I'm trying to figure out how to run 2 monitors with XP on parallels 6. I am using a Macbook Pro, with my 2nd monitor hooked up via the DVI port on the MacBook. I am going into XP display settings on Parallels, and the 2nd display is grayed out. I try selecting it and telling it to "extend desktop to display" or however it's worded, and my screen just briefly flashes, and then nothing happens. I want basically just my XP to cover both displays fullscreen so I can run another program on the 2nd monitor. I can't seem to get the 2nd monitor to activate or expand or do anything, all I see is just my mac os x desktop on the 2nd display. I can drag my parallels window over there, but I can't get my Parallels desktop to full screen and cover both. What am I doing wrong?
