Vszerda KC401ADZUS 4-port HDMI 2.0 KVM switch USB 3.0 4K@60Hz

Four-Computer KVM Switch

The Vszerda KC401ADZUS lets four HDMI computers share one monitor, keyboard and mouse through a single push-button selector. It targets office workers and multi-system operators who want to eliminate duplicate peripherals and reclaim desk space. The metal chassis houses four HDMI 2.0 inputs and four USB 3.0 ports for peripheral sharing. No external power adapter is required; the unit draws power from the connected USB cables.

4K@60Hz and USB 3.0 Headroom

Each input supports up to 4K resolution at 60 Hz with 18 Gbps bandwidth and 4:4:4 chroma sampling when an HDMI 2.0 cable is used. The supplied cable is HDMI 1.4 and may limit the maximum refresh rate. USB 3.0 ports provide faster, more stable data transfer for drives, printers, scanners and webcams compared with the USB 2.0 switches commonly found on the market. EDID emulators on every input keep display information consistent when switching between computers.

Upgrade From Two-Port or USB 2.0 Switches

Users moving from a two-port KVM gain capacity for two additional systems without adding a second switch. Builders replacing a USB 2.0 model benefit from the higher peripheral bandwidth needed for modern external storage and high-resolution webcams. The jump is worthwhile when the workflow demands four live computers and USB 3.0 peripheral speeds; it is not suited for setups that only ever use one or two sources or that rely on PS4 mouse and keyboard control, which this device does not support.
