I'm trying to connect my 2 24" LED Cinema Displays to my brand new 2021 MacBook Pro with M1 Pro chip. I have the correct Mini DisplayPort to USB-C adapters and one Cinema Display works perfectly. The second Cinema Display is not detected. Both work fine with the 2017 MBP I'm replacing. Any ideas while I continue to research? Thanks!
MacBook Pro 16″, macOS 12.4
I'm seeing this on the support page:
If you're using a Mac with M1 Pro:

Should I use one mini displayport to usb-c adapter and one mini displayport to HDMI? Brainstorming...
Update on my arrangement: changed up a bit and connected a dock. Plugged one Cinema Display into dock using Mini DisplayPort to DisplayPort adapter, then one Cinema Display port directly into MacBook Pro using Mini DisplayPort to usb-c adapter. Both working correctly now!
Hi,
Officially your MacBook Pro supports only one external monitor.
