The LG 77" Class C5 Series OLED evo (model OLED77C5PUA) is a 2025 4K smart TV with a 77.4-inch viewable screen. Its self-lit OLED pixels can turn completely off, which gives an infinite contrast ratio with no light bloom. The OLED evo panel uses Brightness Booster technology across its 8.3 million pixels for better visibility in bright rooms.
The α9 AI Processor Gen8 powers AI Picture Pro and AI Super Upscaling. It identifies the genre of the content, adds texture detail, smooths color gradients and reduces compression artifacts in lower-quality sources. The TV supports Dolby Vision and Dolby Atmos, and FILMMAKER MODE turns off frame interpolation and edge sharpening.
For gaming, the TV has a 0.1ms response time and a native 120Hz refresh rate. It supports NVIDIA G-SYNC Compatible, AMD FreeSync and Variable Refresh Rate. The webOS 25 home screen gives recommendations based on your streaming habits across apps such as Netflix, Disney+ and Max, and includes over 300 free LG Channels. The included LG Magic Remote lets you point, click and gesture to navigate.
