Triple Monitor KVM Switch for Three PCs

This SMA KVM switch lets you control three computers with a single keyboard, mouse and triple-monitor setup. It provides two DisplayPort and one HDMI video inputs per system, plus four USB 3.0 ports for shared peripherals. The unit is designed for users who need simultaneous access to three workstations without swapping cables.

Upgrade from Dual Monitor or Single PC KVMs

The switch replaces setups that only support two displays or a single computer, adding a third video path and three host ports. The jump is worth it when your workflow demands three independent 8K@60Hz or 4K@144Hz outputs across three machines. It also consolidates USB 3.0 hubs, removing the need for separate docking stations.

Verify Host Video Outputs and Cabling First

Each computer must supply one HDMI and two DisplayPort signals to fill the three monitor ports. Laptops with only USB-C video need active USB-C to DP and HDMI adapters or a compatible dock. The package includes 1.5 m USB 3.0 cables, a 1.52 m wired remote and a 12 V power adapter for high-draw USB devices.

Questions about this item

What cable lengths are included for the three DisplayPort and HDMI connections to the computers?

The package supplies three USB 3.0 cables at 1.5 m (4.9 ft) and a 1.52 m (5 ft) 12 V power adapter; video cables are not included.

Which switching method avoids the common mistake of leaving the front-panel buttons inaccessible?

Use the included 1.52 m wired remote controller so the switch can be placed out of the way while the remote stays on the desk.

When must the 12 V power adapter be connected instead of relying on bus power?

Connect the 12 V adapter when attaching high-power USB devices such as external HDDs, SSDs or digital video cameras.
