DisplayPort Connector (GPU & COM Express Output)
With the addition of on-board DisplayPort-HDMI/DVI switching circuitry, the VXG/DXG can interface with
most monitors available. Please see the DisplayPort-HDMI/DVI switching description for details.
Two Disp+ connections from the COM Express module are available and can be configured to output
DisplayPort, or HDMI/DVI through the use of the appropriate cable. The configuration of each interface is
setup via the COM Express module’s BIOS settings. Refer to the COM Express module’s documentation for
more details.
Up to an additional four Disp+ from the GPU are also available and can be configured to output
DisplayPort, or HDMI/DVI through the use of the appropriate cable. Please refer to the GPU Summary for
more details on GPU Outputs.

DisplayPort-HDMI/DVI Switching
The
VXG/DXG Systems Disp+ connectors can be used to display outputs other than DisplayPort.
On-board switching circuitry to enable HDMI or DVI has been included. The VXG/DXG COM Express
DisplayPort Connectors may require a change to the COM Express BIOS to swap output formats. However the
GPU DisplayPort Connectors are Hot Swappable and require only a cable change.
