[. . . ] The projector will start to search for input signals. The current input source being scanned displays in the lower right corner of the screen. The search will continue until an input source signal is detected. You can also press SOURCE on the projector or remote control to select your desired input signal. For more information, refer to "Switching input signal" on page 31. 5. 6. If the frequency/ resolution of the input signal exceeds the projector's operating range, you will see the message "Out of Range" displayed on a blank screen. Please change to an input signal which is compatible with the projector's resolution. See "Timing chart" on page 58 for details. 30 Operation 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. The selected source name will display in the lower right corner of the screen for 3 seconds after each button press. 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 39 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). When switching between different signal inputs, you will need to adjust the ambient lighting conditions for the best picture quality. The input type affects the options available for the Preset Mode. See "Selecting a preset mode" on page 35 for details. Adjusting the projected image Adjusting the projection angle The projector is equipped with 2 quick-release adjuster feet and 2 rear adjuster feet. These adjusters change the image height and projection angle. Press the quick-release buttons and lift the front of the projector. Once the image is positioned where you want it, release the quick-release buttons to lock the front adjuster feet 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. [. . . ] Configure the computer's external display resolution to the projector's native resolution (1024 x 768 for PB8253/PB8263). If this option is not available, select one of the compatible listed in "Supported timing for PC (including DVI-I) input" on page 58. Check if your presentation files are created for a different resolution. The computer's external monitor setting is locked in 640 x 480. 4.
