Wow. That is a pretty crazy setup. I would worry about neck problems with the position of the top row. How long have you worked with this setup? Also what make/model/spec is the laptop you run it all from?
It's taken a few years to build up to this. To mitigate neck pain I:
1) Have set my chair so that it rocks as far back as possible with little force.
2) Sit directly across from the gym and try to visit it twice a day for at least two 15 minute HIIT cardio / body weight workout. I do lots of pull-ups, archers, and have been working up to the iron cross.
3) Only use the upper deck monitors for security reviews where I need "eyes on" resulting actions. I don't use them on a daily basis.
