For some time I tried to adjust my screen with the "Multiview" option checked and I had trouble adjusting to all this, I do not quite understand the Field Of View. I browsed several forums looking for information required to determine the angle between the 3 monitors but without success! Some guys placed a few monitors at 40 °, 45 °, 50 °, 90 °! but without explanation Today, I tried to understand the perspective of the "multiview" and I did a sketch of my reasoning and my understanding. here is : Naturally, it is the F.O.V. horizontal, here is for the vertical: h = height of the monitor d = distance between you and the monitor fov_vert. = (arcTan((h * 0.5)/d))*2 if you have any suggestions or questions, do not hesitate! I have not tried it yet because I will not be home for a few days, but very confident about it working.
