Displaylink wont work after Win8.1 Upgrade

Andreas · 10-19-2013, 08:18 AM

Windows 8.1 update failed on some strange driver error and automatically reinstalled old version 8.

On the second attempt Win8.1 installed OK, but left some drivers (like Network, Nvidia GT750M and Displaylink) without functionality. Additionally to this the Fujitsu PR08 seemed to have crashed and only got working after a power cycle.

Reinstalling drivers fixed all other issues but Display Link still does not show any Picture on its connected Monitor. I followed the diplaylink guideline for installing the new 8.1 enabled driver and also used the cleanup tool. Still no success.

USB ports of the PR08 are working OK and general desktop expansion works on two monitors directly connected to the Notebook.

When expanding my desktop to displaylink Monitor connected to displaylink turns on sync LED but claims "no signal". Monitor Name is detected correctly and Mouse seems to use third desktop thoug.

- displaylink core software listed in windows software list
- Device Manager shows USB Displaylink adapter OK
- Win 8.1 service is available and started automatically
- driver hardware ID is VID_17E9
- displaylink diagnostics tool: all tests passed

Anything else I can do to get working again?

Thanks for your help in advance.
