Product Summary & Benefits Tech Specs & Box Contents

Product Summary

The LG OLED evo AI C6 C66LB is a premium 2026 4K OLED Smart TV range available in 42-inch, 48-inch, 55-inch, 65-inch, 77-inch and 83-inch screen sizes. Combining individually controlled self-lit OLED pixels with LG’s flagship Alpha 11 AI Processor 4K Gen3, it delivers deep blacks, precise highlights and rich colour for films, television, sport and gaming.

Because every OLED pixel can illuminate or switch itself off independently, dark scenes benefit from true black levels and precise contrast without the blooming associated with conventional backlit televisions. Perfect Black and Perfect Colour technology helps maintain accurate, vivid colour and detailed shadows across a wide range of viewing conditions.

Picture performance is tailored to the selected screen size. The 48-inch, 55-inch and 65-inch models feature Brightness Booster processing for brighter highlights and improved detail, while the 77-inch and 83-inch models step up to Hyper Radiant Colour Technology with Brightness Booster Pro for even greater brightness, colour volume and visual impact.

The C6 is also designed for premium smart entertainment and gaming. webOS 26 brings streaming services, personalised recommendations and AI features together in one interface, while support for 4K Variable Refresh Rate up to 165Hz, NVIDIA G-SYNC compatibility, AMD FreeSync, Dolby Vision gaming and a response time of less than 0.1ms makes it an excellent choice for modern games consoles and PCs.

Our Trustpilot reviews

★★★★★
What an amazing company. Anna in the Glasgow branch has been so informative and helpful with my order. Sam in the Aberdeen branch has an incredible knowledge of older amps and speakers.
Alan

★★★★★
I bought a full system from the Aberdeen shop. Christian was very attentive throughout the whole process. I found that all the staff in the shop were both knowledgeable and helpful. I would strongly recommend Holburn Hi-Fi to anyone thinking about buying a full or part Hi-Fi system.
Peter

★★★★★
Jesse is very professional and always happy to help in the Glasgow Audio store. He is very knowledgeable about the products. Highly recommend.
Kyle

★★★★★
The guys at Holburn Hifi were fantastic from start to finish. Explained everything clearly and in simple terms which I really appreciated as I was lost amongst all the info I had seen online. There was no hard sell and certainly an understanding of my budget. I can’t recommend Holburn Hi Fi highly enough. Thanks to Ian, Sam and Christian.
Richard

★★★★★
Dropped in not really knowing what I wanted. Sam was most helpful, steering me towards a solution, and avoiding going over the top. From that we moved on to updating our wifi coverage towards a network. Here, Alain was equally helpful.
