LG OLED55G66LS — 55” OLED evo AI 4K Smart TV (2026)

The LG G6 is LG’s premium Gallery-class OLED for 2026, and the 55” G66LS stand version is where the G6 really pulls away from the C6. Brightness Booster Ultra delivers up to 3.9× the brightness of a conventional OLED — a meaningful step above the Brightness Booster found on the C6. Add Reflection Free Premium anti-reflection technology, 60W of audio output and OLED Care+ with a 5-year extended panel warranty, and the case for choosing the G6 over the C6 at this size is compelling.

Brightness Booster Ultra & Alpha 11 AI Gen3 Processor

The OLED55G66LS uses LG’s Brightness Booster Ultra — a significant step above both the standard Brightness Booster on the C6 55” and the Brightness Booster Pro on the G6 48” — to deliver genuinely luminous highlights without sacrificing the contrast and colour accuracy that OLED is known for. The Alpha 11 AI Gen3 processor analyses everything you watch in real time, applying the optimum picture and sound settings automatically. Dynamic Tone Mapping Ultra and AI HDR Remastering ensure every source looks its absolute best.

Reflection Free Premium — Watch in Any Light

Unlike the C6, the G6 55” features Reflection Free Premium anti-reflection technology — an advanced optical layer that significantly reduces glare from windows and room lighting without dimming the picture or washing out blacks. Whether you’re watching in a bright daytime living room or a darkened cinema space, the picture holds its depth and accuracy throughout.

Certified Perfect Black & Perfect Colour — In Any Light

Over 8.3 million self-lit pixels give the G66LS its fundamental advantage: every pixel controls its own light output independently, so blacks are absolute and contrast is infinite. LG’s Perfect Black and Perfect Colour are both independently certified by UL — not just marketing claims. Auto Calibration lets the TV calibrate itself for the most accurate picture in your specific room, in any lighting condition, from any seat.

webOS 2026 — Smart TV Powered by Gemini & Copilot

LG’s webOS 2026 is one of the best smart TV platforms available. Every major streaming service is built in: Netflix, Prime Video, Disney+, Apple TV+, BBC iPlayer, ITVX, Channel 4, Channel 5, NOW and more — plus LG Channels for free streaming content. Controlled by the AI Magic Remote with hands-free voice recognition, AI Chatbot for picture and sound adjustments by voice, and AI Voice ID for personalised recommendations per user. LG’s webOS Re:New programme means the platform stays up to date with software upgrades for five years.

Ultimate Gaming — 165Hz, G-Sync, FreeSync, 0.1ms

The G6 holds nothing back for gaming. Four HDMI 2.1 ports, 4K@120Hz for PS5 and Xbox Series X, VRR up to 165Hz for PC, NVIDIA G-Sync Compatible, AMD FreeSync, ALLM and a less-than-0.1ms response time. HGiG Mode, Game Optimizer and the Game Dashboard give you immediate access to all gaming settings. Dolby Vision Gaming at 4K 120Hz is also supported. Quick Frame Transport and Quick Media Switching further reduce input lag and switching delays.

Extraordinary Cinema — Dolby Vision, Dolby Atmos, Filmmaker Mode

Dolby Vision and Filmmaker Mode deliver the picture exactly as the director intended, with Filmmaker Mode automatically adjusting to your room’s lighting while keeping colour accuracy intact. Dolby Atmos with Alpha 11 AI Sound Pro (Virtual 11.1.2 up-mix) means 60W of audio output — 50% more than the C6 55” — that tracks and follows the on-screen action with precision.

OLED Care+ — 5-Year Extended Panel Warranty

The G6 includes LG’s OLED Care+ technology — advanced panel management refined over 13 years of OLED development — alongside a 5-year extended panel warranty as standard. Year 1 is covered by LG, years 2–5 by Domestic & General.
