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.

This function is only available when PC signal (analog RGB) is selected.
