multiple screen information

Hello All,
I am trying to determine a way to get the x y co-ordinate ranges for an external screen plugged into the hdmi port of my computer. I've looked around and there is supposedly a .bounds property that can be used to set a form to an external monitor but I am troubleshooting something and I need to know the actual numbers for the co-ordinate ranges.
Thank you for any help.
Jeff

And in the codebank are a couple of submissions that might worth looking at
