Ultra HD!!!!
what you need to know about UHD
TV is gearing up for another revolution in picture quality.
Today's 1920 x 1080 resolution Full HD TVs present us with an image of around 2 million pixels. But a new generation of screens are coming that deliver an 8 million pixel image.
The technology used to be referred to as 4K, but it'll be known going foward as Ultra High Definition, or Ultra HD (UHD). These Ultra High Definition TVs have a resolution of 3840 x 2160 (give or take), and can offer unprecedented picture clarity.
But their introduction will prove complex in the extreme. Introducing an Ultra HD TV isn't like adding LED backlighting to an LCD. It's about orchestrating a seismic shift in the broadcast and entertainment infrastructure, not to mention rewriting the consumer electronics handbook.
So why would you want an Ultra HD TV?
High definition already comes in a variety of flavours, from 1280 x 720 upwards. All offer more picture information than the standard definition formats that came before. The more pixels that make up an image, the more detail you see and the smoother curved and diagonal lines become.
A high pixel count also allows images to go larger before they break up. Ultra HD is already making big inroads into the world of digital cinema.
Of course, perceived picture resolution is as much about viewing distance as resolution. What's the real difference between 720p and 1080p? The answer is about 2 metres. Increase the pixel density and you can sit closer without the pixel grid becoming obvious.
Some engineers dispute that you can see a difference between 2K and 4K on any screen less than 100inches. Go larger and the subtle nuances that make up a 4K picture become easier to appreciate.
Tapping into Ultra HD content
The good news is that there is Ultra HD content available in the vaults of the Hollywood majors. Increasingly movies are mastered at 4K resolution, both for commercial distribution and restoration projects. Hollywood has also begun shooting movies in Ultra HD and beyond.
Peter Jackson's upcoming 3D production of
The Hobbit, for example, is being shot on RED Epic digital cameras, capable of 5K resolution.
