Matrox DualHead2Go is a VGA video splitter box to allow 2 displays to be connected to the system. The way it provides this capability is to tell Windows that there is only one monitor but with a dimension of twice the normal monitor width. The
Matrox DualHead2Go box splits the display content across two outputs on its own. This clever technique requires only one input but can output different content through different displays.

To show multiple slide shows simultaneously through Matrox DualHead2Go, we will use the TickerShow feature of OfficeOne PowerShow. The TickerShow feature allows multiple slide shows to be displayed simultaneously on the same monitor. It requires a Layout presentation that specifies the position and dimensions of the slide shows on the monitor. For DualHead2Go's twice-width monitor, we would use the layout presentation available here (layout_dualhead2go.ppt). The layout presentation specifies two presentations Pres1.ppt and Pres2.ppt. Each of these presentation covers different halves of the twice-width monitor. Effectively, this makes each presentation appear fully on a monitor.

Following are step-by-step instructions:

1. Open Pres1.ppt, Pres2.ppt and layout_dualhead2go.ppt in PowerPoint.
2. Select Slide Show | Ticker Show item.
3. Select the monitor 2 as it is the one that has DualHead2Go attached to it.
4. Select layout_dualhead2go.ppt in TickerShow Layout Presentation box.
5. Click Start Show button.

This will start Pres1.ppt on one monitor and Pres2.ppt on second monitor of Matrox DualHead2Go.
