Bring cinematic quality into your living room with the LG OLED55G66LS 55 Inch OLED Evo AI G6 4K Ultra HD HDR Smart TV, a premium OLED that blends cutting-edge picture technology, intelligent processing, and a refined Gallery-style design. Whether you're watching films, gaming, or streaming, this TV is built to deliver a consistently impressive experience in any lighting condition.

Next-Level OLED Evo with Primary RGB Tandem 2.0

At the heart of this model is LG’s advanced Primary RGB Tandem 2.0 OLED panel, engineered to push brightness, colour accuracy, and contrast further than traditional OLED screens. Combined with Hyper Radiant Colour Technology and Brightness Booster Ultra, the TV produces rich, lifelike colours with exceptional depth and detail.

LG claims this panel delivers significantly higher brightness compared to previous generations, helping images stay vibrant even in well-lit rooms. Blacks remain perfectly deep, while highlights shine with striking clarity.

Reflection Free Premium Display

Bright rooms are no longer a problem. The screen features Reflection Free Premium technology, designed to reduce glare and reflections from windows or lighting. Certified by Intertek, it helps maintain the pure OLED experience—deep blacks, vivid colours, and strong contrast—without distractions from ambient light.

Intelligent Picture with Alpha 11 AI Processor Gen 3

Powering the visuals is LG’s Alpha 11 AI Processor Gen 3, designed to analyse and optimise every frame in real time. It enhances sharpness, reduces noise, and improves colour balance for a more natural, refined picture.

Key processing upgrades include:

• Dual AI Super Upscaling for improved clarity in lower-resolution content
• Faster CPU and GPU performance for smoother image handling
• Enhanced depth and realism across movies, sports, and gaming

The result is a picture that feels more immersive and intelligently tuned to what you're watching.

Gallery Design with Stand Flexibility

The Gallery design gives this TV a slim, near-wall aesthetic with ultra-thin bezels on all four sides for a clean viewing experience. Unlike wall-mounted-only models, the stand version includes a desktop stand, making it ideal for flexible placement in lounges, bedrooms, or modern apartments.

Even when switched off, the TV can display artwork or personal photos, turning it into a digital gallery piece rather than just a screen.

Cinematic Viewing with Dolby Vision & Filmmaker Mode

Designed for film lovers, this TV supports Dolby Vision HDR and Filmmaker Mode, ensuring content is displayed as the creator intended. Colours, frame rates, and aspect ratios are preserved accurately, while Ambient Light Compensation adjusts brightness depending on your room conditions.

A native 120Hz panel ensures smooth motion handling, whether you're watching fast-paced action or sports.

Built for Serious Gaming

Gamers get a premium experience thanks to ultra-fast responsiveness and advanced gaming features:

• Less than 0.1ms response time for near-instant reaction
• HDMI 2.1 support for 4K 120Hz console gaming and up to 4K 165Hz PC gaming
• NVIDIA G-SYNC and AMD FreeSync Premium for tear-free performance
• Dolby Vision Gaming support for richer HDR visuals
• LG Game Optimiser for quick access to key settings
• 4K 120Hz cloud gaming via NVIDIA GeForce Now

Everything is designed to reduce lag and keep gameplay smooth and responsive.

AI-Powered Smart TV Experience (webOS 26)

The latest webOS 26 brings a faster, more personalised smart platform with built-in AI features. It learns viewing habits and helps surface content you’re more likely to enjoy.

Highlights include:

• AI Concierge for tailored recommendations
• Intelligent Voice Recognition for easier navigation
• AI Chatbot for help and troubleshooting
• Microsoft Copilot integration for smarter content search
• Optional Google Gemini features for enhanced AI tools and Gallery+ content

LG also promises up to five years of OS updates, helping the platform stay current over time.

Immersive Sound with Dolby Atmos

Audio is handled by a 4.2 channel speaker system with Dolby Atmos support, delivering clear dialogue and a wider sound stage. AI Sound Pro enhances standard audio into a virtual multi-channel experience, making everything feel more immersive.

For even bigger sound, pairing with an LG soundbar enables WOW Orchestra, which combines TV and soundbar audio for a fuller, more layered output.
