Gadgets and Gizmos (India) - - FUTURE -

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.
