That would be great and is what I will try next.  First step will be to
switch the BIOS back to Optimus and then see if I can configure the Intel
Integrated GPU for the laptop screen and the Nvidia card for the VGA
output.  (Is this what you were suggesting?)  Would this prevent e.g.,
Mirror Displays from working?  Maybe I could get the integrated GPU to
handle the laptop and the VGA out, and the Discrete Nvidia to support the
DisplayPort.  This would be ideal, as at hope (with external monitor
attached via DisplayPort) I don't need to mirror displays.

Do you think this sounds possible?  (I wonder if I'll need to load
Bumblebee for this...)

Thanks!
