D3DKMDT_MONITOR_ORIENTATION_AWARENESS Enumeration

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.

Syntax

typedef enum _D3DKMDT_MONITOR_ORIENTATION_AWARENESS {
  D3DKMDT_MOA_UNINITIALIZED,
  D3DKMDT_MOA_NONE,
  D3DKMDT_MOA_POLLED,
  D3DKMDT_MOA_INTERRUPTIBLE
} D3DKMDT_MONITOR_ORIENTATION_AWARENESS;

Constants

D3DKMDT_MOA_UNINITIALIZED Indicates that a variable of type D3DKMDT_MONITOR_ORIENTATION_AWARENESS has not yet been assigned a meaningful value.
D3DKMDT_MOA_NONE Indicates that the video output device is unable to determine the orientation of a connected external display device.
D3DKMDT_MOA_POLLED Indicates 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_INTERRUPTIBLE Indicates that the video output device can generate an interrupt when the orientation of a connected external display device changes.

Remarks

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.

Requirements
