Calculation methods for screen dimensions

You can calculate more detailed screen dimension from the screen diagonal.

Screen width (SW) and screen height (SH)

SW (m) = SD (") x 0.0221

SH (m) = SD (") x 0.0125

Minimum distance (LW) and maximum distance (LT)

PT-LB80NTU:

LW (m) = 0.0321 x SD (") - 0.04

LT (m) = 0.0388 x SD (") - 0.06

PT-LB75NTU:

LW (m) = 0.0318 x SD (") - 0.022

LT (m) = 0.0383 x SD (") - 0.046

* The results above are approximate and may differ slightly from the actual measurements.
