Wouldn't it be better to use head tracking to get the position of the head relative to the monitor, so the monitor behaves like a window? Like in Johnny Lee's classic Wii demo [1].
The way it currently works (rotating the view upon head rotation) doesn't really make sense because a monitor is not a head mounted display.

And yet, sim players are using it. Players want to use small headmovements to simulate large head movements ingame. It seems to work.
My kid is using a webcam based head tracker with a combat flight sim of some sort. You don't want to move your head too far since you are looking at the monitor right? It works kind of like mouse acceleration where if you move your head quickly, it changes perspective further.
If it behaved like a window you wouldn't be able to look beside or behind yourself in game, this type of setup is used a lot for sim games.
