Why can't you? I am typing this from an M1-MPB with two monitors. I just have 1 through thunderbolt and 1 through the hdmi.

You clearly have an M1 Pro or M1 Max MPB since you have an HDMI port. The base M1 models support the built-in display and 1 external display except the M1 Mini that's allowed 1 monitor over HDMI and 1 external display over TB. The Pro, Max and Ultra M1 models allow more displays.

I have a "MacBook Pro (13-inch, M1, 2020)" and I clearly can't have 2 external monitors. I tried everything.

  That model has built-in support for a single external display in addition to the built-in display. If you want a second external display, you have to use third-party DisplayLink technology, which may be good enough depending upon your use case, but is inferior to built-in support.

    Parent poster could also connect additional displays: - via Sidecar on an iPad - via Airplay on a display of their choosing Just mentioning workarounds, not excusing things.

  I had a m1 mbp and have used three external monitors from day one. Used a startech 3x4k hub for that. It uses display link - which is sw-based rendering. Worked like a charm for dev work. You likely couldnt tell that from directly connected monitors unless you wanted to push rapidly changing content (like scrolling through logs at 60 screen-heights per second) - then compression would be indeed visible. For work, videos and occasional session of gzdoom it was a-ok.

    Are you able to push 120hz on both external monitors? I’m guessing not. Looked at 2 startech DP dongles and all permutations seem to tap out at 60hz. Really hoping I’m wrong, would love a 120hz solution if possible.

      No, 60Hz max with the startech.

        Damn. That's a bummer. I want a 3rd screen but I am pretty spoiled by 120hz now. It's so easy on the eyes.
