I think what Angus meant is that if your screen configuration is, say, 3
monitors each offset 50 degrees with respect to its neighbors, then you
should just use 3 channels each rotated 50 degrees with respect to its
neighbors. You might put the three channels in a share group, have one
channel's heading offset by -50 degrees with respect to the master, and
another's by 50 degrees. The FOV of each channel should be 50 degrees,
or perhaps a little more if you need some overlap. Just be aware that
this is only really correct if the (real) observer is standing right in
the middle (but it will actually look pretty good to anyone). And if
you do your tests on a single monitor, it will not look right at all.
