Mini RGB evo for Accurate and Vibrant Colours

Tandem LED technology stacks multiple RGB colour layers to help achieve more vibrant colour reproduction. With RGB Primary Colour Pro, the TV has dual 100% colour volume certification for the DCI-P3 and Adobe RGB standards, so you'll appreciate the rich shades when watching films, TV series, sports and photos. ¹
Higher Contrast with Precision Dimming
Precision Dimming technology helps to more accurately control backlighting and improve contrast in individual scenes. The Alpha 8 AI 4K Gen3 processor intelligently works with light, dimming blocks, brightness and detail to make the picture more impressive and natural. The LG 55MRGB88B6B Smart TV can therefore better render dark and light parts of the picture and enhance the cinematic experience on the large 55" screen. ²
Alpha 8 AI 4K Gen3 Processor

It uses artificial intelligence for a sharper 4K picture, more vivid colours and better content customisation to your preferences. Compared to the previous generation, it offers up to 5× faster NPU performance, so it has plenty of power for advanced AI features, picture optimisation and a personalised smart environment. ³
AI Picture with Upscaling to 4K
AI Super Upscaling helps improve the picture to 4K quality, while Dynamic Tone Mapping Pro adjusts brightness and detail in individual scenes. AI Picture Pro recognises content and supports sharper, more natural rendering.

Cinematic Picture with Dolby Vision and FILMMAKER MODE
The LG 55MRGB88B6B TV supports Dolby Vision, HDR10 and HLG, so you'll enjoy content with more pronounced contrast, colour depth and better detail rendering.

Surround Sound with AI Sound Pro
The built-in 20W 2.0-channel sound is complemented by Dolby Atmos and AI Sound Pro technology. The TV can adjust the sound according to the content type, enhancing voices, music and sound effects to create a virtual 11.1.2 surround effect. This makes watching films, sports and concerts much more intense, and the sound fills the room better. ⁵ There's also AI Object Remastering Pro, which helps to enhance voices and key sound elements in a scene.
