Mini RGB evo for precise and vibrant colours
The LG 65MRGB88B3B 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. Thanks to 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 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 image more impressive and natural. The LG 65MRGB88B3B smart TV can thus render dark and light parts of the image better and enhance the cinematic experience on the large 65" screen. 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 image, 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 improve the image up 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 colour, brightness and contrast of SDR content to make it look richer. ⁴
Cinematic picture with Dolby Vision and FILMMAKER MODE
The LG 65MRGB88B3B TV supports Dolby Vision, HDR10 and HLG, so you can enjoy content with more pronounced contrast, colour depth and better detail reproduction. FILMMAKER MODE helps to keep the cinematic image as close as possible to the creators' original intent 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, enhance voices, music and sound effects and 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 is also AI Object Remastering Pro, which helps to highlight voices and key sound elements in the scene.

LG Gallery+ transforms the LG 65MRGB88B3B 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 transforms the screen into a distinctive canvas. You can also use Google Photos, display your own memories or supplement the visual content with music. ¹¹ In addition, thanks to automatic brightness control, the image can adapt to the ambient light conditions.
Personalised Dashboard
The LG 65MRGB88B3B smart TV can display important information in one place. On the personalised dashboard, you can track the weather, sports event alerts, Google Calendar, viewing reservations or information from the Home Hub. The TV thus serves not only for viewing 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 65MRGB88B3B supports connection with LG ThinQ, Google Home and Matter standard devices, so you can manage compatible smart products from one place, monitor their status and conveniently control them. ¹² The TV supports Google Cast and Apple AirPlay, so you can easily share content from your phone, tablet or laptop to the large 65" 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 65MRGB88B3B is also ready for gaming. It offers a native 120Hz panel, VRR up to 144Hz, AMD FreeSync Premium, ALLM, HGiG and Game Dashboard for quick access to gaming settings. Motion Booster 288 helps 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 gaming in 4K at 120Hz.
Bluetooth with ultra-low latency
The LG 65MRGB88B3B also caters to cloud gaming with wireless controllers. The TV supports Bluetooth controllers with ultra-low latency, which helps 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 access their favourite titles directly from the TV's interface. ¹⁴
WOW Orchestra for connection with an LG soundbar
When connected to a compatible LG soundbar, you can use WOW Orchestra technology. This synchronises the TV and soundbar's audio into a single unit to create a fuller and more spatial sound experience. This feature is especially useful for films, concerts, and sports broadcasts, where you will appreciate a wider and more pronounced soundstage. ¹⁵
