ULTRA DEFINITION, 4K & 8K
While we feel proud of our Full HD (1920x1080p) televisions, screens with a mindboggling 3840x2160p resolution already seem to be on their way. But the chances are this definition will be more popular in the extra-large screen sizes, like the 82-inch UD LCD showcased by Samsung. TVs with these screens are expected to have good zoom features that let users get a up-close and personal view of the action. Just imagine you having a better view of a caught-behind decision than any one on the cricket ground! Since UD content will be hard to find, the chances are such TVs will be able to play Full HD and HD Ready content too.
4k is rounding up a 3840 x 2160p resolution to 4000p. It is different from other displays because you won’t notice individual pixels on the screen however close you are to it. There is no content in 4K now, but everyone seems to be preparing for the next jump in pixel count.
8K or Ultra HD has a resolution of 7680x4320p (33.2 megapixels), which is 16 times the number of pixels of the 1080p HDTV standard (1920x1080 or 2.1 megapixels). BBC Research & Development has plans to trial UHDTV during the 2012 London Olympics, erecting 15-m display screens at three locations in London, Glasgow, and Bradford.
