Using an external monitor
You can connect an external monitor to your Macintosh PowerBook. If you
are familiar with other PowerBook models, you will note that the types of
monitors you can use with this model and the way images are displayed on an
external monitor differ somewhat from other PowerBook computers.
To m a ke th e b est choice of an external monitor, keep in mind the following
characteristics of your PowerBook’s hardware.
m Your PowerBook can support a variety of external monitors, including
17-inch and 20-inch multiple-scan displays. Resolutions supported range
from 512 x 384 pixels to 1024 x 768 pixels.
m The connector on the computer’s back panel is a VGA-style connector.
You can connect the cable for a VGA-style monitor directly to your
PowerBook.
m To connect an Apple (or Apple-compatible) monitor to your PowerBook,
you must use the adapter that came with the computer (part number
M0289).
m Images can appear on the internal display, the external monitor, or both
screens, depending on your choice of resolution on the external monitor.
m When an image appears on both screens, it is exactly the same (known as
“simulscan” or mirroring). You cannot move the pointer or menu bar from
one screen to the other (as you can when an external monitor is connected
to other PowerBook models or to most Macintosh desktop models).
m When an external monitor offers the same resolution as the PowerBook’s
internal display (800 x 600 pixels at 60 hertz [Hz] refresh rate), the image
appears on both screens the first time you turn on the computer (unless the
PowerBook’s display is closed).
m The PowerBook is designed to be “plug-and-play” when an external
monitor is attached. If the monitor is Apple-compatible, the PowerBook
tries to use the highest resolution possible. If the external monitor is not
Apple-compatible but provides a list of its capabilities, the system uses that
list of resolutions. If no list of resolutions is provided by the monitor, the
system uses a resolution of either 800 x 600 pixels or 640 x 480 pixels as
the default for that monitor.
