View the official Windows Driver Kit DDI referenceNo description available.
An indirect display driver calls IddCxMonitorUpdateModes2 to have the OS update the mode list for a monitor.
MonitorObject[in] An IDDCX_MONITOR object that is the OS's context handle for the monitor. The OS provided this handle in a prior call to IddCxMonitorCreate.
pInArgs[in] Pointer to an IDARG_IN_UPDATEMODES2 structure that contains the input arguments for this function.
IddCxMonitorUpdateModes2 returns STATUS_SUCCESS upon success; otherwise it returns an appropriate NTSTATUS error code.
A driver can call IddCxMonitorUpdateModes2 to update the mode list previously reported for a monitor.
Drivers sending modes with SDR WCG or HDR parameters will fail if they have not also reported IDDCX_ADAPTER_FLAGS_CAN_PROCESS_FP16 in the IddCxAdapterInitAsync call. Also, drivers reporting IDDCX_ADAPTER_FLAGS_CAN_PROCESS_FP16 can only call IddCxMonitorUpdateModes2; calling IddCxMonitorUpdateModes is an error.
For more information about HDR support, see IddCx version 1.10 updates.
