Triple-monitor KVM for two computers

This HDMI 2.1 KVM switch lets two computers share three displays and four USB 3.0 peripherals. It supports extended and duplicate modes so each machine can drive three unique screens or mirror the same image across all monitors. Each connected computer must provide three HDMI outputs to use the triple-monitor capability. Buyers whose laptops only offer one or two video outputs cannot use the full three-screen layout.

Passive cooling with external 12 V supply

The unit runs without internal fans, relying on its metal chassis for heat dissipation during normal operation. A 12 V DC adapter powers the switch and the four downstream USB 3.0 ports, delivering up to 5 Gbps per port for attached drives or accessories. No additional power supply sizing guidance is provided by the manufacturer. Builders who need redundant or rack-mounted power inputs should look elsewhere.

Wired remote and front-panel switching included

The package supplies a wired push-button remote, two USB 3.0 cables, the 12 V adapter and a user manual. The remote duplicates the front-panel switch function so the main box can be tucked out of sight while switching remains accessible. LED indicators show which computer is active. No configuration software or drivers are bundled; the device operates purely through hardware button presses.
