53 Portable and Laptop Activation Chart NOTE: Often, pressing the key commands once activates the external video port, pressing it again activates both the external and internal ports, and pressing it a third time activates the internal por t. Refer to your computer’s doc- umentation for details on your spe- cific model. Many laptop computers do not automatically turn on their exter- nal video port when a secondary display device such as a projec- tor is connected. Activation commands for some laptop computers are listed in the following table. (If your computer is not listed or the given command does not work, refer to the com- puter ’s documentation for the appropriate command.) On some laptops, the activation function key is labeled with an icon, for example or the text CRT/LCD.

57 Using Video Mirroring with a PowerBook Computer When you turn video mirroring on (called SimulScan in newer PowerBooks-see below), the projector displays the same informa- tion that appears on your PowerBook’s built-in screen. When video mirroring is off, the projector acts like a separate display. To turn on video mirroring for the first time: 1Open the Monitors control panel; click on Monitor 2. 2Set the number of colors you want. 3Open the Control Strip; click on the monitor icon. 4Select “Turn Video Mirroring On.” Now you can turn video mirroring on and off from the Control Strip without having to open the Monitors control panel again. When using video mirroring and high color graphics such as slide shows, the projected image occasionally might turn black and white. If this happens, perform the following steps: 1Turn off video mirroring. 2Open the Monitors control panel. 3Move the white menu bar to Monitor 2 to set the projector as the primary monitor. 4Restart the PowerBook. Using SimulScan Some newer PowerBooks display images on an external monitor or projector differently than previous ones. When using SimulScan, the projector displays the same information that appears on your PowerBook To select SimulScan: 1Open the Control Panel, then double-click Monitors and Sound. 2In the Resolution list, choose the SimulScan mode, then click OK. 3If this changes your display settings, a dialog box appears. Click OK to confirm the change.
