Explanation

UWQHD 3440x1440 has a diagonal pixel count of 3729.23584666 px. PPI = 3729.2358466581327 x 2.54 / diagonal_cm. For reference, input 1 cm gives 9472.25905051 PPI under this profile.

Method & Display Profile

Method basis: fixed UWQHD 3440x1440 pixel grid (3440 × 1440) with one constant diagonal-pixel count for this route.
Profile reference: UWQHD 3440x1440 (3440 × 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.
