Triple-Monitor KVM for Three Computers

This KVM switch lets three desktops or laptops share one keyboard, one mouse and three monitors at once. It supports both extended and mirrored display modes so each system can drive a multi-screen workspace. Four USB 3.0 ports are also shared across the three connected computers for peripherals and storage.

Check Your Computer Video Outputs First

Each computer must provide three video outputs — one HDMI and two DisplayPort — to use all three monitor ports. Verify that the host machine can drive three displays simultaneously by connecting three monitors directly before adding the switch. The switch requires a 12 V power adapter and USB 3.0 cables for every computer connection.

Passive Switching With External Power

The unit draws power from the included 12 V adapter and has no internal fans, so it adds no audible noise to the desk. Video switching is handled by front-panel push buttons or the wired remote without software drivers on Windows, Mac, Linux or Unix. USB 3.0 ports deliver up to 5 Gb/s data throughput while the switch routes 8K 60 Hz or 4K 144 Hz signals.

Questions about this item

Which cables and accessories come in the box with the SMA KVM switch?

The package includes the KVM switch, three USB cables, a wired remote controller, a user manual and a 12 V power adapter.

How do I decide whether my setup can use the 8K 60 Hz or 4K 144 Hz capability?

Both resolutions are supported on the DisplayPort 1.4 and HDMI 2.1 ports; choose 8K at 60 Hz for maximum pixel count or 4K at 144 Hz for higher refresh rate, provided your graphics cards and monitors support the chosen mode.

What does the 8K 60 Hz rating mean when the switch is connected to three computers and three monitors?

Each computer must provide three video outputs (one HDMI 2.1 and two DisplayPort 1.4) to drive all three monitors at up to 7680 × 4320 at 60 Hz simultaneously.
