The Maths: It’s called Ultra High Definition or UHD, 4K is horizontal pixels on a rectangular frame. So multiply vertical 2K pixels and total = approx. 8 million or 8 megapixels (8MP). Actual native Ultra HD resolution = 3840 x 2160 = 8,294,400 pixels. So, slightly less than 4K top and slightly more than 2K side = a bit over 8MP total. Close enough for horseshoes, rock and roll, and marketing.
Infrastructure? Mobile devices using Qualcomm QCOM +1.11%’s Snapdragon 805, will have 4K cams, data pathways, processing, memory, and display. So, a device can capture 4K, compress it, move it around, process it, and put it on a screen to view on YouTube or Hulu.
End to end 4K is already showing up in movie theaters and video gaming.
Projectors: Most Barco projectors are now shipping in 4K laser, and Casio has just released the industry’s first low cost, full 4K laser commercial projector, the L8300 – shipping now. Call your rep if you want to see it.
