7 Make sure the other end of the monitor’s cable is attached to the monitor. Then attach the
end of the cable (with the monitor adapter, if you connected it) to the external monitor port
(™) on the back of the PowerBook.
If you are connecting a VGA or SVGA monitor, do not use the adapter. Connect the monitor
cable directly to the external monitor port on the PowerBook.
8 Turn on the external monitor.
9 Press the Power button (®) to turn on or wake your computer.
The external monitor is automatically activated.
10 Click the Resolution icon in the Control Strip and select a resolution from the menu that
appears.
If you select an external monitor resolution that matches the standard built-in resolution of
your PowerBook display, the same image will appear on both the display and the external
monitor (known as “simulscan” or “video mirroring”). If you choose a different resolution,
the PowerBook display will go dark and images will appear only on the external monitor. For
more information on the external monitor resolutions supported by your PowerBook, see
the
Technical Information booklet that came with your computer.

Important Video mirroring works only with the PowerBook display’s standard resolution.
For example, when the 12.1" display is set to its standard resolution (800 x 600) or the 14.1"
display is set to its standard resolution (1024 x 768), the display can mirror the external
monitor. However, if you switch the resolution to 640 x 480, the built-in display will go dark
because scaled resolutions cannot be used for video mirroring.
