Nano Detail Enhancer for Finer Details
Nano Detail Enhancer technology analyses the image at a fine level and helps to highlight subtle textures, contrast and the spatial depth of individual scenes. The Alpha AI processor continuously works with the image to make films, series, photos and other content appear more natural. The result is a more detailed 4K image with better-rendered light and dark areas.
HDR10 Pro for More Vivid Contrast
HDR10 Pro technology uses LG's proprietary processing based on Dynamic Tone Mapping and optimises HDR10 content frame by frame. Bright areas can appear more vivid, while dark areas retain better definition. The LG 75NU800B3LA can therefore enhance the contrast and detail of HDR scenes without losing the natural image reproduction. HDR10 Pro here refers to the way HDR10 content is processed, not a separate HDR format.
Alpha 7 AI 4K Gen9 Processor
The Alpha 7 AI 4K Gen9 processor uses higher CPU and GPU performance for intelligent image processing and optimisation of individual scenes. It works with sharpness, contrast and spatial depth, and adapts the display to the nature of the content being watched. Advanced AI processing helps to create a cleaner 4K image with a more natural rendering of details.
4K Super Upscaling Enhances Lower Quality Sources
The 4K Super Upscaling feature processes lower-resolution images and brings them closer to 4K quality. At the same time, Dynamic Tone Mapping adjusts brightness and contrast according to the specific frame. The TV can thus highlight fine textures, contours and natural colour transitions even in content that was not originally created in 4K. The result depends on the quality and resolution of the source material.
AI Sound Pro with 9.1.2 Virtual Sound
The built-in 20W sound system uses two speakers in a 2.0 configuration. AI Sound Pro analyses the audio track and creates a virtual surround effect in up to a 9.1.2 configuration, while Clear Voice Pro helps to enhance dialogue. Thanks to intelligent processing, the sound adapts better to the nature of the content being watched and creates a more spatial backdrop even without additional speakers. The WOW Orchestra feature allows you to synchronise the speakers of a compatible LG soundbar with the TV.
webOS 26 with Multi AI Features
The webOS 26 operating system provides access to streaming services, apps, a web browser and smart features through the clear AI Hub interface. Multi AI Search allows you to use Google Gemini and Microsoft Copilot when searching. The combination of multiple AI services helps to get more accurate results and makes it easier to find content and answers to questions. The availability of individual AI features depends on the region, language and internet connection.
LG Shield and webOS Re:New
The LG Shield platform helps protect the TV's smart environment, user data and connected services. The webOS Re:New programme then allows you to get new versions of the operating system over the course of five years. The programme includes a total of four webOS updates over the five-year period, with the specific schedule depending on the model and its year of launch.
AI Magic Remote for Easier Use of AI Features
The webOS environment supports control via the AI Magic Remote with a dedicated AI button, scroll wheel and voice search. One button gives you quick access to supported artificial intelligence features and makes it easier to navigate the TV's interface.
LG Gallery+ and Gallery Mode
LG Gallery+ allows you to turn the screen into a decorative element with works of art, ambient videos and other visual content. There are more than 100 themes available, and the selection may change and expand over time. Gallery Mode allows you to display selected art even when you are not using the TV for normal viewing. Automatic brightness control also adapts the picture to the ambient light conditions. Full LG Gallery+ content may require a subscription.
Ready for Sports Broadcasts
TruMotion works with AI genre recognition and adjusts motion processing according to the type of content. For sports or faster scenes, it can help to achieve a more natural and smoother display. Sports Alert allows you to set notifications for match times, results and other important sporting events.
Gaming Features with VRR up to 60Hz
The LG 75NU800B3LA has a native 60Hz panel and supports VRR up to 60Hz, ALLM, HGiG, Game Optimizer and Game Dashboard. The Game Dashboard allows you to quickly change important game settings directly during gameplay, while ALLM automatically activates the low-latency mode when a compatible device is connected. The LG Gaming Portal also offers access to supported cloud gaming services including NVIDIA GeForce NOW.
Bluetooth with Extremely Low Latency
The TV supports compatible gaming controllers with Bluetooth Ultra Low Latency technology. With a supported controller, input latency can drop below 2.5ms, which helps to improve wireless control, especially when cloud gaming. The resulting latency may vary depending on the controller, game, application and network conditions.
Smart Home and Wireless Sharing
The LG 75NU800B3LA supports Apple AirPlay, Apple Home, Google Cast and the LG ThinQ app. The Home Hub allows you to access compatible smart home elements directly from the TV screen, and the environment also supports compatible Matter standard devices. This makes it easy to transfer content from your phone or tablet to the 75" screen while also using the TV as part of your smart home.
Slim Design
The LG 75NU800B3LA TV has a minimalist design that, despite its large 75" screen, fits elegantly into any modern interior. Without the stand, it measures 1,668×956×76mm and weighs 18.7kg. A VESA 400×300mm standard is provided for mounting on a compatible wall bracket. The large-format screen provides an impressive space for films, series, sports broadcasts and gaming.
