I used to do double/triple monitors but it's easy to slip into the habit of swiveling the neck instead of the whole body, and over time, that could lead to injury. At least it did for me. Neck pain stopped a while after I went single-monitor. Well, it's still there, but definitely got loads better. Personally, I work with netflix/youtube on for background noise so I can't attest to the attention stuff, but if you're feeling a little neck/shoulder pain, try single-monitor and see if it helps.
