What Hi-Fi? 5-Star Review Highlights

“It’s a benchmark that its rivals will find very hard to match, let alone surpass.” – ‘What Hi-Fi?’ 5 star review

“The C6 proves processing can make a big difference, delivering a brighter, richer and more refined OLED picture than its already excellent predecessor.” – ‘What Hi-Fi?’ 5 star review

These reviews underline the biggest strength of this model: LG’s improved AI processing doesn’t just tweak the picture—it noticeably upgrades brightness, colour depth and overall clarity compared to earlier OLED generations.

OLED evo – What Actually Makes It Better?

OLED evo isn’t just a branding upgrade. It’s a refined version of OLED technology that improves how much light each pixel can produce.

Because every pixel is self-lit:

• Blacks are truly black (pixels switch off completely)

• Contrast is extremely precise (bright and dark areas don’t bleed into each other)

• Colours appear more natural and controlled

The evo layer adds extra brightness efficiency, meaning this TV performs better in brighter rooms compared to standard OLED models. You get the deep cinematic look OLED is known for, but with improved punch in highlights like sunlight, reflections and HDR effects.

Alpha 11 AI Processor Gen 3 – The “Brain” Behind the Picture

This TV is powered by LG’s Alpha 11 AI Processor Gen 3 , and this is where most of the “smart” improvement happens.

Instead of using one fixed picture setting, the processor:

• Analyses every frame in real time

• Detects faces, objects, backgrounds and motion

• Adjusts sharpness, brightness and colour dynamically

What this means in real viewing:

• Older HD content looks closer to 4K thanks to AI upscaling

• Faces look more natural, not overly sharpened

• Fast motion (sports, action scenes) stays clearer

• Dark scenes retain detail instead of looking flat
