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 dual display mode. Press the F7
(
) key to switch between video dual display and mirroring 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 an external
monitor.
Connecting an External Display or Projector
To connect an external display or projector to your computer with a DVI connection:
1
Turn on the external display or projector.
2
Connect the monitor cable to your PowerBook. Your PowerBook automatically detects the
external display.
3
Adjust the resolution on the external display by opening System Preferences, clicking
Displays, and clicking the Display tab (or use the Displays icon in the menu bar).
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 DVI-to-VGA adapter that came with your PowerBook to the external monitor or
projector’s VGA port.
3
Connect the DVI-to-VGA adapter to your PowerBook. Your PowerBook automatically detects
the external monitor.
4
Adjust the resolution on the external monitor or projector.
For information on the supported external monitor resolutions, see “External Monitor in
Dual Display or Video Mirroring Mode” on page 79.
Important
To ensure that your PowerBook automatically detects the external monitor
or projector, be sure the DVI-to-VGA adapter is plugged into the external monitor or
projector first.
Important
When using dual display or video mirroring with an external display connected
to your PowerBook, keep the PowerBook open at least 90 degrees to ensure proper air
circulation and heat dissipation over the keyboard.
