Default Nexus 7 (2012) dlmirror app. Does it work?

So i found this app that allows you to mirror Nexus 7's screen to a external monitor through a DisplayLink adapter. But it seems the thread is dead and there's no one saying they got it working. So my question is, does this app work in its current state? I was planning to buy a DisplayLink adapter, but there's not enough information about this.

And forgive my noobness, since i'm new here, and this is my first post
