This Mini Display Port to VGA adaptor converts the digital signal to an analog VGA signal.allowing you to connect a standard analog monitor, projector, or LCD that uses a VGA connector or cable to a Mac or other device with a Mini DisplayPort.
Limitations to its use are:-
The Mini DisplayPort specification includes HDCP copy protection, allowing DRM-enabled content providers, including the iTunes Store, to disable playback on any external displays that are not HDCP compliant.
The current MacBook and MacBook Pro range is unable to provide an audio signal through the Mini DisplayPort, and only does so over USB or the audio line out port instead.
All sizes are approximate.
Products may vary from illustration.
