Triple-monitor KVM for two computers

This HDMI KVM switch lets two PCs share three monitors, a single keyboard and mouse, a headset and two USB 3.0 peripherals. It supports 4K resolution at 60 Hz and includes all required cables plus a wired remote button. The unit is driver-free across Windows, Linux and macOS.

Passive cooling with external power

The switch operates without fans and draws power from an included DC 5 V 2 A adapter, so it adds no audible noise to a workstation. LED indicators show the active port, and the metal enclosure dissipates heat during continuous use. No additional power supply is required beyond the bundled adapter.

Desktop footprint and cable bundle

Measuring 5.12 by 2.95 by 2.48 inches and weighing 3.26 pounds, the switch fits on a desk without needing rack space. Six HDMI cables and two USB 3.0 cables are supplied, reducing extra purchases. Each computer must provide three video outputs to drive all three monitors simultaneously.

Questions about this item

How do I connect both computers to the KVM switch using the included USB 3.0 and HDMI cables?

Plug the two supplied USB 3.0 cables and six HDMI cables between each computer and the switch, then connect the three monitors to the switch HDMI outputs, attach keyboard and mouse to the dedicated ports, and finally plug in the DC5V 2A power adapter before turning anything on.

What ongoing maintenance does the KVM switch require after installation?

No scheduled maintenance is needed; simply keep the ventilation slots clear of dust and verify cable connections remain firm if you move the unit.

What is the first limitation I will hit when running three 4K monitors at 60 Hz continuously?

The switch supports 3840 x 2160 at 60 Hz per display, so sustained use at that resolution and refresh rate is within its rated video capability.
