The VisionDVI-DL, dual-link DVI capture card, is supplied with a powerful software application for configuring the format of the input sources and displaying the data. Simply connect your video source into the card, run the VisionDVI-DL application to automatically detect the video source resolution and display the captured video in a window on your desktop.

Wall Control-red presents a representational window of the entire display wall showing position and size of video windows. Datapath Wall Control-red video wall software enables you to configure your multi-screen display, launch video overlays and create a video wall layout configuration. With the full version it is possible to save layouts and recall them for future use and also operate Wall Control video wall software on a remote PC via a network connection.
