Adjusting The Projected Image - ViewSonic PJD7383 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 28
• Do not look into the lens while the lamp is on.
The strong light from the lamp may cause
damage to your eyes.
• Be careful when you press the adjuster button
as it is close to the exhaust vent where hot air
comes from.
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 upper left 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.
