The Black Box KVS4-2004HVX is a 4-port secure KVM switch for dual-monitor desks. It uses Flex Port connectors that accept either HDMI or DisplayPort, so one unit covers mixed-cable setups. It is built for government, defense and financial work where isolated networks must share a keyboard, mouse and two screens. Against consumer KVM switches it costs far more and adds strict port isolation and tamper protections, but it gives up USB-C and audio switching convenience.
