4K resolution
So while 4K UHD sounds like it has a pixel structures with 1/4 the area of 1080p, that does not happen with pixel shifting. Only a true 4K projector offers that level of resolution. That's why "true" 4K projectors cost so much more than 4K UHD projectors with otherwise similar feature sets. They produce smaller pixels, finer resolution, no compromising of detail or color from overlapping pixels. By comparison, the slight difference in aspect ratio between DCI and 3840×2160 pixel displays without overlap is insignificant relative to the amount of detail.
DirecTV-14
Michael White, chairman, president and CEO of DirecTV, was skeptical of the prospects for 4K in the past but was determined to stay on the bleeding edge of broadcast technologies. The 6,300 kg DirecTV 14 satellite uses Ka-band and Reverse Band Direct Broadcast Satellite (DBS) spectrum. DBS is expected to provide ample room for delivering 4K programs and other advanced services to customers.
