STATUS_GRAPHICS_INVALID_TOTAL_REGION
Total region includes visible and non-visible intervals
The total region describes the complete horizontal and vertical timing period, not just the visible picture. It includes active area together with blanking and synchronization intervals. This status therefore points to an impossible or inconsistent total timing definition.
It differs from an invalid active region: active pixels can be plausible while the proposed total is too small, uses the wrong unit, or cannot accommodate the required blanking and sync intervals. A cable or monitor replacement does not repair a malformed timing structure.
Validate before programming the path
- Compare total values with active values and ensure each total leaves a meaningful blanking interval where the timing format requires one.
- Check pixel-clock arithmetic and scan/interlace assumptions used to derive the totals.
- Preserve the original timing fields in diagnostics; a rounded “Hz” value alone is insufficient evidence.
