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) = 0.0297 x SD (") - 0.045 | LT (m) = 0.0592 x SD (") - 0.061 |
* The results above are approximate and may differ slightly from the actual measurements.
