"to operate two computers with Displayport output on one Displayport monitor and / or one HDMI monitor." "In addition, there is a Displayport and an HDMI output, making it possible to connect two monitors, only one of which can be active." First "and / or" means there is the possibility of connecting 2 monitors, then "of which only one can be active"... What applies now? Is it possible to connect two screens (both for the same source)?
