STATUS_GRAPHICS_LEADLINK_START_DEFERRED
Starting the lead link is deferred
STATUS_GRAPHICS_LEADLINK_START_DEFERRED is a Windows NTSTATUS value from the graphics/display facility. For STATUS_GRAPHICS_LEADLINK_START_DEFERRED, 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.
Linked display-adapter configurations have ordering requirements: a lead link and one or more chain links must be enumerated, started, and powered consistently. This status is informational and means the lead link start has been postponed rather than completed immediately.
The useful distinction is temporary deferral versus permanent link failure. A deferral often appears while PnP or power state for the chain is still converging. If it persists, inspect enumeration of every link in the chain, power-on order, and whether the adapter actually belongs to a linked configuration.
What to check for STATUS_GRAPHICS_LEADLINK_START_DEFERRED
- Record the link role, adapter LUID, PnP state, and power state for every link in the chain.
- Do not attempt VidPN commit work that assumes the lead link has already started.
- If the status repeats, look for a missing chain-link start or inconsistent PnP/power transition.
