Download and install the Displaylink Driver (InstantView)

1. Download and install the Displaylink Driver

For HDMI 2 and VGA port to function, make sure to install the Displaylink Driver and authorize screen recording permission. After granting permission, remember to restart your Mac. Please click the link below to download the Displaylink Driver.

2. Turn off auto-updates & stick to Displaylink Driver V3.14

We've observed version 3.15 exhibiting freezing issues. For this reason, we advise against automatic updates to this version. Please wait for a new release at the end of August for a safer update. You can deactivate automatic update checks by right-clicking on the InstantView icon and unchecking 'Auto Update'.

To see basic information about your Mac, choose Apple menu > About This Mac > More Info > System Report > Hardware > USB.

In order to verify the proper connection of the dock, ensure the detection of "SMI USB Display".
