3 screens setup, duplicating only 2

[GritHat]

I've been able to setup and run the application but found out that it is limited to only main and second screen, on a 3-screens setup it will only duplicate the main on the second one. I found this stackoverflow thread where the OP is having similar issues and had to change SetDisplayConfig parameters to actually factor in the extra monitor.

Edit: after unistalling all gpu drivers and removing all related registry keys and proceeding with a clean install with just the main monitor plugged everything worked as expected without any code change once the 2nd and 3rd monitors got plugged back in.
