I'm trying to run dual screens in bootcamped XP. My Dell 2005FPW dualscreens with my MBP (latest revision) well in OSX, but will not ds in XP. I go into the windows options and the "Make primary monitor" button for Screen 2 (the dell) is greyed out. I did a little research and found that some videocards (especially laptop ones) won't do ds. But I don't understand why it does it in OSX but not XP. Do I need to set some setting in the BIOS or something? I'll even settle with making the Dell monitor my primary monitor (with the MBP screen blank or mirroring). I really just want it on my external monitor so I can run games on it. Thanks!
