Userful™ is a converged software appliance (operating system and application software bundled together for easy deployment and maintenance) for AV & IT professionals that lets you centrally control large numbers of displays, content sources and desktops from your web browser. Userful's appliance enables an ordinary PC to do extraordinary things, like driving a whole building of desktops, digital signage, touch screens, virtual machines and video walls all from a single Userful host over a standard Ethernet network. From high-performance video walls, to virtual desktops, to Power-over-Ethernet touch screens -- it's never been easier.
