IDDCX_MONITOR_DESCRIPTION structure (iddcx.h)

  • Article

A IDDCX_MONITOR_DESCRIPTION structure provides a monitor description.

Syntax

struct IDDCX_MONITOR_DESCRIPTION {
  UINT                           Size;
  IDDCX_MONITOR_DESCRIPTION_TYPE Type;
  UINT                           DataSize;
  PVOID                          pData;
};

Members

Size

Total size of the structure, in bytes.

Type

A IDDCX_MONITOR_DESCRIPTION_TYPE value that describes the monitor's type.

DataSize

The size in bytes of the monitor description data that pData points to.

pData

Pointer to the monitor description data. The data layout depends on Type as follows:

  • If Type is IDDCX_MONITOR_DESCRIPTION_TYPE_EDID:
    • If DataSize > 0 and pData != NULL, pData points to an EDID data formatted monitor description.
    • If DataSize = 0 and pData = NULL, no monitor description is available.
  • If Type is IDDCX_MONITOR_DESCRIPTION_TYPE_DISPLAYID_AND_EDID, the monitor description starts with a DisplayID description followed by EDID without any padding in between. The EDID format should contain all available data blocks and be present. The call to connect the monitor will fail if DisplayID is missing or invalid, or if EDID is missing.
