Question details
The user needs to fix an issue where PDF file previews appear cut off or truncated when viewed in Microsoft Outlook on a secondary monitor.
- Product
- Microsoft Outlook and Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Viewing PDF email attachments using the built-in preview pane in Microsoft Outlook while the application window is displayed on an extended or secondary monitor.
- Observed behavior
- The PDF preview does not scale correctly and appears truncated, hiding parts of the document in the Outlook preview pane.
Save your current work and close both Microsoft Outlook and Adobe Acrobat completely to ensure changes to settings or updates take effect properly.
Update Outlook and Acrobat
Installing the latest software updates often resolves known preview handler and scaling bugs between Acrobat and Outlook.
Software updates frequently contain patches for display anomalies. Ensure both your email client and PDF viewer are running the latest versions.
Open Outlook, go to File > Office Account > Update Options, and click 'Update Now' to install any pending Office updates.
Launch Adobe Acrobat, navigate to the Help menu at the top, and select 'Check for Updates'. Follow the on-screen prompts to install patches.
After both applications have been updated, reboot your computer or restart both applications and move the Outlook window to the second monitor to test the preview.
Adjust Windows Display Scaling
Mismatched display scaling between your primary and secondary monitors can cause the PDF previewer to render incorrectly.
Update Graphics Drivers
Outdated display drivers can cause hardware-accelerated elements like PDF previews to truncate on extended displays.
Experience Flawless Document Viewing with WPS Office
If third-party preview handlers in Microsoft Outlook continue to struggle with multi-monitor scaling, consider using WPS Office. It is a free, lightweight suite with a built-in PDF reader that ensures stable, accurately scaled document viewing across all your monitors, without relying on external plugins.
- 1. Download the installer: Visit the official WPS website and download the free WPS Office suite.
- 2. Install and set as default: Run the installer and optionally set WPS Office as your default application for handling PDF and Office documents.
- 3. View documents seamlessly: Open your PDFs directly in WPS Office for a stable, correctly scaled reading experience on any monitor.
Frequently Asked Questions
Why does the PDF preview only truncate on my second monitor?
This is usually caused by mismatched DPI (Dots Per Inch) scaling between your primary and secondary monitors. The preview handler plugin struggles to dynamically resize its content when dragged to a screen with a different scaling percentage.
Can I change the default PDF preview handler in Outlook?
Yes. If you install a different PDF viewer (like WPS PDF) and set it as your system's default PDF application, Outlook will typically use that software's preview handler instead of Adobe Acrobat's, which may bypass the scaling issue.
How do I test if the issue is monitor-specific?
Drag the Outlook window to your primary monitor and click on the PDF attachment. If the preview displays correctly on the main monitor but truncates on the second, the issue is directly related to multi-monitor scaling or display drivers.
Will disabling hardware acceleration in Acrobat fix the preview?
Sometimes. You can try opening Adobe Acrobat, going to Edit > Preferences > Page Display, and unchecking 'Use 2D graphics acceleration'. Restart Outlook afterward to see if the preview rendering improves.
