Adjusting the image
Adjusting the height
The projector is equipped with 1 quick-release adjuster foot and 2 rear adjuster feet. 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 feet to
fine tune the horizontal angle.
To retract the feet, hold up the projector while pressing the front adjuster button, then
slowly lower the projector. Scew the rear adjuster feet 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 on the control panel of
the projector or on the 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 at the
bottom right of the screen for 3 seconds, as below.
The screen will be blank while Auto is functioning.
Fine-tuning the image size and clarity
Refer to the screen size tables on page 14.
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.
