- unit: mm (inch)
- L: Distance to screen
H: Height from the edge of screen to center of lens
- Illustrations show the projector installed using optional ceiling mount bracket ET-PKA110H.
This illustration is not drawn to scale.
- • All construction work should be done by a qualified technician.
- • When mounting to the ceiling, use the special mounting bracket. To prevent the projector from swaying or dropping, attach the wire that is included with the projector between the mounting bracket and the ceiling.
- • The value for H (the height from the edge of the screen to the centre of the lens) is the value when the horizontal optical axis shift function is not used. The value decreases when the horizontal optical axis shift function is used.
- • The value for L (distance to screen) varies slightly depending on the zoom lens characteristics.
- • At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
For a screen size different from the above, use the equation below to calculate the projection distance.
|Aspect ratio16 : 9||minimum
|L (m) = (diagonal screen size in inches) × 0.0292 - 0.054
L (m) = (diagonal screen size in inches) × 0.0583 - 0.041
- The accuracy of calculated value by the formula shown above is ±5%.
