Why do some sheets have a fuzzy/blurry view and erratic cell selection until a slight scroll is done?

Hi @Craig Gerdes

Thank you for posting your question in the Microsoft Q&A forum. To make sure I understand your request:

• Have you noticed if the issue occurs more frequently after performing specific actions, such as switching sheets or pasting data?
• Are you using multiple monitors or a high-resolution display setup?
• Do you have any add-ins enabled in Excel that might be affecting its performance?
• Are you using Excel on one monitor or multiple screens?
• Does this happen with all workbooks or only ones copied from your colleague?
• What version of Excel are you using?

In the meantime, I would recommend some steps you could try:

1. Scroll Slightly
   You mentioned scrolling helps. This suggests a display rendering issue.
2. Adjust Excel Display Option
   Go to File > Options > General > User Interface
   Under “When using multiple displays,” select Optimize for compatibility.
   Restart Excel. If already set to compatibility, try switching to Optimize for best appearance and restart again.
   This toggles Excel’s rendering mode and may eliminate the blur.
3. Check Display Scaling
   If using multiple monitors, make sure they use the same scaling percentage (e.g., 100% on both).
4. Test Freeze Panes
   Go to View > Freeze Panes > Unfreeze Panes.
   If the issue clears up, this may be the trigger. You can leave panes unfrozen or reapply later.
   As a workaround, consider using an Excel Table to keep headers visible without freezing.
5. Start Excel in Safe Mode
   • Hold Ctrl while launching Excel or run excel.exe
   • Open the affected workbook. If the issue doesn’t appear, a COM add-in may be causing it.
   • Disable add-ins one by one via File > Options > Add-Ins > COM Add-ins and restart Excel each time to test.
     Focus on add-ins like Power Map, Power Pivot, or Data Streamer.
6. Repair Office
   Go to Control Panel > Programs >Programs and Features > Microsoft 365 Apps. > Click-right and choose Change.
   

Choose Quick Repair to fix any corrupted components.
