"As anyone done this?
At a certain HiRez setting AH did stretch the display onto (2) monitors.
Although having the center of the cockpit between two monitors is not what you want. With three monitors this would be a idea set-up!!"
I am running AH with two monitors (@ 2560x1024).
The seam in the middle is somewhat annoying - but with the trackIR, it's not that bad.
The main problem with this - and it would be much worse with three monitors - is that AH basically has a square box that defines the view. With a widescreen resolution, you get a much wider field of view, at the expense of the top and bottom of that view box.
The net result is that the cockpit looks like it is very zoomed in - and I had to set the head position all the way back.
The other problem is that occasionally, the clipboard ends up in an area of the view box that the monitors do not show. In that case, you have to manually edit the cfg files to get it to show up.
HTH,
