Adjusting the projected image
Adjusting the projection angle
The projector is equipped with an adjuster foot. It changes the image height and vertical
projection angle. Screw the adjuster foot to fine tune the angle until the image is positioned
where you want it.
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 23 for details.
Do not look into the lens while the lamp is on. The strong light from the lamp may cause
damage to your eyes.
Auto-adjusting the image
In some cases, you may need to optimize the picture quality. To do this, press Auto Sync on
the remote control. Within 5 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 display ViewSonic logo while auto adjustment is functioning.
This function is only available when PC D-Sub input signal (analog RGB) is selected.
