STATUS_GRAPHICS_INVALID_VIDEO_PRESENT_SOURCE_MODE
Source mode describes the logical image producer
A source mode belongs to the video present source and represents how the graphics side of a display path produces content. This status means that selected source-mode descriptor is invalid in the current VidPN context. It is more specific than an invalid source ID and different from a target signal timing failure.
Source modes are constrained by topology and other pinned choices. A source mode that existed in a previous configuration is not automatically valid after a topology change, a source-mode-set replacement, or a resource transition.
Trace the source-side choice
- Log source ID, source mode-set identity, format, dimensions, multisampling information, and whether the mode is pinned.
- Confirm that the mode came from the current source mode set rather than a cached prior enumeration.
- Compare with
STATUS_GRAPHICS_INVALID_VIDEO_PRESENT_TARGET_MODEbefore changing output timing fields.
