Matrox Graphics Card – User Guide 7
Determining your main and secondary display
Your Matrox hardware has a main display and a secondary
display – the main display is more capable than the
secondary display. Which connector the software uses for
your main display depends on your connection setup.
!
If your Matrox card has two HD-15 connectors or if you’re connecting your monitors
using a dual-monitor cable,
the connectors are numbered. The main display uses the
connector labeled
1
and the secondary display uses the connector labeled
2
.
!
If your Matrox card only has one connector and you’re not using a dual-monitor cable,
this connector is used for your main display.
!
If your Matrox card has a DVI and an HD-15 connector,
there are 3 conditions that
determine which connector is used for your main display:
"
If a digital monitor is connected, the DVI connector is used for your main display.
"
If the TV output adapter is connected, the DVI connector is used for your main
display.
"
If no digital monitor or no TV output adapter is connected, the HD-15 connector is
used for your main display.
