Positioning the Projector
Follow these guidelines to get the best results when projecting:
❏ Place the projector on a sturdy, level surface, between
2.5 and 38 feet from the screen.
❏ Make sure there is plenty of space for ventilation around and
under the projector.
❏ Make sure the projector is within 10 feet of a grounded
electrical outlet or extension cord and within 5 feet of the
image source.
❏ Face the projector squarely toward the screen.
The projector supports 5 viewing setups, as shown below. If it is
installed in a rear or overhead position, you need to select the
correct
Projection option from the Setting menu after you turn
it on. If you mount the projector on the ceiling, professional
installation is recommended.
If the projector is tilted in the front or the back, you may need
to adjust the image shape. See page 5.
Image Size and Projection Distance
The distance between the projector and the screen determines
the size of the projected image, as shown below. Because other
adjustments—such as those made with the
Aspect button—
also affect the size of the image, the numbers shown in the
illustration should be considered as general guidelines, not exact
measurements.
Use the formulas given below either to find out how large your
image will be when you know the distance from the projector to
the screen, or to find out how far from the screen to place the
projector when you want an image of a certain size. Since the
size of the image can be changed by rotating the zoom ring,
formulas are given for both the minimum and maximum sizes.
To determine the diagonal size of an image when you know the
projection distance:
Minimum diagonal size = (0.39421 × projection distance) +
1.2116
Maximum diagonal size = (0.25690
× projection distance) +
0.69164
To determine the projection distance when you know the
diagonal size of the screen image:
Projection distance = (minimum diagonal screen size
×
2.5367) - 3.0735
Projection distance = (maximum diagonal screen size
×
3.8925) - 2.6922
