If your targeting reticle is in the center of the array then it would be between the bezel of the center two monitors....right?
You are right, I was wrong.
I recall seeing that some games will use the top row to display above the line of sight, it does not display anything below. The targeting reticule is in the center of the bottom middle monitor and the top monitors extends your vison upwards.
However it seems that not all games do that, some games will just have it in the middle and it will be covered by the bezel. This is a really big problem. So it might be a better idea to just not risk it.
