NTI DP-HP-MNTR-SRC DisplayPort Hotplug Maintainer manages communication between a DisplayPort source device (e.g., computer) and sink device (e.g., monitor) with the purpose of maintaining the screen settings in the event of the sink device being disconnected. One application of this device is to resolve screen resetting issues when employing a DisplayPort KVM to actively switch between two sources and a single sink. By installing the DP-HP-MNTR-SRC in series with the source and KVM, the source will see a constantly connected sink and will therefore maintain the screen setting when the KVM user selects the other channel.
