And if two displays aren’t enough? Connect multiple DualHead2Go units to create all sorts of cost-effective, versatile HD display configurations. DualHead2Go units can be used to improve and simplify digital signage applications such as digital menu boards, shopping mall kiosks, and ambience-enhancing installations—to name a few.
