LG Electronics OLED77C9PUB 77″ 4K UHD OLED Smart TV with AI ThinQ
Perfect black brings out the darkest details.
Perfect black and infinite contrast bring out shadow detail in the darkest scenes. That’s the power of 8.3 million individually lit pixels in LG OLED TVs.
The brains to make everything look more real.
Images, action and color are brought to new life to instantly enhance picture quality through LG’s best 4K processor including 4-step noise reduction — empowered by AI at its core.
The world’s most intelligent TVs.
LG AI TVs are the first with the Google Assistant* and Alexa** built in, using LG ThinQ AI technology to become the center for your smart home.
Every viewing is like a gallery showing.
There’s thin. Then there’s OLED thin. LG OLED TV’s individually lit pixels require no backlight — a thing of beauty on the wall or on its premium stand.
Transform your TV into an entertainment powerhouse.
Advanced image and sound technologies inspired by the cinema optimize picture and sound for a spectacular, more lifelike experience in every scene — it’s ultravivid picture and powerful, moving audio that seems to flow all around you.
