Discover the LG OLED42C66LB 42" 4K OLED evo AI Smart TV, designed to deliver stunning picture quality and immersive sound in a compact size that fits almost anywhere. This TV solves the problem of smaller screens that compromise on contrast, black levels and gaming performance by bringing genuine OLED technology to a 42-inch display, making it perfect for bedrooms, kitchens, home offices, apartments or dedicated gaming setups where a larger screen would be impractical. Powered by the α11 AI processor smartly enhancing image clarity and audio, with Certified Perfect Black and Colour technology ensuring vibrant hues and deep contrast whether in bright daylight or a dark room, and Dolby Vision with Filmmaker Mode bringing cinema-grade visuals to life, you get exceptional quality in a size that works for tighter spaces.

42-Inch OLED – Premium Picture for Smaller Spaces
The 42-inch size is perfect for bedrooms, apartments, kitchens, home offices, dorm rooms or dedicated gaming desks where a 55-inch or larger screen simply will not fit. Despite its compact footprint, this TV carries the same advanced OLED evo technology found in LG's larger models, delivering perfect blacks, infinite contrast and stunning brightness. You do not have to sacrifice picture quality just because you have limited space.

OLED evo – Brighter, More Detailed Visuals
OLED technology uses self-illuminating pixels that turn on and off independently, producing true blacks because pixels completely switch off when displaying dark scenes. With OLED evo, brightness levels are improved further, helping highlights stand out more clearly while maintaining natural tones. You see exactly what the director intended, with deep shadows, bright highlights and natural skin tones that look lifelike even in bright rooms, all on a screen size that fits where larger TVs cannot.

α11 AI Processor – Smarter Picture and Sound
Powered by LG's most advanced processor, the α11 AI Processor Gen 3 enhances everything you watch in real time. It delivers sharper image clarity with advanced AI upscaling, more natural colours and improved depth, better motion handling for fast-paced scenes, and enhanced sound processing for clearer dialogue. With a faster CPU and GPU compared to previous generations, performance feels noticeably smoother in both picture processing and Smart TV navigation.

Certified Perfect Black and Colour Technology
The certified Perfect Black capability creates infinite contrast and allows colours to appear richer and more accurate, with no backlight bleed or grey haze. The TV performs brilliantly in any lighting, maintaining deep blacks and vibrant colours whether you are watching in bright daylight or a dark room. You get consistent, premium picture quality regardless of the time of day.

Dolby Vision and Filmmaker Mode
Dolby Vision brings cinematic HDR to your home with scene-by-scene metadata that adjusts brightness, colour and contrast for every frame. Filmmaker Mode preserves the director's original settings, turning off motion smoothing and maintaining the intended frame rate and colour grading. Films look exactly as they were meant to be seen, with authentic motion, accurate colours and no artificial smoothing or processing.

Ultimate Gaming Performance
The TV supports low input lag, near-instant response time (under 0.1ms) and HDMI 2.1 features that make it ideal for modern console and PC gaming. Game Optimiser mode provides quick access to picture presets and gaming-specific settings, with support for 4K 120Hz gaming, NVIDIA G-SYNC and AMD FreeSync Premium. The 42-inch size is perfect for a dedicated gaming monitor or small gaming setup, and OLED's instant pixel response eliminates motion blur entirely.

webOS Smart Platform with Advanced AI
The webOS platform offers an intuitive, customisable home screen with quick access to streaming apps, live TV and connected devices. Advanced AI learns your viewing habits and provides personalised content recommendations, making it easier to find something to watch. You spend less time scrolling and more time watching.

AI Magic Remote for Effortless Navigation
The included AI Magic Remote supports voice control, point-and-click navigation and built-in microphone for hands-free operation. It works like a computer mouse on screen, letting you point and click instead of pressing arrow keys repeatedly. No more typing with an on-screen keyboard or navigating complex menus.

Smooth Motion Handling
OLED's near-instant response time combined with the 120Hz native refresh rate ensures perfectly smooth motion across sports, action films and gaming. Motion blur is virtually eliminated, making fast scenes look clean and controlled.

AI Sound Pro
The processor analyses audio in real time, upscaling standard content to virtual surround sound and improving dialogue clarity. AI Sound Pro adapts audio based on what you are watching, boosting voices in news programmes and widening the soundstage for movies.

Digital Tuners for Versatile Broadcast Support
The TV includes built-in digital tuners supporting DVB-T2 (Freeview HD), DVB-C (cable) and DVB-S2 (satellite), connecting to a standard coaxial antenna for free-to-air channels. You can watch live broadcast TV without a separate set-top box.

Sleek, Compact Design
The TV features an ultra-slim profile with nearly invisible bezels, allowing the picture to take centre stage. Its compact 42-inch size makes it ideal for mounting on smaller walls or placing on desks and stands.
