Vszerda KM402B 4-Port Dual-Monitor KVM

This Vszerda KM402B KVM switch lets one keyboard, mouse and two HDMI monitors control four computers or laptops. It supports 4K resolution at 60 Hz when both the source graphics card and the display support that mode. EDID emulation on every input port keeps window layouts stable during switching. Three USB 3.0 ports and separate audio and microphone connections are provided for shared peripherals.

Upgrading from single-monitor or two-port KVMs

The unit replaces a single-head KVM or a two-port switch when a second monitor and two extra computers must share the same desk. The jump is worthwhile when workflow demands simultaneous dual-screen viewing across four systems without rearranging windows after each swap. It does not suit users who only need one display or who have fewer than three computers to manage.

Installation and common issues

Connect the 5 V power adapter, then link each computer with one USB cable and two HDMI cables (cables not included). Plug keyboard, mouse, monitors, audio and microphone into the console ports. Switch between systems using the rocker button on the unit. The most frequent problem is missing 4K 60 Hz output because either the GPU or the monitor does not support that resolution.

Questions about this item

What are the physical dimensions and weight of the KM402B-USB3.0-CZY KVM switch?

The unit measures 2.0 in x 1.0 in x 3.0 in and weighs 0.87 kilograms, so it fits easily on a desktop or shelf.

How do I connect the four computers and what is the common mistake to avoid?

Connect each PC using one USB cable and two HDMI cables per system (HDMI IN A + HDMI IN B + USB IN per port); the common mistake is forgetting that HDMI cables are not included.

What ongoing maintenance does the switch require?

No scheduled maintenance is needed; the 5 V DC adapter powers the unit, and the rocker button handles PC selection mechanically.
