The SW VGA Series are VGA switchers with two, four, six, or eight inputs. They are designed for applications where multiple high resolution computer video or HDTV component video signals must be switched to one or two displays. The eight input SW VGA switcher offers dual buffered video and audio outputs, which eliminates the additional cost of a VGA and audio distribution amplifier for dual-display applications. The SW VGA Series switchers are ideal for small to mid-sized applications where high resolution switching is needed.
