You can also choose to play the slideshow on both screens. This is called video mirroring.
Note: Before you begin video mirroring or using a dual-monitor setup, attach the second
display or projector according to the instructions that came with the display or projector, and
the instructions that came with your computer (search online help for video mirroring,
displays, or dual monitors). You will not be able to do the setup until after the second display
or projector is attached.
Video Mirroring
After you have connected a second display or projector, you must configure your computer
for video mirroring. Some computers have video mirroring built-in. If yours does not, you
must configure it in the Displays pane of System Preferences.
To set up video mirroring:
1 Choose Apple (
) > System Preferences to open the System Preferences window.
2 In System Preferences, click Displays to open the Displays pane.
3 Set both displays to the same resolution and color depth.
4 Click the Arrange tab and select Mirror Displays.
To play your slideshow on a mirrored system:
1 Open the Keynote document by double-clicking its icon in the Finder.
2 Choose View > Play Slideshow (or click Play in the toolbar).
3 Press the Space bar or click the mouse to move to the next slide or to advance the object
build as the slideshow plays.
Note: Keynote generally plays back very smooth animations. However, since the two
displays used in a video mirroring configuration may have different refresh rates, one of the
screens may appear to “stutter.” This is because Keynote can only synchronize with the
refresh rate of one screen. PowerBooks and iBooks will display the smoothest animation on
the external display when they are in mirrored mode.
4 Press the Esc key or the Q key to end the show.
Both monitors display identical images.
Dual Monitors
With the dual-monitor configuration, you can play the slideshow on one screen, while
controlling the slideshow and viewing your notes on another display.
To set up dual monitors:
1 Choose Apple (
) > System Preferences to open the System Preferences window.
2 In System Preferences, click Displays to open the Displays pane.
3 Click the Arrange tab and follow the onscreen instructions.
