SwitchExplanation
Formula: pixel_pitch_mm = 25.4 / PPI. Why: this route fixes the resolution profile to WU4K 5120x2160, so diagonal pixels stay constant for every calculation.
WU4K 5120x2160: a fixed resolution profile with 5120 × 2160 pixels, used as the density basis for this page.
Pixels per inch (PPI): a screen-density quantity in this family that depends on the selected resolution profile.
Pixel pitch (mm): a screen-density quantity in this family that depends on the selected resolution profile.
This route is useful when comparing panel sharpness and physical pixel spacing for the fixed WU4K 5120x2160 resolution profile.
This page is profile-dependent rather than universal because PPI, screen size, and pixel pitch depend on the selected resolution profile (WU4K 5120x2160).
