In this article, we will discuss some troubleshooting steps to help you resolve this issue and get your external screens working properly.

Check System Requirements

Before diving into troubleshooting, it is important to ensure that your system meets the necessary requirements for DisplayLink Flux to work properly. Here are the minimum requirements:

Update DisplayLink Driver

One common reason for DisplayLink Flux not working is an outdated driver. To update the DisplayLink driver on your MacOS device, follow these steps:

1. Visit the official DisplayLink website and navigate to the "Downloads" section.
2. Locate the latest driver for MacOS and download it to your computer.
3. Once the download is complete, double-click on the installer package to begin the installation process.
4. Follow the on-screen instructions to complete the installation.
5. Restart your computer after the driver installation is finished.

Check Display Settings

If updating the driver did not resolve the issue, it is important to check your display settings to ensure they are properly configured. Follow these steps:

1. Click on the Apple menu in the top-left corner of your screen and select "System Preferences".
2. In the System Preferences window, click on "Displays".
3. Ensure that your external screen is detected and selected as the primary display.
4. Click on the "Arrangement" tab and make sure the "Mirror Displays" option is unchecked.
5. Try disconnecting and reconnecting the external screen to see if it resolves the issue.

Reset PRAM and SMC

If the above steps did not resolve the issue, resetting the PRAM (Parameter Random Access Memory) and SMC (System Management Controller) on your MacOS device may help. Here's how to do it:

1. Shut down your Mac.
2. Press the power button and immediately hold down the Command, Option, P, and R keys simultaneously.
3. Keep holding the keys until your Mac restarts and you hear the startup sound for the second time.
4. Release the keys and allow your Mac to boot up normally.
5. If the issue persists, you may need to reset the SMC. Shut down your Mac again.
6. Press and hold the power button for 10 seconds, then release it.
7. Wait for a few seconds and then press the power button again to turn on your Mac.

Check Cable and Connections

Another possible cause for DisplayLink Flux not working is a faulty cable or loose connection. Follow these steps to check your cable and connections:

1. Inspect the cable connecting your Mac to the external screen for any visible damage.
2. If possible, try using a different cable to connect your Mac to the external screen.
3. Ensure that the cable is securely plugged into both your Mac and the external screen.
4. Try connecting the external screen to a different port on your Mac, if available.

Disable Third-Party Applications

In some cases, third-party applications or conflicting software can interfere with the proper functioning of DisplayLink Flux. To troubleshoot this, follow these steps:

1. Quit all third-party applications running in the background.
2. Restart your Mac and try using DisplayLink Flux again.
3. If the issue is resolved, you can identify the problematic application by gradually reopening your applications until the issue reoccurs.
4. Once you have identified the problematic application, check for any updates or contact the application's support for further assistance.

Contact Support

If none of the above steps resolve the issue, it is recommended to contact DisplayLink support or the manufacturer of your external screen for further assistance. They will be able to provide you with specific troubleshooting steps or help you determine if there is a hardware issue.
