O.K. I am a complete and total mac newb so it is entirely likely that I am missing something really, really simple in OSX, but when I hook up y external monitor at work to the display port on my mini9 the screen goes completely black on both the dell and the monitor, in the past it would just show part of the desktop and never mimic what was going on the dell9's display.
What am i missing, btw the Dell9 is using DEllefi 1.1 and has a fully patched OSX 10.5.6 install.
The display that i am trying to utilize is a dell 17" roughly two or three years old.
Thanks for any assistance!
