In the world of digital signage, a video wall processor is a lot like a traffic cop: It
makes sure every piece of content arrives exactly where it should be, at the right time
on the right screen, in the correct resolution. Also called a video controller, a
processor is a device that makes a single image appear and move seamlessly across
multiple screens of a video wall. Without it, a video wall would simply be a bank of
digital screens, each showing something different. Processors form a large, cohesive
image, and then send pieces of it to individual screens for display. Although smaller,
more simplistic video walls may only require a multi-monitor video card, as video
walls continue to grow in size and capability, most are requiring processors.
