4. Operating Instructions
Once connected, the adapter functions as an extension of your host device's capabilities. Most operating systems provide native support, meaning drivers are often not required for basic functionality. However, for optimal performance, especially with the Gigabit Ethernet port, it is recommended to check the StarTech.com support website for the latest drivers specific to your operating system.
Display Output:
The adapter supports either HDMI or VGA output, but not simultaneously. Your operating system should automatically detect the connected display. You can configure display settings (e.g., extended desktop, duplicate display) through your computer's display preferences.
USB 3.0 Port:
The USB 3.0 port provides 5Gbps data transfer speeds for connecting peripherals. It is backward compatible with USB 2.0 devices.
Gigabit Ethernet:
The Gigabit Ethernet port provides a stable and fast wired network connection. Ensure the Ethernet cable is securely connected to both the adapter and your network device.

5. Maintenance
To ensure the longevity and optimal performance of your StarTech.com USB-C Multiport Adapter, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the adapter. Avoid using harsh chemicals or abrasive cleaners.
- Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Handle the adapter with care. Avoid dropping it or subjecting it to strong impacts. Do not pull on the integrated cable forcefully.
6. Troubleshooting
If you encounter issues with your USB-C Multiport Adapter, refer to the following common troubleshooting steps:
- No Display Output:
- Ensure your host laptop's USB-C port supports video (DisplayPort Alternate Mode). Not all USB-C ports have this capability.
- Verify that the video cable (HDMI or VGA) is securely connected to both the adapter and the display.
- Try connecting the display directly to your laptop (if possible) to rule out display or cable issues.
- Restart your host device.
- No Network Connection (Gigabit Ethernet):
- Ensure the Ethernet cable is securely connected to both the adapter and your network device.
- Check your host device's network settings to ensure the Ethernet adapter is recognized and enabled.
- Visit the StarTech.com support website to download and install the latest Ethernet drivers for your operating system, if necessary.
- USB Peripherals Not Recognized:
- Ensure the USB peripheral is properly connected to the adapter's USB 3.0 port.
- Try connecting the USB peripheral directly to your host device (if possible) to confirm it is functional.
- If connecting a high-power USB device, ensure your host device can provide sufficient power through its USB-C port. The DKT30CHV is bus-powered and does not support USB Power Delivery to charge other devices.
- Intermittent Connections or Performance Issues:
- Ensure all cables are firmly seated and not loose.
- Avoid excessive bending or strain on the integrated USB-C cable.
- Reduce the number of simultaneously active high-bandwidth devices if experiencing slowdowns, as all ports share the USB 3.0 bandwidth.
