2.5 Dongles
About
Barco dongles are specially designed to allow Barco Display Controllers with a DisplayPort output to be
connected with a display with DVI input.
If video cable conversion is not required, you may bypass this section.
2.5.1 Passive Single-Link Dongle
Passive Single-Link
The passive Single-Link Dongle allows you to connect a display’s DVI input to the DisplayPort output of
your Barco Display Controller. It is compatible with all Barco grayscale displays and up to 2MP color
models. For color displays of 3MP and greater resolutions, the Dual-Link Dongle is necessary.
All Barco Display Controllers compatible with the DisplayPort interface come with a Sin-
gle-Link Dongle by default.

2.5.2 Active Single-Link Do ngle
Active Single-Link
Barco Display Controllers are not compatible with active single-link dongles. Please use the passive don-
gles that are included with your Barco Display Controllers.
2.5.3 Dual-Link Dongle
Dual-Link
The active Dual-Link Dongle converts DisplayPort input signals to dual-link DVI output signals. How-
ever, unlike the passive Single-Link dongle, the Dual-Link dongle allows higher resolutions (greater than
1920x1200) on color displays.
WARNING: A Dual-Link DVI cable must be used to connect your display’s DVI connector
with the DVI c onnector on the Dual-Link Dongle.
