IDDCX_PATH2 structure (iddcx.h)
The IDDCX_PATH2 structure describes the mode to be set on a given monitor.
Syntax
struct IDDCX_PATH2 {
UINT Size;
IDDCX_MONITOR MonitorObject;
IDDCX_PATH_FLAGS Flags;
DISPLAYCONFIG_VIDEO_SIGNAL_INFO TargetVideoSignalInfo;
IDDCX_WIRE_FORMAT_INFO WireFormatInfo;
};
Members
Size
Total size of this structure, in bytes.
MonitorObject
An IDDCX_MONITOR object with the handle the driver provides to identify the monitor that this path is targeted at.
Flags
A IDDCX_PATH_FLAGS value with flags for this path, such as the path's active state and whether it has changed.
TargetVideoSignalInfo
A DISPLAYCONFIG_VIDEO_SIGNAL_INFO structure with details of the target mode signal. See Remarks.
WireFormatInfo
An IDDCX_WIRE_FORMAT_INFO structure with details of the signal to send to the monitor.
Remarks
The OS provides an IDDCX_PATH2 to the driver for every connected monitor, even if that monitor is not active.
DISPLAYCONFIG_VIDEO_SIGNAL_INFO's vSyncFreq value is the Vsync rate between the Indirect Display device and the connected monitor. vSyncFreqDivider is used to calculate the rate at which the OS will update the desktop image. The desktop update rate will be calculated by the formula: vSyncFreq / vSyncFreqDivider. vSyncFreqDivider cannot be zero.
