The description at http://club-3d.com/index.php/products/reader.en/product/club-3d-usb-31-type-c-to-displayport-12-uhd.html says that the CAC-1507 is active.
Does that mean a passive version is possible? If so, then what would be the differences between an active and passive version of this adapter? What are the benefits of each over the other?
What kind of active conversion is required between the USB-C DisplayPort alternate mode input and the DisplayPort output?
