1920(horizontal pixels) times 1080(vertical) = 2,073,600 pixels Full HD
3840(horizontal) times 2160(vertical) = 8,294,400 pixels 4k

"4K" is double the resolution of 1080P but because of how rectangles work(length times width), it internally contains 4 times the amount of pixels. Also there's alot of confusion about the term 4K because it refers to the horizontal resolution, where 1080P referred to the vertical. Not sure why they did this, probably for marketing TVs and it being easier to say than 2160P or Ultra High Definition.

Yep, this clears things up a lot, thanks.
