Multi monitor script

PowerShell Help
1

Hi, I have copied / pasted / fudged together the script below and now need some advice on the next bit. Basically the script will be launched by a scheduled task created by SCCM to install a firmware upgrade of the users machine. When they click install it calls another ps script that actually does the upgrade. The issue I have is that we have a lot of users with multiple screens and their main screen will not always be the top most left in a pod or their left screen in on the desk. I have thought of generating a blank form that is a mile high by a mile wide to cover all of their screens but it will miss the top left or left screen if this is not the main screen. Also I dont know where to insert the blank form generation in the code below as it is my first play with XAML forms. Any help would be great
please note I have taken out the below to make it easier to debug :slight_smile:

I responded to your other post. Looks like it is in the review queue for the moderator, but you should be able to see it soon.

Just popped it in. Spam queue is acting weird lately.
