HDCP over DisplayPort is not validated in Windows 7 Media Center.

Consider the following scenario: You have a computer connected to an external monitor using a DisplayPort connection. When playing back encrypted (protected) content in Windows 7 Media Center, you may see the following error:

Display driver error – the video playback device does not support playback of protected content.

In order for some forms of protected content to play back in Media Center, there must be HDCP compliance across the video card, the connection type and the external display. At this time, Windows 7 Media Center does not recognize a DisplayPort as being HDCP compliant; it only recognizes DVI and HDMI as HDCP compliant. Some protected content scenarios may work with DisplayPort with Media Center, but these are not officially validated.

Use a DVI-D or HDMI connection to your external display when playing back protected content in Windows 7 Media Center. This ensures that content is displayed natively without the output resolution being downsized.

Windows 7 Media Center supports video playback over any of the following connection types:

• Composite
• Component
• VGA
• DVI
• HDMI
• DisplayPort

However, for playback of protected content over a digital connection to an external display, a DVI or HDMI connection is required.
