While HDMI-compliant devices are becoming more widespread, DVI display devices are still used in the majority of traffic control centers and other large-scale, centralized control rooms. ATEN designed the VM5404D: a seamless matrix switch for DVI signals that offers a straightforward and economical solution to route any of four DVI video sources to any of four DVI displays, avoiding signal instability, quality deterioration, and other problems associated with interface converters. This visual accessory uses an FPGA matrix design to enable continuous video streaming, real-time control, and robust signal transfer. The VM5404D easily translates multiple input resolutions into a variety of output resolutions, giving viewers the highest image quality across all monitors, thanks to a built-in high-performance scaler. The switch also includes video wall functionality, as well as an intuitive online interface that allows you to establish up to eight connection profiles for easy layout customization. Any control center that has to transmit various sources to several monitors should use the VM5404D.
