Driver support scheduled for release in 2010.
Driver version 8.66 (Catalyst 9.10) or above is required to support ATI Eyefinity technology.. Actual number of attachable monitors will vary by notebook model.
ATI Eyefinity technology works with games that support non-standard aspect ratios which is required for panning across multiple displays.
Requires application support for ATI Stream technology.
Digital rights management restrictions may apply.
ATI CrossFireX™ technology requires an ATI CrossFireX Ready motherboard, an ATI CrossFireX™ Bridge Interconnect (for each additional graphics card) and may require a specialized power supply.
ATI PowerPlay™, ATI Avivo™ and ATI Stream are technology platforms that include a broad set of capabilities offered by certain ATI Radeon™ HD GPUs. Not all products have all features and full enablement of some capabilities and may require complementary products.
Upscaling subject to available monitor resolution.
Blu-ray or HD DVD drive and HD monitor required.
Requires Blu-ray movie disc supporting dual 1080p streams.
Playing HDCP content requires additional HDCP ready components, including but not limited to an HDCP ready monitor, Blu-ray or HD DVD disc drive, multimedia application and computer operating system.
Some custom resolutions require user configuration.
Requires 3D stereo drivers, glasses, and display.
OpenCL compliant driver and SDK release scheduled for later in 2010.

Performance, technologies and features listed above can vary with specific notebook implementations. Please consult with Notebook vendor for a complete list of supported features.

ATI Radeon™ HD graphics chips have numerous features integrated into the processor itself (e.g., HDCP, HDMI, etc.). Third parties manufacturing products based on, or incorporating ATI Radeon HD graphics chips, may choose to enable some or all of these features. If a particular feature is important to you, please inquire of the manufacturer if a particular product supports this feature. In addition, some features or technologies may require you to purchase additional components in order to make full use of them (e.g. a Blu-Ray or HD-DVD drive, HDCP-ready monitor, etc.).
