The effect looks similar to head tracking. Basically the software knows where you are looking (not sure what it does in this case) and adjusts the ingame camera accordingly, so rather than the screen being the limit to the camera, your head is. When you look to the right, you can see things that would otherwise have been hidden by the tv frame.
It's similar to looking out a window, giving the illusion of 3d.
