STATUS_GRAPHICS_DDCCI_INVALID_MESSAGE_CHECKSUM
STATUS_GRAPHICS_DDCCI_INVALID_MESSAGE_CHECKSUM identifies a failed DDC/CI integrity check. Windows explicitly associates this result with corruption while data is transmitted from the monitor to the computer. The payload must not be treated as a valid feature value or capability response.
This is more specific than STATUS_GRAPHICS_DDCCI_INVALID_DATA: the API can name the failed checksum field. It is also distinct from receive failure, where a reply was not successfully obtained at all.
What makes a useful incident record
- Capture the physical monitor, connector path, operation, and the fact that a reply arrived but failed integrity validation.
- Compare repeated failures by output path; a persistent checksum mismatch is not evidence that the requested VCP feature is unsupported.
- Never bypass checksum validation by accepting the returned payload after this status.
