    The Model VS-4A is a versatile and compact 4 input x 1 output VGA & audio switch. It supports PC resolutions to 1600x1200 or HD resolutions to 1080p. The unit allows one monitor to be switched between four video and audio sources. The switched output can be selected via front panel push-button, through RS-232 serial port, or automatically by scanning and detecting active video on the inputs. In 'Auto' mode, the user can also assign priority to any of the inputs, whereby if all video inputs are active, the selected input would have precedence. The switched output can be blanked (with audio muted) or unblanked via the front panel or through the serial port. Optional rackmount brackets are also available.
