STATUS_GRAPHICS_POLLING_TOO_FREQUENTLY
Child-device polling was throttled
STATUS_GRAPHICS_POLLING_TOO_FREQUENTLY 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.
Windows may poll display children when it needs current connector status, especially for outputs that report hot-plug presence by polling rather than interrupts. This status means the polling request rate is too high for the current level and the display stack is throttling repeated polls.
The problem is usually a caller loop or UI/service component repeatedly forcing display detection, not a monitor timing problem. Polling can be nondestructive or potentially destructive depending on parameters, so aggressive retries can cause visible artifacts and unnecessary driver work.
What to check
- Log the polling flags, adapter handle, child count, and time since the previous poll.
- Avoid tight retry loops after display-change notifications; wait for a real topology or child-status event.
- Prefer interrupt-driven HPD paths when the child device reports HpdAwarenessInterruptible.
