Quick hardware installation
1Switch to the standard VGA driver
If you’re running Windows 95 on your computer, this is not necessary. If you’re running
Windows 3.1, Windows NT or OS/2, refer to your operating system’s documentation for how
to switch to VGA mode.
2Open your computer and remove your existing graphics card
Turn off your computer and all peripherals such as the monitor or printer. Once open, remove
your existing graphics card. (If you have a display adapter built into your computer’s
motherboard, it should automatically disable itself after your Millennium card is installed.)
3Choose a PCI expansion slot
Most PCI bus computers contain a combination of PCI and ISA expansion slots. PCI slots are
usually made with plastic of a contrasting beige color, and are shorter than other slots in your
computer. Your system manual should identify the PCI slots. Plugging your Millennium card
into a non-PCI slot could damage the card, your computer, or both.
Warning!
Static electricity can severely damage electronic components. To be safe, take the following
precautions to ground yourself before touching your Millennium card:
1Turn off the power to all equipment, leaving it plugged in.
2Touch the metal chassis of your computer to drain the static electricity from your body
before you touch the card. Don’t let your clothes touch any of the components.

Microsoft®DirectX™
MGA PowerDesk for Windows 95 supports DirectDraw, DirectVideo and Direct3D. These
interfaces (and others such as DirectSound and DirectInput) are collectively referred to as DirectX.
DirectX was developed by Microsoft so that programs could support advanced hardware features
without being written specifically for each hardware model. Programs that use DirectX use the
Microsoft DirectX interface, which in turn uses the MGA DirectDraw driver, which supports
DirectVideoandDirect3D.TheDirectXinterfaceisintheformofDynamicLinkLibrary(DLL)files.
DirectX installation required!
TheMicrosoftDirectXinterfacemustbeinstalledtoensurethatprogramsthatuseDirectXfunction
correctly and so these programs can benefit from Matrox hardware acceleration. Many programs
install DirectX as part of their installation procedure. Check the Display Properties dialog box Æ
MGA Settings tab ÆAdvanced button ÆInformation tab ÆMicrosoft DirectX Version label to see if
Microsoft DirectX is present, and if it is, to see the version number. To install Microsoft DirectX:
1Insert the Matrox CD-ROM in your CD-ROM drive.
(Windows 95’s autorun feature will start the mgasetup program.)
2Click on Microsoft DirectX list item ÆInstall button ÆNext button to begin installation.
3Click on Reboot to restart your computer and for the changes to take effect.
Depending on the version of Microsoft DirectX on your CD-ROM, you may have to install
Microsoft DirectVideo separately. If it appears in the mgasetup list, install it as well.
Direct3D limitations
The Matrox Millennium is a high performance graphics card that provides acceleration for 3D
rendering in hardware. The Millennium accelerates 3D operations such as flat and Gouraud shading,
Z-buffering,andcolorditheringinhardware.However,theMillenniumdoesnotprovide full support
for 3D texture mapping in hardware. As a result, programs that require the use of texture mapping
and other more complex 3D functions will use the Millennium’s fast 2D acceleration, and your
computer’s CPU will perform rendering.
Programs that require only those 3D features supported by Millennium – including many CAD
and multimedia programs – will be fully 3D accelerated in hardware by the Millennium.

Matrox Millennium Installation Guide 11
Windows 3.1 software
The Windows 3.1 product contains drivers, MGA PowerDesk utilities, a monitor file, a Screen
Saver and a DCI driver, as well as DynaView 2D and 3D for Windows.
Installation
1Start Windows in VGA resolution and put the Matrox CD-ROM in drive d:. Select File Æ
Run in Program Manager. Type d:\win31\setup in the Command Line box.
2You will be prompted for the products to install: Windows Drivers and PowerDesk

If you select DynaView for Windows, you will be prompted for the specific products to
install: DynaView 2D for Rel. 12, DynaView 3D for Rel. 13 and/or DynaView 3D.
3Once you have selected what you want to install, the installation program will prompt you
for the various paths in which to install each product. Next, the MGA software installation
program will run (bar graphs indicate the progress of the installation). A new Windows
group called MGA PowerDesk will be created.
Select a monitor
4If this is a first time-installation, the Monitor Selection program will ask you to select an
appropriate monitor. If your monitor is Plug-and-Play (VESA DDC-compliant), you won’t
have to specify a monitor; otherwise, please select one at this point to prevent the driver
from starting up in a resolution not supported by your monitor. The Monitor Selection
program is explained in its Help file (click on the Help button in the program).
If you are updating one of our older drivers, then the Monitor Selection program will not
start, but the installation program will ask you if you wish to keep your present mga.mon
file,incaseyouhavecustomizedthefileforaparticularmonitor.Ifyouhavenotcustomized
the mga.mon file, click on YES to overwrite it with the new version.
Select a start-up mode
5Next you must select a start-up display mode for Windows. The range of resolutions and
colors available to you is limited by the amount of RAM on your Millennium card. Choose
