Switching input signal
The projector can be connected to multiple devices at the same time. However, it can only
display one at a time.
When SOURCE on the projector control panel or the remote control is pressed, information
of current signal and resolution will display at the lower right corner. Press SOURCE again
to display a source selection bar. You can manually press SOURCE repeatedly until your
desired signal is selected or let the projector automatically search for the available signal.
Once detected, the selected source information
will display at the lower right corner of the
screen for 3 seconds. If there is multiple
equipment connected to the projector, you can
press the button again to search for another
signal.
Be sure the Source Scan function in the
Advanced menu is activated if you want the
projector to automatically search the signals. See
"Source Scan (on)" on page 41 for details.
If no input is detected after auto searching for
two rounds, a message of "No Signal" will be
shown on the screen.
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 type affects the options available for the Application Mode. See "Selecting a picture
mode" on page 29 for details.
Adjusting the projected image
Adjusting the projection angle
The projector is equipped with 1 quick-release adjuster foot and 1 rear adjuster foot. These
adjusters change the image height and projection angle. To adjust the projector:
1. Lift the projector up and press the
adjuster button to release the
adjuster. The adjuster will drop
into position and be locked.
Do not look into the lens while the lamp is
on. The strong light from the lamp may
cause damage to your eyes.
2. Screw the rear adjuster foot 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 foot in a reverse direction.
If the screen and the projector are not perpendicular to each other, the projected image
becomes vertically trapezoidal. To correct this situation, adjust the value of Keystone in the
Picture menu, on the projector control panel, or on the remote control. See "Correcting
keystone" on page 27 for details.
