I am planning on ordering an M2 Mini soon. On the Apple website one spec reads: "HDMI display video output: Support for one display with up to 4K resolution at 60Hz". At this time I plan on using the HDMI port for a 27" monitor. If I get a monitor that has various rates does it default to 60Hz? Should I just look for a monitor that only has 60Hz? I have always had iMacs so I never had to concern myself with all the various specs in a monitor.
