LG 55-Inch OLED evo G6 with Brightness Booster Ultra and 5-Year Panel Warranty

Next-Generation OLED Brightness and Colour:

The OLED55G66LS uses LG's Hyper Radiant Colour Technology, combining Brightness Booster Ultra, Perfect Black, Perfect Colour, and Reflection Free Premium in a single panel. Brightness Booster Ultra delivers up to 3.9x higher peak brightness than conventional OLED, while Perfect Colour has been independently certified by UL Solutions. The Reflection Free Premium coating is certified by Intertek to IDMS 11.2.2 standards, making this TV well suited to bright living rooms where reflections are a concern.

alpha 11 AI Processor 4K Gen3 with Dual AI Engine:

Picture and sound processing is handled by LG's alpha 11 AI Processor 4K Gen3, which drives AI Picture Pro, AI Sound Pro with Virtual 11.1.2 Up-mix, and AI Object Remastering Ultra. Dynamic Tone Mapping Ultra manages HDR content across Dolby Vision, HDR10, and HLG formats, and FILMMAKER MODE ensures cinema content plays back exactly as the director intended. The 4.2-channel speaker system outputs 60W, a step up from the 40W found on the C6 at the same screen size.

Serious Gaming Capability:

All four HDMI inputs support HDMI 2.1, enabling 4K at 120Hz for current-generation consoles and VRR up to 165Hz for PC gaming. Response time is certified by Intertek at 0.1ms (grey to grey), and VESA ClearMR 10000 certification confirms motion clarity. NVIDIA G-Sync Compatible, AMD FreeSync Premium, HGiG Mode, Dolby Vision for Gaming at 4K 120Hz, and the Game Optimiser dashboard with Game Dashboard are all included as standard.

webOS 26 with Multi-AI Architecture:

The TV runs webOS 26, powered by a multi-AI architecture that integrates Google Gemini and Microsoft Copilot alongside LG's own AI Concierge, AI Chatbot, and Intelligent Voice Recognition with Hands-free Voice Control. The platform supports Apple AirPlay, Apple Home, Google Cast, and Google Home, with Wi-Fi 6E and Bluetooth 5.3 for connectivity. LG Shield provides multi-layered OS security across 7 core technologies, and webOS Re:New guarantees software and security updates until 31 December 2030.

Gallery Design and 5-Year OLED Care+ Warranty:

The G6 is built around a Gallery design measuring just 27.2mm deep without the stand, and it is VESA-compatible (300 × 200mm) for flush wall mounting with an optional bracket sold separately. Every OLED55G66LS comes with OLED Care+ as standard: year one is covered by LG for panels, parts, and labour; years two through five cover panels and parts via Domestic and General, with labour charges applicable from year two onwards.

Setup and Care

Getting Started:

The AI Magic Remote MR26GB pairs automatically on first power-on. The on-screen webOS 26 setup wizard guides you through Wi-Fi, streaming account sign-in, and picture calibration in a straightforward sequence. HDMI 2.1 cables are recommended for 4K 120Hz and VRR gaming performance.

Wall Mounting:

The VESA mounting pattern is 300 × 200mm and accepts standard M6 bolts. A flush-fit Gallery wall bracket is available separately and reduces the gap between the TV and wall to a minimum. The stand height is adjustable between 742mm and 787mm to suit soundbar placement.

Picture and Sound Optimisation:

Selecting FILMMAKER MODE disables motion processing for accurate colour and frame rate from films and streaming content. The Game Optimiser Dashboard activates automatically when a console is detected via ALLM, setting the TV to the lowest input lag configuration. Auto Calibration is available for users with a compatible colour calibration device.

Screen Care:

OLED Care+ panel management software runs in the background and helps maintain long-term panel health. For cleaning, use a soft dry microfibre cloth and avoid pressing on the panel surface. The Eyesafe RPF 40 certification (UL) confirms reduced blue light output for extended viewing comfort.
