| Matrox DualHead2Go is a combination of hardware and software that allows you to operate two screens from a single PC or laptop.With a two screen setup you can mirror (or clone) the image from your desktop onto both screens or you can extend your desktop over both screens. | ![]() |
In this post I’m going to show you how to extend your desktop over both screens.
1. Setup the hardware for Matrox DualHead2Go
Configure the hardware as shown below with the addition of the USB cable supplied.

2. Install the Matrox software
Place the installation disk into the PC and follow the on-screen instructions to install the Matrox software.
3. Configure Windows and Matrox software to extend the desktop
When you get to this stage you may find that your laptop is duplicating your desktop onto both screen rather than extending it. If this is the case do the following (If you are using a laptop keep the lid closed) :
Go to Windows Display Settings and configure as shown.

Go to the Matrox Powerdesk Settings and configure the Multi-display setup and desktop management settings as shown.


This should now extend your desktop over both screens.
Note : You may find that when you are configuring this some of the options above will not be shown or once you apply the settings they will not be maintained after a reboot. Not to worry I have discovered this is just a glitch in the hardware/software and it can be solved by pulling out the USB cable (which powers the Matrox device) and plugging it back in. Your settings should return to normal.
