I just bought an AMD Radeon™ graphics card. How do I configure my PC to take advantage of AMD Radeon™ Dual Graphics?

To take advantage of AMD Radeon™ Dual Graphics, you must use a compatible AMD A-Series APU to pair with your supported AMD Radeon™ graphics card. After installation of your graphics card, visit the AMD Graphics Drivers and Software Page, to download and install the latest AMD graphics drivers. After driver installation, the option to enable AMD Radeon™ Dual Graphics should become available in the AMD Catalyst Control Center or the Radeon Settings page in Radeon Software Crimson Edition.

Once installed, go into the “Performance” section of the AMD Catalyst Control Center or go to the “Gaming, Global Options” tab in Radeon Settings and toggle the AMD Crossfire™ technology option to “On” or “Enable Crossfire™”. This will allow the AMD A-Series APU graphics to work in tandem with the select AMD Radeon™ GPU installed for increased graphics performance.

Where do I plug my monitor in to get the best performance when using AMD Radeon™ Dual Graphics technology?

For best performance, AMD recommends plugging the display into your fastest GPU. This will ensure that even applications that do not take advantage of AMD Radeon™ Dual Graphics will still be able to run on the faster graphics card in your system. We recommend that you plug your monitor into the AMD Radeon™ GPU with the higher model number. If that is your APU, plug into the motherboard, if it is your discrete graphics card, plug into that.

With a multi-monitor setup, why do some of the displays become disabled when I enable AMD Radeon™ Dual Graphics?

AMD Radeon™ Dual Graphics is a form of AMD CrossFireX technology, and, with the current solution, only displays from the “master” graphics device (the one that monitors are plugged into) are available. The other displays are disabled. To ensure your displays remain available, make sure to connect your displays to the “master” graphics device.

The "master" device settings can be found in the AMD Catalyst Control Centre under the "Information, Hardware" tab or in Radeon Settings under the "System, Hardware" tab.

Additional hardware (e.g. HD or 4K monitor, USB 3.0 ports, wirelessly enabled HDTV) and/or software (e.g. multimedia applications and/or Wi-Fi access) are required for the full enablement of some features. HD/4K video display requires an HD/4K video source. Not all features may be supported on all components or systems - check with your component or system manufacturer for specific model capabilities and supported technologies.
