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
