Also, here are Yukipishi's results, calculated manually on a calculator using my algorithms, that you can use as reference when you fix and test the tool:

Monitor size: 23 inches

Monitor width: 20.05 inches - 509 mm

Monitor height: 11.28 inches - 287 mm

PPI: 95.78 (rounded to 96, btw now that I think about it the PPI and PP2 should be rounded to integer level)

PP2 (PPI^2): 9173.53 (rounded to 9174)

Pixel width: 0.26 mm

Pixel size: 0.0700 mm^2
