- 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.
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.
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.
Open Microsoft Excel on your primary monitor and keep the Power Query Editor on this display rather than dragging it to a secondary screen.
If the dialog box is currently hidden or distorted, unplug secondary monitors to force the Power Query window back to the main screen.
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.
Disable Conflicting Excel Add-ins
Third-party Excel add-ins can occasionally interfere with the graphical rendering of the Power Query Editor.

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.
