    display-switch

    display-switch

    Turn a $30 USB switch into a full-featured multi-monitor KVM switch

It is supposed to be installed on all computers that could be connected to these monitors since the app only switches monitors "one way" and relies on itself running on the other computers to switch it "the other way" as needed.
