Projector Placement Guidelines
To get the best results when projecting your images, it is
important to position the projector at the proper height and
distance relative to the screen.
When projecting from a table or desk, place the projector so
the lens is aligned as closely as possible with the bottom of
your screen:
When projecting from the ceiling, align the lens as closely as
possible with the top of your screen:
Using the Keystone Feature
In circumstances where the lens cannot be properly aligned,
use the projector’s Keystone function to help maintain
optimum screen geometry.
❏ Press the Optical Keystone Adjustment knob on the side of
the projector (next to the handle). When the knob pops out,
turn it clockwise or counter-clockwise to move the lens up or
down. When you’re finished, press the knob back in.
❏ Adjust angle tilt digitally by pressing the Keystone button
on the control panel to increase or decrease the image
adjustment. This feature allows you to correct up to a ±20°
tilt, maintaining an aspect ratio of 4:3. Using the ELP Link
IV software, you can correct up to a ±30° tilt.
Calculating Image Size and Projection
Distance
The distance between the projector and the screen determines
the actual image size. To determine the exact distance required
for a particular image size (or to determine the size of an image
at a particular distance), use the formulas given in this section.
(The size of the image can also be changed by rotating the
zoom ring.)
Standard Lens Calculations
To determine the minimum and maximum diagonal size of an
image when you know the projection distance:
❏ Inches:
Maximum diagonal size = (0.642 × projection distance) + 2.197
Minimum diagonal size = (0.507 × projection distance) + 1.721
❏ Centimeters:
Maximum diagonal size = (1.630 × projection distance) + 5.5356
Minimum diagonal size = (1.287 × projection distance) + 4.3713
