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 

 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. 

Fine-tuning the image size and clarity

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.
