What Are Mirror Columns in Monday.com?
Having a single source of truth in your workflow is paramount to being efficient and accurate. But there may be situations where we need to see that information in multiple boards. Rather than having to enter it twice (cringe!) or set up a cross-board automation (inefficient), monday.com has the Mirror column feature.
A mirror column (added via a ‘connect boards’ column) is a portal into another board. The column and cells will display the same information on both of the connected boards—change the data in one board and it’s instantly updated in the other board—no automations or ‘forgot to update both boards’ here!
How Mirror Columns Work: Real-Time Data Synchronization
Monday.com mirror columns create a live connection between boards, enabling real-time data synchronization without duplication. This powerful feature ensures:
- Automatic updates across all connected boards
- Zero manual data entry redundancy
- Instant visibility of changes across your workflow
- No automation setup required
- Single source of truth maintained across multiple views
Key Benefits of Mirror Columns:
- Eliminate duplicate data entry and human error
- Save time with automatic synchronization
- Maintain data accuracy across all boards
- Improve collaboration with shared information
- Create custom views without compromising data integrity
Multi-Board Mirror Columns: The Ultimate Overview Tool
Ready to up your game and bring a new level of visibility to your higher-level boards? The Multi-board mirror column takes the power of mirror columns to the next level.
What Are Multi-Board Mirror Columns?
Added the same way as a mirror column from a “connect multiple boards” column, now you can select multiple boards and have information from a group of boards all pulled into the same place. This is a super powerful tool for high-level overview boards, executive dashboards, and portfolio management.
After connecting your boards you can select which columns in those boards you want to see, giving you complete control over what information appears in your consolidated view.

Best Practices for Using Mirror Columns
1. Maintain Your Single Source of Truth
Building a workflow with a single source of truth is undeniably best practice, and mirror columns let you see and edit that single-ful source-iness from whatever board you’re in.
2. Use Descriptive Column Names
When setting up mirror columns, use clear naming conventions so team members understand where the data originates.
3. Limit Multi-Board Mirrors for Performance
While powerful, connecting too many boards in a single multi-board mirror can slow performance. Focus on essential data only.
4. Combine with Dashboards
Use mirror columns alongside monday.com dashboards for the ultimate combination of detailed data access and visual analytics.
5. Document Your Connections
Keep track of which boards are connected via mirrors, especially in complex workflows with multiple dependencies.
Mirror Columns vs. Automations: When to Use Each
While cross-board automations can move or copy data between boards, they’re less efficient than mirror columns for viewing synchronized data:
- Use Mirror Columns when: You need real-time visibility of data across boards
- Use Automations when: You need to trigger actions or create independent copies of data
Troubleshooting Common Mirror Column Issues
Mirror Column Not Updating?
- Check that the connect boards column is properly linked
- Verify you have edit permissions on both boards
- Refresh your browser to see the latest changes
Can’t See All Boards?
- Ensure you have access permissions to the boards you want to connect
- Check if boards are in different workspaces
Too Much Data Displayed?
- Use board views and filters to narrow down visible items
- Consider creating multiple focused mirror columns instead of one comprehensive view
