If not, change the projector's position so that the distance from the top of the projector lens to the top
of the image is less than the calculated value. For example, you may need to lower the projector or tilt
it down as shown:
Note
Consult a qualified projector specialist if you need to adjust your projector's position.
Sample Calculation
For example, if your projector is mounted 10 feet (3 m) away from the wall (distance
) for a 96-inch
c
WXGA image, the interactive module would be mounted 15.6 inches (396 mm) above the image area
(distance
), according to the table on page 9. The distance from the top of the projector lens to the
b
top of the image (
) might be 30 inches (762 mm). You would calculate the following:
a
15.6 –5.9 inches × 120/41.73 inches = 27.9 inches.
or 396 –150 mm × 3048/1060 mm = 709 mm.
The
distance (30 inches or 762 mm) is more than 27.9 inches (709 mm). You would need to lower
a
the projector by 2.1 inches (53 mm).
