STATUS_GRAPHICS_INVALID_MONITOR_FREQUENCYRANGESET
Frequency constraints are represented as a set
A monitor can expose supported timing constraints through frequency ranges. This status concerns the frequency-range-set object or its use in the current monitor-mode context. It is not the same as one bad frequency value; the container can be stale, associated with the wrong monitor source mode set, or otherwise invalid.
Monitor capability information can change after hot-plug or an EDID update. Use the current object obtained through the relevant VidPN interface, rather than retaining a range-set handle from an earlier target state.
Validate provenance
- Log the monitor source mode set, range-set handle, target identity, and current topology generation.
- Separate an invalid set from an invalid individual range and from a range that is simply not present in a valid set.
- Retain raw monitor capability data for comparison, but do not infer a range solely from a rounded refresh-rate label.
