Adjusting The Projected Image - Hitachi CP-DX351 User Manual

Adjusting the projected image

Adjusting the projection angle
The projector is equipped with two adjuster feet.
They change the image height and vertical
projection angle. Screw the adjuster feet 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
details.
CAUTION
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 screw the front adjuster foot 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
remote control or activate the Auto Adjustment function in the SOURCE menu. 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 computer signal (analog RGB) is selected.
Fine-tuning the image clarity
1. Adjust the projected image to
the size that you need using the
zoom ring.
2. If necessary, sharpen the image
by rotating the focus ring.
