I have an Alienware AW2721D and my M series Macs have no problem driving it at 240hz. macOS picks up that it’s a GSync display and supports VRR on it too.

I could never get my two ASUS displays work at anything but 60Hz

    My other setup has an ASUS PA278CGV as a secondary monitor and the MBP hooked up to it drives it at 144hz no problem.

    Make sure your dock, dongle, and/or cables aren’t bottlenecks.

      I've switched docks, dongles, cables, to no avail.

      Support also varies a lot between M chips, and Thunderbolt often doesn't support high refresh rates https://support.apple.com/en-us/101571

      I can't remember now the actual setup I had, sadly
