How to Fix Power Query Editor Display Scaling After an Excel Update
Question details
The user needs to fix an issue where the Power Query Editor appears extremely zoomed in, even though the main Excel application displays correctly.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Opening the Power Query Editor in Excel after a recent update, particularly when using high-resolution laptop screens or multiple monitor setups.
- Observed behavior
- The Power Query Editor interface becomes abnormally large and zoomed in, causing UI elements to overlap or become difficult to navigate, while main Excel windows remain unaffected.
Ensure all your current Excel workbooks are saved, as you will need to completely restart the Excel application to apply the display compatibility settings.
Enable Optimize for Compatibility in Excel Options
Adjusting Excel's built-in user interface options changes how display scaling is handled, correcting the DPI mismatch between Excel and the Power Query Editor.
By default, Excel optimizes for the best appearance on high-resolution screens. However, after certain updates, this can cause auxiliary windows like the Power Query Editor to scale incorrectly. Switching the setting to optimize for compatibility forces standard scaling across all Excel-related windows.
Launch Microsoft Excel. Click on the 'File' tab in the top-left corner of the ribbon, and select 'Options' located at the very bottom of the left-hand menu.
In the Excel Options dialog box, ensure you are on the 'General' tab. Under the 'User Interface options' section, select the radio button for 'Optimize for compatibility'.
Click 'OK' to save your changes. Close all open Excel windows completely, and then restart Excel. Launch the Power Query Editor to confirm the zoom issue is resolved.

Standardize Windows Display Scaling Across Monitors
If you use multiple monitors, matching the display scaling percentage across all screens can prevent scaling glitches when moving the Power Query Editor between them.

Frequently Asked Questions
Why is only the Power Query Editor zoomed in and not the rest of Excel?
The Power Query Editor runs as a separate graphical interface within Excel. Following certain Office updates, its DPI (Dots Per Inch) scaling handling can fall out of sync with the main Excel application, causing it to misinterpret the screen's resolution and enlarge the interface excessively.
Will optimizing for compatibility affect how my spreadsheets look?
Enabling 'Optimize for compatibility' changes how Excel renders on different displays. While it effectively fixes scaling bugs for external windows, it may make fonts, icons, or the ribbon look slightly less crisp on high-DPI displays compared to the 'Optimize for best appearance' setting.
What should I do if the compatibility setting doesn't fix the Power Query zoom issue?
If the problem persists, try updating your graphics card drivers, standardizing your Windows display scaling to be identical across all monitors, or rolling back your Microsoft Office installation to a previous version until Microsoft releases a patch for the specific update.
