Advanced Configuration
8 Choose Monitors in the Control Panel. Within the Monitors Setup
screen you will see two center squares. They represent the internal
display and the external monitor or projector. Each square has a
number. The number 1 represents the primary display and the number
2 represents the secondary display.
9 The primary display square (1) contains a small menu bar. Drag this
square to the secondary display square (2). You may also need to drag
the Happy Macintosh icon onto the desired monitor. To see the Happy
Macintosh icon, hold down the Option key while the Monitor’s Control
Panel is open. This change will switch the primary display (1), to the
secondary display (2), activating the external video port and sending
video to the projector.
Note: You may need to restart the Macintosh PowerBook for the changes
to take effect.

Macintosh
PowerBook 3400
and G3
The PowerBook 3400 and G3 have a standard DB9/15 VGA connector
built into the backplane for an external video monitor or projector. It is
capable of resolutions up to 1024x768. There is no Video Mirroring
Control Panel. The mode of display called Simulscan can only display
800x600 at 60Hz (refresh rate) simultaneously. If the external monitor
has any other resolution or refresh rate, the external monitor will be the
only display available.
Activating the
Laptop External
Video Port
Most laptop computers have a method for activating the VGA external
video port.
To activate the VGA port on IBM-compatible laptop personal computers,
use the function (Fn) key on the computer’s keyboard with one of the
regular function keys (for example, hold down the Fn key while pressing
F12). Some laptop computers need to be rebooted to allow the computer
to check for an attached external monitor, and then activate the external
port.
The following table describes, by computer manufacturer, how to activate
the external video port. Some manufacturers have several models that
require different activation methods; those methods are listed.
