Triple-Monitor KVM for Two PCs

This HDMI 2.1 KVM switch lets two computers share one keyboard, one mouse and three monitors. It is built for users who need simultaneous multi-display access across a pair of workstations or a workstation and a gaming rig.

8K60 and 4K144 headroom

The switch passes video bandwidth up to 48 Gbps, supporting resolutions up to 8K at 60 Hz and 4K at 144 Hz. Triple-monitor duplication and extended modes require each computer to provide three HDMI outputs; bandwidth drops if any link in the chain does not meet the same specification.

Fanless 12 V desktop unit

The 15 × 6.5 × 4.8 cm enclosure draws power from an included 12 V adapter and has no moving parts, so it adds no audible noise. Front-panel LEDs show the active host, while push buttons and a wired remote give instant switching without software overhead.

Questions about this item

Will the SMA KVM switch work with my older graphics card that only has HDMI 2.0 outputs?

Yes, the switch supports HDMI 2.1 but is backward compatible, so your HDMI 2.0 card will run at its maximum supported resolution up to 4K@60Hz.

How can I verify the SMA KVM switch is passing a 4K@144Hz signal correctly after connecting everything?

Check that the front-panel LED indicators show the active input, then confirm 4K@144Hz appears in your OS display settings on all three monitors.

Which cables are included with the SMA KVM switch and what must I buy separately?

The box contains the switch, two USB 3.0 cables, a wired remote, a 12V power adapter and a manual; you need to supply six HDMI cables (three per computer).
