3.5 Connecting Display Devices/Screens
The controller can be customized to include up to 12 D4A (using multiple expansion chassis) modules,
enabling you to choose from a variety of configurations.
3.5.1 VGA Cables
When connecting display devices to the controller:
1. Connect the single end of each of the 2 dual VGA cables to the display module connectors on the rear
panel.
2. Connect the other 2 ends of each cable to your display devices. The way you connect these should reflect
how you want to number your display devices. By software default, display numbering begins from the
top-left of the display wall and continues across each row and down.

requires Extended Display Identification Data (EDID), which is detected at startup.
1. Connect the single end of each of the 2 dual DVI-D cables to the display module connectors on the rear
panel.
2. Connect the other 2 ends of each cable to your display devices. For more information about display
numbering, refer to 3.5.1 VGA Cables, on page 3-7 .
