Toshiba Dynadock 4K (PA5217U-1PRP)

Works perfectly! Keep in mind that you'll need to go to the Toshiba website to download the necessary drivers for the device (the site is pretty straightforward to navigate).

Apparently this particular Model is incompatible with USA products. I *think* it may work in Australia, but you cannot get it to work in the US. When I tried to download the drivers from the Toshiba website, it gave me errors and told me it would not work in the USA. Cannot return because I did not open it for more than 30 days. :-( So much for my $180+ investment. Vendor has nothing on his website about this being for another country which really burns me.

Didn't work
