Dual-Monitor KVM for Four PCs

The Vszerda KM402C-USB3.0-CZY is a USB 3.0 KVM switch that lets one keyboard, one mouse and two HDMI monitors control four computers. It passes video at up to 4K 60 Hz with YUV 4:4:4 colour, HDCP 1.4 and HDR 2.2. Three extra USB 3.0 ports and audio/microphone jacks are shared across all connected systems. Built-in EDID emulators keep window layouts intact when switching.

Suited for multi-system desks, not single-PC users

This switch targets professionals who run four laptops or towers side by side and need instant access to dual displays and shared peripherals. Each computer must already support dual-video output for the extended, mirrored or spliced modes to work. Buyers with only one system, or whose machines lack a second video port, will not benefit from the dual-monitor capability.

Straightforward cabling, check your graphics first

Installation follows a five-step sequence: connect the 5 V power adapter, link both monitor HDMI cables to the KVM outputs, run paired HDMI and USB cables from each computer to the labelled input groups, then plug keyboard and mouse into the console ports. HDMI cables are not supplied. The only common issue is discovering a computer cannot drive two displays, which prevents the dual-monitor modes from functioning.

Questions about this item

What cables must I already have to connect four PCs to this KM402C-USB3.0-CZY switch?

You need eight HDMI cables for the dual-monitor inputs and four USB cables for the PC links; HDMI cables are not included.

Will my older 1080p monitors work with the 4K 60 Hz capability of this KVM?

Yes, the switch passes whatever resolution each monitor reports via its built-in EDID emulators, so 1080p displays function normally.

How can I verify the EDID emulation is keeping my window layout intact after switching PCs?

Switch between ports using the push button or wired remote; if windows stay in position without rearranging, the EDID simulation is active.
