4K Port on the UD-ULTCDL

I am using an Asus UX333FA with dual HP monitors. The 4K output on my docking station does not work - is this a limitation or is there something I can do?

Hello Matt,

Thank you for contacting Plugable support! Sorry to hear about this issue. I’d be more than happy to assist you.

Looking at the specifications for the USB-C port on this system, it appears to be a “data-only” port that doesn’t support the required USB-C VESA DisplayPort Alternate Mode video output functionality to drive the 4K HDMI port on our dock. It also appears to not support charging over USB-C as well. Unfortunately these are system limitations and would apply to other USB-C docks like ours.

Please don’t hesitate to let us know of other questions.

Thanks again for contacting Plugable support and best wishes!
