DXGK_SYNC_LOCK_STYLE enumeration (d3dkmddi.h)

Used in the call to DxgkDdiSetTimingsFromVidPn to describe the style of display synchronization to be applied.

Syntax

typedef enum _DXGK_SYNC_LOCK_STYLE {
  DXGK_SYNC_LOCK_STYLE_NONE,
  DXGK_SYNC_LOCK_STYLE_IDENTICAL
} DXGK_SYNC_LOCK_STYLE;

Constants

 
DXGK_SYNC_LOCK_STYLE_NONE
Indicates that this path is not synchronized. If the Input.SyncLockStyle value of DXGK_SET_TIMING_PATH_INFO is set to this value, then the Input.SyncLockGroup should be set to zero.
DXGK_SYNC_LOCK_STYLE_IDENTICAL
Indicates that this path is synchronized with other paths with the Input.SyncLockGroup set to the same non-zero value where all the paths have an identical target mode.

Remarks

The sync styled defined for WDDM 2.4 - WDDM 2.6 do not allow the styles applied within a group to be mixed, since a path with DXGK_SYNC_LOCK_STYLE_IDENTICAL can only be synchronized with another path with DXGK_SYNC_LOCK_STYLE_IDENTICAL. However, in future releases, sync styles will support and potentially require different styles within a group.
