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.
