I manage to get the number of screens and the "virtual screen" which is the rectangle which all displays are placed within. I now only need to know where the each display's viewing rectangle within this virtual screen.

Code: Select all

  LibFunc>user32,GetSystemMetrics,VIRTUAL_SCREEN_x,76
  LibFunc>user32,GetSystemMetrics,VIRTUAL_SCREEN_y,77
  LibFunc>user32,GetSystemMetrics,VIRTUAL_SCREEN_w,78
  LibFunc>user32,GetSystemMetrics,VIRTUAL_SCREEN_h,79
  LibFunc>user32,GetSystemMetrics,MONITOR_count,80
  MDL>%MONITOR_count%%CRLF%%VIRTUAL_SCREEN_x%%CRLF%%VIRTUAL_SCREEN_y%%CRLF%%VIRTUAL_SCREEN_w%%CRLF%%VIRTUAL_SCREEN_h%

This one seems to have it but I have yet to found out how.

But today we only know the max and min (purple arrows) related to the 0,0 point (green arrow) which is the top left corner of the primary display. In order to know the visible areas + which display a visible area is attached to I would need to know these points shown in the image below (red arrows):



I have yet to stumble over an API call to retrieve this. If anyone knows please step into the light.
