Configuring Multi-Monitor on Matrox Millennium G450 DualHead

Matrox Millennium G450 DualHead display card supports up to 2 monitors. It supports Multi-monitor Clone, Multi-monitor Span and True Multi-monitor modes. The True Multi-monitor mode is required for PowerShow (http://www.officeoneonline.com/powershow/powershow.html) as well as PowerPoint to recognize and utilize the multi-monitor capabilities of G450. We look at how to configure G450 for True Multi-monitor mode.

Configuring Matrox Millennium G450 DualHead for True Multi-monitor mode

  1. Connect monitors to both the display outputs of the video card.
  2. Go to Display Properties dialog box by selecting Start | Settings | Control Panel menu item and launching Display applet.
  3. Go to the Settings tab.


  4. You should see two monitors.
  5. Click on Advanced... button and go to DualHead tab.


  6. Select the DualHead Multi-Display item under the Features node.
  7. Click on Change Settings... button.


  8. Check the Use DualHead Multi-Display checkbox and select Separate resoltuions and color palettes for both displays option as shown above. This would make the display card switch to True Multi-monitor mode if it not already in that mode. As a side note, the other option that says Same resolution and color palette for both displays gets you in Multi-monitor Span mode.
  9. Click OK all the way to dismiss all the dialog boxes opened so far. Windows might require a reboot and would prompt you for it. It would reboot the machine and after the machine comes up again, it will be in True Multi-monitor mode.
  10. To enable use of the second monitor, go to the Display Properties dialog box and Settings tab again as in step 2 and 3.
  11. Click on monitor 2 and check against the Extend my Windows desktop onto this monitor check box as shown below.

     

In True Multi-monitor mode, you have both the monitors available for use. You can configure them to have different resolutions and color depths. Select the monitor in the Display Settings and set the Colors and Screen area individually.
