Your Quest for Quality 4K Starts Here.
With their ultra-high resolutions, high brightness panels, local dimming systems and sophisticated smart features, these great value TVs are an ideal entry point into the joys of 4K.

Delivers Four Times the Picture Resolution of a Normal HD TV

With their 3840 x 2160 resolutions, 4K Ultra HD TVs make pictures look so detailed and pristine that you feel like you’re looking at the real world through a window rather than watching TV. Especially when features like high brightness/high colour space panels and the powerful Quad Core Pro Engine are on hand to tease out every last tiny detail 4K has to offer.

An Advanced LED Backlight Design Which Produces a Wider Colour Range

By using a special LED LCD panel capable of producing a wider colour range, it covers more than 90% of DCI standards. Studio Master Colour TVs give you a more subtle, naturally toned colour palette which, unlike most LCD TVs, still looks authentic in any scene.

Quick, Intuitive Access to Just the Content You Want

A new FireFox OS-based home screen makes it easy to access the content you want with intuitive operation.

Enhanced Blacks for a More Natural Picture

The new generation of high brightness LCD panels are great for boosting colours and vibrancy. But they can only truly improve contrast if you can control their brightness in dark picture areas. Local dimming makes this possible by letting separate clusters of a TV''s backlights output different brightness levels, so brightness can be reduced for dark areas without compromising the intensity of bright areas.

Detailed, Crisp Images from Any Source

Dealing with the advanced smart features and 4K picture technologies we now expect on high-end TVs requires enormous processing power. Cue the Quad Core Pro engine. This cleverly separates the smart TV processing from the picture processing, so the smart elements run faster and smoother while pictures look cleaner, crisper and more refined – regardless of whether they’re web streams, broadcasts, Blu-rays or 4K feeds.
