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.
What are the benefits of a 4K TV?
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.
