LG 55-Inch Mini LED TV with RGB Evo Colour and AI 4K Processing
Mini RGB Evo Panel with Certified Colour Accuracy:
The 55MRGB88B6B uses LG's Mini RGB evo panel technology, which separates and purifies the red, green, and blue light spectrums at the backlight level for exceptionally clean, precise colour. This display holds TÜV Rheinland certification for High Purity RGB Spectrum and Intertek certification for Double 100% colour coverage across both DCI-P3 and Adobe RGB colour spaces - figures that matter equally to film viewers and creative professionals working with photo or video content.
Precision Dimming and the alpha 8 AI Processor 4K Gen3:
Contrast is handled by Precision Dimming, which works in step with the alpha 8 AI Processor 4K Gen3 to manage the Mini RGB backlight blocks intelligently frame by frame. The processor's NPU runs up to five times faster than its predecessor, and its memory capacity is 20% larger, giving features like AI Picture Pro, AI Super Upscaling 4K, AI Object Remastering Pro, and AI HDR Remastering more room to work with. Dynamic Tone Mapping Pro and FILMMAKER MODE™ round out the picture processing suite for HDR film content.
Built for Console and PC Gaming:
All four HDMI ports are HDMI 2.1, supporting 4K at 120Hz natively and Variable Refresh Rate up to 144Hz. AMD FreeSync Premium, ALLM, Dolby Vision Gaming at 4K 120Hz, and HGiG Mode are all included, alongside Motion Booster 288 and Motion Pro for fast-moving content. The Game Optimiser dashboard, LG Gaming Portal, and Bluetooth Ultra Low Latency controller support (input lag under 3.0 ms) complete a gaming setup that works with PS5, Xbox Series X/S, and PC without additional configuration.
webOS 26 with Google Gemini and Microsoft Copilot:
The TV runs webOS 26, which integrates Google Gemini and Microsoft Copilot AI assistance alongside LG's own AI Hub, AI Concierge, AI Voice ID, and AI Chatbot features. The webOS Re:New Program provides free OS upgrades for up to five years, extending the useful lifespan of the software platform beyond the typical two-to-three-year cycle. AirPlay 2, Google Cast, Apple Home, Google Home, and Matter compatibility mean the TV fits into most existing smart home setups without friction.
Audio and Connectivity:
The built-in speaker system outputs 20 W RMS across two channels, with AI Sound Pro providing a virtual 11.1.2 channel up-mix and Dolby Atmos decoding for compatible content. Clear Voice Pro improves dialogue clarity during normal viewing. Connectivity includes Wi-Fi 5 (802.11 a/b/g/n/ac), Bluetooth 5.3, one Ethernet port, two USB ports, one optical audio output, and one CI/CI+ slot, with dual RF inputs for antenna and cable connections. VESA mounting is 300 × 300 mm.

Setup and Care
Getting Started:
Attach the central stand before positioning the TV on a firm, level surface. Connect your aerial, satellite, or cable feed to the RF inputs and run the on-screen channel scan to populate the tuner. The AI Magic Remote pairs automatically during first-time setup via webOS 26's guided configuration wizard.
Wall Mounting:
The 55MRGB88B6B uses a standard 300 × 300 mm VESA pattern. Use a bracket rated for at least 18.9 kg and ensure wall fixings are appropriate for the wall material. Leave at least 100 mm of clearance around the ventilation areas to allow adequate airflow.
Optimising Picture Quality:
FILMMAKER MODE™ activates automatically when supported content is detected, disabling motion smoothing and colour adjustments for accurate playback. For gaming, open Game Optimiser via the quick settings panel - this applies the correct low-latency settings for whichever console or PC is connected. AI Picture Wizard guides you through a personalised calibration routine if you prefer a manual starting point.
Cleaning and General Care:
Wipe the screen with a soft, dry microfibre cloth using light, even strokes. For the casing and stand, a lightly dampened cloth is suitable. Avoid aerosol sprays, abrasive materials, and any liquids applied directly to the screen surface, as these can damage the panel coating.
