I have a UD-3900 Rev B2 using USB-C to HP Pavilion I7 laptop. I am having issue where the HDMI monitor does not have signal. I have disconnected, reconnected and rebooted. IT happened once or twice before but mysteriously resolved. I swapped it to second USB 3.0 and it is working for now. I do have USB-C but not way to connect device cable to it. I run One HDMI attached tl local and second to docking station. Could my USB 3.0 port be bad? Everything else works from dock station, or could it be the cable?
Thank you for posting! I am sorry things are not working as expected while using your UD-3900 docking station, I would be happy to help.
