Hi Support, I am using a brand new UD-ULTC4K dock and I am unable to get the HDMI monitor to connect to my desktop computer. The two display port monitors are connected and work well, but I am unable to get my computer to recognize the monitor connected via HDMI. I’m attaching a log below.
Thanks for reaching out to Plugable support! I’d be happy to help with that.
Looking at the specifications for this computer, it looks like the USB-C port in the front is data only and will not support the Display 1 connection for this docking station.
It is not typical for desktop computers to support extending displays through a USB-C port as they tend to have more room for internal expansion that allows for adding additional graphics processing units, which is a better way to extending multiple displays when possible.
With this type of computer connected to this particular docking station, we would expect everything to function except for the Display 1 connection and the ability to power the computer through the USB-C connection.
If you would like recommendations on other products that would work to extend additional displays using technology such as Silicon Motion or DisplayLink, please let us know.
