A boundary, not an omission to guess around.

Attaching a saved brief retains a snapshot. It does not edit the brief, approve a connection, refresh a source or establish that equipment is safe.

Before you connect

What to check

Use Windows + P to inspect the selected mode. Choose the mode that fits your intended use, then record the result.
Check the external display cable without forcing or opening anything. Record any damage as a stop condition.
Where the device manuals permit it, compare without a dock or extra adapter. Safely eject unrelated storage first.
A suitable known-working cable or display connection can provide a comparison. Record exactly what changed; do not assume it proves a fault.
List the current OS, equipment, connection path and results. Escalate rather than uninstalling drivers through this tool.
