- Scenario
- Editing PDFs on a laptop connected to external monitors through a USB docking station.

Adjust Acrobat Display Preferences for Screen Resolution
Modifying how Acrobat handles screen scaling can prevent display mismatch issues on external monitors.
Launch Adobe Acrobat, click on 'Edit' in the top menu bar, and select 'Preferences' from the drop-down menu.
Navigate to the 'General' category on the left panel, locate the 'Scale for screen resolution' setting, and select 'No Scaling'.
Switch to the 'Page Display' category in the left panel, ensure 'Show Large Images' is checked under the Rendering section, and click 'OK'.
Update Graphics Card and Docking Station Drivers
Outdated display drivers or docking station firmware can cause rendering bugs when projecting to external monitors.
Isolate the Issue Across Files and Monitors
Determine whether the black band issue is specific to a single document or tied to a particular hardware connection.
Use WPS Office for Seamless PDF Editing on Any Monitor
If display bugs in Adobe Acrobat persist on your external monitors, consider switching to WPS Office. It offers a lightweight, highly compatible, and feature-rich PDF editor that works seamlessly across different screen resolutions and multi-monitor setups without rendering issues.
Frequently Asked Questions
Why do black bars appear on my monitor when using a docking station?
Black bars typically appear due to scaling mismatches between your laptop's integrated graphics, the docking station's drivers, and the software's DPI settings. Updating your drivers and disabling application-level scaling usually resolves this discrepancy.
Does the 'Scale for screen resolution' setting affect my PDF print quality?
No, changing the 'Scale for screen resolution' setting in Acrobat only affects how the application interface and document appear on your monitor. It does not alter the actual PDF file or degrade its print output quality.
What should I do if updating drivers doesn't fix the display issue?
If updating drivers doesn't help, try bypassing the USB docking station by plugging your monitor directly into your laptop's HDMI or DisplayPort. If the issue disappears, the docking station firmware may need an update or replacement.
