Explanation

5K 5120x2880 has a diagonal pixel count of 5874.41912022 px. diagonal_inches = 5874.4191202194625 / PPI. For reference, input 1 PPI gives 5874.41912022 in under this profile.

Method & Display Profile

Method basis: fixed 5K 5120x2880 pixel grid (5120 × 2880) with one constant diagonal-pixel count for this route.
Profile reference: 5K 5120x2880 (5120 × 2880), 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.
