How to Fix Power Query Dialog Box Display Issues in Excel
Product
Microsoft 365 Excel
Device & OS
not provided
Scenario
Working with Power Query Editor while using multiple monitors, varying graphics settings, or custom display scaling.
Observed behavior
The Power Query Editor window appears incomplete, distorted, or completely fails to display correctly on the screen.
Before you start

Ensure your Windows display scaling is set to the recommended percentage for your primary monitor, and save any active work in Excel to prevent data loss before adjusting display settings or restarting.

Solution 1Recommended

Adjust Monitor and Display Configuration

Resolves rendering conflicts caused by moving the Power Query Editor across multiple monitors with different scaling or resolutions.

Microsoft Excel sometimes struggles to render modal windows properly when they are moved between screens with distinct scaling settings. Keeping the window on the primary display usually prevents these visual bugs.

1
Use the primary monitor

Open Microsoft Excel on your primary monitor and keep the Power Query Editor on this display rather than dragging it to a secondary screen.

2
Temporarily disconnect extra monitors

If the dialog box is currently hidden or distorted, unplug secondary monitors to force the Power Query window back to the main screen.

3
Avoid lock and sleep modes

Do not let your computer enter sleep mode or lock the screen while the Power Query Editor is actively open, as waking the PC can corrupt the dialog box UI.

Power Query and AutoSave: Leaving the Power Query Editor open may also temporarily block AutoSave to OneDrive, SharePoint, or Teams. Close the editor to resume syncing.

Frequently Asked Questions

Why does the Power Query Editor disappear when my computer wakes from sleep?

Excel sometimes fails to correctly re-render modal dialog boxes like Power Query after waking from sleep or lock mode due to graphics driver handoffs. It's recommended to save your work and close the editor before locking your PC.

Will changing my display scaling fix the Power Query dialog box?

Yes. If your monitors have different scaling settings (e.g., 100% on one and 150% on another), dragging the window between them can cause severe graphical glitches. Setting both monitors to the same scaling percentage in Windows Display Settings often resolves this.

Does Power Query block the Excel AutoSave feature?

Yes, having the Power Query Editor actively open will temporarily pause or block AutoSave to cloud locations like OneDrive, SharePoint, or Microsoft Teams until the editor window is closed.
