Dual-Monitor KVM for Four Systems

This HDMI KVM switch connects four computers to two monitors and four USB 3.0 peripherals. It supports mirror and extended display modes so each system can drive both screens independently. EDID simulation keeps window layouts intact when switching between the four hosts. The unit requires the included 12 V power adapter for stable operation.

Replaces Basic Single-Head Switches

A standard single-monitor KVM cannot drive two displays from four computers without extra hardware. This model consolidates both video paths and USB sharing in one box, removing the need for separate switchers or cable swapping. The jump is worthwhile when a workflow spans dual screens across multiple PCs, laptops or consoles. Single-monitor users or setups with only two hosts will not use the extra capacity.

HDMI 4K60 and USB 3.0 Bandwidth Limits

The HDMI interface caps video at 4K@60 Hz, with backward compatibility down to 1080p@120 Hz and 1440p@120 Hz. USB 3.0 peripherals share a 5 Gbps aggregate pipe, so simultaneous high-throughput devices may contend for bandwidth. RS232 control is fixed at 115200 baud and the wired remote reaches 1.5 m. HDMI cables are not supplied and must be sourced separately.

Questions about this item

What physical space does the KC402A unit itself occupy on a desk?

The switch measures 8.27 inches wide, 2.99 inches deep and 1.26 inches high, so it fits in a small footprint beside a keyboard.

Which step do users most often miss when setting up the four computers and two monitors?

Connecting the included 12 V power adapter before linking any HDMI or USB cables; the unit will not switch video without external power.

What ongoing upkeep does the wired remote or the USB 3.0 cables require?

No scheduled maintenance is needed; simply replace the 1.5 m remote or any USB 3.0 cable if the connectors become loose or damaged.
