STATUS_GRAPHICS_DDCCI_INVALID_DATA

STATUS_GRAPHICS_DDCCI_INVALID_DATA reports a received DDC/CI value that is invalid for the operation. This is broader than a bad command field, length field, or checksum: those statuses identify a particular structural problem, whereas this one says the received data did not make sense to the monitor-configuration path.

Capture the operation and the raw reply at the boundary where it is available, then compare expected data type and value domain with the selected VCP feature or report request. Do not use a generic retry loop to silently accept a value that the API rejected.

Useful distinctions

Use STATUS_GRAPHICS_DDCCI_VCP_NOT_SUPPORTED when the feature is not implemented.
Use the message-length and checksum statuses when the protocol fields themselves identify the defect.
Check that the reply came from the intended physical monitor after dock, cable, or display-topology changes.
