Mac Mini M1 Multiple Display Issue (2 Monitors)
Everything was working before but now it seems like the mac mini is only allowing 1 display.
System Setup:
OS: Sequoia 15.2
Monitors: MSI 27" and Arzopa (Portable)
Cables Used:
- Type C to DP on MSI (Main Monitor)
- HDMI to Mini HDMI on Arzopa
Hagibis Docking Station
Display Settings:
Mirror
- I usually use this settings because Mac still detects the second monitor even if its turned off
- I only turn on the Arzopa if what I’m doing requires additional display
Issue:
When I turn on the Arzopa I only get a blank screen and its not detected when I check the display settings.
Troubleshooting:
I confirmed that it’s not a display issue (Arzopa) but using my Windows PC which I also use on both monitors.
Windows PC Setup:
Cable Used:
- HDMI to HDMI on MSI
- DP to Type C on Arzopa
I tried to use Type C to Type C to connect the M1 and the MSI monitor while using the same HDMI to Mini HDMI on Arzopa. The display on the Arzopa worked again. I tried restarting the system and it was still good. I also tried turning off the MSI and just use the Arzopa as the main display it still good. However, I think the following day or a couple of days after the issue reoccured.
So what I did was to switch Type C port to connect the cable still the same. And since then even the Type C to DP on MSI is not working anymore only the Type C to Type C.
I used another Type C to DP cable which I used before the current cable it still the same.
I was able to confirm that the old Type C to DP is working when I connected my work laptop to the MSI using it.
Also display is good when I use the Type C to Type C to connect to the MSI while I disconnected the HDMI cable on the Arzopa
I got a new HDMI to Mini HDMI today and tried this setup
Cable Used:
- Type C to Type on MSI
- HDMI to Mini HDMI on Arzopa (New)
But still the same
The new HDMI to Mini HDMI is working fine when I connect my work laptop to the Arzopa.
Current Setup:
Cables Used:
- Type C to Type C on MSI
- Unplugged cable on Arzopa
So based so far on the things that I did. Could this be a glitch with the current OS?
Or do anyone can help me resolve for this.
