Selecting the Extend my Windows desktop onto this monitor check box allows you to drag items across your screen onto alternate monitors. Or, you can resize a window to stretch it across more than one monitor.
To use the multiple monitor support feature, you need a PCI or AGP video adapter for each monitor. If you have an onboard video adapter (one that is not a plug-in card but is part of the motherboard) that you want to use as part of a multi-monitor configuration, it must be set as VGA. For more information about configuring multiple monitors, see the Windows 2000 Resource Kit.
The operating system always needs a VGA device. The computer’s basic input/output system (BIOS) detects the VGA device based on slot order, unless the BIOS offers an option for choosing which device is to be treated as the VGA device.
The VGA device cannot be stopped, which is an important consideration for docking units.
The monitor that is designated as the primary monitor will display the logon dialog box when you start your computer. In addition, most programs will display windows on the primary monitor when you initially open them.
Using the Matrox G400 Dualhead is a little different in Windows 2000. Because Win2K does not see it as separate devices, the two monitors are treated as one. So you stretch the desktop across both by choosing resolutions like 1600×600 or 2048×768 or 3200×1200. Yes, these resolutions are twice as wide as normal and the taskbar stretches across both monitors. Of course, you still have the big increase in desktop space.
So, hopefully you have just learned enough to set up and run multiple monitors on your computer. From experience I can tell you that I will never go back to a single monitor. The ability to work or surf on one monitor while checking email or chatting on the other is not to be missed. And for people who work in the graphics field, multi-monitor should be considered a necessity. Try it, you’ll like it!
