Not sure if the preview picture of tri-screen support is before using the new adjustment but to me it looks like the driver would have 6' wide shoulders!
it's called fisheye distortion, present in the camera used to take the photo. disclaimer, it is present also in motorsport onboard camera, which makes fans' arguing about race episodes hilarious most of the time. for example stroll vs vettel in formula 1.
I know when i take videos of my triples in ETS (full triple support) often the side monitors look way off, but sitting in the "cab" its actually perfect.
