Thanks Boudhayan,

I had come across Zaphod a few times but had not yet made sense of it.  
The example you point to may give me a starting point.  The only 
parameters I cannot figure out are the "Actual connector" values.  I 
have the possibilities:

DP-1
DP-2
HDMI-A-1
HDMI-A-2

I have a monitor plugged into the DisplayPort connection and one into 
the HDMI connection. I suppose I could guess that they are both #1.  I 
will try that and see if it lets the smoke out :-)
