DisplayCAL

I am sorry I am not technically proficient, so I don’t know all the ins and outs of this, but I just installed your software to use with a newly purchased Colormunki Display.  This is my first time using a colorimeter.  When I follow your instructions for Quick Start, the Display and Instrument fields are grayed out.  When I try to detect a display, absolutely nothing happens.  We have two different video cards in our computer, with each one assigned to a different monitor.  I am not the one who has set up our computer, so I don’t all the technical data around it, but any advice would be appreciated.  I am about ready to give up on bothering to color correct my display.
