I am reposting this here. Trying to get it out as much as possible.
This is
what I received from ASUS Support.
"I just got a reply , and for the
TAICHI21, it does not support any dock station, it means there is a
compatibility issue between the TAICHi21 and the HZ-1 dock, so it is not only a
driver issue. You had better not connect the dock to the TAICHI21 for usage. And
our engineer won't develop any new driver for this issue. Sorry if any
inconvenience this case.
Best Regards,

as a note the "HZ-1" uses the DisplayLink driver just like
all the docks out there.
