Adjusting the projected image

Adjusting the 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.
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
on page 21
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
