Field report: with Exclusive Topology, the physical monitor sometimes stayed lit — every isolate attempt re-committed and failed SetDisplayConfig with 0x57 ERROR_INVALID_PARAMETER. Clearing DISPLAYCONFIG_PATH_ACTIVE alone leaves the deactivated path's source/target modeInfoIdx pinned to the queried mode entries, and per the SetDisplayConfig contract a path being turned off must have BOTH mode indexes set to DISPLAYCONFIG_PATH_MODE_IDX_INVALID; some driver/topology combinations (notably when the doomed path shares a source with the kept virtual path) reject the supplied config outright, so the retry loop could never converge.
