Triple-monitor KVM for three PCs

This KVM switch lets three computers share three monitors and four USB 3.0 peripherals. It supports extended mode, where each computer drives three different images, and copy mode, where one computer mirrors its image across all three displays. Switching is handled by front-panel buttons or the included wired remote.

Suits users with triple-head workstations

The unit requires every connected computer to provide two DisplayPort outputs and one HDMI output, so laptops or desktops with fewer video ports cannot use it. It also does not accept DVI-to-HDMI or VGA-to-HDMI adapters on the inputs, ruling out legacy graphics hardware.

Handles 8K at 30 Hz and 4K at 144 Hz

DisplayPort inputs reach 8K at 30 Hz and 4K at 120 Hz, while the HDMI input reaches 4K at 144 Hz and 8K at 60 Hz. The switch tops out at those refresh rates; higher frame rates or resolutions beyond 8K are not supported. Four USB 3.0 ports provide peripheral bandwidth for keyboards, mice and storage devices.

Questions about this item

What video outputs must each of my three computers provide to connect to this KVM switch?

Every computer needs two DisplayPort outputs and one HDMI output; the switch will not work with DVI-to-HDMI or VGA-to-HDMI adapters.

Can I keep using my existing 1080p monitors with this switch?

Yes, the switch is backward compatible with 1080p resolution alongside its higher 4K and 8K modes.

How do I verify the switch is routing video and USB correctly after I cable everything?

Press the wired remote or front button to change the active PC; each monitor should show that PC's desktop and the four USB 3.0 ports should enumerate on the selected computer.
