J Calculation methods for screen dimensions
You can calculate more detailed screen dimension from the screen diagonal.
SW (m) = SD (") x 0.0221 SH (m) = SD (") x 0.0125
LW (m) = 0.0332 x SD (") - 0.049 LT (m) = 0.066 x SD (") - 0.055
* The results above are approximate and may differ slightly from the actual measurements.
