It's only a temporary workaround, but we've posted a bit more detail on the Plugable site about how to roll back the nVidia driver to the working version, and stop Windows Update from updating that one driver in the future.
Here's some steps:
nVidia’s new October Win8 driver version for the GeForce GT 525M and related chips cause DisplayLink’s USB graphics driver to stop functioning. Rollback to nVidia driver version 9.18.13.286 (6/21/2012) solves the issue. If you get in this situation, here’s how to do a rollback (on Win 7; but same applies to 8):

And then you have to stop Windows Update from offering the same update again. To do that, hit the Windows key (to bring up search), type “Windows Update”, expand the important updates, and right click on the one from nVidia and select “hide update”.

We also have to wait for DisplayLink's driver updates, but if you're a Plugable customer and have any requests for us (like getting an email notification when issues are resolved; or if you're hitting any unique problems), just email us at
