View the official Windows Driver Kit DDI referenceNo description available.
The D3DKMDT_MONITOR_ORIENTATION_AWARENESS enumeration is used to describe the ability of a video output device (on the display adapter) to detect changes in the orientation (rotation angle) of a connected external display device.
D3DKMDT_MOA_UNINITIALIZEDIndicates that a variable of type D3DKMDT_MONITOR_ORIENTATION_AWARENESS has not yet been assigned a meaningful value.
D3DKMDT_MOA_NONEIndicates that the video output device is unable to determine the orientation of a connected external display device.
D3DKMDT_MOA_POLLEDIndicates that the video output device can determine the orientation of a connected external display device, and the display miniport driver can be aware of changes in orientation by polling the video output device.
D3DKMDT_MOA_INTERRUPTIBLEIndicates that the video output device can generate an interrupt when the orientation of a connected external display device changes.
The ChildCapabilities member of a DXGK_CHILD_DESCRIPTOR structure is a DXGK_CHILD_CAPABILITIES structure. The Type.VideoOutput member of a CHILD_CAPABILITIES structure is a DXGK_VIDEO_OUTPUT_CAPABILITIES structure. The MonitorOrientationAwareness member of a VIDEO_OUTPUT_CAPABILITIES structure is a D3DKMDT_MONITOR_ORIENTATION_AWARENESS value.
