I've been trying triple monitor too and also don't like it. I have a 30" in the center which is perfect. Flanked by 2 portrait Dell 20"s.
I found in flight sims with trackir 3 screens is too much information overload to focus on. My SA actually went down somehow. Also in some sims the wide FOV makes object LODs pop in much closer which is extremely annoying when they stay a tiny pixel for ages.
So I'm usin the sides for Shkval/MFDs only but not main cockpit view. Also using them in Skyrim, basically using them in anything that doesn't have Trackir.
