4 Matrox Graphics Card – Installation Guide
Overview
Thank you for purchasing a Matrox graphics card. Your Matrox Productiva G100, Mystique G200
or Millennium G200 card is a high-performance graphics card that plugs into an expansion slot
inside your personal computer.
The Matrox graphics engine gives you superior performance with Windows, digital video and 3D
graphics. To accelerate 3D programs, your Matrox card uses bus mastering and has hardware-
accelerated features, including texture mapping, Gouraud shading and Z-buffering. Matrox G200
cards also support more advanced 3D features such as alpha-blending, anti-aliasing, MIP-
mapping, and more. Depending on the model of your Matrox card, it supports display resolutions
up to 1800 × 1440 and 1920 × 1200.
Your Matrox graphics card is 100% VGA compatible and supports all VESA standards: VBE 2.0
(Super VGA modes), DPMS (energy saving), and DDC-2B (Plug-and-Play monitor).

Matrox Graphics Card – Installation Guide 5
Hardware installation
1Switch to the standard VGA display driver
If you’re running Windows 95/98 on your computer, this step isn’t necessary. If you’re using
another operating system (for example, Windows NT 4.0), see its 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 your monitor or printer. Open the computer
and remove your existing graphics card. (If you have a display adapter built into your
computer’s motherboard, it should automatically disable itself after your Matrox card is
installed.)
3Choose an expansion slot
Most computers have different types of
expansion slots. Choose an AGP or PCI slot,
depending on the type of Matrox graphics
card you have. Your system manual should
identify the location of each type of
expansion slot in your computer.
WARNING – Static electricity can severely damage electronic parts. Take these precautions:
Before touching any electronic parts, drain the static electricity from your body. You can do
this by touching the metal frame of your computer.
Don’t remove a card from the anti-static container it was shipped in until you’re ready to
install it. When you remove a card from your computer, place it back in its container.
When handling a card, hold it by its edges, and avoid touching its circuitry.

Remove the cover for the slot you intend to
use. Save the screw for the mounting bracket.
Position your Matrox card over the expansion
slotyou’vechosen.Pushthecardinfirmlyand
evenly until it’s fully seated in the slot.
Replace the screw to secure the bracket of
your Matrox card to the computer frame.
5Connect the monitor
Simply plug your monitor cable into the
monitorconnectoronyour Matrox card. Make
sure the other end of the monitor cable is
properly connected to your monitor. See your
monitor manual for more information.

6If your Matrox card
supports TV output:
Connect a TV or VCR (optional)
If your Matrox graphics card has extra video
connectors on its bracket, you can use them to
view or record the display of your computer
with a TV or VCR.
If your video device (TV or VCR) didn’t come
with composite video (RCA) or S-video
cables, this type of cable is available at most
electronics stores. The type you use depends
on what your video device (TV or VCR)
supports. Many video devices support
composite video connections, and some
higher-quality video devices support S-video
connections.
Attach one end of your composite video or
S-video cable to the appropriate connector on
your Matrox card. Attach the other end to the
VIDEO IN* connector on your TV† or VCR.
Before viewing or recording video output
directly from your computer, make sure your
TV or VCR is set up to use line input. For
example, if your TV has a TV/VIDEO switch,
set it to VIDEO; or if your VCR has a
TUNER/LINE switch, set it to LINE.
Optionally,ifyou use the compositevideo and
S-video connectors on your Matrox card, you
can directly connect two different video
devices at the same time.
To view and record output from the same
Matrox video connector, you can connect it to
aVCRandconnecttheVCRtoaTV.For more
information, see your VCR and TV manuals.
* The labels on your devices may not be consistent with what’s in this guide. Different manufacturers sometimes use
different labels for the same type of controls and connectors. For example, the VIDEO IN connector on your TV
may be labeled VIDEO 1 (or VIDEO 2). To match labels, see the documentation for your video devices.
† If your TV only has an antenna or cable TV connector, you can use an RF modulator to connect it to your Matrox
card. RF modulators are available at most electronics stores.

