48 Chapter 3
When an external monitor or television is connected, you can either have the same
image appear on both the internal display and the external monitor (known as video
mirroring) or use the external monitor to extend the size of the Mac OS desktop (known
as dual display mode). By default, your PowerBook starts up in video mirroring mode.
Press the F7 ( ) key to switch between video mirroring and dual display modes.
Note: Because of the display limitations of most televisions, images displayed on
the television screen will be of lower quality than those on the built-in display or
external monitor.
Connecting an External Display or Projector
To connect an external monitor or projector to your computer with a VGA connection:
1 Turn on the external monitor or projector.
2 Connect the Apple VGA Adapter that came with your PowerBook to the VGA port on the
external monitor or projector.
3 Connect the Apple VGA Adapter to your PowerBook. Your PowerBook automatically detects
the external monitor.
4 Use the Displays pane of System Preferences to adjust the resolution on the external monitor
or projector.
Important To ensure that your PowerBook automatically detects the external monitor
or projector, be sure the VGA adapter is plugged into the external monitor or projector first.
