We are just taking an example of the laptop screen

Width Resolution = 1920px

Height Resolution = 1080px

Diagonal = 15.6 Inch

You need to apply this Formula: √(width resolution²+  height resolution²) / Diagonal

PPI = √(1920²  + 1080²) / 15.6

PPI = √(3686400 + 1166400) / 15.6

PPI = √4852800 / 15.6

PPI = 2202.91 / 15.6

PPI = 141.21
