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
