How to fix your DisplayLink product from repeatedly disconnecting and reconnecting, or freezing

Your USB video adapter, USB docking station or USB monitor constantly disconnects and reconnects, or freezes.

When this happens:
  • You repeatedly hear the device disconnect and reconnect chime
  • Your attached monitor will repeatedly flash off and on again
  • Or your DisplayLink display freezes or locks up, while directly connected screens, eg the built in laptop screen, continue to work.
This can be caused by loose video cables or USB instability. Firstly check that the video cable is fully plugged into the dock and the monitor. If it is loose, the monitor will be detected and then lost by the dock, causing display reconfiguration. If this does not solve the issue, follow the steps below:

Check if you have the latest DisplayLink software installed


You can locate the latest version on our Driver Downloads

Check if you have the latest USB 3.0 host controller driver installed on your PC

  • If you have Windows 7 installed see this article to obtain the latest USB 3.0 host controller driver
  • If you have Windows 8 or above installed then the driver is supplied and controlled by Microsoft

Check if you have the latest USB hub firmware programmed on your product

Check with your product manufacturer to see if there is a USB hub firmware update available

Check if you have the latest BIOS version installed on your PC


Visit your PC manufacturer's website to see if there is a BIOS update available for your computer. 
Also check if USB 3.0 mode (if present) is enabled in your BIOS

Check if the same behaviour is seen when connected to a USB 2.0 port on your PC (or if none is available with a USB 2.0 cable)


Some USB 3.0 enabled PCs can exhibit issues on USB 3.0 ports but not on USB 2.0 ports

Check if the same behaviour is observed with a different USB cable or USB port


As with other kinds of cable, USB cable quality can vary. We have also been made aware of rare quality issues with selected USB ports on a laptop series.

Try a USB 'Y' cable (if you are using a USB powered monitor product)


Ensure you connect both ends of the 'Y' cable to USB ports on your PC

Try connecting your product through an external mains powered USB hub


Some USB 3.0 enabled PCs can exhibit issues which can be resolved by connecting your product through an external mains powered USB hub
