How this screen compares
PPI is only one part of display quality. Brightness, contrast, color accuracy, and viewing distance also matter.
How we calculate
We first calculate the diagonal resolution using the Pythagorean theorem, then divide it by the screen size in inches: PPI = √(width² + height²) ÷ size.
