Hi A.S.,
The support case started by the original poster is still ongoing, so there are no updates to share.
I can see that you have also started your own, new forum thread here → https://support.plugable.com/t/samsung-monitor-stopped-working-with-plugable-dual-monitor-docking-station-ud-3900/18916
Every support case is different, so please do not double-post in earlier, different threads for a new issue.
One of support technicians we will continue to work with you directly via your new forum thread.
Thank you,
Bob
