High-definition TV delivered the crispest picture we had ever seen, from breathtaking nature footage to the wrinkles on Brad Pitt's face, That's nothing - the next TV you buy will be four times as sharp. After years of gimmicky innovations such as 3D, gesture recognition and on-screen apps, ultra high-definition is finally a technology that could take off, Ultra high-definition is also known as 4K, which refers to the 3840-pixel horizontal resolution of the screens -in other words, nearly 4000. This is four times the 1080-pixel resolution of current high-definition screens, and creates much finer detail and greater texture, Even close up the picture doesn't pixelate. Most major manufacturers, including Sony, Samsung and LG, already have 4K products on the way, More important to the technology's uptake will be the fact that a host of content producers and distributors are lining up to support it as well, Until now there has not been enough 4K content to make it a realistic proposition, Normal HD content looks terrible on 4K screens.
