If your graphics card includes a DisplayPort or Mini DisplayPort connection, you can
the following types of DisplayPort-compliant adapters/dongles with your graphics
card:
•
Adapters—Uses DisplayPort signals to transmit audio and video information
between variants of the same connection type (for example, Mini DisplayPort to
standard DisplayPort).
•
Active dongles—Allows connection from a DisplayPort connection to a non-
DisplayPort display using DisplayPort signals.
•
Passive dongles—Allows connection from a DisplayPort connection to a non-
DisplayPort display using non-DisplayPort signals.
The type of adapter/dongle used determines the number of displays that can be
supported by your graphics card. In general, more displays can be supported with
DisplayPort adapters and active dongles than with passive ones.
