Hi,
for a kiosk project I’m trying to identify displays and set the screen arrangement to my needs.
This works well in cocoa/CoreGraphics with VendorID, ProductID and Serial number.
This works also well if I travers IORegistry for IODisplays.
But unfortunately sometimes I have similar displays without a serial number. Thus I cannot distinguish one display from another since their vendor and product ids are the same.
How do I resolve which IODisplay is on what port of the machine and how do I resolve the IODisplay from/to NSScreen ?
thx,
