IDDCX_DISPLAYCONFIGPATH2 structure (iddcx.h)
A IDDCX_DISPLAYCONFIGPATH2 structure contains path display configuration information.
Syntax
struct IDDCX_DISPLAYCONFIGPATH2 {
UINT Size;
IDDCX_DISPLAYCONFIGPATH2_FLAGS Flags;
IDDCX_MONITOR MonitorObject;
IDDCX_DISPLAYCONFIG_MODE Mode;
UINT MonitorScaleFactor;
DISPLAYCONFIG_2DREGION MonitorPhysicalSize;
IDDCX_DISPLAYCONFIG_MONITOR_COLORIMETRY MonitorColorimetry;
UINT MonitorSdrWhiteLevel;
};
Members
Size
Size, in bytes, of this structure.
Flags
A bitwise OR of IDDCX_DISPLAYCONFIGPATH2_FLAGS values that identify the flags for this path, including which fields contain valid data.
MonitorObject
An IDDCX_MONITOR object handle that the driver provides to identify the monitor this path is targeted at.
Mode
If valid, this field is a IDDCX_DISPLAYCONFIG_MODE structure that contains details of the mode to be set for the monitor in this path.
MonitorScaleFactor
If valid, this field specifies the requested monitor DPI for this path. This value is just a hint and OS may override it to ensure the DPI configuration of the session is valid. Valid values are 100 to 500 inclusive.
MonitorPhysicalSize
If valid, this field is a DISPLAYCONFIG_2DREGION structure that contains the physical width and height override for the specified monitor, in millimeters. A value of zero means no override.
MonitorColorimetry
If valid, this field is a IDDCX_DISPLAYCONFIG_MONITOR_COLORIMETRY structure that contains the colorimetry details for the specified monitor.
MonitorSdrWhiteLevel
If valid, this field specifies the new white level, in nits, to be used for SDR content on this monitor when in an HDR mode.
Remarks
An indirect display driver (IDD) calls IddCxAdapterDisplayConfigUpdate2 when it receives a new display configuration. It passes an array of IDDCX_DISPLAYCONFIGPATH2 structures in IDARG_IN_ADAPTERDISPLAYCONFIGUPDATE2.
For more information about HDR support, see IddCx version 1.10 updates.
