CCD DDIs

The Connecting and Configuring Displays (CCD) feature introduced in Windows 7 provides for improved display miniport driver control of display devices.

The following reference topics describe the CCD device driver interfaces (DDIs) that are available to developers of display miniport drivers.

• System-Implemented Functions:

  • DXGK_MONITOR_INTERFACE_V2::pfnGetAdditionalMonitorModeSet
  • DXGK_MONITOR_INTERFACE_V2::pfnReleaseAdditionalMonitorModeSet

• Driver-Implemented Function:

  • DxgkDdiQueryVidPnHWCapability. A display miniport driver that supports CCD must implement this function.

• Relevant structures:

  • D3DKMDT_VIDPN_HW_CAPABILITY
  • D3DKMDT_VIDPN_PRESENT_PATH_SCALING_SUPPORT
  • D3DKMT_POLLDISPLAYCHILDREN
  • D3DKMT_RENDERFLAGS
  • DISPLAYID_DETAILED_TIMING_TYPE_I_ASPECT_RATIO
  • DXGKARG_QUERYVIDPNHWCAPABILITY
  • DXGK_MONITOR_INTERFACE_V2
  • DXGK_PRESENTATIONCAPS
  • DXGK_TARGETMODE_DETAIL_TIMING

• Relevant Enumerations:

  • D3DKMDT_VIDPN_PRESENT_PATH_SCALING
  • DISPLAYID_DETAILED_TIMING_TYPE_I_ASPECT_RATIO
  • DISPLAYID_DETAILED_TIMING_TYPE_I_SCANNING_MODE
  • DISPLAYID_DETAILED_TIMING_TYPE_I_STEREO_MODE
  • DISPLAYID_DETAILED_TIMING_TYPE_I_SYNC_POLARITY
