Multi-Monitor Support Function of Newer Macintosh Notebook Computers
This bulletin provides configuration procedures for the newer Macintosh notebook computers
with the EPSON Multimedia Projectors.
Problem description:
When the projector is connected to an Apple notebook, part of the Mac OS desktop may not
display on either the LCD panel or the projector. Often, only the desktop wallpaper is visible on
one screen, with the other containing the complete video output.
Reason:
Newer Macintosh notebook computers are often configured for extended desktop video output
instead of video mirroring. This results in partial information being sent to either the LCD
panel or the projector. This feature has been observed on Powerbook and G3 Powerbook
models running Mac OS 8.x and later, but it is possible the issue has been experienced by
other Macintosh users.
Resolution:
1. Click the Apple Menu to select the Control Panels, Monitors and Sound option.
When the projector is powered on while connected to the computer, there will be an
“Arrange” icon in the Monitors and Sound control panel.
2. Click the “Arrange” icon to access that control. In the “Arrange” control view window, there
should be icons for two monitors.
3. Click one of the monitor icons and drag it on top of the other monitor icon. Release that
icon on the other icon. This enables dual display support where both screens receive and
display all video information.
