monday.com Mirror Column empty? Check connections and permissions
Fix a blank monday.com Mirror Column by tracing linked items, source boards and viewing permissions while preserving intended access.
In this guide
First distinguish the connection from the displayed value
In monday.com, the Mirror Column displays selected information through a Connect Boards Column. Check the connected item, source board and chosen source column before treating a blank value as missing data.
For example, a project overview might connect to a customer record and display its status. If the wrong customer item is linked, the overview can be technically connected while showing the wrong business information. Confirm the identity of the record, not merely that a connection icon is present.
A visible destination board does not grant source access
monday.com’s permission explanation identifies missing access to connected boards and source-column viewing restrictions as reasons for hidden values. A person can open the overview board while being unable to view the data being mirrored.
Compare the affected person’s intended role with the source’s sensitivity. If the value is a confidential budget, hiding it may be correct. Ask the source owner to review the access requirement instead of publishing a private board or copying restricted data into an unrestricted text column.
Trace one value through the chain
Imagine a fictional delivery overview linked to a project board, which in turn refers to a commercial record. One manager sees the price; another sees an empty cell. Build a trace showing the destination item, each connected source and the field being reflected. Review each boundary with the relevant owner.
That trace separates three questions: does the source contain a value, is the intended item connected, and may this viewer read it? Solving only the final display cannot answer all three. Use a harmless field for a demonstration if the actual price is restricted.
Use a focused troubleshooting record
| Layer | Question | Next owner |
|---|---|---|
| Destination item | Is the intended item linked? | Board maintainer |
| Source value | Does the selected field contain the expected data? | Record owner |
| Board access | May this viewer access every required source? | Source board owner |
| Column access | Is this field visible to this role? | Permissions administrator |
Keep an expected result for each viewer. A correct fix can be leaving the restricted value hidden and using a different authorised summary for the overview. Do not make the most privileged viewer’s screen the default acceptance standard.
Verify updates without broadening the audience
In an authorised pilot, connect one synthetic record, change an ordinary status and check what the intended viewer sees. Where editing through the mirror is required, test that exact field and permission arrangement. A displayed value does not establish every editing, automation or summary behaviour.
Record the actual field type, board settings and retained plan before expanding the pattern. Use the monday.com profile for the wider shortlist and the project trial checklist to compare ownership and reporting. A complete-looking dashboard is useful only when the data is correctly linked and appropriately visible.
Frequently asked questions
Why can one monday.com user see mirrored data while another cannot?
Check each person’s access to the connected source boards and the relevant source-column viewing permissions.
Does opening an overview board give access to all mirrored sources?
No. Destination-board access does not by itself grant permission to view the source data.
What should I check before changing Mirror Column permissions?
Confirm the intended linked item, source board and field, then have the source owner review the viewer’s legitimate access requirement.
