L: Distance to screen
E:Height from the edge of screen to center of lens
NOTE:
Illustrations show the projector installed using optional ceiling bracket.
This illustration is not drawn to scale.
*This distance is especially recommend- ed for
NOTE:
Values shown are approximate.
The value for L (distance to screen) varies slightly depending on the zoom lens characteristics.
When the shortest projection distance is used, a small amount of distortion may occur in the image due to the zoom lens characteristics.
Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 4 : 3 |
|
|
minimum | L (m) = (diagonal screen size in inches) x 0.0304 | - 0.0290 |
maximum | L (m) = (diagonal screen size in inches) x 0.0368 | - 0.0410 |
Aspect ratio 16 : 9 |
|
|
minimum | L (m) = (diagonal screen size in inches) x 0.0332 | - 0.0320 |
maximum | L (m) = (diagonal screen size in inches) x 0.0401 | - 0.0380 |
