IddCxMonitorUpdateModes function

Description

An indirect display driver calls IddCxMonitorUpdateModes to have the OS update the mode list for a monitor. A driver that reports HDR support must use IddCxMonitorUpdateModes2 instead.

Parameters

`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_UPDATEMODES structure that contains the input arguments for this function.

Return value

IddCxMonitorUpdateModes returns STATUS_SUCCESS upon success; otherwise it returns an appropriate NTSTATUS error code.

Remarks

A driver can call IddCxMonitorUpdateModes to update the mode list previously reported for a monitor.
