Re: Ultra HD at CES Surely you jest. 4K is four times the resolution of 1080p.
It is a greater leap in visual fidelity than 480p to 720p was. 480p went from 300,000 pixels to around 900,000. 1080p to 4K is going to go from around 2,000,000 pixels to over 8,000,000.
I have some 4k videos. Even downscaled from 4k to 1080p they look better than any 1080p video I have ever seen, and I own a lot of Blu-rays.
This is big, and it is an important stepping stone to 8k, just like 720p was an important stepping stone to 1080p.
At over 33 million pixels, 8k represents the limitation of human eye sight. That resolution should be our ultimate goal.
