M1 laptops can only support one external display at 6k and 60Hz. The other video goes to the laptop's own display. Even if you use the laptop closed in clamshell mode you can't connect or daisy chain to more than one external display.

The mini can support two external displays. One via thunderbolt at that same 6k and 60Hz and the other a 4k at 60Hz through the HDMI port.

Note that the restriction on external monitors can be worked around by using a DisplayLink compatible dongle/dock, since it uses a custom driver (I assume it does something in software that would otherwise be limited in hardware).

I use the Dell D6000 and I run three (1080p) external monitors in addition to the built in monitor.

I've been trying to find a DisplayLink dock that can output video via USB-C or Thunderbolt. Everybody's shared solutions always involve HDMI connections, never USB-C.

I have two Thunderbolt/USB-C monitors that I was hoping to daisy chain with one wire from my Mac. Alas it's not possible.

My hope is power into a dock. Thunderbolt from dock to laptop to power laptop. Thunderbolt/USB-C from dock into first monitor. Second Thunderbolt/USB-C from dock using the DisplayLink tech to second monitor.

You won’t find a Displaylink adapter that supports Thunderbolt monitors. It just won’t work from a technical aspect.

Three 1080p displays add up to 3/4 the bandwidth of one 4k display, at the same framerate.
