Here’s their video illustrating the point from the former vice president of R&D at RCA (cool old school 60’s film footage included!):
Mankind seems to be on a constant quest for better quality TV, if you believe what all the hype coming from the television manufacturers. Which you shouldn’t. Nevertheless, as part of our eternal pursuit for the perfect moving image decoder, aka TV, we have now come to 4K HD TV.
The elevator pitch about 4k TV goes something like this: 4K Ultra HD TVs (also known as UHD TVs, ultra high def tv, ultra HD TV) deliver four times the picture resolution of 1080p HD.
What that means in terms of potential image clarity: incredibly fine detail, more video texture and an almost photographic clarity.
4K HD TV Ultra High Def is a spin off of the 4K digital cinema standard. The movie theaters show the images in native 4096 x 2160 resolution, this new TV format is 3840 X 2160.
