See page 24, "Computer Mode Memory Adjustments" for details. • This projector may not be able to display images from notebook computers in simultaneous (CRT/LCD) mode. If this occurs, turn off the LCD display on the notebook computer and output the display data in "CRT only" mode. Details on how to change display modes can be found in your notebook computer's operation manual. E-18

Notes:
•
When connecting a notebook computer to the data-projector for display on a (800
×
600) LCD screen, the screen may not
show a full picture image. See page 24, “Computer Mode Memory Adjustments” for details.
•
This projector may not be able to display images from notebook computers in simultaneous (CRT/LCD) mode. If this occurs,
turn off the LCD display on the notebook computer and output the display data in “CRT only” mode. Details on how to change
display modes can be found in your notebook computer’s operation manual.
