Just got the new macbook pro 14" with the M1 Pro chip, which is supposed to support dual monitors. Hooked it up to my Caldigit and it worked initially (once) but now I only have one monitor working. Any setup steps I can take on the Mac itself or is it all autosensing?
Hello fryguy12,
Based on the following resource, Connect a display to your Mac, when connecting two external displays, you should be using the Thunderbolt 4 (USB-C) and HDMI ports. Have you tried this without the CalDigit? If not, we'd recommend giving that a try.
If the issue continues, the following resource should help: If your external display isn't detected or appears blurry when connected to your Mac.
We hope this helps.
Thanks for using Apple Support Communities. Have a good one!

Thanks for the help. It turned out that the monitors' sensing was flaky. Toggling the monitors' power solved the issue.
