Mini RGB evo for Accurate and Vivid Colours
The LG 75MRGB88B3B uses 4K Mini RGB technology, which is designed for more accurate colour reproduction and a more impressive visual experience on the big screen. Tandem LED technology stacks multiple RGB colour layers to help achieve more vivid 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 rich shades when watching films, series, sports and photos. ¹
Higher Contrast with Precision Dimming
Precision Dimming technology helps to control the backlighting more accurately and improve contrast in individual scenes. The Alpha 8 AI 4K Gen3 processor intelligently works with light, dimming blocks, brightness, and details to make the picture more impressive and natural. The LG 75MRGB88B3B Smart TV can thus better render dark and light parts of the image and enhance the cinematic experience on the large 75" screen. ²
Alpha 8 AI 4K Gen3 Processor
The Alpha 8 AI 4K Gen3 processor takes care of image and sound processing. It uses artificial intelligence for a sharper 4K picture, more vivid colours and better content adaptation to your preferences. Compared to the previous generation, it offers up to 5× faster NPU performance, so it has enough power for advanced AI functions, picture optimisation and a personalised smart environment. ³
AI Picture with Upscaling to 4K
AI Super Upscaling helps to enhance the image to 4K quality, while Dynamic Tone Mapping Pro adjusts the brightness and details in individual scenes. AI Picture Pro recognises content and supports its sharper and more natural rendering. There is also AI HDR Remastering, which can optimise the colours, brightness and contrast of SDR content to give it a richer feel. ⁴
Cinematic Picture with Dolby Vision and FILMMAKER MODE
The LG 75MRGB88B3B TV supports Dolby Vision, HDR10 and HLG, so you can enjoy content with more pronounced contrast, colour depth and better detail rendering. FILMMAKER MODE helps to keep the cinematic picture as close as possible to the original intention of the creators and can adapt to the surrounding 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 content type, enhance voices, music and sound effects, and create a virtual 11.1.2 surround sound effect. This makes watching films, sports and concerts much more intense, and the sound fills the room better. ⁵ AI Object Remastering Pro also helps to enhance voices and key sound elements in the scene.

LG Gallery+ Transforms the LG 75MRGB88B3B Screen into Part of Your Interior
When you're not watching TV, it can become a stylish addition to your home. LG Gallery+ offers access to works of art, ambient videos and other visual content that turns the screen into a distinctive canvas. You can also use Google Photos, display your own memories or complement the visual content with music. ¹¹ The picture can also adapt to the ambient light conditions thanks to automatic brightness control.
Personalised Dashboard
The LG 75MRGB88B3B Smart TV can display important information in one place. On the personalised dashboard, you can check the weather, sports event notifications, Google Calendar, viewing reservations or information from the Home Hub. The TV thus serves not only for watching content, but also as a practical home information centre. ⁸ ¹²
Home Hub for a Smart Home
Home Hub connects smart devices in the household and allows for their convenient control directly on the TV screen. The LG 75MRGB88B3B 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 Google Cast and Apple AirPlay, so you can easily share content from your phone, tablet or laptop on the large 75" screen. The Multi View function allows you to display multiple sources at the same time, which is useful, for example, when watching sports, sharing content from your mobile or working with multiple types of entertainment at once.
LG Channels for More Entertainment
LG Channels brings diverse content from live broadcasts and on-demand offerings into one clear hub. This makes it easier for you to discover new shows, films and other content directly in the webOS environment without complicated searching. ¹⁴
Gaming Features for Smooth Gameplay
The LG 75MRGB88B3B is also ready for gaming. It offers a native 120Hz panel, VRR up to 144Hz, AMD FreeSync Premium, ALLM, HGiG and a Game Dashboard for quick access to gaming settings. Motion Booster 288 helps to reduce motion blur and support a smoother response when gaming at an optimised resolution. ¹³ The gaming features are also complemented by Dolby Vision support for games in 4K at 120Hz.
Bluetooth with Extremely Low Latency
The LG 75MRGB88B3B also caters to 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 more closely resembles a wired connection. ¹⁷
LG Gaming Portal
The LG Gaming Portal serves as a practical hub for discovering games. It provides access to gaming apps, cloud services, and games controllable with the remote or a gamepad. Gamers can easily find new content and quickly get to their favourite titles directly from the TV's interface. ¹⁴
WOW Orchestra for Connecting with an LG Soundbar
When connected to a compatible LG soundbar, you can use WOW Orchestra technology. This synchronises the sound of the TV and the soundbar into a single whole to create a fuller and more spatial sound experience. The function is particularly useful for films, concerts, and sports broadcasts, where you will appreciate a wider and more pronounced soundstage. ¹⁵
