Mini Display Port Not Working Until Restart

[mynewromantica]

When I plug in my external monitor it does not turn on until I restart my computer with the cord plugged in. I know it is not an issue with the monitor because I can plug in my wife's computer without any issues. Also, when I unplug my monitor before restarting the computer, my MBP screen flashes blue as if it did actually recognize something was there.

Any ideas?

This sounds like an annoying issue.

Try hitting Command-F1 after you plug in the monitor. That switches between the display modes (extended vs mirrored), but might also force it to detect the monitor. There's also a button in System Preferences -> Displays that says Detect Displays, which might be of use.

Of course, it could also be faulty in some way. If this is a brand new machine, or even one within warranty, I'd slip into an Apple Store sometime and ask them to take a look.
