Thanks for that link. For my next work laptop, I've been waiting to see if (sometime soon) there would be a MBP that supported external refresh rates > 60 Hz. Given that the M2 MBA still has that limitation, I suspect not.

  Main reason I went from the 16" Intel to the M1 Pro, dual displays is a must for me when I'm docked at home.

  I can run my Samsung CRG9 (a 49” UW monitor) with one of my M1 machines (an original 13” Pro w/ M1) at 120hz with no issues, FWIW. I suspect it would probably have issues running 4K @120hz however.

    Thanks, that's an interesting data point. Back when I had my M1 MBP, I never managed to get above 60Hz, and I found some articles suggesting that nobody could. I'm curious why you had more success.

      In my case, I had to get a new DisplayPort cable (not all cables will support 120hz). Things were rocky at the start but I believe Apple also released an update to improve compatibility.

    Regular 4k@120hz is totally doable on M1 Max MBP, can confirm that myself. Hard to answer the question regarding 4k+ ultrawides @120hz though, primarily because i dont think there is a display like that in existence yet (googling didn't net much success there for me). The only ultrawide 4k+ display i found that is above 60hz is the LG 5k ultrawide with thunderbolt 4 support, and it maxes out at 70hz (and M1 Max MBP supports it at that refresh rate just fine, that's my current setup).

      IIRC M1 don't support DisplayPort DSC that is needed to handle 4K+ AND 120HZ+. I wish M2 supports DSC to handle this.
