Operation 28
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 1 quick-release adjuster foot and 1 rear adjuster foot. These
adjusters change the image height and projection angle. To adjust the projector:
1. Press the quick-release button and
lift the front of the projector. Once
the image is positioned where you
want it, release the quick-release
button to lock the foot in position.
Do not look into the lens while the lamp is
on. The strong light from the lamp may
cause damage to your eyes.
2. Screw the rear adjuster foot to fine
tune the horizontal angle.
To retract the foot, hold up the projector
while pressing the quick-release button, then slowly lower the projector. Screw the rear
adjuster foot in a reverse direction.
If the projector is not placed on a flat surface or the screen and the projector are not
perpendicular to each other, the projected image becomes trapezoidal. To correct this
situation, adjust the value of Keystone in the DISPLAY menu, on the projector control panel,
or remote control. See
"Correcting keystone" on page 29 for details.
Auto-adjusting the image
In some cases, you may need to optimize the
picture quality. To do this, press AUTO on the
projector or remote control. Within 3
seconds, the built-in Intelligent Auto
Adjustment function will re-adjust the values
of Frequency and Clock to provide the best
picture quality.
The current source information will be
displayed in the upper left corner of the screen
for 3 seconds.
The screen will be blank while AUTO is functioning.
Fine-tuning the image size and clarity
If needed, sharpen the picture by rotating the focus ring.
