I have been using a UD3900 docking station supplied by my employer to work from home. It has been working well at the office, and then here at home with my laptop for the past 4 months. I was also unplugging it from my laptop and into my personal desktop when not working. It has been working fine with my double monitors.
Friday, both monitors started showing “no input” when plugged into my laptop. I have verified all connections are good and tight. Then, when I plugged into my desktop, again, monitors displayed no input.
I went to the office and got a replacement dock, same model, but to no avail. I then upgraded to a UD3900H. The same thing happened. Both screens still displayed “no input”. However, when I moved the connection to another USB port on my desktop, I was able to get the screens to display. However, no matter what port I use on my laptop, I have not been able to get it to function. Still showing no input on the screens.
I tested the monitors by plugging them directly into the laptop and they work fine, as well as working on an alternate USB port on my desktop.
I have been working with my original docks, both computers, and same ports for 4 months working at home with no problems.This issue just started this past Friday and I have not been able to rectify. I should note that the docks seem to work fine with the keyboard and mouse on both computers.
I have powered down all units a number of times and restarted to no avail.
Can you advise?
