Genuinely curious but why would people put 2 displays side by side so that your neck would always be bent to a side?

That totally looks like a tiring solution. I never do that but put the main display (which is an external monitor of my laptop) parallel to the keyboard and my laptop to the side so I will be facing forward naturally.

In France, my OSHA auditor actually requests that if there are two screens, they be put with the centerline in the middle (I bet it’s a clerical error, but it’s funny to see clerical errors that recommends the opposite of the healthy solution).

I had side-by-sides at an old job. I found I switched back and forth often enough that I wasn't really hurting my neck.

I put multiple displays in portrait mode maybe 10 years ago and have never looked back.
