STATUS_GRAPHICS_INVALID_PATH_CONTENT_TYPE
The present-path content type is invalid
STATUS_GRAPHICS_INVALID_PATH_CONTENT_TYPE is a Windows NTSTATUS value from the graphics/display facility. It belongs to the WDDM kernel display stack rather than to a Win32 GDI error alone, so the useful context is usually the adapter, VidPN object, child device, present path, or primary allocation involved in the call.
A VidPN present path has attributes that describe what kind of content is being displayed. This status means the content-type field on the path is not valid for the interface or path being configured.
This is a metadata validation failure. It is commonly caused by an uninitialized D3DKMDT field, a version mismatch, or copying a path attribute from a different display scenario. It should be diagnosed before checking mode timings or EDID details.
What to check
- Dump the path content type together with source ID, target ID, and path importance.
- Verify that the content type comes from the D3DKMDT VidPN present-path enum expected by this interface.
- Rebuild path attributes after clone/extend/topology changes rather than patching only the changed field.
