ERROR_GRAPHICS_INVALID_MONITOR_FREQUENCYRANGE_CONSTRAINT
Interpret the result in its owning layer: graphics invalid monitor frequencyrange constraint
The useful interpretation of ERROR_GRAPHICS_INVALID_MONITOR_FREQUENCYRANGE_CONSTRAINT (0xC0262358) starts at the vidpn boundary: a frequency-range constraint is malformed or inconsistent with the monitor capability set. In practical terms, inspect monitor timing constraint before changing application-wide graphics settings.
Normalize timing units and interval ordering
Frequency constraints combine horizontal rate, vertical rate and pixel-clock limits originating from monitor descriptors, overrides or driver data. Capture raw numerators, denominators and units before conversion; then verify minimum does not exceed maximum and that the origin is retained. Use one timing known from the monitor target mode set as a control. A malformed custom constraint must be removed without discarding the monitor's valid EDID-derived modes.
Capture before recreating objects
| Capture item | Why it matters |
|---|---|
| Current graph state | VidPN, topology, source and target mode sets, and the present path connecting them |
| Supporting trace | source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data |
| Object identity | monitor timing constraint |
| Rejected condition | a frequency-range constraint is malformed or inconsistent with the monitor capability set |
| What to capture | horizontal/vertical ranges, pixel-clock limits, constraint type, target mode and descriptor origin |
Reproduce one variable at a time
- Capture the failing state. Record horizontal/vertical ranges, pixel-clock limits, constraint type, target mode and descriptor origin.
- Remove the custom constraint and validate against the monitor-reported range.
The comparison with ERROR_GRAPHICS_INVALID_MONITOR_FREQUENCYRANGE is especially useful: ERROR_GRAPHICS_INVALID_MONITOR_FREQUENCYRANGE rejects the underlying range record itself.
Recovery contract
Normalize units, range ordering and origin before pruning modes.
- debug-layer, ETW or driver diagnostics no longer report the rejected monitor timing constraint contract during the same scenario.
Implementation notes
Log source and target IDs, topology generation, path descriptors, pinned modes, mode-set handles and monitor timing data.
A production fallback should be explicit: pause rendering, re-enumerate, rebuild one cache entry, recreate a device, or decline a protected path only when this layer calls for that action. Reinstalling every display component, deleting all caches or forcing a resolution change is not an evidence-based fix.
