Video flicker and hdmi cable does not seem to work

I am using a Lenovo T530 laptop with the dual monitor usb 3.0 docking station. I have a Benq GW2760S monitor.
Using the vga cord with the adapter that came with the station I getting a flickering on the monitor. I tried with a hdmi cable and it did not work at all, ie did not see the connect. Monitor showed the no source message.

Hi Jerry,

Thanks for posting. I’m sorry your new dock isn’t working properly. I’d be happy to help!

Given that you mention you received no output at all via the HDMI port on the dock, the first thing is to ensure that the latest DisplayLink driver we recommend is working properly. You don’t mention which version of Windows you are using, but in general the steps are as follows:

  1. Disconnect the dock from the system and please remove the power cable from the dock so it turns off completely. Please keep it disconnected until the last step.
  2. Uninstall the DisplayLink Core software from the Control Panel -> Programs and Features. Don’t worry if this fails, just move onto the next step
  3. Download, extract 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 install the latest DisplayLink software for your operating system from here –>
  6. Reattach the power cable to the dock first. Once the dock is powered on, reconnect it to your system when prompted by the installer which will trigger the final portion of the installation

Please let us know if that helps get the HDMI output to the monitor working properly when you have a time and we’ll go from there.

Thank you,

Hi Jerry,

Thanks for getting back with the update. The next step is to have you keep everything connected (dock and monitor) and run our diagnostic utility PlugDebug –> and send the file it creates to with ‘Ticket 120170’ in the subject line and your Amazon Order ID number in the body so we can match everything up and examine some log files to help determine the next steps.

Just send us the PlugDebug file and the Order ID directly when you have a moment and we’ll go from there.

Thank you,


Thanks for the follow up.
Just ran the debug and sent the file along with the amazon order iD as requested.
