Servers with dual video cards can be remotely accessed with an extended desktop configuration, which is available to remote users. This is done by creating dual port video groups.
Extended desktop configurations allow you to view the target server desktop across two monitors vs. the standard single monitor view.
Once a dual port video group is selected, all port channels in that group open simultaneously.
See Dual Port Video Configuration Steps
Review the information in this section for important information regarding dual port video groups.
Note: Dual port video groups are not supported by models with only one KVM channel such as KX3-108 and KX3-116 models.
