After careful review of different display technologies—including specialized hardware solutions for video walls, as well as digital signage—the team at EMT learned about Userful’s video wall solution. Right away, they appreciated the simplicity and flexibility of the solution. According to Jose Manuel Fernandez, Systems Engineer at EMT, “the support for real-time interactive content, seeing how simple it was to manage, and also the possibilities to easily switch content sources between displays, was what really convinced me that Userful was the solution we were looking for.”
Userful fit EMT’s needs perfectly in part because it’s able to handle a virtually unlimited number of inputs, and it can also easily scale the number of outputs it can offer. This is unique in the video wall space and is a result of Userful’s architecture. Userful leverages the network to deliver content from the PC onto a video wall. With Userful, a single PC can support a video wall of up to 60 displays. Each display has a simple and cost effective zero client device on the back that connects to the PC through the local area network. Userful software turns that PC into an appliance that is easily managed through a browser. Using the browser based interface, customers can easily pull content from almost any available source including network sources in real time. The solution can display everything from video to a full screen browser to a desktop and even a series of virtual desktops—multiple independent desktop sessions running on the same PC. According to Fernandez “the integration for virtual machines in the system made the solution even better for us.”
EMT deployed a 3x3 video wall with nine 55” LG commercial displays, all running from a single Intel Core i7 PC and 32 GB of RAM, which is securely located away from the wall itself in a locked room, with a monitored environment—which helps to prolonged the PC’s lifespan. EMT added HDMI capture cards to pull in external content sources to display on the video wall in real time.
