I have four monitors running from one video card under nVidia driver … here is the nVidia screen:

In the nVidia config I have arranged them left to right: DFP-0 | DFP-2 | CRT-0 | DFP-1 (as above), because that is how they exist physically.
So I would like to be able to number the screens as 1-4 left to right as arranged above.
However i can find now way to configure this … the system defaults to numbering the Screens to 1, 4, 2, 3 … in that order left to right.
Here is the default state after booting the system … for MOST of the time

Mappings from the nVidia screen under GPU 0 - (GeForce GTX 650Ti) are:
CRT-0 => VGA-0 allocated Screen#2 by LEAP
DFP-0 => DVI-D-0 allocated Screen#1 by LEAP
DFP-1 => HDMI-0 allocated Screen#3 by LEAP
DFP-2 => DVI-D-1 allocated Screen#4 by LEAP
Firstly, is there anyway to choose/configure which monitor is referenced by which Screen Number??
Secondly, why does the system change allocation of Screen Number to Monitors at random it seems when rebooting? viz:

As you can see … this time on booting the system LEAP has allocated Screen numbers in a different order than as indicated initially???
This plays havoc with my workflow setup each time i restart the system.
I hope i have been able to describe the situation clearly, as it is rather convoluting…
Thanks in advance for any advice.
