[QUOTE="pigoo3, post: 1851716, member: 56379"] After connecting an external monitor and assuming: * The proper video port adapter is being used. * Both the video port adapter & video cable to the external monitor are good. * And the external monitor is fully functional. ...then at least the MacBook Pro's deskop should appear on the external monitor. If you're getting nothing on the external monitor...then there could definitely be an issue with the graphics hardware in the MacBook Pro. Also...don't forget to have the MacBook Pro plugged in when using an external monitor. Sometimes Apple portable computers will not allow you to use an external monitor unless the computer is plugged in (not allowed to use an external monitor while on battery power).
