While HDMI-compliant devices are becoming more popular, the majority of traffic control centers and other large-scale, centralized control rooms still rely on DVI display devices. In order to avoid signal instability, quality deterioration and other factors associated with interface converters, ATEN created the VM5404D: A seamless matrix switch for DVI signals that offers an easy and affordable way to route any of 4 DVI video sources to any of 4 DVI displays. The VM5404D includes seamless switching that employs an FPGA matrix architecture to ensure continuous video streaming, real-time control and stable signal transmission. With a built-in high-performance scaler, the VM5404D easily converts various input resolutions into a array of output resolutions, giving viewers the best image quality across all displays. The switch also integrates video wall functionality with an easy-to-use web GUI that lets you create 8 connection profiles for convenient layout customization. The VM5404D is the ideal solution for any control center streaming multiple sources to multiple displays.
