5 Key Features of the LG C6 (2026)
The 77" C6 steps up to Brightness Booster Pro — exclusive to the 77" and 83" models. LG's Hyper Radiant Colour Tech delivers up to 3.2x higher peak brightness than conventional OLED, with Perfect Black maintained simultaneously.
*Peak brightness up to X3.2 higher than conventional OLED at 3% window, based on internal measurements.
For the first time, the C-series gets LG's most powerful processor.

More precise colour and significantly improved gradation over the outgoing C5.
*Alpha 11 AI Gen3 processor featured across LG C6 and G6 series (2026).

LG OLED83C66LB — 83” OLED evo AI 4K Smart TV (2026)
The LG C6 is the benchmark mid-range OLED for 2026, and the 83” is the largest screen in the range — delivering a genuinely cinematic picture that fills the room. For the first time, the C-series gets LG’s flagship Alpha 11 AI Gen3 processor — the same chip as the premium G6 — bringing a meaningful leap in brightness, picture precision and colour handling over its predecessor.
Brightness Booster Pro & Alpha 11 AI Gen3 Processor
The OLED83C66LB benefits from LG’s Brightness Booster Pro — a step up from the standard Brightness Booster on smaller C6 sizes, delivering 3.2x brighter highlights than conventional OLED. Combined with the Alpha 11 AI Gen3 processor, every pixel is pushed to its maximum potential, with real-time analysis applying the optimum picture and sound settings for your content automatically.
Certified Perfect Black & Perfect Colour — In Any Light
Over 8.3 million self-lit pixels give the C66LB its fundamental advantage: every pixel controls its own light output, 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. The result is an image that holds its depth and accuracy whether the room is bright or dark, and from any angle in the room.
Adjustable Height Stand
The 83” C6 features an adjustable height stand, giving you two viewing positions — 1,096mm in the lower position or 1,144mm in the higher position. This is a genuinely useful feature if you’re placing the TV on a low media unit or need to fine-tune the viewing angle for your room. If you’re planning to wall-mount, our installation team can advise on the ideal height — call us on 01252 811800 or pop in to the Fleet showroom.
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 C6 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, AMD FreeSync Premium, ALLM and a 0.1ms response time. Game Optimizer and the Game Dashboard give you immediate access to gaming settings. Dolby Vision Gaming at 4K 120Hz is also supported.
Extraordinary Cinema — Dolby Vision, Dolby Atmos, Filmmaker Mode
Dolby Vision and Ambient 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 40W of audio output that tracks and follows the on-screen action.
