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