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

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
