Its really simple technology... 1. Brighter projectors. 2. The common technique called projector stacking. You'll see it in large outdoor events and more sophisticated projected mapped productions such as in theaters and fashion shows. These stacks (which may not only be vertical in nature) automatically can adjust the projection for the offset of each projector so that everything lines up at the destination.
