Matrox Graphics Card – User Guide
DualHead Multi-Display setup
If your Matrox graphics card has a second monitor connector (
see page 4
), you can enable a second
display (for example, a computer monitor or a TV) as part of your Windows desktop. This is the
Matrox DualHead Multi-Display feature. To use this feature:
Windows 98 –

DualHead
property sheet (
see “Accessing PowerDesk property
sheets”, page 6
).
2

option button.

OK
Æ
Yes
to restart your computer and for changes to take effect.

DualHead
property sheet (

5
Move the
Screen area
slider to adjust your display resolution and to select single-display
or DualHead Multi-Display mode. A DualHead Multi-Display resolution is twice as
wide or tall as its corresponding single-display resolution. For example, 640 × 480 is a
single-display resolution and 1280 × 480 is a DualHead Multi-Display resolution.
6
Click
OK
to accept your changes.
Note:
In DualHead Multi-Display mode under Windows 2000, Windows treats the main
and secondary displays as a single display (which the Matrox display driver divides between
two monitors). As a result, these displays always use the same resolution and color palette
settings. The resolution of both displays is limited by the display with the lower maximum
resolution.
