I have CSV-1460 ,and updating MacOS10.13.4 ,display function doesn’t work(It commented past post).
MacOS10.14 released,and install v5.0Beta driver(http://www.displaylink.com/downloads/file?d=191),
Display function work normally!Of cource,another funcion also work.
Possiblyitmaybedefective(because of beta version).
But if you want to use display function,Iwantyoutotryit.
