STATUS_GRAPHICS_DDCCI_INVALID_CAPABILITIES_STRING
STATUS_GRAPHICS_DDCCI_INVALID_CAPABILITIES_STRING means the monitor returned a capabilities string that Windows could not accept under the relevant DDC/CI, ACCESS.bus, or MCCS rules. It is not automatically evidence that every monitor feature is unusable; it is a warning that the advertised feature inventory cannot be trusted as a conforming capabilities record.
Windows describes the capabilities string as ASCII data carrying static monitor information, supported VCP codes, and values for noncontinuous features. A parser must not turn a malformed record into an authoritative allow-list.
What to preserve
- Store the exact returned string, its reported length, the physical-monitor identity, and the operation that retrieved it.
- Keep malformed capability data separate from a known unsupported VCP code; one is a metadata-format failure, the other is a feature result.
- Do not “repair” arbitrary capability strings in application logic unless a vendor-specific interoperability rule is explicitly maintained and audited.
