I am looking for an all in one product that I can use to connect an Android tablet to Ethernet, external monitor and USB keyboard and mouse
Thank you for coming to us with your questions. Please note that we currently do not recommend our docking stations for Android due to the Beta status of the DisplayLink driver (http://www.displaylink.com/downloads/…) and due to the limitations that Android and the device manufactures have. You might not be able to us the docking station to its fullest (http://support.displaylink.com/knowle…).
If you are OK with these facts and still would like to give this a shot, there are additional caveats:
For starters you need to be on Android version 5 or newer. Using the UD-3900 for example -> http://www.plugable.com/products/ud-3900 you can only use one mirrored/cloned display. The docking station does not charge the Tablet and you need an OTG cable to adapt the USB port to fit your tablet. Additionally audio and Ethernet functionality is Android device dependent and we cannot foresee which product will have what kind of functionality (this is up to the device manufacturers).
