Adjusting the projected image

Adjusting the projection angle

The projector is equipped with 2 quick-release adjuster feet. These adjusters change the picture height and projection angle.

To adjust the projector, slightly lift the front of the projector and press and hold the quick-release buttons on the both sides near bottom until the picture is positioned where you want it.

To retract the foot, hold up the front of the projector while pressing the quick-release buttons, then slowly lower the projector.

If the projector is not placed on a flat surface or the screen and the projector are not perpendicular to each other, the projected picture becomes trapezoidal. To correct this situation, see "Correcting keystone" on page 28 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.

The screen will be blank while AUTO is functioning.
