The following guide helps to identify any problems that may prevent the M|Connect dock from
functioning properly. Please note that all connections on M|Connect are tested twice before shipped to

Troubleshooting Guide will help to uncover and fix the specific issue. Start with your operating system. This
guide will help you to resolve any issues with Windows (below) or Mac OS X (Apple) operating systems.
The M|Connect runs on DisplayLink technology. DisplayLink is the world’s leading innovator and
