How to Fix Excel Freezing with Different Scaling on Multiple Monitors
Question details
The user experiences Microsoft Excel freezing and displaying a blank security notification when moving between multiple monitors with different display scaling settings.
- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Using a laptop with an external monitor where display scaling is set to 150% on one screen and 100% on the other.
- Observed behavior
- Excel freezes and shows a blank security dialog. The application works normally when both monitors are set to the exact same scaling percentage or when Excel is launched in Safe Mode.
Ensure you have saved all open workbooks and close any unsaved background applications, as you may need to restart your computer after adjusting system display settings.
Match Display Scaling on All Monitors
Setting the display scaling to be identical across all connected monitors is the most reliable workaround to prevent Excel from freezing during monitor transitions.
Right-click on an empty space on your Windows desktop and select 'Display settings' from the context menu.
Click on your first monitor at the top of the settings window, then scroll down to the 'Scale and layout' section and note the percentage under 'Change the size of text, apps, and other items'.
Click on your second monitor and use the dropdown menu to set it to the exact same percentage (e.g., 100% or 125%) as the first monitor.
Restart your computer to ensure Windows and Microsoft 365 applications properly re-render the interface with the synchronized scaling settings.
Disable Hardware Graphics Acceleration and Add-ins
If changing display scaling isn't ideal for your setup, disabling hardware acceleration and problematic add-ins can sometimes resolve the display compatibility conflict in Excel.
Update Windows, Office, and Graphics Drivers
Different per-monitor scaling may expose an underlying display bug. Updating your system components can resolve known compatibility issues.
Try WPS Office for Stable Multi-Monitor Performance
If Microsoft Excel continues to freeze across multiple monitors with different scaling settings, consider switching to WPS Office. It provides a lightweight, highly optimized experience that handles complex multi-monitor setups without display-related crashes.
Frequently Asked Questions
Why does Excel freeze when I move it to a second monitor?
Excel may freeze or display blank dialog boxes when moving between monitors if they use different display scaling settings (e.g., 150% on a laptop and 100% on an external monitor). This is often due to a display rendering conflict within Windows or Office when recalculating the interface dimensions.
Can accessibility settings cause Microsoft 365 applications to freeze?
Yes. Resetting or heavily modifying Windows accessibility text-size settings can affect how Microsoft 365 applications render dialog boxes, potentially leading to blank security notifications or application freezing.
Do I need to restart my PC after matching display scaling?
Yes. While Windows applies scaling changes immediately, many applications (including Microsoft Office) require a full system restart, or at least signing out and signing back into your Windows user profile, to render correctly without graphical bugs.
How do I test if an add-in is causing Excel to freeze?
Press the Windows key + R, type 'excel /safe', and press Enter. If Excel works perfectly on both monitors in Safe Mode, the freezing is likely caused by an installed add-in. You can disable add-ins one by one via File > Options > Add-ins to identify the culprit.
