Explanation

WU4K 5120x2160 has a diagonal pixel count of 5556.97759578 px. pixel_pitch_mm = 25.4 / PPI. For reference, input 1 PPI gives 25.4 mm/pixel under this profile.

Method & Display Profile

Method basis: fixed WU4K 5120x2160 pixel grid (5120 × 2160) with one constant diagonal-pixel count for this route.
Profile reference: WU4K 5120x2160 (5120 × 2160), so size, PPI, and pixel-pitch values all stay tied to the same display grid.
Consistency rule: calculator output and common-value rows keep the same fixed display profile in both directions.
