From the groundbreaking Star Wars to the sensational Avatar, then 2012, Gravity to Furious 7, George Lucas, James Cameron and other Hollywood directors all devote themselves to provide us with a visual feast, constantly revolutionizing Hollywood's visual effects.

What is 8K? What is 8K TV? It's too boring to explain 8K with various professional specifications for you, for it's really hard to understand. So I prefer the comparison method to illustrate you "What is 8K". Just as the old saying goes, comparison tells you the difference. Here I compare 8K with 2K, 4K, Full HD 1080P, majority of which are familiar to you so as to better digest the newcomer 8K.
Take away the part of 8K resolution history, and let's cut to the chase. When you watch movies or TV shows on a full HD TV with 1080P, you can see the image with 2.07 million pixels; you will watch the video picture with 2.21 million pixels for the traditional digital cinema with 2K resolution; and you can enjoy the much sharper image with 8.85 million pixels in IMAX 4K cinema. More incredibly, 8K resolution (7680×4320) is 16 times bigger than 1080P FHD and 4 times as many as 4K UHD. See the picture on the right.

8K vs 4K vs 2K vs 1080P: Another Advantage of 8K
Another advantage of 8K high definition display is to have each pixel be indistinguishable from another to the human eye from a much closer distance. Based on the NHK, the ideal viewing distance is 0.75x the height of the display and the viewing angle for 8K is 100°, which brings much more exciting effects than 2K 4K with 55°viewing angle. (Below the table will show the specific distance according to the 8K TV size.)
