The LG OLED77G56LA is a 77 inch OLED evo AI set from LG’s 2025 line-up. Each pixel makes its own light, so black areas of the picture are genuinely switched off rather than dimmed. The screen is driven by the a11 AI Processor Gen2, and webOS is built in with a voice recognition remote in the box.

Split comparison of a night mountain scene, greyish on a non Perfect Black display and black with visible stars on a Perfect Black display, with a UL verification mark — The dark parts of a film stay dark even with lamps on or daylight in the room, so night scenes and closing credits do not turn grey.

Key Features

Black stays black with the lights on. Perfect Black is UL verified to hold black levels at or below 0.24 nit in rooms up to 500 lux.
Bright enough for a living room in daytime. Brightness Booster Ultimate uses the a11 Gen2 light emitting structure and lighting control for peak brightness three times that of the LG OLED B5, measured on a 10% window.
Older films and normal broadcast still look sharp. The a11 AI Processor Gen2 upscales lower resolution video to 4K pixel by pixel, which matters on a screen this wide.
Apps and menus respond quickly. Against the same year entry level a7 Gen8 chip, the a11 Gen2 runs 2.2x faster with 3.6x the graphics performance.
Talk to the TV instead of typing. The remote has a voice recognition button, so you can search by speaking rather than tapping letters on screen.
Sits almost flat against the wall. The panel is 24.8mm deep, 1712mm wide and 982mm tall.
