Vszerda 3-Monitor 4-PC KVM Switch

This KVM switch connects four computers to three shared displays and four USB 3.0 peripherals. It supports both mirror and extended desktop modes for flexible multi-screen layouts. A wired remote and front-panel buttons give two ways to change the active system. The unit is built for users who need simultaneous access to multiple workstations.

Passive Operation at 5 Volts

The switch draws power from an included 12 V DC adapter but its internal logic runs at 5 V with no active cooling. No fan noise is generated during normal switching or video pass-through. Operating temperature is rated down to -5 °C for cool environments. Power consumption remains low because the device only routes signals rather than processing them.

Desktop Chassis With 21.2 in Width

The metal enclosure measures 21.2 in wide, 7.8 in deep and 4.5 in high, weighing 840 g. Twelve video ports — four HDMI 2.1 and eight DisplayPort 1.4 — plus four USB 3.0 Type-A ports face the rear for clean cable routing. Buyers whose laptops lack dual DisplayPort outputs cannot use the full three-monitor capability. The wired remote plugs into a dedicated front jack for convenient placement.

Questions about this item

How do I connect four computers to the three-monitor KVM, and which step is most often missed?

Each computer needs one HDMI and two DisplayPort outputs plus one USB link; the step most often missed is providing all three video cables per PC.

What maintenance or replacement will the KC-KVM403DH-US need over time?

The unit has no user-serviceable parts; only the four supplied USB 3.0 cables or the 12 V power adapter may need replacement if damaged.

What resolution or refresh-rate limit appears first during sustained 8K 60 Hz or 4K 144 Hz use?

The HDMI 2.1 and DisplayPort links cap video at 8K 60 Hz or 4K 144 Hz, while USB peripherals stay at 5 Gbps.
