Product Overview
The LG OLED77C5 77 Inch OLED 4K Smart TV sits in LG’s premium OLED lineup and is built around self-lit pixel technology, where each pixel produces its own light. This allows the display to achieve very deep blacks and extremely high contrast without relying on a backlight.
Powered by the α9 AI Processor 4K Gen8 and LG’s latest webOS platform, the TV focuses on high-end picture refinement, smooth motion handling, and advanced gaming performance. The 77-inch size is especially suited for home theater-style setups where immersive viewing is a priority rather than compact space usage.
