The 4x4 Atlona HDMI Matrix Switcher with RS-232 and IR Remote is designed to work as a switcher for multiple sources and displays. With a maximum bandwidth of 2.25Gbps, this device will support a sharp and highly defined video in multiple resolutions of up to 1080p. Because it is a matrix switcher, it allows any input to be routed to any output; or the same input to be routed to all outputs or any combination. It completely eliminates the need to constantly move around video input and output cables. RS-232 control allows the switcher to be controlled by systems like Crestron or any computerized software/hardware control systems. Atlona"s AT-HDMI-44M comes with IR remote control as well. The Atlona AT-HDMI-44M is now HDMI 1.3 compliant.
