BenQ Digital Projector LX60ST - Manual (Page 21)

Operation 21
Adjusting the projected image
Adjusting the projection angle
The projector is equipped 2 adjuster feet. These adjusters change the image height and
projection angle. To adjust the projector:
Screw the adjuster feet to fine-tune the
horizontal angle.
To retract the feet, screw the adjuster feet 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 22
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 clarity
Sharpen the image by rotating the focus ring.
Do not look into the lens while the
light source is on. The strong light
from the light source 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.
