Override High DPI Scaling Settings for OneNote

Modifying the compatibility properties of the OneNote executable forces Windows to handle application scaling properly on 4K monitors, resolving the blurriness.

This is the most effective solution for desktop versions of Office applications that do not dynamically scale well with custom Windows display settings.

Locate the OneNote executable file

Open File Explorer and navigate to your Office installation folder, typically located at C:\Program Files\Microsoft Office\root\Office16.

Open application properties

Find the ONENOTE.EXE file, right-click on it, and select 'Properties' from the context menu.

Access compatibility settings

Switch to the 'Compatibility' tab located at the top of the Properties window.

Change high DPI settings

Click the 'Change high DPI settings' button. Check the box that says 'Override high DPI scaling behavior', and select 'System (Enhanced)' from the 'Scaling performed by:' drop-down menu.

Apply and restart

Click 'OK' to apply the new settings, and then restart OneNote to see the crisp, updated display.

Version Variations: The exact installation path to ONENOTE.EXE may vary slightly depending on whether you are using a 32-bit or 64-bit version of Windows and Office, or a different yearly release of the suite.

Solution 2

Frequently Asked Questions

Why do some older Office apps look blurry on a 4K monitor?

Older applications may not fully support the dynamic high-DPI scaling introduced in newer versions of Windows. When the OS attempts to scale up an unsupported app to make it readable on a 4K screen, it essentially stretches the interface like an image, resulting in a blurry or pixelated appearance.

Can I fix display scaling issues for all Microsoft Office applications at once?

Yes, you can apply the same 'Override high DPI scaling behavior' fix to other Office executables, such as WINWORD.EXE (Word) or EXCEL.EXE, found in the same installation folder. Alternatively, adjusting your primary Windows Display scaling percentage to a recommended default (e.g., 150% or 200%) in System Settings can help universally.

What should I do if the Compatibility tab is missing for OneNote?

If you are using the Microsoft Store version (OneNote for Windows 10), the executable properties are managed directly by Windows and will not show a Compatibility tab. In this case, you cannot manually override the DPI settings. Ensure your Windows OS and the OneNote app itself are fully updated through the Microsoft Store to receive automatic scaling fixes.
