As many have learned over the past few years, there is a good bit more to building an effective digital signage network, control room monitoring system, or a knockout videowall than just connecting a few wires and bolts and making things flash. Making it produce results requires a thoughtful plan, the right content, and careful timing. Still, the foundation is solid hardware with the right control features, mounting options, and screen type to provide a reliable platform for the message. The LCD displays we survey here offer the right mix of video connections, screen brightness, and contrast parameters along with mounting and compatibility features needed for effective display and monitoring in the demanding, high-uptime commercial environment.
