Switching input signal
The projector can be connected to multiple devices at the same time. However, it can only
display one full screen at a time.
Be sure the Quick Auto Search function in the SOURCE menu is On (which is the default of
this projector) if you want the projector to automatically search for the signals.
You can also manually cycle through the available
input signals.
1. Press SOURCE on the projector or remote
control. A source selection bar displays.
2. Press / until your desired signal is
selected and press MODE/ENTER.
Once detected, the selected source information
will display on the screen for seconds. If there
is multiple equipment connected to the
projector, repeat steps 1-2 to search for another
signal.
The brightness level of the projected image will
change accordingly when you switch between
different input signals. Data (graphic) "PC"
presentations using mostly static images are generally brighter than "Video" using mostly
moving images (movies).
The input signal type effects the options available for the Picture Mode. See "Selecting a
picture mode" on page 27 for details.
The native display resolution of this projector is in a 4:3 aspect ratio. For best display
picture results, you should select and use an input signal which outputs at this resolution.
Any other resolutions will be scaled by the projector depending upon the 'aspect ratio'
setting, which may cause some image distortion or loss of picture clarity. See "Selecting
the aspect ratio" on page 26 for details.
Adjusting the projected image
Adjusting the image height
The projector is equipped with 1 adjuster foot. This adjuster changes the image height. To
adjust the projector:
1. Screw the adjuster foot to adjust the image
height.
To retract the foot, screw the 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
"Correcting keystone" on page 25 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.
Be careful when you screw the adjuster foot as it is close to the exhaust vent where hot air
comes from.
