IDDCX_PATH structure (iddcx.h)
The IDDCX_PATH structure describes the mode to be set on a given monitor.
Syntax
struct IDDCX_PATH {
UINT Size;
IDDCX_MONITOR MonitorObject;
IDDCX_PATH_FLAGS Flags;
DISPLAYCONFIG_VIDEO_SIGNAL_INFO TargetVideoSignalInfo;
};
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.
Remarks
The operating system provides an IDDCX_PATH 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.
