Hi James,
thanks for quick answer.
I uninstalled the old driver cleaned it with the cleaning tool.
But after installing the new 7.7M3 version there is no Change. Still everything works but no display switch and no system tray icon. Before the Update of Win 8.1 everything worked fine on my vaio laptop.
On my older XP laptop I have now also problems. There I installed the newest 7.6m2 for XP because the display didn't worked also.
There I have now the same problem. Display Tray Icon appears for short time and then the massage "there is a old driver installed which is not compatible with USB 3.0" . I had never before this massage. And the device worked well even with USB 2.0.
Everything else works: Keyboard, Mouse, Network
I also change the Display Link Unit with the newest one. Same problem.
I checkt also the Monitor and Cabel...everything is working if I connect it normaly.
Please help
BRGDs
Joe
