Boxlight CD-455m ユーザーズマニュアル

When you turn video mirroring (called SimulScan in newer Pow-
erBooks—see below) on, 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:

Open the Monitors control panel; click on Monitor 2.

Set the number of colors you want.

Open the Control Strip, then click on the monitor icon.

Select “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:

Turn off video mirroring.

Open the Monitors control panel.

Move the white menu bar to Monitor 2 to set the projector as 
the primary monitor.

Restart the PowerBook.

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:

Open the Control Panel, then double-click Monitors and 

Sound. 

In the Resolution list, choose the SimulScan mode, then click 
OK.

If this changes your display settings, a dialog box appears. 
Click OK to confirm the change.
