Matrox Configuration

The Edge Blending module and the Multi-Screen module both require a Matrox DualHead2Go (DH2G) or TripleHead2Go (TH2G). We do not support any other hardware for these two modules.

We recommend downloading the latest software driver directly from Matrox’s website rather than installing the one on the CD. You can choose the version you need by clicking here.

The following instructions are only for the Digital Edition or DisplayPort Edition DH2G and TH2G. If your computer has a MiniDisplayPort or ThunderBolt connection, you must use the DisplayPort Edition.

Select EDID Management from the drop down list.

If you have not connected your Mac to your DH2G or TH2G, you will be guided through this process first. Once you have connected the hardware, you will see a screen like the one below.

The left side of the screen allows you to choose the display settings you need to use. Make those selections then click on the right arrow to add the resolution to the Active Resolutions and Refresh Rates list. If your resolution is already listed, you don’t need to make any changes. When you are done, click Apply Changes.

Refer to the Configuring your computer for first use section for instructions on selecting the resolution for your secondary display. You should have a high resolution that matches what you selected in the Matrox Control Panel. If you selected *3 800x600 60 Hz in the Matrox settings, you should have a resolution option of 2400 x 600 60 Hz** in the system display settings.

You will know you have properly configured your displays when you see the default desktop image spanning all three displays. If you do not see this, try restarting your computer and then going through the steps again.
