The pitch represents the size of a pixel and here are a few values: 1  in 23'' Full HD for instance, the pitch is 0.25mm so the screen displays 96 ppi. 2  in 24'' / 1920 x 1200 or in 30''/ 2560 x 1440, the pitch is 0.27mm and the screen has a resolution of 94 ppi. 3  in 25'' / 2560 x 1440, the pitch is 0.22mm only and the resolution is 115 ppi.
