Do they exist?

If so, does anybody have a link?

Just bought two from eBay and neither works.


I did research last year for the most popular Thunderbolt to HDMI adapter I could find. Like some users my first adapter did not plug in tightly and signal could shutoff on it's own. The Vendor actually reached out to me before I could complain with a customer satisfaction survey. I told them the problem and a new one arrived in a few days and I'm still using it.

  • BTW - you're using Ubuntu? Which DE? Does it create an interface that appears in something like Arandr? – Daniel R Oct 30 '18 at 13:18
  • Ubuntu 16.04 and 18.04 with Unity interface. Xrandr name is DP-1-1 but it may vary by machine. Skylake 6700HQ with 40 gbs PCH Thunderbolt. – WinEunuuchs2Unix Oct 30 '18 at 17:50
  • Thanks. Just wanted to make sure that what I bought indeed wasn't working as expected. No additional interface appeared in xrandr. – Daniel R Oct 31 '18 at 10:52
  • When you buy these adapters the fine print specifies what operating systems and hardware types are supported. – WinEunuuchs2Unix Oct 31 '18 at 10:54

I am using Club 3D CAC-1504 USB-C to HDMI 2.0.

Laptop: Latitude 5580, i5 7440HQ, NVIDIA 940MX with Thunderbolt3 over USB-C.
Monitor: LG 32UD59-B, 32 inch, 4k@60Hz.
OS: Ubuntu 18.04.1

Some laptops have DisplayPort over USB-C(Latitude 5590, i5 8250u, no discrete GPU) and the above adapter works with LG 32UD59-B.

Other laptops have USB-C only for data transfer(no DisplayPort, no Thunderbolt3) and the adapter will not work.
