The Catalyst Control Center is where all the settings for the PowerColor HD 4890 are available. There's a lot that you can change and set, but I am only going to go over the main parts of it.
Information Center: The Information Center is where you can view everything about the hardware and software associated with the video card, such as driver versions and hardware specifications.
Display Properties: The Display Properties tab is where you can set the resolution, refresh rate override and the preferred monitor if more than one is available. In the Display options you can manually detect your display or you can choose to let the CCC do this for you.
Digital Panel: The Digital Panel is where you can set and view monitor information, HDTV settings, ATI's AVIVO color settings, and LCD Overdrive to apply LCD settings that override the monitor's settings.
3D & Color: In the 3D tab you can adjust general image quality settings as well as Anti-Aliasing, Anisotropic Filtering and color schemes. There are also a few settings for DirectX and OpenGL.
AVIVO Video & ATI Overdrive: AVIVO settings allow you to alter the color settings for better viewing. ATI Overdrive gives the user control of the GPU and memory frequencies. For novice users there is an automated clock configuration utility that will find the best overclock for your system settings.
