Driver support scheduled for release in 2010
Driver version 8.66 (Catalyst 9.10) or above is required to support ATI Eyefinity technology and to enable a third display you require one panel with a DisplayPort connector
ATI Eyefinity technology works with games that support non-standard aspect ratios which is required for panning across three 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
