Multi-Screen Setups

Each BrightSign hardware device has a single HDMI output. In a basic setup, it can connect directly to a single screen via an HDMI cable. However, with the use of additional hardware, including splitters, extenders, or matrixes, you can connect to as many screens as your cabling infrastructure allows for.

What is Cabling Infrastructure?

As with any building, there are a myriad of cables running within walls and through ceilings. When we talk about cabling infrastructure, we are referring to one or more types of cabling, their distance, their connection points, and their ultimate function.

When dealing with a multi-screen digital signage setup, a video signal needs to be transferred from a source device to every screen intended for the setup. There are several variables that need to be considered and there are also multiple ways in which a setup can be achieved. Generally, all involve cables running between the site of the source device and each screen.

Best Practices for a Multi-Screen Setup

Our recommended approach for a setup involving 3 or more screens with a cable distance of 10ft+ includes the following:

  • CAT5e/6 Ethernet run from the server closet to behind each TV screen.
    • CAT cabling is cost-effective, reliable, long-lasting, maneuverable, and multi-purposeable.
    • Long distances can be covered without fear of signal loss.
    • Any AV or IT technician is familiar with this type of cabling, thus specialized expertise is generally not needed to install.
    • Network cabling has become a standard in new commercial construction projects.
    • One downside is that unshielded CAT cabling can be susceptible to interference from other cables, electrical equipment, and even wireless signals.
  • HDMI over CAT6/5e Ethernet distribution system.
    • Turns the HDMI video signal into a data signal that can be transferred across CAT5e/6 cabling.
    • This involves the use of one transmitter plus a receiver behind each TV screen.
    • Can leverage a building's existing network switch or use its own dedicated switch.
    • Consumer grade options have become very reliable and cost-effective.
    • Installation can be tight for setups with limited clearance behind TV screens.

Recommended Distribution Hardware

At the time of this writing, DSID recommends HDTV Supply's WolfPack HDMI to CAT5/6 Distribution system, which can display a single source on up to hundreds of displays with cable runs of up to 300ft without signal loss.
