Can anyone confirm if the new M1 Max (or Monterey) can output HiDPI at higher resolutions than the 1st gen M1 13" MacBook pro? Using a 6k Pro Display XDR on the M1 with 3k scaling is brutal. The interface is way too big. An iMac pro with an eGPU was able to accomplish this perfectly. --edit The Display Dummy app resolves this problem perfectly. In the Display Dummy menu, select 16:9 ratio, then go to displays in system preferences and choose 3840x2160. Curious if it will be able to work with dual Pro Display XDRs on M1.

I'm away from my 13" M1 MacBook right now but there was a 3rd party app I used that lets me choose any resolution and scaling on the built in or external displays. I like having a lot of workspace and thankfully have good eyes so my usual setup is 2560x1600 no scaling for the built in and 3840x2160 no scaling for the external portable USB C monitor I carry around with it. There may well be a way to do it from the CLI as well but the app just sits as a tray icon in the menu bar which is great from a "I don't know what I just plugged in but I want to to just be <x>" perspective.

  Ideally 3840x2160 in HiDPI on the Pro Display XDR. I get this with an eGPU puck on an iMac pro with SwitchResX. Unfortunately the original M1 limited SwitchResX from using HiDPI at higher resolutions. It is limited to 3008x1692 at HiDPI (half of 6k). The higher resolutions are available but they aren't HiDPI and text looks noticeably worse. It's a known issue with several display tools like: https://github.com/xzhih/one-key-hidpi/issues/164 https://github.com/xzhih/one-key-hidpi/issues/164

  Can't you just go to System Preferences and click Alt + Scaled? That usually gives you all the resolutions that your monitor supports without having to use the "Larger/Smaller" visual options.

    the issue was the m1 limited the choices to maximum of 3008x1692. I just tested the Dummy Display app and it resolved this perfectly. The app definitely works, even better than the m1 limitation of SwitchResX.

    It gives more, but not all, resolution and scaling options.

  --update 2 Bad news, you lose HDR color support (ouch). Current workarounds involve toggling BetterDummy as needed, or higher resolution on one monitor and native HDR on the other.
