Resolution actually is an AREA (TWO-dimensional) measurement. Thus why you normally need TWO numbers to describe it properly (width and height or whatever you want to call them). The end result is a PRODUCT telling you the exact number of pixels the screen contains. An UHD does indeed contain exactly four times the number of pixels a 1080p screen does. Simple math will demonstrate. You double each dimension so you multiply each one by two. Multiplication is commutative so you can move each 2x to the side and combine them to get 4x the original resolution. Thus doubling both dimensions quadruples the pixel count (what we could call the resolution, which is always shown as a product).
