Q: I have plugged in my monitors but I don't have any display on any of my monitors, what should I do?
A: Although Windows and ChromeOS have DisplayLink Drivers natively installed in the Operating system they may need updating. When you plug in a DisplayLink product and get no display then always update to the Latest Drivers Here first. In 99% of cases, once these are updated your displays will work. If you are a MacOS user then refer to the section of the User Manual that explains how to install the DisplayLink Manager. The DisplayLink Manager has to be running on MacOS for DisplayLink to work. If these steps do not solve your problem then please contact Comsol support on Live Chat or here and one of our team will give you further assistance
