Upgrading from a UD-3900 to UD-3900H for a 3 VGA monitor and laptop setup. Yea or Nay?

I currently have the UD-3900 dock at work and its working great all these years. It connects my 3 monitors to my laptop. I plan on doing the same setup for home but the dock is pretty big and thought that the UD-3900H can do the job. The setup both at work and home is as follows…
3 Dell D2015H monitors (vga ports only), each vga cable is connected to…
1 Plugable vga to DVI adapter, which is then connected to…
1 Plugable UGA-165 USB 2.0 to DVI adapter that then connects to the dock. At work its the UD-3900 and currently at home its just a 7 port hub that is connected to my Samsung laptop.
So, considering the UD-3900H has a DVI port and 2 USB 3.0 ports I believe it would work with my setup, or connect the adapters to the other 4 2.0 usb ports. But I am unsure if it would work.

So I ask yea or nay? Can the UD-3900H work for my situation, or should I just get the bigger size US3900?

Hello David,

Thank you for reaching out to Plugable support.
I want to thank you for that very detailed diagram you put together, It definitely helped me narrow your options down a bit better.
I think switching to the UD-3900H from the UD-3900 would be a great solution to save space. The main thing that you’ll be missing out on is the integrated audio ports on the UD-3900. Other than that functionality will be the same.

So, in summary, with the UD-3900H, you can connect one of your DVI monitors directly to the DVI port on the UD-3900H dock. Then, with 6 USB ports available (two USB 3.0, four USB 2.0), you can connect two additional UGA-165 adapters for the other two monitors, keyboard, mouse, Seagate HDD, and 1TB external HDD. This would use all USB ports on the dock.
