Both the digital and analog versions of the Matrox Dual/TripleHead2Go require a software installation. All drivers can be found here. The analog version will simply install additional standard 2 or 3 wide resolutions in your "Displays" control panel unders System Preference.
The digital version will install a System Preference which will appear as a control panel item (shown below). This allows you to easily establish which resolutions will appear in the Displays control panel.
Once the appropriate Matrox software is installed and resolutions are assigned (for digital versions), it will be time to choose the resolution desired for the secondary display. It's important to remember that the Mac thinks it's just one extra wide display - it has no idea this resolution will be broken down into multiple different outputs by the Matrox device.
When you open the Displays control panel, each display will have get it's own panel to configure them individually. There's always a designated primary display. This is where the menu bar with the Apple logo will always appear by default and is usually the internal display for any Mac with a built-in LCD (iMacs, MacBooks, etc.). Two other ways to tell which is the primary verse secondary panel are Macs with interal displays will have "Color LCD" in the title bar as well as having an "Arrangement" tab (pictured above).
ProPresenter Multi-Screen Module Configuration (continue):
3) Configure ProPresenter
Enter the Unlock Code for the module that was keyed for this system.
Then select the appropriate preference panel for the feature you need for configuration:
If you're trying to configure the 3 screen feature and your images do not span the three displays and/or your slides appear oddly shaped (tall and narrow), go to the "Display" preference and click on "Full Screen". Assuming your systems display preferences are set correctly above, ProPresenter will change it's resolution to match it (usually a triple wide setting of 1920x480, 2400x600, or the like).
