Description: Suppose there is a 4K-resolution display in front of you. Its resolution is 3,840 pixels × 2,160 pixels, meaning there are a total of 8,294,400 pixels before your eyes. If you were to keep filling in one pixel per minute, starting from the edge and proceeding without pause, it would take more than 15 years to paint them all. And that screen is being refreshed 60 times every second. It is an overwhelming amount of information, so vast it is almost impossible to imagine.
