Not recognizing external monotor

Hi, my Plugable 3900 dock stop recognizing the external monitor. It was working fine for last one month but suddenly it stopped recognizing the monitor. Monitor is working fine if I connect it directly with the laptop.

Thanks for getting in touch!

With issues like this, it’s tough to tell what’s going on from just the description. We should grab system logs and see what is happening.

Could you contact me at so that I can help gather logs from your system an investigate? Please mention ticket #172227 for the fastest service.


Since we haven’t heard back to you, I’m assuming that the issue was resolved. If this isn’t the case, feel free to contact me at so I can help!
