Wow, thanks for pointing that out. Since TB / USB-C use the same transmission format which is DP specifications, I found this statement from BENQ: There are two types of ports that allow you to daisy chain monitors: DisplayPort and Thunderbolt. Ensure that your PC features an output port of either type and that the monitors feature both input and output ports of the same type. Please note that MacBook®computer only supports daisy chaining via Thunderbolt.
Basically stated, TB to DP won't daisy chain. However if you own monitors that can daisy chain to USB-C connections, will that be supported by MacOS, I.e. the monitors support USB-C and not TB4. I mean there are what, 2 TB4 monitors available... Apple's and LG?
