Good afternoon, I have a roughly 6 month old Lenove Yoga13 w I7. I run dual 24: monitors through a Lenovo/DisplayLink USB 3.0 hub. It worked without issue on 8. This week I upgraded from Windows 8 to 8.1. At first it wouldn't recognize the monitors at all, so downloaded the new driver from Display link site. Finally got the both loading, but EXTREMELY SLOW (about 30 seconds to load a web page, won't play video, if you resize a browser window it freezes for a while) Messed with it for another day, removed and used the Display link cleaner, then installed the new hub drivers off the Lenovo site. Everything flew, for about 2 days, now it is back to being extremely slow again. I removed and reinstalled the drivers again, to no avail.
When the laptop is not connected to the hub, it absolutely flies. I have tried disconnecting one or both monitors from the hub, the mouse, the keyboard, the external drive, the speakers, and the hub still seems to have the same effect.
Any help would be appreciated.
