Having trouble setting FOV and setting triples

Hello:
I have triple screens and the images in the side screens are very wrong. I have put all the measurements in the settings of triples. And I cannot put the FOV that my set up throws, that is HFov of 152. I think the max allowed is 130.
Help please.
My setting:
3 Monitors 27 inches: monitor width 60.9 cms, height 27 cms, viewing distance: 63cms. Angle between center and side screens 50.
Thanks
