Triple-Monitor KVM for Two Computers

This LUOM SW231-3HD switch lets two desktops or laptops share three HDMI displays, a single keyboard and mouse, and four USB 3.0 peripherals. It supports both extended and mirrored desktop modes across all three screens. Each connected computer must be able to drive three displays independently for extended mode to work. The unit is new and designed for multi-system workstations.

Rear-Facing Ports and Wired Remote

All HDMI and USB connectors sit on the back panel, keeping cables tidy and the desk surface clear. A 12 V 1 A power adapter is included to maintain stable operation when high-draw USB devices are attached. Switching between the two connected systems can be done via push buttons on the unit or the supplied wired desktop controller. LED indicators show the active port at a glance.

HDMI 2.1 Bandwidth and EDID Handling

The switch passes video up to 8K at 60 Hz and 4K at 120 Hz, compliant with HDMI 2.1 and HDCP 2.3 specifications. An integrated EDID emulator preserves display handshake data so resolution and layout persist after switching. Auto-scan cycles every 3 seconds if enabled. Buyers needing more than two computer inputs or more than three monitor outputs will require a different solution.
