The 4K ultra fine specifically says in the docs about daisy chaining two together.I was told that one TB3 port will not support two monitors
I agree it should There’s one way to find out and just by another Ultra Fine when it becomes available. I can always hook it up to another TB port. My information came from Apple Support via Messages and sometimes I’m not sure I’m getting correct replies as it is a automated system.The 4K ultra fine specifically says in the docs about daisy chaining two together.
tb3 can definitely run two 4K displays from one port (I do it with a 2018 mini and a dual dp adapter) but that’s only gonna work if your gpu provides enough DisplayPort streams. I don’t see why a 2020 intel mbp13 wouldn’t run two 4K ultrafines daisy chained (the m1 Macs have limits on DisplayPort outputs)
