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 43 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 31 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 29 for details.
