Adjusting The Projected Image - BenQ MX812ST User Manual

Adjusting the projected image

Adjusting the projection angle
The projector is equipped with 1 quick-release adjuster foot and 2 rear adjuster feet. 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 feet 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 feet
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 "Correcting keystone" on page 25
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.
• 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.
