The display seems to have too much zoom when using a triple display system. eg: Zooming right out only reveals the top row of gauges in the c172.
We need an FOV slider to set the base FOV (before Zoom is applied). Like the widescreen setting in FSX, or some sort of value in the main.mcf that we can tweak . The FOV values in the main.mcf seem to only reflect the current "in game" zoom settings the user has set in each view, so we would need an additional "base" value.
I originally got around this by following the Triple Screen setup instructions on the FS2 Steam Community guide, http://steamcommunity.com/profiles/76561198041786331/myworkshopfiles/?section=guides&appid=434030 but only setting up a single screen (and setting it's FOV), but this now breaks the control hotspot locations on the screen in the Aug 26 beta.
BTW, these Community Guide triple screen instructions work fine if your left/right monitors are at 90deg. It doesn't seem to make sense with any other angle as each display rotates around the roll axis independantly.
