Designed for film lovers, gamers and anyone seeking premium home entertainment, this compact OLED TV delivers stunning visuals powered by LG's renowned self-lit OLED technology. With perfect blacks, infinite contrast, Dolby Vision HDR, Dolby Atmos audio and the powerful α9 AI Processor, the LG OLED42C66LB transforms everything you watch into a breathtaking viewing experience.

Ideal for living rooms, bedrooms, gaming setups and media spaces, the LG OLED42C66LB combines flagship OLED performance with a versatile 42-inch screen size that's perfect for both entertainment and next-generation gaming.

Self-Lit OLED evo 4K Display

Unlike conventional LED TVs, the LG OLED42C66LB uses millions of self-lit pixels that illuminate independently without the need for a backlight. This advanced OLED technology delivers exceptional picture precision, stunning colour accuracy and remarkable detail in every scene. The result is a truly cinematic 4K viewing experience with incredible realism and depth.

Perfect Black and Infinite Contrast

Experience the power of OLED's signature Perfect Black technology. Every pixel can switch on or off independently, allowing the LG OLED42C66LB to achieve true black levels and virtually infinite contrast. Dark scenes reveal hidden detail, while bright highlights stand out with exceptional intensity, creating a picture that looks remarkably lifelike.

α9 AI Processor Gen6

At the heart of the LG OLED42C66LB is the intelligent α9 AI Processor Gen6, engineered to optimise both picture and sound in real time. Using advanced deep-learning algorithms, the processor analyses content frame-by-frame to enhance sharpness, improve colour accuracy, boost contrast and deliver clearer, more immersive audio performance.

Dolby Vision HDR for Cinematic Picture Quality

Enjoy stunning HDR entertainment with support for Dolby Vision and other leading HDR formats. The LG OLED42C66LB dynamically optimises brightness, contrast and colour scene-by-scene, revealing greater detail in both bright and dark areas of the image. Movies, TV shows and games appear more realistic and engaging than ever before.

4K AI Upscaling

Not everything is filmed in 4K, but everything can look better. The LG OLED42C66LB features advanced 4K AI Upscaling technology that intelligently enhances lower-resolution content, improving texture, reducing noise and increasing detail to deliver a sharper, cleaner viewing experience.

Smart Entertainment with webOS

Access all your favourite content through LG's intuitive webOS Smart TV platform. The LG OLED42C66LB provides seamless access to popular streaming services including Netflix, Disney+, Prime Video, Apple TV+, YouTube and more. Personalised recommendations and fast navigation make finding your next favourite show simple and enjoyable.

Dolby Atmos Immersive Audio

Complementing the stunning OLED picture is Dolby Atmos audio technology. The LG OLED42C66LB creates a rich, multidimensional soundstage that enhances dialogue, effects and music, making movies, sports and games feel more immersive and engaging.

Built for Gaming

The LG OLED42C66LB is an outstanding choice for gamers.

Whether you're gaming on PlayStation 5, Xbox Series X or PC, this OLED TV is designed to keep up with the action.

Filmmaker Mode

Watch films exactly as directors intended with Filmmaker Mode. By disabling unnecessary motion smoothing and image processing effects, the LG OLED42C66LB preserves original frame rates, colours and aspect ratios for an authentic cinematic viewing experience.

Smart Connectivity and Voice Control

Take control using your voice with LG ThinQ AI and compatibility with supported voice assistants. Search for content, adjust settings, launch apps and manage compatible smart home devices using simple voice commands for a more convenient entertainment experience.
