re-tested via ssh to to eliminate delayed events (and i now have 3 screens...)

xset dpms force off:
all displays turn off

then almost immediately DVI-0 and HDMI-0 turn back on but DisplayPort-1 stays
off
xset q states "monitor is off"

then i press shift( cause an event):
xset q states "monitor is on"
DVI-0 and HDMI-0 stay on and DisplayPort-1 stays off

then "xset dpms force off" again
all 3 displays turn off
xset q states "monitor is off"

then i press shift( cause an event):
all 3 displays turn on
xset q states "monitor is on"

this is a repeatable loop
