Nice work, now you need to work out how to activate multiple screens.
As it is now, the LCD is just showing a duplicate of the laptop screen, but you can set it up so the two are independant and show a different program or whatever you want, it is very handy. For example, you can have one screen with the browser open with a processing tutorial, and the other with Photoshop open, saves having to hide/show one or the other as you can just look at the second screen.
I have three screens at work(built-in, VGA and HDMI) and sometimes wish I had another!

Usually the laptop screen has email client or browser on it, another has PDF drawing with clients comments/markups, and last (biggest) screen has Autocad with latest drawing revision. Massive timesaver.
