API, OpenAPI and WebMCP documentation

Explanation

DQHD 5120x1440 has a diagonal pixel count of 5318.64644435 px. diagonal_cm = (5318.646444350292 / PPI) x 2.54. For reference, input 1 PPI gives 13509.3619686 cm under this profile.

Method & Display Profile

Method basis: fixed DQHD 5120x1440 pixel grid (5120 × 1440) with one constant diagonal-pixel count for this route.
Profile reference: DQHD 5120x1440 (5120 × 1440), 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.
