STATUS_GRAPHICS_MULTISAMPLING_NOT_SUPPORTED
Multisampling is not available on this present path
STATUS_GRAPHICS_MULTISAMPLING_NOT_SUPPORTED is a Windows NTSTATUS value from the graphics/display facility. For STATUS_GRAPHICS_MULTISAMPLING_NOT_SUPPORTED, 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.
This graphics status indicates that multisampling cannot be used for the current VidPN present path. It is a path capability issue, not necessarily a failure of the GPU to render multisampled resources in other contexts.
The diagnostic distinction matters in hybrid graphics, remote/indirect display, protected output, or unusual primary-surface paths. Rendering support in Direct3D does not automatically imply support for the display path that is being configured by the kernel display manager.
What to check for STATUS_GRAPHICS_MULTISAMPLING_NOT_SUPPORTED
- Log the source, target, path content type, pixel format, and multisampling parameters.
- Check whether the operation is for primary presentation rather than off-screen rendering.
- Test the same format and mode without multisampling before changing monitor or topology assumptions.
