Our take on the Black Box KVS4-2004HVX Secure KVM Switch

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.

Questions and answers

What does Flex Port mean on this switch?
Each monitor input accepts either an HDMI or a DisplayPort cable, so you can mix connector types across your computers. You do not need separate adapters for each source.
Does it support USB-C laptops?
No. The switch has HDMI and DisplayPort inputs only, so a USB-C-only laptop needs a dock or adapter that outputs HDMI or DisplayPort.
Can it switch audio between computers?
No. This model handles video, keyboard and mouse only. Audio needs a separate switching path.
Is it compatible with standard keyboards and mice?
It is built for wired USB keyboards and mice. Some secure deployments require specific approved peripherals, so check your organization's list before buying.
How is it different from a regular 4-port KVM switch?
It adds strict isolation between ports and tamper-resistant design for classified or regulated environments. A consumer switch is smaller and cheaper but lacks those protections.
What is in the box?
The switch unit itself is the core item. Cables are typically sold separately, so plan for four computer connections and two monitor cables per computer.
Where is the Black Box KVS4-2004HVX Secure KVM Switch cheapest?
