Hardware installation

This section describes how to install your Matrox card. If your Matrox graphics card is already

installed in your computer, skip to “Connection setup”, page 4. For information specific to your

computer, like how to remove its cover, see your system manual.

1 Open 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 any). (If graphics hardware

is built into the motherboard of your

computer, this graphics hardware should

automatically disable itself after your

Matrox card is installed.)

2 Locate the AGP slot in your

computer

Most computers have different types of

expansion slots. Your Matrox graphics card

is an AGP card. Locate the AGP slot in your

computer. Your system manual should

identify the location of each type of

expansion slot in your computer.

WA RNIN G :

To avoid personal injury, turn off your computer, unplug it, and then wait for

it to cool before you touch any of its internal parts. Also, static electricity can severely

damage electronic parts. Before touching any electronic parts, drain static electricity from

your body (for example, by touching the metal frame of your computer). When handling

a card, carefully hold it by its edges and avoid touching its circuitry.

* With multi-display mode, you may be able to use your existing graphics card. For more information, see Windows online help

under “Multiple Display Support”.

Connection setup

This section describes how to connect your monitors to your Matrox graphics card.

Connector overview

*

* Matrox Millennium P650 products include 2 DVI-to-HD15 adapters, but no dual-monitor cable or TV output adapter.

Note:

To c o n n e c t a

digital

monitor (a

monitor that uses digital input, usually a

flat panel monitor) to your Matrox

product, your monitor must have a DVI

connector.

If you have an

analog

monitor (a monitor

that uses analog input) with a DVI

connector and you want to connect it to

an HD-15 connector, you’ll need a separate adapter. If this adapter isn’t included with your

monitor, contact your monitor vendor.

Some monitors with DVI connectors support both digital and analog input. If you’re using

one of these monitors with your Matrox product, make sure it’s configured to use the

correct type of input. For more information, see your monitor documentation.

3 Connect video output

To connect to a TV or a video recorder,

you’ll need a composite video (RCA) or

S-video cable.

If your video device (a TV or a video

recorder) didn’t come with one of these

cables, these types of cable are available at

most electronics stores. The type of cable

you use depends on what your video device

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 TV

adapter.

b

Attach the other end to the

VIDEO IN

*

connector on your TV

†

or video

recorder.

c

Before viewing or recording video

output directly from your computer,

make sure your TV or video recorder is

set up to use

line

input. For example, if

your TV has a

TV/VIDEO

switch, set it

to

VIDEO

; or if your video recorder has

a

TUNER/LINE

switch, set it to

LINE

.

Optionally, if you use the composite video

and

S-video connectors on your Matrox TV

adapter, you can directly connect two different video devices at the same time.

To v i e w

and

record output from the same Matrox video connector, you can connect it to a

video recorder and connect the video recorder to a TV. For more information, see your video

recorder 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

4 Connect audio 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 your

computer using the same TV or video

recorder 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.

a

Plug the stereo-jack end of the audio

cable into the

connectors of your video device. For

more information, see your sound card

manual.

Software setup

If a TV or video recorder is connected to your Matrox product, you can use TV output mode to view

or record your display on your TV or video recorder. (To connect video devices to your computer, see

page 14.)

TV settings have lower resolutions and refresh rates than typical computer monitor settings. Lower

refresh rates may result in more noticeable flicker.

* If your computer has no audio

LINE OUT

connector, you can use its

SPKR

(speaker) connector instead. In this case, all your

computer sound output goes to the video device you connected to.

Solution

Change settings in your computer BIOS setup utility.

If your computer has the options of enabling Plug-and-Play detection, or assigning an IRQ

to a VGA adapter, make sure they’re enabled. If your computer doesn’t have these options,

you may be able to manually assign an IRQ to your graphics card using the BIOS setup utility.

For more information on the BIOS setup utility of your computer, see your system manual

or contact your system manufacturer.
