Does anyone know how to change the field of view, or is this even possible? I'm looking to set up 3 channels, one straight ahead, one with a right view, and one with a left view. I'm looking for a FOV box (in degrees) of (-40 x 40 x 20 x -25) for the straight channel; (-120 x -40 x 20 x -25) for the left channel; and (40 x 120 x 20 x -25) for the right channel.Each monitor (channel) will be run and fed by a different PC running an instance of FSX. So I'm only looking to set up one of these FOV per one instance of FSX.

You'd want to take a look at the SimConnect Docs for the function SimConnect_CameraSetRelative6DOF.The only thing you'll probably have to really change is fHeadingDeg, although the eyepoint delta, pitch and bank can also be set.
