Display Link Suddenly Stopped Working

[ujwalm]

Thanks for your reply. Whenever I connect CADYCE the Generic Billboard Device is shown. When I remove it it is not shown in the USB. Please see this video..

Also, both of these used to work earlier using DisplayLink.

This confirms CADYCE adapter is not a DisplayLink device. I believe it is a USB Alt-mode adapter. For further help wit this particular device I recommend contacting support of the product manufacturer.

Do you have any other device?

hi,

monday everything worked fine but today only 2 of my 3 additional screens are working.

set-up
macbook air m4
Tahoe 26.3.1
3 external screens
3 screens are connected to with hdmi
displaylink hardware

the software is showing the 2 screens as active but no longer showing the 3rd screen at all in the software visual which would mean it is not seeing the screen at all.
