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 

 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.

Fine-tuning the image clarity

Sharpen the image by rotating the focus ring.
