Before you choose

Check the whole setup.

  • Connect each computer with both HDMI for video and USB-A to USB-C for peripheral data. Check the power connection and included cables before setup.
  • Match the GPU, monitor input and every cable to the intended resolution, refresh rate and HDR mode. “8K at 60Hz” is an advertised limit, not a guaranteed mode for your setup.
  • This listing states no EDID emulation and no hotkey switching; use the unit buttons or wired controller. Test display rearrangement, wake-from-sleep and USB reconnection in your own setup.
  • The listing says docking stations are not supported. Check adapters and source ports carefully; Raspberry Pi 5 needs a suitable micro-HDMI path. Safely eject shared storage before switching hosts.

Plan the role

Fit it to the system.

Place the KVM between compatible computers and one HDMI monitor. Each host needs a separate USB data connection as well as HDMI. The map shows two of the four possible host inputs; it is an example wiring plan, with no claim that these combinations have been tested together.
