Asus T100 and Asus VE248 LCD monitor giving NO SIGNAL error through UD-3900

I’m getting no signal to monitor on new setup with ud 3900. Think all my connections are solid. Clueless what to do next. Thought this was the easy part.

Hi Christian,

Thanks for contacting us. I’m sorry your dock isn’t working properly for you. It sounds from your description that the drivers may not have finished installing properly.

We’ll want to proceed with a clean installation of the drivers, and see if the behavior is any different. We’ll do all of the following with the dock disconnected, until the very last step.

  1. Disconnect the dock from the computer

  2. Uninstall DisplayLink Core software from Control Panel->Programs. Don’t worry if this fails, just move onto the next step

  3. Download and run the DisplayLink cleaner tool, found here:…

  4. Once the Cleaner has been run, reboot (even if not prompted to)

  5. Now download and run the 7.7M0 DisplayLink software, found here:…

  6. Reboot, even if not prompted to

  7. Once you’re back in Windows, reattach the dock which will trigger the final portion of the installation

If that doesn’t resolve the issue, we have developed a utility called PlugDebug which gathers some information about your system. It is available from this link:

At your convenience if you would follow the instructions on that page for your operating system and send the .ZIP file that the application creates to with Ticket 79617 in the subject line?

That will help us determine the next steps to take.
