Product information
The LG OLED C6 55” TV makes everything you watch look richer and more punchy. Brightness Booster delivers a noticeably brighter picture, so highlights pop and scenes feel more lifelike. The α11 AI Processor 4K is constantly fine-tuning picture and sound as you watch, analysing what’s on screen in real time to balance brightness, contrast and detail more naturally. Self-lit OLED pixels mean blacks look genuinely black, not “darkish grey”. You get pinpoint contrast, crisp detail and colour that stays true, whether you’re watching in daylight or with the lights down. And if you’re firing up your console, a 165 Hz refresh rate and 0.1 ms response time keep gameplay fast, smooth and ultra-responsive.
