11.12.1. USB 3.0 support

USB 3.0 Host controllers on PCs are relatively new and the drivers may not be mature. Connecting DisplayLink devices

to a USB 3.0 port may show issues that are not present when connecting to USB 2.0.

Please make sure your USB 3.0 host controller drivers are up to date, as this can solve many issues with DisplayLink

connected on USB 3.0. DisplayLink provide a knowledgebase article with links to the latest host controller drivers at:

11.12.2. On Windows 8/7/Vista WDDM (Aero and Basic)

DisplayLink software works closely with the graphics card and there may be interoperability issues with some graphics

cards. If this happens:

1. Try to upgrade to the latest graphics drivers for your primary graphics card.

2. Try to upgrade to latest DisplayLink software.

3. Report the issue via your support channel.

4. If necessary, boot into Safe Mode and use Windows' Backup and Restore Center to recover.