8 Matrox Graphics Card – Installation Guide
Sound output Typically, the sound
output from a computer comes from speakers
connected to your sound card. If you prefer,
you can hear or record the sound output from
yourcomputerusingthe same TV or VCR you
connect to your graphics card. To do this, you
need an audio cable with a stereo jack on one
end, and two RCA connectors on the other
end. If you don’t have this type of cable, you
can buy one at most consumer electronics
stores.
Plugthestereo-jackendof the audio cableinto
the LINE OUT* connector on your sound card.
Plug the other end of the cable into the left (L)
and right (R) AUDIO IN connectors of your
video device. For more information, see your
sound card manual.
SCART adapter Some video devices in
Europe only have SCART connectors. This
type of connector includes video and audio,
whereas composite video or S-video
connectors include only video.
If your TV or VCR only uses a SCART
connector, you need a SCARTcableadapterto
connect your computer to that TV or VCR. If
you don’t already have a SCART adapter, you
shouldbeableto purchase one from your local
electronics store. You need a SCART adapter
with 3 female connectors – 2 audio and
1 video. There are different SCART adapters
for composite video and S-video. If you’re not
sure which your TV or VCR supports, see its
manual.
* If your sound card has no LINE OUT connector, you can use its SPKR connector instead. In this case, all your
computer’s sound output goes to the video device you connected to.

To use a SCART adapter, connect the SCART end of the adapter to your TV or VCR, then
connect the other end to your Matrox card and sound card.
For a TV with separate lines for red, green and blue video signals, a special SCART adapter is
available. For more information on this special adapter, see the Matrox Web site
(www.matrox.com/mga).

Troubleshooting
This section contains solutions to problems you may encounter with your Matrox graphics card.
Problem Computer doesn’t boot after Matrox card is installed
Cause There may be another graphics adapter in your computer. (For Matrox multi-
display mode in Windows NT, all other graphics cards in your computer must also
be Matrox cards of the same model.)
Solution If another graphics card is plugged into an expansion slot, remove it.
Solution If a graphics adapter is built-in to your computer’s motherboard, your system may
have not automatically disabled it when you inserted your Matrox card. Check your
system manual for instructions on how to disable your computer’s built-in graphics
adapter.
Problem Wrong color balance, screen image off-center, or no picture at all
Cause Your monitor’s video controls may be improperly set.
Solution Adjust your monitor’s controls (brightness, contrast and so on). For more
information, see your monitor manual.
Cause Your monitor may not be properly connected.
Solution Make sure the monitor’s power cable is firmly in place.
Solution Make sure the 15-pin connector to your Matrox graphics card
is firmly in place.
Solution If your monitor uses a 15-pin connector, make sure the
connection to the monitor is firmly in place.
For a list of notes, problems and limitations, click Programs Matrox PowerDesk 

your monitor.
Problem After the startup screen, or after display settings are changed,
the screen image is garbled or unusable
(rolling screen images, overlapping screen images
or a blank screen)
Cause The Matrox display driver may be trying to use settings your monitor doesn’t
support. This can happen if a monitor was never selected in the software and the
display resolution was changed to one your monitor doesn’t support, or if the
monitor connected to your computer was changed without it being changed in the
software.

on a computer that makes a distinction between bus mastering and slave slots.
Solution Change slots. Shut down your computer, disconnect it from the power supply,
remove your Matrox card and then insert it into a different PCI expansion slot. For
instructions on how to safely install your Matrox card, see “Hardware installation”,
page 5.
Cause Your computer may have not given an interrupt request (IRQ) to your Matrox
graphics card or may have given one used by another device in your computer. This
may be because your computer’s “Plug-and-Play” feature is turned off.
To check the display adapter’s IRQ (Windows 95/98):
1Right-click the My Computer icon on the Windows desktop background, then
click the Properties menu item Device Manager tab.
2Click the plus sign to the left of the Display adapters. An “X” through an icon
means the hardware has been disabled. A circled exclamation point through the
icon means the hardware has a problem.
