Explanation

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