I own an 18.4 inch tablet (Samsung Galaxy View).  It would be incredible to be able to use that as my screen.  How come the device is not supported?  Obviously it wouldnt fit on the controller but setting up a dinner stand or table at the flight zone isnt really a difficult task.  

Well that's not a surprise, such a big screen....  Is there an hdmi port on your device? If yes, it can be connected through it

No I don't believe their is an HDMI port.  unfortunately.  Its an android device, the only thing out of the ordinary is the screen size.  its a relatively new tablet
