3. Setup Instructions

Initial Connection:

1. Connect the USB-C end of the adapter to a compatible USB-C port on your laptop or device. Ensure the USB-C port supports video output.
2. Connect your primary monitor to the 4K@30Hz HDMI port on the adapter using an HDMI cable. This port is typically plug-and-play.
3. Connect your secondary monitor to the 1080P@60Hz HDMI port on the adapter using an HDMI cable. This port requires driver installation.

Driver Installation (for 1080P@60Hz HDMI Port):

The 1080P HDMI port requires the "UDisplay" driver for functionality. The adapter acts as a virtual CD-ROM drive containing the installer.
