Triple-monitor KVM for two computers

This USB-C HDMI KVM switch lets one keyboard, one mouse and three USB 3.0 peripherals control a laptop and a desktop across three HDMI monitors. It is built for users who need simultaneous multi-screen workflows without constantly swapping cables.

Passive cooling with external 12 V supply

The unit draws power from an included DC 12 V adapter and runs without fans, so it adds no audible noise to the desk. Typical power consumption stays low because the switch only routes video and USB signals rather than generating them.

Compact metal enclosure with wired remote

At 10 x 5 x 5 centimetres and 280 g the chassis fits behind monitors or under a laptop stand, and its ports are arranged for straight cable runs that reduce tangles. A push-button panel and the supplied wired remote give instant PC switching without reaching around the back.

Questions about this item

How do I connect a laptop via USB-C and a desktop via HDMI to the three monitor ports, and which step do people often miss?

Connect the laptop to the USB-C port and the desktop to the HDMI inputs, then attach all three monitors to the HDMI outputs. The step often missed is plugging in the DC 12V power adapter before switching PCs.

What maintenance or replacement will the DC 12V power adapter need over time?

The external DC 12V power adapter is the only part that may need replacement if it fails or the cable frays; the switch itself has no user-serviceable components.

At what resolution and refresh rate does the switch hit its bandwidth limit first during sustained use?

The bandwidth limit appears at 4K 60Hz across all three monitors; dropping to 4K 30Hz reduces the load and keeps the signal stable.
