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?

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

According to the information here --> https://www.dell.com/support/home/en-us/product-support/product/dell-wd19-130w-dock/overview The Dell WD19 docking station does NOT use DisplayLink technology.

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