ERROR_GRAPHICS_INVALID_VIDPN_TOPOLOGY
ERROR_GRAPHICS_INVALID_VIDPN_TOPOLOGY (0xC0262300) means the requested Video Present Network (VidPN) topology is structurally invalid. A VidPN describes how display sources, targets, paths, and mode sets are connected.
What to check
- Re-enumerate the current topology after monitor hot-plug, docking, GPU switch, or session change.
- For driver development, validate every source-target path and mode-set association before returning the topology.
- Do not reuse a topology object that was obtained before a display configuration change.
