After having my Dell laptop repaired and Windows 7 OS restored, my external monitor no longer works through my Plugable docking station
Thanks for posting your question here! The most probable cause of the issue would be that the drivers for the Plugable Docking Station has not been installed. Installing the drivers should fix the issue.
Could you connect the docking station to the system, run the DisplayLink Support tool (instructions here: http://plugable.com/support/displayli… ) and email the resulting .zip to firstname.lastname@example.org as an attachment along with your Amazon Order ID and a link to this thread?
Analyzing the .zip would help confirm/rule out this cause. We can suggest the best steps to resolve this issue once we analyze the .zip.
