FAQ
Compatibility
Q. Does this device require software or driver installation?
No. The UD-CUBE is a driverless solution. It relies on native USB-C video support from the host system through DisplayPort Alternate Mode or Thunderbolt 3/4. No additional drivers or software are required.
Q. How can I tell if this device is compatible with my system?
To use the UD-CUBE, your computer must have a USB-C port that supports video output via DisplayPort Alt Mode or Thunderbolt. Unfortunately, not all USB-C ports support video. To check compatibility:
- Consult your device manufacturer’s specifications or support resources.
- Look for references to DisplayPort Alt Mode, Thunderbolt 3, or Thunderbolt 4.
- You may also reach out to Plugable support at support@plugable.com for help identifying compatibility.
Q. What operating systems is the UD-CUBE compatible with?
The UD-CUBE is compatible with systems running:
- Windows
- macOS
- ChromeOS
Q. Can this device be used with a USB-A port using an adapter?
No. USB-A ports do not support video output and cannot transmit DisplayPort Alt Mode or Thunderbolt signals. The UD-CUBE requires a USB-C port with native video support and is not compatible with USB-A adapters.
Displays
Q. Does this allow extending the desktop, or only mirroring?
Yes, the UD-CUBE supports both extended and mirrored display modes. You can configure your preference in your operating system’s display settings.

The HDMI port on the UD-CUBE supports up to 3840 × 2160 (4K) at 30Hz, depending on the capabilities of the host device and display.

Yes. The dock requires the included power adapter to operate. While it connects to your system via USB-C, it cannot function or provide power to attached peripherals without external power.
