I have a configuration where 5 monitors are connected to the same server. Following the hints in:  
[https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/89/0/launch-project-to-multiple-monitors](https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/89/0/launch-project-to-multiple-monitors)  
I managed to launch 5 times the same project on the server with 5 different startup pages, one different page for each monitor.  
I select the startup page for each monitor in the client event script: there I get the value of the Monitor client variable which is set by the Native Client Launcher

`thisMonitor=system.tag.read("[Client]Monitor").value
system.gui.setScreenIndex(thisMonitor)
`  
then, based on the thisMonitor value, I show a different startup page in each monitor:

`if thisMonitor==0:
	system.nav.swapTo("MainPage")
elif thisMonitor==1:
	system.nav.swapTo("RecipeMain")
elif thisMonitor==2:
	system.nav.swapTo("MotorsPage")
`  
What’s weird, is that the monitor index is not the same as the Windows Identify command shows. Second if I unplug a monitor and then plug it in again, monitor numbering changes and my script is no more valid.  
I know this is not a problem of Ignition, but maybe someone of you has already found a solution.

Thank you in advance,  
regards

This sounds like an ambitious setup.  
I would like to see it.

Can you run the script on a timer do detect changes?  
Can you hook into Java classes and get notification of monitor count change?
