Hello haphazard44,
Please make sure the FlipGo Pro is receiving sufficient power.
You can try unplugging and replugging the USB-C cable or restarting your Mac with the FlipGo connected.
Additionally, please confirm that the FlipGo Pro has the latest firmware installed.
If the issue persists, consider running the
End-User Cleaner Tool to reinstall DisplayLink app.
If the bottom screen still won’t light up after these steps, we recommend contacting JSAUX support to verify DuoViews compatibility and any device-specific requirements.
