I have 3 monitors, 2 in portrait mode and 1 in landscape.

When I login to my computer or logout, I would like my lock screen to be on DIsplayPort-0 and have my DVI-0/1 monitors either turned off or black and activated upon login.

The problem is when I turn my box on and get to the login screen, my two portrait monitors are in the wrong orientation until I login. When I set a lock screen wallpaper, the resolution is wrong on my two portrait monitors, opposed to my landscape monitor.

Thank ou for any help I can get.
