Hitachi CP-A100 Wall Mount Installation Guide
Step 1 Preparation
Reset all Keystones (Keystone = 0), Electrical Zoom settings (Zoom = 100), etc... prior to starting
adjustments.
Warm up the projector (30 minutes) in order to reduce image distortion.
Step 2 Horizontal Keystone
Adjust the Pitch (left-right angle)
and Rotation to eliminate horizontal
keystone effect. The left-right angle
affects the top line of the image;
the rotation affects the bottom line
of image. Ignore vertical keystone
during this process.
Step 3 Vertical Keystone
Optimize Focus and adjust Tilt Angle
to eliminate horizontal keystone
effect. The Focus adjustment will
change the vertical keystone.
If you cannot make both vertical
edges parallel, you may need to go
back Step2 and re-fine the Rotation.
Step 3 Horizontal Position
Adjust horizontal position so it is
centered on the display area.
Step 4 Image Size
Adjust throw distance to match the
length of top image with display area.
You may see some geometrical
distortions, so please do not try to fill
entire area. You may need to do fine-
tuning later (vertical and horizontal
keystone or image positions). Leave
a half inch margin.
Vertical Position
Step 4
Adjust vertical position so it is
centered in the display area.
