Check Ultramon (you can use it as is or get their multi-monitor SDK): 
http://www.realtimesoft.com/ultramon/
Also look at www.ishadow.com, there is explicit support for multiple monitors 
and it works very well.If you need custom code to address your situation we can 
help you with that too.
 
For a quick solution I would try Ultramon.

If you turn off multiview within the nvidia driver this may fix your problem.  
Windows then treats it as two seperate monitors rather than one.  We have found 
that this works a lot better for poeple with more than two monitors. (with XPe 
FR3)

EnumDisplayMonitors API will give you details.
 
I've used code from http://vbnet.mvps.org/index.html?code/screen/index.html to 
manipulate monitor properties.

We have an application that automatically detects the number of monitors and 
the screen sizes when it launches, and then it will automatically fill the 
screen on the pc appropriately based on what it detects in Windows.  You can 
NOT manually size the window of this application. 
 
However the problem is that we have blade pcs, with special video cards for 
multiple monitors that we want to run this application on.  On these blade pcs, 
windows only thinks there is 1 monitor, because it is the nvidia driver that is 
handling the multiple monitor display rather than windows on these particular 
pcs.  This results in the application stretching across both monitors as if 
they were one large monitor which is not what should happen if the application 
properly detects 2 monitors. 
We are working with the application vendor to determine what exactly they are 
reading from in windows (API, reg key, ini file, etc) to detect the number of 
monitors but have not heard back.  We are also working with the hardware 
manufacturer to try and come up with a solution but also have had no luck 
there.  
 
My question is this:  does anybody know more specifically where in windows an 
application might read the number of monitors or the size of the screen? (API, 
reg key, ini file, etc)  All we have been told is "We check windows" and that 
is not really helping at this point.  I also know where to check in windows by 
opening up the display properties, but I am more interested in how applications 
might read and return this information rather than how a user interacts with 
it.  If I know this answer we might be able to come up with a solution to our 
issue. 
 
Thank You,
