Notes:
1.
You can choose to wire either the VGA on the front panel or the optional DP++ port on the
rear panel.
2.
This is a DP/HDMI combo port. You can choose to have a DP++ port by request instead of
an HDMI port. However, make sure that you plug in an HDMI cable with the right orienta-
tion and alignment to avoid damage to the connector.
You should feel resistance (due to a
pin on the right) if the cable is not inserted correctly.
