ATI Catalyst™ Software Suite

AMD’s ATI Radeon™ X and Radeon™ 9550 series of GPUs are capable of processing HDCP signals ("HDCP ready"), however not all ATI Radeon graphics cards are HDCP ready. Please check the applicable ATI Radeon graphics card specification to determine if a particular ATI Radeon graphics card is HDCP ready. Some third parties manufacture graphics cards containing ATI Radeon GPUs -- you can inquire of them which models, if any, are HDCP ready. In addition, playing HDCP content requires additional HDCP ready components, including but not limited to an HDCP ready monitor, disc drive, multimedia application and computer operating system.
With optional HDTV adapter available from ATI Online Store
