG's Re:New Program commits to five years of software updates, addressing the common concern of smart TV platforms becoming outdated before the display hardware wears out.
