My laptop screen goes blank when I plug in my new Plugable UD-3900. When I first started, both the laptop and monitor stayed on. Then I hit to change the projection settings. Now the laptop screen stays blank no matter what setting I choose.
Hi Steven, thanks for posting! Sorry to hear that your laptop screen is blank after connecting our dock and I will be happy to help!
Thanks for the description of the behavior you are seeing, definitely strange in that your laptop screen is no longer displaying. We will first want to see if we can get the internal screen to display again by disconnecting our dock and rebooting your system ( likely by holding down the power button to preform a hard shut down ). Once your system reboots, does your laptop screen display? If not, we will want to use the Windows Key + P keyboard combination to see if we can set your system to PC Screen Only in order to set the internal laptop display as active (example screenshot attached).
Does using the Windows Key + P keyboard combination help to get your laptop screen active again? Please let us know whenever you have a moment and we will go from there.
Thank you,
David W.
