A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
Dear @Cook, Andrew (CEMSKAN),
Thank you for reaching out to Microsoft Q&A forum.
I understand you're experiencing an unexpected issue with Excel, where Freeze Panes causes a grey blank area to appear in the middle of your sheet. I attempted to replicate the issue in our test environment, and Freeze Panes worked as expected without any grey areas. Based on my research, this issue occurs when Excel is unable to properly manage two or more independent scrollable regions while Freeze Panes is active. If the graphics engine fails to redraw these regions quickly or encounters a calculation conflict, a grey void can appear where the grid should be.
Please try the following steps to see if it helps:
1.Toggle the "Optimize for Compatibility" Setting
- Go to File > Options > General.
- Under User Interface options, look for When using multiple displays.
- Select Optimize for compatibility (this will require an Excel restart).
- Test the sheet to see if the grey areas still appear during scrolling.
2.Perform a "Screen Refresh" via Zoom
If the grey area appears suddenly, you can often force Excel to redraw the grid without restarting:
- Press Ctrl + Mouse Wheel to zoom in and then zoom out.
- This forces the rendering engine to recalculate every visible cell on the screen.
3.Standardize Display Scaling
If you use multiple monitors:
- Right-click your Desktop and select Display settings.
- Ensure all monitors are set to the same Scale and layout percentage (e.g., all at 100% or 125%).
- Restart Excel after making this change.
Also, could you let me know if this issue occurs across all workbooks or only in one particular file? If it affects all workbooks, the issue may be related to your local hardware or Excel settings. However, if it’s happening with just one file, that file may need to be repaired.
I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this. Please note that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution. Thank you for your patience and understanding. I'm looking forward to your reply.
