Take advantage of Matrox PowerDesk to fully benefit from your DualHead2Go Analog Edition adapter. PowerDesk enhances your PC or Mac computing experience and productivity with a vast array of customizable options. Now you can personalize your desktop to get the most out of your displays and make the most of your time.

PowerDesk for PC

Window Management:

Set the behavior of your apps, such as where windows should open up and maximize, or even on which display a PowerPoint slide show will run. You can view a presentation across multiple displays, or only on one depending upon your needs.

Desktop Divider:

Customize your desktop's layout and split it up into different sections. Either spread one application across your entire desktop or devote one display to each. Alternatively go even further and create multiple partitions on a single monitor and open an application in each section.

Mode Management:

Select the optimal multi-display settings for your setup, with regard to resolution and refresh rates.

Swap Displays:

Swap Displays spares you the hassle of reconnecting cables or physically moving around incorrectly hooked-up monitors. Switch your displays' on-screen content as a quick and easy troubleshooting fix.


Conveniently load your saved multi-display setup to accommodate ever-changing workplace needs or your personal preferences.

Keyboard Shortcuts:

Use a keyboard shortcut to quickly locate the mouse cursor or move your active window from one display to another; an easy way to access PowerDesk features.

Unattended Install:

Easily install Matrox PowerDesk across many systems without any user interaction — a must–have tool for any IT administrator for corporation-wide deployments.

PowerDesk for Mac

Swap Active Window and Maximize:

Efficiently organize your desktop at the press of a button by moving a given window from one display to the next and maximizing it to fit the entire screen.

Move Dock Position:

Further customize your Mac work space by moving the dock onto any of your screens.

Mode Management

Select the optimal multi-display settings for your setup, with regard to resolution and refresh rates.

Business Productivity

Working with more than one monitor allows you to see more, do more, and be more productive. Use the extra screen space to spread applications across your desktop, much like you would spread printed documents across your desk. For specialized applications, such as financial services or day trading programs, viewing data across multiple monitors provides the ability to see critical information at all times for quick decision making and streamlined workflow.

  • Fit more data on your desktop
  • Organize your applications and information as you wish
  • Easily multi-task without the need to toggle between applications
  • Compare documents side-by-side

Digital Signage

Drive two displays from a single player PC to create digital signage canvases of close to 3 million pixels. Unique in its ability to support two 1280x1024 monitors, the Matrox DualHead2Head2Go supports a variety of widescreen resolutions for the display of high-quality, uncompressed digital content across multiple monitors.

And if two displays aren't enough? Connect two DualHead2Go units to create a cost-effective, quad-screen setup. DualHead2Go units can be used to improve and simplify digital signage applications such as digital menu boards, terminal and concourse information displays, shopping mall kiosks, and ambience-enhancing installations—to name a few.

Media Creation & DCC

As an artist or digital content creator, you need multiple palettes, menus, bins, controls, and toolbars in your applications. Spread out your projects, work more comfortably, and increase your productivity with a Matrox DualHead2Go-powered multi-monitor setup. The extra screen space will allow you to view more layers of video on the timeline, increase the size of your video scopes and frame viewers, as well as customize your entire workspace to improve your workflow.

  • Maximize your studio real estate
  • Transform your laptop into a productivity powerhouse
  • Comfortably edit video content on your Mac notebook computer

CAD Design & GIS

Take advantage of increased desktop space when using CAD software. Work on your design drafts, architectural models, or plans across multiple monitors. Expand your perspective and arrange application windows so you can complete your work more quickly and efficiently. Add two monitors to your notebook computer for a full surround 3D design experience.
