Thanks Ilia; 

I already checked the wiki page, with no success so far.

xrandr --setprovideroutputsource 1 0 seems to do nothing, either with a monitor connected to HDMI-1 or not. The second monitor is detected and available in the screen configuration tool of KDE, but it remains black, no window, nothing.

With a monitor conected in HDMI-1, here are the results of the commands : 
sigmar at TALABHEIM:~> grep . /sys/class/drm/card*-*/status 
/sys/class/drm/card0-eDP-1/status:*connected* 
/sys/class/drm/card1-DP-1/status:*disconnected* 
/sys/class/drm/card1-HDMI-A-1/status:*connected*
