STATUS_GRAPHICS_ADAPTER_CHAIN_NOT_READY
The linked-adapter chain is not ready
STATUS_GRAPHICS_ADAPTER_CHAIN_NOT_READY is a Windows NTSTATUS value from the graphics/display facility. For STATUS_GRAPHICS_ADAPTER_CHAIN_NOT_READY, 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 status is broader than a single missing link. It says the chain of linked display adapters cannot be used yet because the combined configuration is not ready to start or perform the requested operation.
Look at the chain as a state machine: enumeration, start, power, POST ownership, and link-state consistency all matter. A failure on one link can cause the lead adapter to report the chain as not ready even when other links look healthy.
What to check for STATUS_GRAPHICS_ADAPTER_CHAIN_NOT_READY
- Collect per-link enumeration, start, power, and driver status before looking at VidPN details.
- Check for earlier statuses such as chain links not enumerated, not started, or not powered on.
- Do not retry topology commits until the chain state becomes coherent.
