Common display configurations

Individual video screens

The most common digital signage application is individual video screens displaying information. Often multiple screens in various locations are networked through a digital signage system, so they all show the same information and can be updated at the same time.

Touchscreens

The same technology you see at ATMs and information kiosks can supplement your digital signage setup when you want to give the viewer the ability to get information on demand. You can use standalone touchscreens or touch bezel overlays that affix to existing plasma or LCD screens and make them interactive.

Touchscreens actively engage people and interact with them, making them an ideal medium for advertising and distributing information.

Video walls

A video wall of four, six, nine, or even more video screens working together to make a single display saves money as compared to a single very large screen. These large, tiled video displays are frequently used in public areas such as stadiums, airports, and shopping malls.

Screens designed for use in video walls have narrow bezels to minimize gaps between active display areas. They usually have connections to daisychain power and video signals between screens to simplify cabling. Although large video walls require special controllers, small video walls can be set up just using multimonitor video cards.

KVM-switched tiling

Some KVM switches enable you to tile images from as many as four video cameras and/or computer screens on a single display while providing control over individual windows. This application is often used in security or control room situations.
