User guide

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.

Note: A list of compatible adapters/dongles for your graphics card can be found at:

4.2.1 Multiple Displays

Your AMD Radeon™ HD 7750/7770 graphics card provides display functionality for up

to six displays using any combination of the following:

•

Any number of DisplayPort connections.

You can connect more than one display to a DisplayPort connection using a daisy

chain configuration or a hub (multi-display support is made possible through

the DisplayPort v1.2 standard).

•

Two connections between the dual-link DVI and HDMI connections.

The following table shows some examples of multiple display configurations; (A)

indicates an active adapter is used and (P) indicates a passive adapter is used. Display

abbreviations are DP = DisplayPort, DVI = dual-link DVI-I.

Once displays are connected to the graphics card, you can change how your displays

are configured using the Control Center software application. For more information,
