How to Use an ATI Unified AVStream Driver


ATI's unified AVstream drivers control ATI graphics cards and integrated graphics processors. They provide both AMD's display driver software for controlling the graphics processor's function and the Catalyst Control Center software for user configuration. The drivers are slightly different depending on the model of processors, but the Catalyst Control Center remains the same for each device. You can download the drivers from the Internet, but where you get them depends on the system's original configuration and the hardware manufacturer.

  • Download the unified drivers from AMD's website to support separately purchased graphics cards or cards in custom built computers. Search for your specific model of graphics processor, and download the software corresponding to your operating system.

  • Download the drivers from the manufacturer's website to support integrated graphics processors included with a pre-built PC. System builders often use slightly customized versions of the graphics drivers, and ATI may not have the exact version available on their website. Only use the drivers on ATI's website if the system manufacturer does not make the drivers available or fails to update the drivers.

  • Manage the unified AVstream drivers from the Windows Device Manager. Type "Device Manager" into the Start menu search bar and press "Enter" to open the tool. In older versions of Windows, find the Device Manager in the "Administrative Tools" Control Panel icon. Expand the "Display Adapters" section and double click on the ATI driver to open its settings. Use the Driver tab to uninstall the driver, roll it back to a previous version or temporarily disable it.

  • Check for online updates regularly. If a graphically intensive game or program does not display properly, ATI or the system manufacturer may have released an update that addresses the issue.

  • Double-click on the ATI symbol in the taskbar to open the Catalyst Control Center. This software allows you to set the graphics processor's usage parameters, and also set basic interface visual settings such as screen resolution and color.
