AMD’s ATI Mobility Radeon™ series of GPUs are capable of processing HDCP signals ("HDCP ready”). Some third parties manufacture motherboards or graphics cards containing ATI Mobility 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.

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