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,

I had two HDMI monitors running and now only one works....bummer.

Did this happen just in the last couple of weeks? I see other posts here that make me think it may have been a larger issue. Maybe Mac did an update that's causing this problem for all of us?

I had same problem - suddenly two external monitors stopped working on MacBook. Solution is so simple it is embarrassing, at least for my situation. I needed to click radio buttons to turn on each monitor. No idea how they because 'unclicked'.

previous it was working with my usb C Dell WD19 docking, via 2 DP display cables en monitors. I had 3 differents screens... Now it works but the 2 external monitor screens are the same content ( duplicated) , the mac has another screen. It says in displaymanager that there are no dp enabled screens but it is connected with dp cables... i can't see de radio switches in displaylink manager because the monitors doesn't show.
In display settings it just show 1 screen, if i pull out 1 DP cable it shows the other screen.
Something wrong with the OS en screen sharing?
greetings, Sjalski

For your reference, DisplayLink technology is combination of hardware and software.

According to the information here --> https://www.dell.com/support/home/en...-dock/overview The Dell WD19 docking station does NOT use DisplayLink technology.

As a result, DisplayLink will not be able to assist you.
