I have the most recent UD-3900 software, but my 2nd and 3rd monitor freeze and/or flash regularly. To resolve I can disconnect the 3900 and reconnect and it will be fine for a day or two but then happens again. I have Windows 8.1. My husband has Windows 10 with very similar issue.
Thanks for posting. I’m sorry your docking station isn’t working properly, and I would be happy to help!
Just based on the description you provided and the fact that both yours and your husbands unit are experiencing similar issues, you may have run into a bug we recently identified. I wrote about the issue along with a workaround here -> http://plugable.com/2016/01/19/flashi…
If you follow the steps in my post does that help with the behavior with both units?
Just let us know the results as you have time and we’ll go from there.
