# My monitors keep going black or flickering. What should I do?

Check your cables, DisplayLink software, USB connection, and monitor setup.

Please try the following:

1. Make sure all cables are securely connected.
2. Disconnect and reconnect the docking station.
3. Try another HDMI or DisplayPort cable.
4. Make sure the latest DisplayLink software is installed.
5. If possible, try another USB port on your computer.

**Important**

Monitor flickering or intermittent display can be caused by a loose cable, outdated DisplayLink software, USB connection issues, or compatibility between the dock and computer.
