If your HYC display isn't working on Ubuntu or Arch:

The HYC USB Display Driver is powerful but temperamental. The manufacturer provides the driver, but their support documentation is often translated poorly, and the driver dates are usually 2-3 years old (even on brand new boards).

Before buying a random "USB 3.0 HDMI controller" from China, ask the seller for the VID/PID (Vendor ID/Product ID). If it starts with VID_17E9 (DisplayLink), you're safe. If it starts with VID_048D (HYC), be prepared to spend an afternoon troubleshooting driver conflicts. Have you struggled with a HY-780 or HY-UD series board? Let me know your VID/PID in the comments, and I’ll help you find the right driver package.
