So hooking a monitor up to a machine that's already got one built in results in the same speed boost?
As bizarre as the core finding is, that makes it seem run of the mill.
It makes complete sense when you realize this is all a function of Thunderbolt 4 and the builtin displays on the M1 MacBooks and iMacs are connected via the HDMI interface and not through either of the Thunderbolt 4 ports. The Mac mini is unique among M1 Macs in even having an external HDMI port. NOTE: All of the M1 Macs can drive an external HDMI or display port display using the appropriate Thunderbolt adapter, but whether an HDMI or Display Port monitor connected via Thunderbolt port and adaptor counts as a Thunderbolt or HDMI, ¿quién sabe? 🤷‍♂️. What I know is, the M1 can only drive ONE Thunderbolt display, but it can drive up to fourteen or maybe more, HDMI/Display Port drives. I will leave testing all the various permutations of displays, ports, and adaptors to OWC. They have the necessary hardware and lab space, I don't have enough of either.

If we knew what it was we were doing, it wouldn't be called research, would it?
