Using Your MacBook Pro

When an external monitor or TV is connected, you can either have the same image

appear on both the built-in display and the external monitor (known as video mirroring)

or use the external monitor to extend the size of the Mac OS desktop (known as

dual-display or extended desktop mode). By default, your MacBook Pro starts up in

dual-display mode. Press the F7 (i) key to switch between dual-display and video-

mirroring modes.

If you want sound to come from the external display, such as a projector or TV, you

need to connect an audio cable (not included) from the computer’s headphone (f )

port to that device.

Note: Because of the display limitations of most TVs, images displayed on the TV

screen will be of lower quality than those on the built-in display or an external monitor.
