What I have tried:
I have not found any information on this issue so it may be very new, and help would be greatly appreciated.
I have exact same issue but with new XPS 15 with factory installed Windows 8. Everything appears to be installed properly, DisplayLink icon available, multiple monitors available...when I enable them the laptop screen flashes continuously until I disable. Dell should not sell this Targus dock as if it is compatible, this system will be returned.
