Start with the difference that matters
A docked laptop may change resolution routinely, while removal of its external monitor is unusual. One useful configuration is to react to monitor removal but ignore layout changes. Another is to monitor all three while the machine is locked and leave them alone while you work.
- Open Triggers for normal armed behavior, or Windows locked for independent locked-session behavior.
- Choose separate actions for Monitor connected, Monitor disconnected and Resolution/layout changed.
- For a narrow example, set the two monitor rows to Restart and the layout row to Do nothing.
- If editing the locked profile, check Monitor while Windows is locked and review its other rows before saving.
Test each change on its own
In a dry-run session, first change the display arrangement or resolution using Windows settings. Then separately connect and remove a spare display. Open Event history and compare the reported event types. Use Test monitoring.cmd when testing a locked-only setup, and manually lock Windows for that part of the check.
Changing one cable can also alter the desktop layout. Seeing both entries is expected on some hardware. Distinct settings give you control over each reported event; they do not guarantee that a physical action produces only one notification.
Know which profile wins
When the locked profile is enabled and Windows is locked, its Do nothing choice suppresses the normal action for that event. It does not inherit the normal rule. When the locked profile is off, an armed normal profile may still respond using its own display rules.
Driver behavior determines whether a particular event reaches the app. Treat a missing event as a setup limitation to investigate, not proof that no physical change happened. See a monitor-removal walkthrough and how to interpret event history.
