STATUS_GRAPHICS_NO_RECOMMENDED_FUNCTIONAL_VIDPN
The miniport cannot propose a functional VidPN for this configuration
During VidPN negotiation, the operating system can ask the display miniport driver to recommend a functional VidPN topology and compatible modes. This status means the driver has no recommendation for the adapter state and constraints supplied by the caller.
That is not necessarily a generic driver crash. It can be a legitimate result when the connected targets, source count, bandwidth, private format constraints, or clone/extend policy leave no supported arrangement. It can also expose a driver that failed to enumerate cofunctional source and target modes before recommendation.
What to check
- Collect the requested topology, connected targets, and any pinned modes before asking for the recommendation.
- Check whether cofunctional mode enumeration returned candidates for the same source-target pairs.
- Distinguish no recommendation from a rejected committed VidPN; they happen at different phases.
