OP your confused by the 2d flatness of your pic that is throwing u off from the reality of it.
yes its live but if you look careful, the big screen is set forward of the minimap screens so it would block the diaganol view of the minimap screens that your proposing. beyond that the wall behind the players blocks the view of the big screen.
to say it a different way, the minimap screens are set back into the wall into the wall in a way so the players cant see them diaganolly. your theory looks good in 2d but it doesnt work in 3d.
