FAQs

Does this adapter require separate power?

No, the adapter is USB-powered. It can run solely on bus power from your computer. However, it also supports 100W USB Power Delivery (PD) pass-through, allowing you to charge your laptop simultaneously if you connect your laptop's USB-C power adapter to the adapter.

Can I connect two 4K monitors at 60Hz each?

Yes, the adapter is DisplayLink certified and supports dual 4K (3840 x 2160) resolution at 60Hz on both connected HDMI displays, provided your computer's USB port and graphics capabilities can support this output.

Do I need to install any software to use this adapter?

Yes, you need to install the DisplayLink drivers for your operating system (Windows, macOS, Ubuntu, or Chrome OS) for the adapter to function correctly and achieve optimal performance.

Can I connect this adapter to a USB-A port?

Yes, the adapter comes with an integrated 1ft cable that has a USB-C connector. It also includes a USB-C to USB-A adapter, allowing you to connect to traditional USB 3.0 (or higher) Type-A ports on your computer.

What operating systems are supported?

The adapter is compatible with Windows (including Windows 11), macOS (10.11 and later), Ubuntu (18.04 LTS/20.04 LTS), and Chrome OS.

What is PD 3.0 with Fast Role Swap?

This feature ensures that your data connection is not interrupted when switching power sources. For example, if you disconnect your laptop's USB-C power adapter from the hub, it will seamlessly switch to USB bus power without dropping your display or data connections.

What is the maximum resolution supported?

The adapter supports a maximum resolution of 3840 x 2160 pixels (4K) at 60Hz for each of the two connected HDMI displays.

Troubleshooting

Displays not detected or showing a black screen.

Ensure DisplayLink drivers are installed correctly and are up-to-date. Verify that the HDMI cables are securely connected to both the adapter and the monitors. Try restarting your computer after driver installation and connection. Confirm the monitor input source is set to the correct HDMI port.

Video resolution is lower than expected (e.g., not 4K 60Hz).

Check that both the adapter, the HDMI cables, and the connected monitors support 4K resolution at 60Hz. Ensure the DisplayLink drivers are installed. Verify that the computer's USB port is USB 3.2 Gen 1 or higher, and that the system's graphics capabilities can support the desired output.

Laptop is not charging when connected to the adapter's PD port.

Verify that your laptop's USB-C port supports USB Power Delivery. Ensure you are using a USB-C power adapter that can supply sufficient wattage (up to 100W). Confirm the USB-C power adapter is properly connected to the adapter's USB-C input port.

Adapter disconnects intermittently.

Try a different USB port on your computer. Ensure the USB cable is not damaged and has secure connections. Close unnecessary background applications that might be consuming system resources. Update your computer's chipset and USB drivers.

Poor video performance, stuttering, or lag.

Update DisplayLink drivers. Reduce the resolution or refresh rate if your computer's performance is insufficient. Close any demanding applications running in the background. Ensure the USB port used is USB 3.2 Gen 1 or higher.

  4. Connect Power (Optional): If you wish to charge your laptop, connect your laptop's USB-C power adapter to the adapter's USB-C port. The adapter will then pass power through to your laptop.
  5. Configure Displays: Your operating system should detect the new displays. Configure their resolution, arrangement, and extend/mirror settings through your system's display settings.

Care:

  • Cleaning: Wipe the adapter with a soft, dry cloth. Avoid using liquids or abrasive cleaners.
  • Cable Care: Handle the integrated cable gently. Avoid sharp bends or kinks. Use the strain reliefs to prevent damage to the connectors and ports.
