Operation 19
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 1 adjuster foot. It
changes the image height and projection angle. To
adjust the projector, screw the adjuster foot to fine-
tune the horizontal angle.
To retract the foot, 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 corner of the screen for 3 seconds.
This function is only available when PC signal (analog RGB) is selected.
Fine-tuning the image size and clarity
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 quick-
release button as it is close to the
exhaust vent where hot air comes
from.
1. Adjust the projected image to the
size that you need using the zoom
ring. 2. Sharpen the image by rotating the
focus ring.
