OpenCL compliant driver and SDK release scheduled for later 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 can support up to 3 displays using a single enabled ATI Radeon™ graphics card – the number of displays may vary by board design and you should confirm exact specifications with the applicable manufacturer before purchase. ATI Eyefinity technology works with games that support non-standard aspect ratios, which is required for panning across multiple displays. To enable more than two displays, additional panels with native DisplayPort™ connectors, and/or certified DisplayPort™ adapters to convert your monitor’s native input to your cards DisplayPort™ or Mini-DisplayPort™ connector(s), are required. Digital management rights restrictions may apply.
Requires application support for ATI Stream technology
Digital rights management restrictions may apply
ATI CrossFireX™ technology requires an ATI CrossFireX Ready motherboard, 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
Not available with Blu-ray picture-in-picture
May not be available for all desktop resolutions with Windows Aero enabled
Adobe Flash video acceleration and post-processing is supported for H.264-encoded content. Requires Adobe Flash Player 10.1 plug-in and Catalyst 9.11 or higher.
Blu-ray or HD DVD drive and HD monitor required
Requires Blu-ray movie disc supporting dual streams or picture-in-picture
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
