All of a sudden, I’m having troubles connecting my monitors to my plugable USB-C docking station.
I have a HP Spectre Notebook (Win10) and used to connect 2 external moniors (also HP) via HDMI to the docking station (UD-ULTCDL) to have 3 displays in total without any problems.
Everything worked just fine until this morning. Suddenly, the first monitor wasn’t able to connect when I plugged in my laptop. I tried unplugging the HDMI and replugging it but that didn’t solve the problem. I tried unplugging it again, and the other one, which ended with me not having none external monitor working at all. I then tried unplugging everything from the docking station and replugging it: power cable first > then USB-C host cable > then HDMI cables but it didn’t work.
I also tried reinstalling the DisplayLink drivers. One monitor was back - but only briefly, unfortunately. When I touched the HDMI cables of the other monitor to make sure there was no loose contact, the one that had just restarted working, broke down again.
It seems as if the monitor on the HDMI 4k port randomly and briefly displays the screen (but then stops again) whilst the other one on the HDMI 2k port does nothing alltogether.
The monitors don’t seem to be broken as they display a “input signal not found” message when I plug in the docking station. Also, they work perfectly when plugged into the laptop directly.
Same goes for the docking station which is charging the laptop correctly when plugged in.
Do you have any idea how I can get them working again?
Thanks a lot in advance!
