The Comprehensive HDMI 4x4 Matrix Switcher with RS232 switches between four HDMI inputs and routes one of them to four HDMI displays, carrying both the video and audio of the signal. Resolutions up to 1080pHD and multichannel audio are supported.
Switching can be done via an included remote, by RS232 or by front panel buttons. DVI to HDMI adapters can be used for both input and output.
