Have you ever thought of running your simulation system not only with multiple displays but also multiple computers?  Peter Rowney did that with Wideview software connecting 5 computers and 5 displays, giving more than 180 degree wrap-around view.

Builder: Peter Rowney
Location: Lemon Tree Passage, NSW, Australia
ICAO: YWLM, Williamtown RAAF Fighter Base

Project Notes:
My Location is Lemon Tree Passage NSW Australia. I fly at YWLM Williamtown RAAF Fighter Base as a private pilot.

My cockpit consists of 5 computers running 5 flat screen 24” LCD monitors.
I use WidevieW software to network the 5 computers which gives me slightly more than a 180 degree wrap-around view.

I have the Saitek yoke and throttle quadrant, 6 x instrument gauges running your Centurion gauges. Also I have the Saitek Auto-pilot and radio stack plus switch panel. I use CH Pro rudder pedals.

Obviously I run FSX with the Aceleration pack installed. (each computer requires it’s own install of all the software, a huge and daunting job from scratch
I use the ORBX Australia Scenery and mainly fly between Cessnock YCNK, Warnervale YWVA and Aeropelican YPEC. I mainly fly the Carenado C172N at the moment.
