Matrox Electronic Systems DVI G450 Multi-display mode, displays aren’t numbered consecutively

Solution	Install the latest unified display driver for your Matrox graphics cards. (A unified display
	driver supports more than one model of graphics card.) This driver is available on the Matrox
	Web site (www.matrox.com/mga). Make sure that the display driver supports all Matrox
	products in your computer. Install the display driver by running the setup program included
	with it.
	Note: If your Matrox product was provided by the manufacturer of your computer, check the
	Web site of that manufacturer for the latest display driver. A display driver provided by the
	manufacturer of your computer is more likely to be tested with your computer model.
	Note: A unified Matrox display driver may not be available for all the models of Matrox
	graphics cards installed in your computer (especially for older models). Under Windows
	98/Me/2000/XP you can use more than one display driver in this case.
Solution
	If a graphics card isn’t supported, you may need to remove it. If there’s a graphics processor
	built into the motherboard of your computer that’s not supported by your software, see your
	system manual for information on how to disable this graphics processor.
Cause	Windows 98/Me/2000/XP – If the Windows method for display driver installation was used
	(instead of running the setup program included with your Matrox display driver), the driver
	may not be installed for all the graphics cards it supports.
Solution	Run the setup program included with the Matrox display driver. The setup program
	automatically installs the display driver for each Matrox graphics card it supports.
Problem	In multi-display mode, displays aren’t numbered consecutively
Cause	If you have more than one graphics card in your computer, the
	display numbering may not be consecutive for the displays of a
	multiple-display card (for example, a DualHead supporting
	card). Display numbering depends on the types of expansion slots used in your computer
	(AGP and PCI) and the BIOS settings of your computer.
Solution	Windows* 98/Me/2000/XP – Move the displays in Windows.
	(* Windows 2000/XP – In “Separate resolutions…” mode only.)
	1 Right-click your Windows desktop background, then click Properties # Settings.
