Matrox Electronic Systems LX G450, LE G450 manual Determining your main and secondary display

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.
