[SOLVED] USB-C Hub No HDMI Output

Hi - I have a new UtechSmart USB-C hub, model: UCN3273, where all the ports work as expected except HDMI has no output.  I've done some searching, but not finding much on the USB-C hub HDMI issue in general. So, it must be working for most hubs.

Here's some information:

Wondering, am I missing some USB-C driver? Doesn't seem like it as the USB and Ethernet ports all work as expected.
Thoughts??
Thanks

Re: [SOLVED] USB-C Hub No HDMI Output

According to this Asus site, my USB-C connector is a data only connector without charging or display ability.

Re: [SOLVED] USB-C Hub No HDMI Output

Certainly has display ability lol smile why would it have HDMI if it didn't? I have the very same hub, HDMI worked till 3 or 4 days ago. Misteriously, it stopped working. Tried with another monitor, cables, etc. Even asked the vendor for another hub, as i thought the hub got damaged, even with the new hub,  doesn't work as well! I am so lost as why it stopped working.

Murphy descended to Earth, no way to stop him now.

It's the OP's laptop that didn't have ability to transmit a display signal over USB-C, not the hub...

Closing this old topic.

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan
