Use this when the installed Duet Display driver is the implicated DDKMD.SYS component. Ensure that a working primary display remains available before removal.
- Duet Display's DDKMD.SYS caused black-screen behavior and SYSTEM_SERVICE_EXCEPTION during display-related actions.
- Uninstalled Duet Display and its display driver.
Reported outcome: The affected applications worked and the former trigger no longer crashed Windows.
Record the installed package/version and retain the compatible installer. Test the same display action after restart; if the failure remains, preserve the dump and investigate its named driver rather than removing unrelated display software.
