Adjusting The Height; Auto-Adjusting The Image; Fine-Tuning The Image Size And Clarity - BenQ Commuter CP120 User Manual

Adjusting the height

The projector is equipped with one quick-release adjuster foot and one rear adjuster foot.
These adjusters change the image height and projection angle. To adjust the projector:
1. Lift the projector up and press the
adjuster button to release the
adjuster. The adjuster will drop into
position and be locked.
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 front adjuster button, then
slowly lower the projector. Screw the rear adjuster foot in a reverse direction.
If the screen and the projector are not perpendicular to each other, the projected image
becomes vertically trapezoidal. To correct this situation, adjust the value of Keystone in the
Picture menu, on the projector control panel, or on the remote control.

Auto-adjusting the image

In some cases, you may need to optimize the picture quality.
To do this, press Auto (or AUTO/CH.).
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 at the bottom right 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.
Refer to the screen size tables in
24 Using the projector
2. Then sharpen the image by rotating the
focus ring.
