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 0.0203 | SH (m) = SD (") x 0.0152 |
Minimum distance (LW) and maximum distance (LT) |
|
LT (m) = 0.0358 x SD (") - 0.047 | |
LT (m) = 0.0351 x SD (") - 0.044 |
* The results above are approximate and may differ slightly from the actual measurements.
NOTE:
•See “Screen size and throw distance for 16:9 aspect ratio” on page 47.
•Do not use the projector at a raised or a horizontally tilted position as it may cause
malfunction of the projector.
•You can tilt the projector body approximately ± 30° vertically. Overtilting may result in 
shortening the component’s life.
•For the best quality of the projection image, install a screen where sun light or room light does not shine directly onto the screen. Close window shades or curtains to block the lights.
