Switching input signal, Adjusting the projected image

Page 34 highlights

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. To cycle through the available input sources, press SOURCE on the projector or remote control. A source selection bar displays. 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 upper left 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 Auto Source Detection function in the SOURCE menu is activated if you want the projector to automatically search the signals. See "Auto Source Detection" on page 49 for details. The projector features PIP function which allows 2 different signals to be displayed at the same time. See "PIP (Picture In Picture) operation" on page 41 for details. 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 Application Mode. See "Selecting an application mode" on page 38 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. Press the quick-release button and lift the front of the projector. Once the image is positioned where you want it, release the quick-release button to lock the foot in position. 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 press the adjuster button as it is close to the exhaust vent where hot air comes from. 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 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, adjust the value of Keystone in the DISPLAY menu, on the projector control panel, or remote control. See "Correcting keystone" on page 35 for details. 34 Operation
