Tips & Warnings

• The MacBook does not have the video limitations found on an iBook. A MacBook and MacBook Pro can perform a screen extension and mirror its video to an external display.
• You can have a MacBook Pro running at a different resolution than an external display. You can set the Macbook Pro 15-inch resolution at 1440 by 900 and the external display to 1680 by 1050. You can drive the external screen to its fullest resolution as primary monitor, while using the MacBook Pro's screen for instant messaging, email or Internet surfing.
