Multiple Monitors:  Always know that "1" is 1, "2" is 2 etc...

Hey guys.  I'm trying to write an app (in VB.net on Win7Pro x64) that displays 8 different images on 8 different screens depending on info coming into a PC.  These screens are several hundred feet appart, so I am required to use an extender box, such as the StarTech HDMI over IP Extender (IPUSB2HD2).  Their software basically presents each box to Windows as a new display adapter.  

I have this working just fine, but the problem is if/when one or more of those adapters/screens powers off.  The software disconnects it from the device (obviously) and then in turn Windows loses track of which number screen that was.  In other words, for example screen 3 is no longer screen 3.

My question is this:  is there a way for me to identify something about screen X that always tells me screen X is screen X?  Sort of like a MAC address for NICs?  That way, I can always direct my output to that identifier, rather than just "screen X" and trusting windows to handle it correctly?

I hope that makes sense and thanks for your time.

Monitors are always a pain. You could possible use the "Physical device object name" to keep track of which monitor is which. Not sure how easy/hard that is to pick that value up in VB though (WMI maybe?)
