With my triple monitor setup, HMD equipped aircraft are awkward to use the HMD as it only utilizes the center monitor. I have seen a few sim builders not using HMD in jets for this reason if they use multi projector setups etc. TheWarthogProject is famous for not using HMD on his simulator when using it without VR. Iceman's post Here identifies the issue well.

I would like to see a way we could tune the movement of the HMD or at least have it slew over to another monitor.
The setup for reference that I use see the linked post for Iceman555's setup details. I noticed the issue after adding a head tracker also was seen when I used a joystick on the throttle to look around.
A few more threads talking about this.
