If charging is required during use, connect a USB-C PD charger to the adapter's Type-C PD input; the adapter supports pass-through charging so the host device can receive power while other ports remain active. No drivers are required for most modern operating systems.

Recommendations

For optimal performance, connect the adapter to a USB 3.2 Gen 1 (USB-C) port on the host device. When using 4K HDMI output, ensure the host device and display support the required resolution and refresh rate. Use a quality Ethernet cable for stable Gigabit connections and a PD charger that matches your device's power requirements to avoid slow charging.
