Heh, no. 4k is exactly four times the resolution of 1080p.
It is double the resolution, because resolution is expressed as an x,y pair. It is 4 times the pixel density for the same screen size.
Actually, display resolution refers to exactly what you call pixel density, and NOT the pixel dimensions. This error is so common that the term resolution has practically been redefined outside of the professional (science and engineering) space, but technically, display resolution and pixel density are the same thing.
1920 x 2 = 3840 (4K UHD)
That’s what he’s talking about.
Yeah but that would only be an increase in the horizontal resolution.. you'd have 3840 x 1080.
So you gotta double the vertical resolution too, which means you've now doubled both horizontal and vertical resolutions, which is equal to 4 times the initial resolution
