Why do movies love showing giant surveillance screens? Real-life advantage or just a power move?

I've always been curious about those scenes where FBI agents, hackers, or masterminds stand in front of a wall of screens, each showing different live feeds. It looks super cool and gives a sense of "ultimate control"—but does it actually serve a real-world purpose? For example, this scene (see image) from The Blacklist s3e15.
