The 4-Port VGA Splitter with Audio from ATEN is a VGA splitter that allows a single VGA video and audio signal to be distributed to four output displays with independent stereo control. The splitter supports up to 450 MHz of video bandwidth providing video quality with supported resolutions up to 1920x1440. The splitter features serial control through the built-in RS-232 port which allows the splitter to be controlled through a high-end controller or PC. Designed for us in conference rooms, training facilities, and multi-display broadcasting the splitter can be cascaded up to three levels allowing the single video signal to be sent across numerous video displays while still sustaining high quality resolutions.
