Firmware restricts video output to a single active monitor at a time despite the four physical video connectors. The dock subtracts a mandatory 15W reserve from the incoming power budget — an undersized wall charger will trigger "slow charging" BIOS alerts on enterprise laptops. USB-A and USB-C data ports do not support Fast Role Swap (FRS); only the network and video links are protected.
