The Gefen HD Video Wall Controller is the perfect solution for entertainment and digital signage applications in retail outlets, clubs, trade shows, control centers, building lobbies, and other similar venues. The HDTV displays are installed in a 2x2 configuration to create a large video wall. It accepts a single HDCP-compliant HDMI source and divides it onto four equally sized displays, each with resolution up to 1080p. The HD Video Wall Controller has very good bezel compensation ability and can accommodate any display bezel width. Power on, Lock on, and menu navigation control buttons are accessible via front panel and the handheld IR remote control, as well as via RS-232 and IP (web server interface, Telnet, and UDP). On-screen Graphical User Interface simplifies the system configuration.
