How do I make my secondary monitor the primary monitor?

What graphics card do you have? If it is a NVIDIA one you can install the NVIDIA control panel and use that to configure multiple monitors. Otherwise go to control panel, display, change the appearance of your display, If not sure which monitor number is which click the identify on, make sure display is on multiple display, then in the multiple display option set it to either duplicate or select show the desktop only on the monitor you want as primary (I'm guessing that is monitor 2 but do the detect and identify if not sure)
