With the appeal of its digital signage suite now extending beyond the print houses it was designed for, developer Caldera has announced a powerful new version upgrade. Vital hardware statistics – including usage and temperature for the CPU, hard drive and motherboard – are collated within a simple interface that allows users to identify, pre-empt and resolve problems before they occur. An online, form-based template will also make it easier for novice operators to include the visual dynamism of Flash content within their installations, adding to existing HTML5 capability. Users can also now specify and place widgets on the screen, each containing live or static content to be run simultaneously within zones in the visual area. With Caldera's much-liked drag-and-drop interface, v3.0 owners can create sophisticated templates for quick-service restaurants, retail and a variety of internal communications applications with a few clicks. Variable Display 3.0 represents a major functionality boost for adopters, adding remote hardware monitoring, screen layout features and a Flash customization service to help deliver hard-hitting campaigns.
