How to Fix Incorrect OneNote Display Scaling on Multiple Monitors
Question details
The user needs to correct a display scaling issue where the application window resizes incorrectly when moved between different monitors.

- Product
- Microsoft OneNote
- Device & OS
- Surface Pro 9
- Scenario
- Moving the application window between a primary device screen and an external widescreen monitor.
- Observed behavior
- OneNote appears too small on the Surface Pro 9 display and too large on the widescreen monitor. The issue affects only one specific user account and persists even after reinstalling Microsoft 365.
Before reaching out to support, verify your Windows Display settings by navigating to Settings > System > Display to ensure the scale and layout percentages are set to the recommended values for both of your screens.
Contact Microsoft 365 Support for Account-Specific Diagnostics
Because the scaling issue is isolated to a single user account and a specific app (OneNote), it requires backend investigation and diagnostic logs rather than a simple software reinstall.
When an issue affects only one user profile and persists through a complete reinstallation of Microsoft 365, the root cause often lies in a corrupted cloud-synced account setting or a backend configuration error. Local troubleshooting is usually insufficient for these edge cases.
Document your exact Windows build version, the specific Microsoft 365 subscription tier, and take screenshots or a video of the OneNote window changing size when dragged across monitors.
If you are using a work or school account, reach out to your internal IT helpdesk. They can access the Microsoft 365 Admin Center to check for account-level sync issues or recreate your local user profile.
If you are the administrator or using a personal account, go to the Microsoft 365 Admin Center or Microsoft Support portal. Click on 'Support' > 'New service request', and provide the gathered details so they can initiate a remote assistance session and collect diagnostic logs.

Frequently Asked Questions
Why do apps change size when moved between monitors?
Monitors often have different DPI (Dots Per Inch) scaling settings and resolutions. Windows attempts to dynamically resize the application window to match the target monitor's scaling setting. If the application struggles with dynamic DPI scaling, it may appear disproportionately large or small.
Can I manually adjust the scaling for just my external monitor?
Yes. Right-click your desktop and select 'Display settings'. Click on the rectangle representing your external monitor, scroll down to the 'Scale and layout' section, and choose a different percentage from the 'Scale' dropdown menu.
What does it mean if an issue affects only one user account?
It typically indicates that the software installation itself is healthy, but the user's specific profile registry keys, temporary files, or cloud-synced preferences are corrupted. This is why reinstalling the software globally usually does not resolve the problem.
