So I had picked up an HP X3 Elite with the Lapdock a while back. Since it was a USBC dock i figured to give it a go with V and it worked perfectly. All options on the dock connect to the V that include the screen, mouse pad and keyboard, speaker (which at the moment sound so much better than the V speakers) and the optional ports. The lapdock has a battery built in to charge the x3. I am going to test how well it does charging the V if at all this weekend. Hope this helps anyone looking for a good option for a second screen.
Update: Tried to charge from the lapdock and it didn’t so that is the only thing that I have found doesn’t work.
