Adjusting the projected image

Adjusting the projection angle

The projector is equipped with 1 quick-release adjuster foot and 1 rear adjuster foot. These 
adjusters change the image height and 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 

 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 clarity

If needed, sharpen the picture by rotating the focus ring.
