Screen keeps flickering, internet connection dropping in/out, keyboard freezes

Recently over the past month or so screen freezing but green light staying solid throughout. “2nd monitor is ASUS VS247” and is used as the main monitor with laptop monitor not used (so 2nd screen only).

comes back to normal after a few seconds with everything operational but at its worst it happens every minute or two. Has happened three times whilst adding this post. Laptop standalone is fine and no display/keyboard issues whatsoever.

Have updated displaylink drivers via plugable website this week but made no difference.

Device : Surface book2
2nd screen: ASUS VS247
Windows 10 pro, version 10.0.18363 build 18363

Hi Salim,

Thanks for posting!

The first steps we’ll want to take are to perform a power-cycle of the unit to reset its internal hub chipset. We’ve seen that this can often restore the dock back to a working state when one or more of its functions are not quite working. To do this, please follow these steps:

  1. Disconnect all USB peripherals and the display connected to the dock
  2. Disconnect docking station from host machine, then disconnect the power adapter from power
  3. Leave unplugged for 1 minute for power to dissipate
  4. Connect docking station initially into power only
  5. Connect docking station to host machine, then connect USB peripherals and the display, then test for functionality

If this helps, great! If not, I’d like to request some logs from your computer to best investigate further. Please keep the Plugable dock connected (with everything still attached), then navigate to our PlugDebug tool and follow the instructions there.

Please send the ZIP file created to us directly at, and include “Ticket #324016” in the subject line to help match up the details to this case.

Thanks for giving us a chance to help!
