After updating to macOS, some users may notice slower mouse movement, display lag, or jitter on external monitors connected through a DisplayLink-based dock or graphics adapter. This behavior is typically related to driver compatibility or display configuration changes introduced with major macOS updates.
The steps below outline the most common ways to restore smooth performance.
1. Install the Latest DisplayLink Manager
Typically speaking, you will want to keep yourself updated with the most recent DisplayLink drivers. The most recent version of DisplayLink that we’ve tested with our devices can be found below.
However, in some instances, this will not be the most up to date version of DisplayLink. In instances where the version above does not help, you can look for a potentially newer version on DisplayLink’s website here: https://www.synaptics.com/products/displaylink-graphics/downloads/macos
Action:
- Visit the Plugable DisplayLink Drivers page
- Download and install the latest version of DisplayLink Manager for macOS (guides can be found for your specific version of macOS on the download page linked above)
- Restart your Mac after installation
2. Perform a Clean Installation of the DisplayLink Driver
If you upgraded macOS without removing the previous DisplayLink driver, leftover files can interfere with the new version.
Action:
- Download the DisplayLink Installation Cleaner from the Synaptics support site
- Run the cleaner tool to fully remove all DisplayLink components
- Restart your Mac
- Install the latest version of DisplayLink Manager
This clean installation process resolves the majority of display jitter and lag issues reported after macOS upgrades.
3. Verify External Display Refresh Rates
Many modern monitors default to high refresh rates such as 120Hz or 144Hz. While useful for gaming, higher refresh rates require more processing power when using USB-based video solutions like DisplayLink.
Action:
- Open System Settings
- Select Displays
- Choose each external monitor and set the refresh rate to 60Hz
Lowering the refresh rate significantly reduces CPU load and improves overall smoothness for office and productivity workloads.
4. Test with the Laptop Lid Open
On some MacBook models, closing the lid changes how macOS manages graphics resources. This can reduce available performance for external displays.
Action:
- Keep the MacBook lid open while using external monitors
- Check whether display responsiveness improves
If performance is better with the lid open, this configuration is recommended when using multiple external displays.
