How to Fix Dotted or Broken Lines in Microsoft Office
Question details
The user is experiencing unexplained dotted or broken lines across multiple Microsoft Office applications that standard troubleshooting steps have not resolved.
- Product
- Microsoft Office
- Device & OS
- not provided
- Scenario
- Viewing or editing documents in Microsoft Office desktop applications.
- Observed behavior
- Persistent dotted or broken lines appear on the screen, which are unrelated to page breaks, shapes, or formatting marks, and persist even after reinstalling or repairing the software.
Ensure your computer's operating system is fully up to date and save any open documents before modifying system display settings or updating graphics drivers.
Disable Hardware Graphics Acceleration in Office
Turning off hardware acceleration forces Office to rely on software rendering, which often resolves display artifacts like dotted or broken lines caused by GPU conflicts.
Microsoft Office utilizes your computer's graphics card to render documents faster and smoother. However, if there is a conflict between the application and the graphics driver, visual glitches can occur.
Launch any affected Office application (such as Word or Excel). Click on 'File' in the top-left corner, and then select 'Options' at the bottom of the left-hand menu.
In the Options dialog box, click on 'Advanced' in the left pane.
Scroll down to the 'Display' section. Check the box that says 'Disable hardware graphics acceleration'. Click 'OK' to save your changes.
Close and reopen the Microsoft Office application to see if the dotted lines have disappeared.
Update Your Display Adapter Drivers
Outdated or corrupted graphics drivers can cause persistent rendering issues across desktop applications, requiring a driver update.
Troubleshoot Hardware and Monitor Connections
If software settings do not fix the problem, the lines might be a physical hardware defect with the monitor or display cable.
Try WPS Office for a Glitch-Free Document Experience
If Microsoft Office continues to display rendering issues or visual artifacts, consider switching to WPS Office. It provides a lightweight, highly compatible alternative that handles Word, Excel, and PowerPoint files flawlessly without heavily taxing your computer's graphics hardware.
- 1. Download WPS Office: Visit the official WPS website and download the free installation package for your operating system.
- 2. Install and Set as Default: Run the installer and follow the prompts. You can choose to set WPS Office as the default application for opening documents.
- 3. Open Your Files: Double-click your existing Microsoft Office files to open them seamlessly in WPS Office without visual glitches.
Frequently Asked Questions
Why do these dotted lines only appear in Microsoft Office applications?
Office applications often use hardware graphics acceleration to render fonts, shapes, and animations more smoothly. If your graphics card or its driver has a compatibility issue with this feature, visual artifacts like dotted lines can appear exclusively within these apps.
Will reinstalling Microsoft Office fix the broken lines?
Often, no. Because the issue is typically rooted in how the software interacts with your computer's graphics hardware, simply reinstalling Office won't change the underlying hardware acceleration settings or update your graphics driver.
Where can I find the 'Disable hardware graphics acceleration' option in newer Office versions?
In some newer versions of Microsoft 365, Microsoft has removed this specific checkbox from the Options > Advanced menu. Instead, you may need to rely on updating your computer's graphics drivers or modifying application rendering settings directly in your graphics card control panel (such as NVIDIA Control Panel or AMD Software).
