Multi-Monitor#
ExtraDock is built for multi-monitor setups. Each dock can be assigned to a specific display and remembers which screen it belongs to.
Allowed screens#
Open Management window → Properties → Position → Allowed Screens.
When no screen is assigned, the dock can appear on any screen.
Use Add Screen to limit the dock to one or more known screens. If you have multiple identical monitors, ExtraDock uses live connection details to keep them separate.
How assigned screens work#
- With Show on All Screens off, a dock appears on one allowed screen at a time
- If no assigned screen is connected, the dock hides
- When an assigned screen reconnects, the dock can return to it
Turn on Show on All Screens to mirror the same dock on every connected display. The dock keeps the same items and settings on each screen.
Duplicate a dock when you want separate items or settings on each display. Assign each copy to its own screen.
Forgetting screens#
Use Forget Screen to remove disconnected external displays from ExtraDock's known screen list. Built-in and currently connected screens cannot be forgotten.
Disconnect and reconnect#
ExtraDock uses stable display identifiers (based on vendor, model, and serial number) so your docks reliably return to the right screen — even after unplugging and replugging monitors.
