Show HN: Multi-monitor KVM using just a USB switch

To clarify (the first thing I wondered) each computer needs its own HDMI cable plugged into its own input on the monitor. So not true KVM as many people would think of it, but this saves you from having to use the monitor's input selector.

At least one of the computers must be on and running Windows, but maybe only one?

ddcutil can do input switching on Linux, so it would be easy to do something similar there. I already do a similar thing with xrandr for monitor rotation, running a script when I press a hotkey.

Yes only one computer needs to have Windows and run the program.

If it detects the USB device being inserted, it changes monitor inputs to the Windows computer. If it detects the USB device being removed, it changes monitor inputs to the Linux computer.

Would you consider making a macOS port?

This doesn’t seem to work on all setups, see https://news.ycombinator.com/item?id=39333869.
