Bring home a more refined OLED experience with the LG OLED48C66LB OLED evo AI C6 4K Smart TV. Designed for those who want premium picture quality in a more compact size, this 48-inch model blends advanced AI processing, rich OLED contrast and next-gen Smart TV features into a sleek, modern design.

Compact Size, Flagship Performance

The OLED48C66LB is ideal for smaller living rooms, bedrooms or gaming setups where space is limited—but expectations aren’t. Despite its size, it carries the same advanced technology found in LG’s higher-end OLED range, delivering strong brightness, accurate colours and smooth motion.

OLED evo – Brighter, More Detailed Visuals

OLED technology is known for its self-illuminating pixels, allowing each pixel to switch on and off independently. This results in true blacks, excellent contrast and precise detail.

With OLED evo, brightness levels are improved further, helping highlights stand out more clearly while maintaining natural tones. The result is a picture that looks more lifelike, whether you're watching films, sports or everyday TV.

Alpha 11 AI Processor Gen 3 – Smarter Picture & Sound

Powered by LG’s most advanced processor, the Alpha 11 AI Processor Gen 3 enhances everything you watch in real time.

• Sharper image clarity with advanced AI upscaling
• More natural colours and improved depth
• Better motion handling for fast-paced scenes
• Enhanced sound processing for clearer dialogue

With a faster CPU and GPU compared to previous generations, performance feels noticeably smoother—both in picture processing and Smart TV navigation.

Dual AI Upscaling for Improved Content

Not everything you watch is filmed in 4K—but this TV works hard to make it look close. Dual AI Upscaling analyses content and enhances it intelligently, improving sharpness and reducing noise so HD and even SD content appears clearer on a 4K screen.

Cinematic Picture with Advanced HDR

Enjoy films the way they were meant to be seen with support for Dolby Vision HDR and Precision HDR processing.

• Improved brightness and contrast scene by scene
• More accurate colours and shadow detail
• Filmmaker Mode preserves original settings

Ambient Light Compensation adjusts the image based on your room lighting, so you still get a consistent viewing experience during the day or at night.

Native 120Hz Display for Smooth Motion

The 120Hz panel ensures smoother motion across sports, action films and gaming. Combined with OLED’s near-instant response time, motion blur is kept to a minimum, making fast scenes look clean and controlled.

Built for Serious Gaming

This LG OLED TV is designed with gamers in mind:

• Ultra-fast response time (under 0.1ms)
• HDMI 2.1 ports for high-bandwidth gaming
• Support for 4K 120Hz consoles and up to 4K 165Hz PC gaming
• Game Optimiser for quick access to settings

Compatibility with NVIDIA G-SYNC and AMD FreeSync Premium helps reduce screen tearing and stuttering, while Dolby Vision Gaming enhances visual detail in supported titles.

Cloud gaming is also supported via services like GeForce Now, allowing you to play without a console.

AI Sound Pro & Virtual Surround

Audio is enhanced using LG’s AI-powered sound technologies:

• AI Sound Pro adapts audio based on content
• Voice Remastering improves dialogue clarity
• Virtual 11.1.2 surround effect creates a wider soundstage

For an even richer experience, pairing with a compatible LG soundbar unlocks WOW Orchestra, allowing both TV and soundbar speakers to work together.

webOS 26 – Smarter, Faster, More Personal

The updated Smart TV platform offers a more responsive and personalised experience.

• Faster navigation and smoother performance
• Personalised content recommendations
• Built-in voice assistants and AI search
• Integration with tools like Microsoft Copilot and Google Gemini (subscription dependent)

LG also supports up to 5 years of webOS updates, helping keep your TV current for longer.

AI-Powered Convenience

A range of AI tools help make everyday use easier:

• AI Concierge suggests content based on your habits
• Intelligent Voice Recognition improves accuracy
• AI Chatbot helps troubleshoot issues quickly
• AI Agent assists with navigation and recommendations

These features work quietly in the background to simplify how you interact with your TV.

Clean, Modern Design
