We have a lab of Mac Mini M1 machines and often times they will not recognize the monitor that is connected with USB-C cable. We just get no signal. We try unplugging and plugging, turning off the monitor and ultimately restarting the mac mini. Very frustrating to have this when students are trying to get work done. Any suggestions?
Hi tgolden79,
Based on the issue you're describing here are some troubleshooting steps you can try from the If your external display isn't detected or appears blurry when connected to your Mac resource:
"If your display is blank or not detected
Try these steps if you don't see an image on your display.
Check your cable or adapter
Disconnect the cable from your external display from your Mac, then reconnect it. If the cable from your external display doesn't connect to the ports on your Mac, you can use a USB-C or Thunderbolt adapter. If you're using a USB-C or Thunderbolt adapter to connect a display, the adapter must be compliant with DisplayPort Alt Mode or Thunderbolt / USB 4.
Check how many displays you can connect
If you're connecting multiple displays to your Mac, use the Tech Specs page to find out how many external displays your Mac supports.
We hope this helps.
Take care.
