Some displays stopped working

[KendalSummers]

I'm not super sophisticated with tech stuff. I add 3 monitors to my Mac with Display link. Sometimes, when I reboot, I have to open Display Link to get all of the monitors to show up.

This week, despite repeated reboots, quitting the app, unplugging everything etc. I can only get 1 additional monitor to show up. All of the others remain dark. DisplayLink is installed and working, it's just showing only 1 of 3 monitors.

Thanks,
