I'm interested in changing the numerical identification of my monitors. It's the identification you see when you right click on desktop and choose screen resolution. To my knowledge, the numbers correspond to the hardware ports on the video card; there seems to be a hard-coded hierarchy of how the numbers play out. In my situation, the displayport *ALWAYS* gets assigned as display 1. So if I switch around my cables, I still can't avoid having the displayport cable getting that designation. I'd prefer to have the displayport identified as display 2, so I can make one of the DVI ports shown as display 1. This becomes an issue because when you use the Win+P shortcut, it can confuse which option corresponds to "PC Screen Only."
