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.
Be careful when you press the adjuster button as it is
close to the exhaust vent where hot air comes from.
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.
See "Correcting keystone" on page 20 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
1. Adjust the projected image to the
size that you need using the zoom
ring.
2. Then sharpen the image by rotating
the focus ring.
