DPI stands for Dots Per Inch and it represents the number of individual dots or pixels that can be displayed in one inch of a digital image or on a screen.

In the case of a screen with a resolution of 1920x1080, the DPI value will depend on the physical size of the screen. The DPI calculation formula is as follows:

DPI = (sqrt(1920^2 + 1080^2)) / diagonal size of the screen

For example, if the screen is 24 inches diagonally, the DPI calculation would be:

DPI = (sqrt(1920^2 + 1080^2)) / 24

= (sqrt(3686400 + 1166400)) / 24

= sqrt(4852800) / 24

= 2200 / 24

= 91.67 DPI

Therefore, a screen with a resolution of 1920x1080 and a physical size of 24 inches would have a DPI of approximately 91.67.
