Hi, I have a Mac M1. here are the specs:
Mac mini (M1, 2020)
Chip Apple M1
Memory 8GB
I recently bought the UD-3900Z as I need to expand to 4 screens. I am already using the 2 natively supported screens, and want to use the display link HDMI inputs from the UD-3900Z to expand to 4 HDMI inputs. I have installed the DisplayLink drivers. I am plugging all in with regular HDMI to HDMI cables. I have successfully plugged one of the screens into the UD-3900Z and have signal 100% working. However, when I try plug in the 2nd HDMI, there is nothing displayed. There is a display that show in the Display section in System Preferences and it is labelled “No Monitor Display”. So the Mac is technically picking up the screen but for some reason doesn’t want to display to the monitor. I have tested to see if it’s the HDMI ports by having only one screen plugged in with both ports and they’re both working, just not simultaneously. both HDMI cables are working and both screens have displayed, again, just not simultaneously.
Any help would be much appreciated
