MacBook Pro: Display issue related to "hot-plugging"
When hot-plugging an external display into your MacBook Pro, you may notice the external display occasionally stays dark, or the internal display of the MacBook Pro appears to flash or turn black.
Sometimes, when switching from an S-Video to a DVI connection, the internal display may appear black or display only the mouse cursor.
