What is a 4K TV?
From HD to 4K
A 4K Ultra HD TV creates images using 8.3 million pixels - 6 million more than Full HD. This means every image on a 4K TV brings to life superior quality pictures with more depth and more clarity. The ultimate viewing experience.
With an incredible resolution of 3840 x 2160, a 4K Ultra HD TV
has almost quadruple the res of a full HD TV.
The difference is clear to see.

The future of TV
4K is the standard of television to come and many broadcasters and streaming services are increasing the amount of 4K content they offer. With a 4K Ultra HD TV you'll be set for all the highest quality new releases.
Get closer to the action
Combining enhanced colours and brightness, HDR allows images to appear more realistic and lifelike, with a greater sense of depth and tone. So you can enjoy brilliant brightness, shadow detail and vibrant colour just as the creator intended.
Ultra HD
Not all 4K UHD TVs offer the same viewing experience. TVs with the Certified Ultra HD or 4K HDR Ultra HD logos offer the 'true' Ultra HD experience. Certified Ultra HD is the logo used by Digital Europe, representatives of the digital technology industry in Europe, to guarantee that a TV has genuine 4K quality.
