Monitor PPI (pixels per inch) measures screen sharpness. Apple's "Retina" threshold is ~220 PPI, at which individual pixels cannot be seen at normal viewing distance.

Formül

PPI = √(H² + V²) / Diagonal (inches) | DPI on-screen typically 72–96; print quality requires 300 DPI

H: Horizontal pixel count
V: Vertical pixel count
PPI: Pixels per inch (px/in)

Adım Adım Kılavuz

1PPI = √(Width² + Height²) / Screen diagonal (inches)
2Higher PPI = sharper image at same viewing distance
3OS scaling (HiDPI/Retina) makes text readable at 144–220+ PPI
44K at 27" ≈ 163 PPI; MacBook Pro ≈ 220+ PPI
