Erognomic set-up for four monitors

[erwilm45@xxxxxxxxx]

Hello all,

Thanks for your past reponses to my posts.  I was wondering for those
that use four monitors, how they liked stacked monitors vs 4
side-by-side.  Which solution is more ergonomically correct?  I'm
wondering if craning my head upward all day will ultimately cause
problems not only from a phsical perspective, but also ease of use
perspective.

Again, thanks in advance for your replies.
