I found that the most problems are for the eyes, if the monitors take too much of your FOV. I worked in the past with 8 monitors and after a while it really impairs my ability to focus far away. Luckily it seems reversible after several months, especially if you spend a lot of time outside looking far away.

You can place monitors at different distances from your eyes. Screen resolution can be changed to maintain perceived relative size of onscreen objects.

For eye health, have the monitors backing a window (or 20+ feet of empty space), so that you can periodically (at least every 20 minutes) look past the monitors at an "infinite" plane.

It’s not practical in an open office with everything standardised. Sure in an Home Office you can do pretty much what you want if you have enough space.

You can at least position the laptop closer than the monitor, which gives you two focal planes. In an open office, there should be many "distant" objects to use as a temporary third focal plane.

I brought my own clamp-on monitor arms to the open office I work in and installed them myself without asking anyone. You might be able to get away with the same.
