If you're experiencing display issues or other problems with a Plugable device that uses Silicon Motion technology (such as certain USB video adapters or docking stations), performing a full uninstall and reinstall of the software often resolves the issue. Below are step-by-step instructions for both Windows and macOS systems.

For Windows Systems

1. Disconnect the Dock or Adapter
   Unplug your Plugable USB video adapter or docking station. If the product you are using has an external power adapter (for example a USB docking station), please also disconnect the power adapter from the product so that the unit resets. Please keep everything disconnected until prompted.

2. Uninstall the Software
   Open the Control Panel > Programs and Features, then locate and uninstall "Silicon Motion USB Display Driver." Note: Microsoft offers a quick guide on how to do this on both Windows 10 and 11 here. 

3. Restart the Computer (even if unprompted)
   This helps ensure a clean state for reinstallation
4. Reinstall the Software
   Download the latest version of the InstantView software for your version of Windows here.
5. Reconnect the Dock or Adapter
   Plug the device back in and verify that displays or other peripherals are now working correctly.

For macOS Systems

1. Disconnect the Dock or Adapter
   Unplug any Plugable device that uses Silicon Motion (e.g., USB video adapters or docking stations)
2. .Open Finder
   Click on the Finder icon on your desktop.
3. Navigate to the Applications Folder
   In the Finder sidebar, select Applications and look for an app named Silicon Motion InstantView (or similar).
4. Run the Uninstaller (if available)
   If a Silicon Motion Uninstaller is listed, double-click it and follow the prompts to remove the software.

5. If No Uninstaller Is Present: Delete Manually

6. Drag Silicon Motion InstantView to the Trash

7. Empty the Trash to finalize removal

8. Reboot Your Mac
   Restart your system to ensure all Silicon Motion components are cleared.
