Userful has developed software that allows a single PC to function as a video wall controller. The software is installed on an Intel Core i7 PC along with optional HDMI input cards. Low-cost zero client players are connected to each display in the video wall. This enables the PC to drive multiple video walls of up to 25 screens each with 4K source resolution. Content can be displayed from web pages, live streams, desktops, and content management systems. Zones can be preset within the video wall to mix different content sources. The solution simplifies setup and management of video walls and can support control room applications.
