With RGB Primary colour Pro, the TV has dual 100% colour volume certification for DCI-P3 and Adobe RGB standards, so you'll appreciate the rich shades when watching films, series, sports and photos. ¹
Higher Contrast with Precision Dimming
Precision Dimming technology helps to control backlighting more precisely 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 86MRGB88B3B Smart TV can therefore render dark and light parts of the image better and enhance the cinematic experience on the large 86" screen size. ²
Alpha 8 AI 4K Gen3 Processor
The Alpha 8 AI 4K Gen3 processor handles image and sound processing. 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 functions, image optimisation and a personalised smart environment. ³
AI Picture with Upscaling to 4K
AI Super Upscaling helps to enhance the picture to up to 4K quality, while Dynamic Tone Mapping Pro adjusts the brightness and detail in individual scenes. AI Picture Pro recognises the content and supports its sharper and more natural rendering. There is also AI HDR Remastering, which can optimise the colour, brightness and contrast of SDR content to give it a richer feel. ⁴
Cinematic Picture with Dolby Vision and FILMMAKER MODE
The LG 86MRGB88B3B TV supports Dolby Vision, HDR10 and HLG, so you can enjoy content with more pronounced contrast, colour depth and better detail. FILMMAKER MODE helps to keep the film picture as close as possible to the original intention of the creators and can adapt to the ambient environment for a more pleasant viewing experience. ¹⁶
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 type of content, highlighting 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 AI Object Remastering Pro is also included to help highlight voices and key sound elements in the scene.

Home Hub for a Smart Home
Home Hub connects smart devices in your home and allows you to conveniently control them directly on your TV screen. The LG 86MRGB88B3B supports connection with LG ThinQ, Google Home and Matter standard devices, so you can manage compatible smart products, monitor their status and control them conveniently from one place. ¹² The TV supports both Google Cast and Apple AirPlay, so you can easily share content from your phone, tablet or laptop to the large 86" screen.

LG Channels for More Entertainment
LG Channels brings a variety of content from live broadcasts and on-demand offerings into one clear hub. This makes it easier to discover new shows, films and other content directly in the webOS environment without complicated searching. ¹⁴

Bluetooth with Extremely Low Latency
The LG 86MRGB88B3B also thinks about cloud gaming with wireless controllers. The TV supports Bluetooth controllers with extremely low latency, which help to reduce input lag to less than 2.5ms. This allows you to enjoy smoother and more responsive control that is closer to a wired connection. ¹⁷

When connected to a compatible LG soundbar, you can use WOW Orchestra technology. It synchronises the TV and soundbar sound into a single unit to create a fuller, more spatial sound experience. The feature is especially useful for films, concerts and sports broadcasts, where you'll appreciate a wider and more pronounced soundstage. ¹⁵
