I’ve been trying to setup my UD-3900 to work on my Thinkpad laptop running Windows 8.1 Enterprise for the past couple of days but to no avail. Displays (HDMI or DVI) report that the cable is connected but that no source is incoming. And Windows does not recognize any additional monitors (never did).
The UD-3900 is plugged on the laptop’s USB SS port (I’ve got two of those, tried them both).
The installation of the DisplayLink drivers goes well until the First Connect step which never completes. I eventually skip this part (Skip button), reboot the machine but still, nothing happens. I made sure the cable was unplugged during install. THe UD-3900’s blue and green LEDs are both on when the unit is plugged in the power and laptop.
In the system tray, I see 2 DisplayLink processes, including a System tray process but it does not show up in the system tray. I have followed instructions from the website using the 74.M3 version of the DisplayLink driver.
Any help or pointers would be greatly appreciated. I would love to get this unit working in a plug and play manner as it is supposed to.
